3. Answer the following questions in 30-40 words:
a) How does the structure of a nerve cell help with its function?
Answers
So, to review, neurons are specialized cells of the nervous system that transmit signals throughout the body. Neurons have long extensions that extend out from the cell body called dendrites and axons. Dendrites are extensions of neurons that receive signals and conduct them toward the cell body.

Answer:
While neurons have a lot in common with other types of cells, they're structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells. Neurons can also receive these signals via rootlike extensions known as dendrites.
Nerve cells are composed of tiny branches called dendrons which branch into further even smaller extensions called dendrites. They also have a nucleus surrounded by cytoplasm, a cell membrane and an axon. ... This insulation is what adapts the neuron to carry electrical impulses from one place in the body to another.
