WebJan 17, 2024 · The stretch reflex (myotatic reflex) is a muscle contraction in response to stretching within the muscle. This reflex has the shortest latency of all spinal reflexes. It is a monosynaptic reflex that provides automatic regulation of skeletal muscle length. When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases.

WebIn biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action [1] and nearly instantaneous response to a stimulus. [2] [3] The simplest reflex is initiated by a … WebAs a result of its activation through the process of synaptic transmission, action potentials are elicited in the interneuron. An action potential in the inhibitory neuron leads to the release of a chemical transmitter substance that inhibits the flexor motor neuron, thereby preventing an improper movement from occurring.
WebThe three semicircular canals (horizontal, anterior, and posterior) lie in three different planes at approximately right angles to each other so that rotations of the head about any axis can be sensed. The planes of the three semicircular canals approximately correspond to the planes of action of the three pairs of extraocular muscles (Fig. 7 ...
