|
The local circuits in the spinal cord that are fully capable of controlling the timing and coordination of complex locomotion are called
|
|
central pattern generators.
|
|
|
the mesencephalic locomotor region.
|
|
|
the flexion-crossed extension reflex.
|
|
|
reciprocal innervation.
|
Explanation:
Detailed explanation-1: -The key circuit elements in the spinal locomotor networks are the rhythm-generating circuits and the pattern-generating circuits, which include circuits that control bilateral muscle activity, and circuits that control flexor–extensor muscles in limbed animals.
Detailed explanation-2: -The central pattern generator (CPG) for respiration is located in the brainstem and produces rhythmic synaptic drive for motoneurons controlling respiratory muscles. Based on respiratory nerve discharge, the respiratory cycle can be divided into three phases: inspiration, postinspiration and stage 2 expiration.
