The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse before that impulse reaches the brain. [1] Reflex arcs can be. Monosynaptic i.e., contain only two neurons, a sensory and a motor neuron.
Sep 13, 2023 · How do reflexes work? Generally, reflexes work through a reflex arc. A reflex arc is the line of communication within the body that prompts a reflex response. The arc uses sensory nerves (to ...

The anatomical pathway of a reflex is called the reflex arc. It consists of an afferent (or sensory) nerve, usually one or more interneurons within the central nervous system, and an efferent (motor, secretory, or secreto-motor) nerve. Most reflexes have several synapses in the reflex arc. The stretch reflex is exceptional in that, with no ...
Reflexes can be spinal or cranial, depending on the nerves and central components that are involved. The body uses both spinal and cranial reflexes to rapidly respond to important stimuli. All reflex arcs include five basic components; (1) a receptor, (2) a sensory neuron, (3) an integration center, (4) a motor neuron, and (5) an effector.
A reflex action is a protective, automatic and rapid response to a stimulus. It follows the same general sequence as a normal reaction but often it does not involve the brain. Instead, the spinal ...

That causes a signal to travel along a nerve to your spinal cord. There a waiting motor neuron sends out an automatic command to contract the muscle attached to the tendon. When the muscle contracts, your leg kicks. You are born with such “hard-wired” reflexes. Most are located in the spinal cord. But some are in the motor centers of your ...
