Is tendon reflex monosynaptic or polysynaptic
WitrynaThe simplest reflexes are monosynaptic, such as the stretch or myotatic reflex. More complex polysynaptic reflexes are involved in many regulatory and protective functions--these include autonomic as well as somatic reflexes. Ocular autonomic reflexes include the oculocardiac, pupillary, accommodative and lacrimatory reflexes. WitrynaMonosynaptic reflexes are composed of only two neurons between the stimulus and target cell, while polysynaptic reflexes contain three or more neurons.

Is tendon reflex monosynaptic or polysynaptic
Did you know?
Witryna7 lip 2024 · The monosynaptic stretch reflex, or sometimes also referred to as the muscle stretch reflex, deep tendon reflex, is a reflex arc that provides direct communication between sensory and motor neurons innervating the muscle. … This contraction allows the muscle to resist the force that initially caused the reflex. WitrynaThe 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] Relex arcs can be Monosynaptic ie contain only two neurons, a sensory and a motor neuron.
Striking of the patellar tendon with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle. This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L3 or L4 in the spinal cord, completely independent of higher centres. From there, an alpha motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction. This contraction, coordinated with the relaxat… WitrynaSimple reflexes involving a single synapse between two neurons are termed monosynaptic, whereas reflexes involving two or more synapses are termed polysynaptic. We will examine several types of somatic and autonomic reflexes because of their clinical significance. ... the stretch reflex, the Golgi tendon reflex, …
WitrynaThe patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. Many animals, most significantly humans, have been seen to have the patellar reflex, including dogs, cats, horses, and other mammalian species. [1] Mechanism [ edit] WitrynaMonosynaptic reflexes The simplest reflexes are those with single afferent and efferent neurons and a single synapse (monosynaptic reflexes). The minimum delay across …

In the case of peripheral muscle reflexes (patellar reflex, achilles reflex), brief stimulation to the muscle spindle results in contraction of the agonist or effector muscle. By contrast, in polysynaptic reflex pathways, one or more interneurons connect afferent (sensory) and efferent (motor) signals.
