Week 5 – Discussion Board 2

[Art Liebl]

Research the components of the nerve cell and importance of each one of them.  Reply to two fellow students by Monday.

[Alejandra Gana]

A nerve cell, or neuron, is the basic unit of the nervous system. it sends and receives messages throughout the body.
The cell body controls the neurons activities and contains the nucleus.
Dendrites receive signals from other neurons and carry them to the cell body.
The axon carries messages away from the cell body to other parts of the body.
The myelin sheath covers the axon to protect it and make messages travel faster.
Nodes of Ranvier are small gaps thar help speed up nerve impulses. At the end of the axon, axon terminals pass messages to the next cell through a tiny gap called the synapse. Each part of the neuron works together to ensure fast and efficient communication in the nervous system.

[Luanna Vieira Rosa]

I agree with what you said and I like how you explained everything.

[Brian Pacheco]

Love your explanation!

[Emily Arias-Perez]

I agree!

[Dayane Malone]

Thank you for sharing!

A nerve cell, also known as a neuron, is what helps the brain and body send messages to each other. The cell body is the main part of the neuron and has the nucleus, which controls what the cell does and keeps it alive. Dendrites are little branches that take in messages from other nerve cells and bring them to the cell body. The axon is a long fiber that carries messages away from the cell body to other cells. Some axons are covered by a myelin sheath, which helps the messages move faster. At the end of the axon are axon terminals, which send out neurotransmitters (chemicals that pass messages) through a small gap called the synapse. All the parts of a neuron work together to help us think, move, feel, and react to whatever is happening around us.

[Brian Pacheco]

Great job explaining this!

[Dayane Malone]

Its amazing to think that “all the parts of a neuron work together to help us think, move, feel, and react to whatever is happening around us.”

[Brian Pacheco]

A nerve cell, also known as a neuron is the basic structural and functional unit of the nervous system. Its function is to receive, process, and transmit information through electrical and chemical signals. The cell body is the main part and inside contains the nucleus, which is like the control center. Dendrites are extensions of the cell body that receive signals from other neurons and transmit them to the cell body. The Axon conducts electrical impulses and may be covered by a myelin sheath which increases the speed of nerve impulse transmission. Nodes of Ranvier help speed up the conduction of nerve impulses. At the end of the axon, there are axon terminals that pass messages to the next cell through a tiny gap called the synapse. Each part of the Neuron plays an essential part in the nervous system.

[Shannelys Guzman]

You did a great job explaining!

[Dayane Malone]

A nerve cell is one of the most important cells in the body because it helps send messages between the brain, spinal cord, and the rest of the body. These messages control everything we do—from moving our fingers to feeling pain or happiness. A neuron has several main parts, and each one has a special job that helps the cell work properly.

The cell body also known as the soma, is the center of the neuron. It contains the nucleus, which controls the cell’s activities and keeps it alive. You can think of it like the “brain” of the neuron, managing what happens inside the cell.

Next are the dendrites, which look like little branches coming out of the cell body. Their job is to receive signals or messages from other nerve cells and carry them toward the cell body. They’re like tiny antennas that pick up information.

Then there’s the axon, a long, thin fiber that carries messages away from the cell body to other neurons, muscles, or glands. It acts like a highway that helps signals travel quickly over long distances in the body. Some axons are covered with a myelin sheath, a fatty layer that works like insulation around a wire. This helps the messages travel faster and more efficiently.

At the end of the axon are axon terminals (or nerve endings). These are small structures that send signals to the next cell using chemicals called neurotransmitters.

Each part of the neuron is important because they all work together to help our body communicate. Without neurons and their parts, our brain wouldn’t be able to control movement, memory, feelings, or even basic body functions like breathing

[Emily Arias-Perez]

I like how you explained it.

[Shannelys Guzman]

Love your breakdown of the different parts!

[Emily Arias-Perez]

The components of a nerve cell, or neuron, are essential for their function and the overall operation of the nervous system. Each part plays a specific role in the transmission of signals and the integration of information. Here’s a breakdown of the key components and their functions.
Cell Body (Soma): The central part of the neuron that contains the nucleus and is responsible for protein synthesis and energy production. It integrates signals from dendrites and decides whether to generate an action potential.
Dendrites: Tree-like extensions that branch out from the cell body. They receive signals from other neurons and convert them into electrical impulses. The dendritic spines on dendrites contain neurotransmitter receptors, facilitating synaptic connections.
Axon: The longest part of the neuron, responsible for transmitting electrical signals away from the cell body. Axons can be covered by a myelin sheath, which speeds up the transmission of nerve impulses.
Synaptic Terminal: The point where information is transmitted to target cells. It is where neurotransmitters bind to receptors on the post-synaptic neuron, triggering an electrical impulse in the adjacent cell.
The importance of these components lies in their ability to form complex networks that enable rapid information transfer throughout the body.

[Shannelys Guzman]

A neuron is a nerve cell. A nerve cell is made up of three parts the cell body, dendrites, and axon. It has one main function a major one and that is to receive information and transmit the possibility of an action for our whole entire body. From reacting to a deer running across the road to a blinking. These occur because our nerve cells speak to each other carrying information. Our body has over a 1000 different kinds of neurons.

The cell body also called the soma is the cells way of living, its life support. It contains a nucleus and many other specialized organelles. The dendrites are short and bushy fibrous roots that transmit information.They can be found around the soma and can be more than one set of dendrites. The axon works as the way of communication on a trail-like structure delivering electrical impulses from the cell body through the axon to pass info to another neuron. Neurons have one main axon. Axons join the cell body by a junction called the axon hillock. Axons are covered in myelin sheaths. Myelin sheath is a fatty substance of liquid and protein that layers the axons causing insulation. When the signals travel through the axons it has the node of ranvier to make it faster as it delivers a message via synapse. Synapse is when a neuron delivers a chemical or electrical signal to another neuron via the axon.
