What is reflex action and reflex arc?

Question

Answer

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

Answer

Reflex action is a fast action which is caused due to the sudden change in the environment in other words it is for response to dangerous environmental condition the path followed by the electrical impulse generated from the reflex action is called reflex arc the reflex arc include motor neurone sensory neurone CNS message to the brain receptor

Answer

Reflex action is a nerve mediated autonomic involuntary, spontaneous response to stimulus with a specific receptors to the organism.

reflex arc is the pathway taken by stimulus to travel from receptor organ to effector.

Answer

Reflex action is an involuntary action by the body. ... A reflex arc is a neural pathway that controls an action reflex. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.

Answer

It's simply our fast response ...without completing the thinking process..

Answer

A reflex arc is a neural pathway that controls an action reflex. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex action occurs. There are two types of reflex arc: autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles). A reflex action is an automatic and inborn response to a stimulus that involves a nerve impulse passing from a sensory nerve cell to a muscle or gland without reaching the level of consciousness. Simple reflexes include sucking, swallowing, blinking, scratching, and the knee jerk. Most reflexes consist of complex patterns of many unconsciously coordinated muscular actions that form the basis of much instinctive behavior in animals. Examples include walking, standing, the cat's righting reflex

Answer

I only know the meaning of reflex action . it means that involuntary actions . such as sneezing , yawning , heart beat , etc.

Answer

It is a involuntary action in response to a stimulus. lt takes spontaneously without thinking. for example eyes adjust when exposed to bright light.
peripheral nervous systems ( PNS) is a system of nerve
....................................................
which connects central nervous system( CNS) ( includes
...................................................
brain and spinal cord) with other path of body . this coordination of spinal cord and PNS results of reflex action
Areflex arc is the pathway in which impulses travel during the reflex action.

I hope it's is helpful for us

thank you

Answer

Reflex action --- Involuntary actions in response to external or internal stimuli are termed as reflex actions.

Reflex arc --- The structural and functional unit that carries out and controls the reflex action is called a reflex arc.
