A _______ is a Nerve That Controls Muscle Contractions

Question

A _______ is a nerve that controls muscle contractions.
A) motor nerve
B) sensory nerve
C) nucleus
D) contractile

Accepted Answer

A motor nerve controls muscle contractions by sending signals from the brain and spinal cord to the muscles. Sensory nerves, on the other hand, detect sensory information from the environment and send it to the brain and spinal cord. The nucleus is a structure found in cells, and contractile refers to the ability of a muscle to contract.
