Explanation:
a. Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
b. Head injuries may cause bleeding in the brain tissue and the layers that surround the brain (subarachnoid hemorrhage, subdural hematoma, epidural hematoma). Symptoms of a head injury can occur right away or may develop slowly over several hours or days.
c. A typical neuron consists of a cell body (soma), dendrites, and a single axon. ... The term neurite is used to describe either a dendrite or an axon, particularly when the cell is undifferentiated. Most neurons receive signals via the dendrites and soma and send out signals down the axon.
