Question

Quizplus · Accepted Answer

The knee-jerk reflex is a spinal reflex and is controlled by interneurons in the spinal cord. The synaptic gap refers to the space between neurons where neurotransmitters are released and received. The myelin sheath is the fatty coating on axons that helps speed up neural transmissions, but it does not directly control the knee-jerk reflex. The parasympathetic nervous system is responsible for controlling rest and digestion, and does not play a role in the knee-jerk reflex.
