Question

The spinal cord achieves the function of locomotion through _______ 

Multiple Choice 

•  groups of neurons called central pattern generators

•  pools of spinal neurons that receive input from multiple sources

•  involuntary stereotyped responses to stimuli

•  sensory neurons in the brain that initiate walking and determine its speed, distance and direction

•  a flexor reflex

Answer 1

A. groups of neurons called central pattern generators.

The four principle functions of the spinal cord include the conduction of nerve impulses, neural integration, locomotion, and reflexes. Central pattern generators of the spinal cord are the neural networks that help to perform rhythmic movements like swimming, walking and hoping. Pools of spinal neurons that receive inputs from multiple sources is the neural integration, while a quick, involuntary, stereotyped response to a stimulus is called a reflex. Flexor reflex helps in flexor muscle contraction.
