Answer:
The shape of a nerve cell in a nerve cell in an animal is different from the shape of a muscle cell. A nerve cell is long and branched whereas a muscle cell is pointed at both ends and has a spindle shape.
Muscle and nervous tissues rely on electrical activity to function. Muscle tissue generates force to provide movement, and nervous tissue is responsible for transmitting electrical and chemical signals throughout the body. Muscle and nervous tissues are considered excitable tissues.
