Question 1

Characteristics of nerve tissue

Answer 1

Nerve tissue provides rapid and specific communication between organs in the body.
The two major components of nerve tissue are highly specialized cells called neurons and support cells, called the neuroglia, or glial cells. Neurons, similar to muscle cells, are electrically excitable.

A. Sensory neurons, which gather information from receptors.
B. Interneurons that form a communicating network between neurons.
C. Motor neurons convey impulses from the nervous system to the effector cells.
