B. A motor neuron only innervates one muscle fiber.
C.

Respuesta :

Answer:A motor neuron only innervates one muscle fiber.

Explanation:

One motor neuron can innervate several muscle fibres.

The combination of one motor neuron innervating several muscle fibre is called a motor unit.

The number of  skeletal muscle fibres innervated is called the innervation ratio.

Group of  the motor unit works together to coordinate contraction is a single muscle cell.

Motor neurons transmit impulses from the spinal cord to skeletal and smooth muscles. They form rod-shaped clusters that run parallel to the axis of the cord for spinal cord segments.
