Question

Name the parts labeled a, b, c, d, e, f, g and h in the neuron drawn below.

Answer 1

Hint: Neuron is made up of many different parts and each of them is essential for the transferring of signal from one neuron to another. Each of these neurons work in association for the successful transmission of signals.

Complete answer:
The neuron is the structural and functional unit of the brain. They help in the transmission of information to other nerve cells along with other organs or muscles. The neurons are contained within the nervous system. Their structure is divided into a cell body, an axon, and dendrites. The neurons are electrically excitable and they communicate to other neurons via synapses. Neurons are divided into two categories namely sensory neurons and motor neurons. Sensory neurons respond to stimuli such as touch and sound and send signals to the spinal cord or brain. The motor neurons control a wide variety of functions ranging from muscle function to glandular output. The names of the structures labeled from a to h are as follows:
a. Dendrite.
b. cell body.
c. Nucleus
d. Axon.
e. Myelin.
f. Schwann cell.
g. Node of Ranvier.
h. Axon terminal.

Note: The signaling that takes place through the neurons are partially electrical and partially chemical. They are electrically excitable because they maintain voltage across their plasma membranes. Neurons develop from neural stem cells during the process of development. However when a person reaches adult stages, neurogenesis stops in some parts of the brain. They perform a wide variety of functions in biological systems. In addition to this ,they also exist in different forms. They form the most important part of the nervous system along with the glial cells.
