Detailed explanation-1: -The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles). It can be further subdivided into somatic and visceral divisions. The somatic motor division carries signals to the skeletal muscles.
Detailed explanation-2: -The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre. Where they sit together is called a neuromuscular junction.
Detailed explanation-3: -The spinal cord is a vital aspect of the CNS found within the vertebral column. The purpose of the spinal cord is to send motor commands from the brain to the peripheral body as well as to relay sensory information from the sensory organs to the brain.
