Reflex Arcs definitions Flashcards

A monosynaptic reflex initiated by muscle spindles in response to unexpected stretching, causing muscle contraction.

Sensory receptors within muscles that detect changes in muscle length and trigger the stretch reflex.

A polysynaptic process that relaxes the antagonistic muscle during a stretch reflex to ensure smooth movement.

A polysynaptic reflex triggered by Golgi tendon organs in response to excessive tension, leading to muscle relaxation.

Sensory receptors located in tendons that detect tension and initiate the tendon reflex.

A process where the antagonistic muscle contracts during the tendon reflex to maintain balance and prevent overextension.

An ipsilateral reflex causing rapid contraction of flexor muscles in response to a painful stimulus, leading to withdrawal.

A contralateral reflex that extends the opposite limb to maintain balance during a flexor reflex.

Referring to reflex actions occurring on the same side of the body as the stimulus.

Referring to reflex actions occurring on the opposite side of the body as the stimulus.

A reflex arc involving a single synapse between a sensory and a motor neuron.

A reflex arc involving multiple synapses, typically including interneurons.

A muscle that opposes the action of another muscle, often relaxed during reflex actions.

A neuron that transmits impulses between other neurons, especially in reflex arcs.

A neuron that transmits sensory information from receptors to the central nervous system.
