Reflex arc questions and answers
Reflex arc questions and answers-Anatomy and Physiology questions and answers;Q1 Describe reflex action and reflex arc Answers REFLEX ACTION A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain
Reflex Arc Questions
Anatomy and Physiology questions and answers Reflex Arc As we move throughout our day, it is likely that we will encounter sharp objects, hot surfaces or other items that may very quickly damage our integumentary system and potentially the tissues that lie beneath it If we relied on only our brain to manage our reactions to such encountersA reflex arc made up of sensory organ, sensory neuron, motor neuron and effector organ is involved Multiple synapses are involved Only two synapses are involved Stimulus passses to the opposite side, the left side of the brain controls the right side of the body and vice versa Stimulus, neurons, action all on the same side of the bodyHint A reflex action is a type of animal behaviour which is responsible for involuntary and sudden response to a stimulus in case of a dangerous situation The spinal cord plays a major role in the reflex arc Complete answer A reflex action is an involuntary, sudden and instantaneous movement in response to a stimulus against a dangerous situation

Answer (1 of 5) Reflex arc is a type of emergency mechanism in your nervous system Suppose you touch a hot plate, by mistake To keep your body safe, your arm has to be moved away from the point of contact with the plate That can be done when theQ Receives message from CNS about how an muscle or gland ought to react in response to an object, event, or personA reflex is an involuntary response to a stimulus A reflex arc is composed of five elements Which of them transmit impulses to the central nervous system?

Reflex arc, neurological and sensory mechanism that controls a reflex, an immediate response to a particular stimulusThe primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action The simplest arrangement of a reflex arcA)It occurs in conjunction with a withdrawal reflex B)When flexor muscles of the lower limb contract due to stepping on a sharp object, the extensor muscles in the same limb are inhibited C)It occurs in reflexes in both the upper and lower limb D)When flexor muscles of the lower limb contract due to stepping on a sharp object, the extensorThe knee jerk reflex 5

Reflex arcs can be seen as hardwired features adapted to optimize highvalue survival stimulusresponse action patterns & as such strictly limited in scope, but highly conserved In the case of cephalopods, it cannot be that simple, by a long shot Please be sure to answer the question Provide details and share your research!A) Can be used clinically to determine area of spinal cord damage b) Each dermatome is only served by a single spinal nerve c) Complete anesthesia of a single dermatome often requires blocking three adjacent spinal nerves d) Dermatomes are designated based on the cranial or spinal nerve that serves that area of the skin The answer to this question depends which reflex arc was activated, without knowing the exact reflex arc one should assume the answer as multifactorial and relate to this (or similar) table (Source Fundamental Neuroscience for Basic and Clinical Applications, by
