Question

nevus tissue explanation
​

Answer 1

Explanation:

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.

Answer 2

Answer:

All cells possess the ability to respond to  stimuli. However, cells of the nervous tissue  are highly specialised for being stimulated and then transmitting the stimulus very rapidly  from one place to another within the body. The  brain, spinal cord and nerves are all composed  of the nervous tissue. The cells of this tissue  are called nerve cells or neurons. A neuron  consists of a cell body with a nucleus and  cytoplasm, from which long thin hair-like  parts arise. Usually each neuron  has a single long part (process), called the  axon, and many short, branched parts (processes) called dendrites. An individual  nerve cell may be up to a metre long. Many  nerve fibres bound together by connective  tissue make up a nerve.  The signal that passes along the nerve fibre  is called a nerve impulse. Nerve impulses allow  us to move our muscles when we want to. The  functional combination of nerve and muscle  tissue is fundamental to most animals. This  combination enables animals to move rapidly  in response to stimuli.
