what does a nerve look like
A nerve is like a cobweb or like a tree's roots. The nerves spread out everywhere throughout your body.Guess what?........... Theirs only one nerve in your body but it spreads out as a tree's branches and takes up the whole body. the nerves are mostly pinkish but sometimes are multicolored. the cell body (Head) has a nucleus within it. the nerves have several points where it branches into dendrites (like the roots on a tuber) the head then extends into a narrow extension which is coated with Myelin sheath. the narrow extension then branches out into dendrites which is a mode of contact to another neuron.
Each nerve is a cordlike structure that contains many axons. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium.The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium.n the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is potentially misleading since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
