D) sensory neurons.

Question

Quizplus · Accepted Answer

Muscle fibers are made up of effector cells, which are specialized to generate mechanical force by contracting. Neurilemma cells are a type of glial cell that form the myelin sheath around axons in the peripheral nervous system. Connector neurons and sensory neurons are types of neurons that transmit signals within the nervous system and do not directly contribute to muscle contraction.
