Human Reflex Physiology Exam 100% solved

Human Reflex Physiology Exam 100% solved Define reflex: - ANSWERRapid, predictable, involuntary motor responses to stimuli; they are mediated over neural pathways called reflex arcs. Name five essential components of a reflex arc: - ANSWERReceptor, sensory neuron, integration center, motor neuron, and effector. In general, what is the importance of reflex testing in a routine physical examination? - ANSWERReflex testing is an important diagnostic tool for assessing the condition of the nervous system. Distorted, exaggerated, or absent reflex response may indicate degeneration or pathology of portions the the nervous system, often before other signs are apparent. Reflexes classified as somatic reflexes include a - ANSWERAbdominal reflex, achilles reflex, corneal reflex, crossed-extensor reflex, gag reflex, patellar reflex, and plantar reflex. Of these, the simple stretch reflexes are _______ and ________ , and the superficial cord reflexes are _________ and __________. - ANSWERAchilles reflex and patellar reflex; corneal reflex and plantar reflex. Reflexes classified as autonomic reflexes include ________ and _________. - ANSWERCiliospinal reflex and pupillary light reflex. Name two cord-mediated reflexes - ANSWERPatellar reflex and cross- extensor reflex Name two somatic reflexes in which the higher brain centers participate - ANSWERSuperficial cord reflexes and pupillary light reflexes Can the stretch reflex be elicited in a pithed animal (that is, an animal in which the brian has been destroyed)? Explain. - ANSWERYes, Even without the brain a stretch reflex only needs an afferent control center, and motor fibers to be elicited. These components still stay intact if the brain has been destroyed
