Yona, you creatively posted in your concluding paragraph the sometimes overlooked, but very important aspects of how the pituitary gland impacts key things such as proper sleep, exercise and overall hormonal balance in the body.

[Joseph Matthews]

I also like how Lesly inserted an additional element to this very complex and technical subject of the pituitary gland by commenting on the importance of an accurate understanding of this subject and how it affects the medical interpreter’s overall performance is such cases.

[Joseph Matthews]

The pituitary gland is one of the key components of the human body’s endocrine system. This gland, which is also termed as being the “master gland,” is small in size and is located just below the hypothalamus region of the brain. Its tiny size notwithstanding, the pituitary gland plays a key role in regulating many essential bodily functions by producing and then releasing a cadre of hormones that influence growth, metabolism and reproduction.
The pituitary gland is divided into two main parts: (1) The anterior lobe (adenohypophysis) and (2) the posterior lobe (neurohypophysis). Each lobe releases different hormones however, both are under the control of the hypothalamus, which sends signals to regulate their activity. Herewith is a brief breakdown and the importance of each:
The anterior pituitary produces several important body hormones:
• Growth hormone (GH) which stimulates growth and development of bones and tissues
• Thyroid-stimulating hormone (TSH) – regulates the thyroid gland which controls metabolism
• Adrenocorticotropic hormone (ACTH) – this stimulates the adrenal glands to produce cortisol which is key for stress response and energy regulation
• Prolactin (PRL) promotes milk production in breastfeeding women
• Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) – these control sexual development and reproductive functions in both males and females
The posterior pituitary stores and releases:
• Antidiuretic hormone (ADH) – which helps control the water balance in the body by regulating the amount of water that is reabsorbed by the kidneys.
• Oxytocin – which is involved in childbirth and lactation as well as emotional bonding and general social behaviors.
Because of its widespread hormonal influence, any dysfunction in the pituitary gland can lead to serious conditions, which include growth disorders, infertility, thyroid imbalances as well as adrenal insufficiency.
Finally, the pituitary gland is vital for maintaining homeostasis which is the state of balance among all body systems needed for the body to function properly. In this role, it acts as a type of central command center, helping the body to effectively and efficiently respond to internal and external changes through its hormonal output.

Cristina, I liked the way you addressed the introduction to this issue in the form of a general “environmemnt scan-overview” to inform the reader of the main points that will follow in sequence. Both an interesting and effective communication technique. Well dome!

[Joseph Matthews]

Leonisa, you are able to address and sumarize a complex and an important subject such as this in half the words than it took me and I do applaud this. Congrats!

[Joseph Matthews]

The male and female reproductive systems are both essential for human reproduction and, together, form one of the human body’s most important systems. However, they each differ significantly in terms of anatomy, function and roles within the reproductive process as is addressed in the synopsized format below.
The female reproductive system is designed to produce eggs, called ova, support fertilization and nurture a developing fetus throughout pregnancy. The principal female organs include the ovaries, fallopian tubes, uterus, cervix, vagina, and external genitalia. The ovaries release one egg each month during the menstrual cycle and also produce the hormones estrogen and progesterone, which regulate menstruation and pregnancy, amongst other functions. When the fertilization process occurs in the fallopian tube, the egg becomes implanted into the lining of the uterus (called embryogenesis) where the embryo forms which is then followed by the process of morphogenesis in which the fetus begins to take shape. When the fetus reaches sufficient maturity, the cervix dilates and contractions of the uterus propel it through the birth canal.
The male reproductive system is primarily responsible for producing, storing, and delivering sperm. Key external components include the penis and scrotum, while important internal organs include the testes (which produce sperm cells), epididymis, vas deferens, seminal vesicles, prostate gland, and the urethra. The sperm cells mature in the epididymis, travel through the vas deferens, mix with fluids from the seminal vesicles and prostate gland to form semen, which is expelled through the urethra during ejaculation.
The male system continuously produces sperm, while the female system follows a cyclical process and is capable of supporting and sustaining new life. Both systems are hormonally regulated and work together to make reproduction possible.
Also worth noting are the diseases that affect both the female and male reproductive systems. The key disease for both is cancer. In the case of the female reproductive system – it affects the ovaries, uterus, cervix and breast. Ovarian cancer tends to be the most impacting one as there is no standard screening test for it and it is usually diagnosed only when the cancer has reached an advanced stage. In the case of the male reproductive system – the most common is prostate cancer but there are also forms of penile and testicular cancer as well.
Finally – there is the subject of infertility which affects both sexes. In the case of the female, it arises from the inability to ovulate, conceive and give birth to an infant. In the case of the male – it is chiefly the inability to produce sperm cells.

[Joseph Matthews]

The same goes for the approach that Cristina provided in her description of each component of the nerve cell and its functional importance following the A-B-C rule of keeping the text “Applicable”, “Brief” and “Clear”. This indicates to me, a lay person in this subject of the nervous system, that you possess sound base knowledge in this area which is a key leveraging factor.

[Joseph Matthews]

Leonisa – once again – as in the previous case of arteries, veins and the chambers of the heart functions – you are able to synopsize the description and importance of the components of this very technical and complex subject of the nerve cell into a succinct format without forgoing substantive content. Bravo!

[Joseph Matthews]

The nerve cell, which equivalent term is a neuron, is the fundamental unit of the nervous system and is specially designed to transmit signals and information rapidly and efficiently between different parts of the body and can be metaphorically described as the body’s electrical wiring system.
The neuron is divided into a series of key components with each one individually performing a fundamental role in the receiving, processing, and transmitting of signals that allow the body and brain to function properly. Herewith is the functional profile and importance of each component of the neuron:
• Cell Body – Which Equivalent Term is Soma
Functional profile: The cell body contains the nucleus and other sub-cell components such as mitochondria and ribosomes which are responsible for maintaining the neuron’s health and metabolic functions. The nucleus houses the neuron’s genetic material which control protein synthesis and other essential activities.
Importance: Without the soma, the neuron would literally not be able survive much less effectively process information.
• Dendrites
Functional profile: These are short plant-like extensions emanating from the soma that receive chemical or electrical signals from neighboring neurons and are covered with receptors that detect neurotransmitters.
Importance: The dendrites increase surface area connections which allow the neuron to integrate multiple signals all at one time making complex processing possible.
• Axon
Functional profile: The axon is a long, thin wire-like projection that carries electrical impulses away from the soma toward other neurons and muscles.
Importance: Some axons are extreme in length which can extend from the spinal cord all the way to the toes. This ensures rapid transmission of nerve impulses and information over very long distances within the body.
• Myelin Sheath
Functional profile: The axon is covered by a myelin sheath which is a fatty-type insulating layer that is produced by specialized glial cells as in the case of Schwann cells or oligodendrocytes. Myelin greatly increases the speed of electrical transmission by allowing the impulse to jump between gaps in the sheath called Nodes of Ranvier.
Importance: Without myelin, these signal jumps between the gaps in the Nodes of Ranvier would be much slower and less efficient that can lead to nervous system disorders such as multiple sclerosis.
• Axon Terminals – Which Equivalent Term is Synaptic Boutons
Functional Profile: The axon terminals are the round type structures at the endpoint of the neuron. When an electrical impulse reaches the terminal, it triggers the release of neurotransmitters into the synaptic cleft.
Importance: These neurotransmitters then bind to receptors on the next cell, which are absolutely essential in the efficient communication from the neuron to the muscles and between neurons themselves.
Synapse
Functional Profile: The synapse is the junction gap between the axon terminal of one neuron and the dendrite of another neuron.
Importance: The synapse enables essential chemical and electrical communication to occur which, in turn, allows for networks of neurons to pass signals and impulses rapidly and efficiently across key brain functions and the nervous system as a whole.

[Joseph Matthews]

Following up on Leonisa’s approach to this subject – Cristina also follows the same approach addressing both subjects in clear, distinct and informative paragraph with a focus on an efficient word count. Again – this requires time, attention to the key details and a sound knowledge of the subject at hand.

[Joseph Matthews]

Leonisa – this issue of arteries, veins and the importance of the four chambers of the heart is quite complex one, especially in the case of a layperson like me. I admire the way in which you addressed both subjects in a clear and descriptive format while keeping it succinct which is not a simple task.

[Joseph Matthews]

Arteries and veins serve different roles and are an integral part of the body’s circulatory system which key function is the proper flow of blood, oxygen, nutrients and other gases both to and from the cells of the body as well as eliminating harmful waste products such as carbon dioxide. Herewith is a breakdown of the key differences between the two:
• Arteries carry oxygen-rich blood from the heart to the rest of the body. They are large and have thick elastic walls which is key in order to withstand the high pressure from the heart’s pumping action. A good case-in-point here is the Aorta.
• Veins, on the other hand, have a different directional function in that they carry oxygen-poor blood back to the heart. A good case-in-point here is the Superior Vana Cava.
• Another difference is that veins have thinner walls than do arteries and often have valves to prevent the blood from flowing backwards, especially as pertains to the arms and legs.
The heart is a muscular organ, it is composed of four specific chambers which pump the blood through the network of arteries and veins. These chambers are crucial for maintaining efficient blood circulation. Herewith is the breakdown of these four chambers and their specific function:
• The right atrium receives oxygen-poor blood returning from the body
• The right ventricle pumps that blood to the lungs for oxygenation
• The left atrium receives the newly oxygenated blood from the lungs
• The left ventricle then pumps the oxygen-rich blood to the entire body
This separation into four chambers is the key factor in ensuring that oxygen-rich and oxygen-poor blood do not mix as well as maximizing the efficiency of oxygen delivery throughout the body.

[Joseph Matthews]

Lesly, I do appreciate how you placed emphasis on the importance of honing and maintaining current one’s knowledge of the medical terms in both languages because – like maintaining muscular fitness – this keeps them from atrophying and the same goes for the brain and the information the medical interpreter needs to retain same.

[Joseph Matthews]

Leonisa – you know to add sound back-up to a specific point in enhancing good mental retentions by citing clear examples in a good diet such as Omega-3, green vegetables, protein-rich fish, eggs, nuts, etc.

[Joseph Matthews]

Cristina – I liked the way you conveyed the approach to idea mapping to enhance mental retention with the emphasis you placed on ideas, pictures, concepts, etc. which is a new concept for me as this goes beyond and above the traditional concept of flow-charting.
