Concept explainers
To describe: The general anatomical design of a muscle spindle and its physiological function.
Introduction: The reflexes are immediate or automatic involuntary actions for the response of an external stimulus. The reflex of external stimuli sends the signals through nerves to reach the spinal cord for an immediate action. The reflexes share the four important criteria, such as quick (involves minimal synaptic delay), involuntary (automatic in nature), stereotyped reactions of muscles (predictable responses), and stimulation (response against sensory input). The somatic reflexes have a specialized sensory receptor called proprioceptor that maintains the movement of the body as well the position by controlling the skeletal muscles.
