Sep 12, 2022 · The monosynaptic stretch reflex, sometimes called the muscle stretch reflex or deep tendon reflex, is a reflex arc that facilitates direct communication between sensory and motor neurons innervating the muscle.

When a reflex arc in an animal consists of only one sensory neuron and one motor neuron, it is defined as monosynaptic, referring to the presence of a single chemical synapse.

Nov 3, 2023 · The monosynaptic stretching reflex and polysynaptic inverse stretching reflex are the two basic units of the spinal motor actions. These reflexes do not generate isolated patterns, but instead, are executed to coordinate specific muscle groups.

Sep 12, 2022 · The monosynaptic stretch reflex, sometimes called the muscle stretch reflex or deep tendon reflex, is a reflex arc that facilitates direct communication between sensory and motor neurons innervating the muscle.

Aug 4, 2023 · A monosynaptic reflex, such as the knee jerk reflex, is a simple reflex involving only one synapse between the sensory and motor neurone. The pathway starts when the muscle spindle is stretched (caused by the tap stimulus in the knee jerk reflex).

Sep 25, 2023 · The monosynaptic stretch reflex works by the rapid and automatic activation of sensory neurons in response to the stretching of a muscle, which stimulates motor neurons to contract the same muscle, resulting in rapid muscle contraction and subsequent reflex movement.

A synchronous electric stimulus to the afferent nerve has much the same effect as a tap on the tendon. The resulting monosynaptic reflex is termed the Hoffman reflex (shortened to the H reflex). There are no interneurones: the reflex arc is monosynaptic.

Jan 11, 2025 · Monosynaptic and polysynaptic reflexes are two distinct types of neural pathways that mediate rapid, automatic responses to stimuli. Monosynaptic reflexes involve only a single synapse between a sensory neuron and a motor neuron, creating a direct and rapid response.

Monosynaptic reflexes are the simplest type of reflex arc, consisting of a single synapse between a sensory neuron and a motor neuron. This direct connection allows for a quick and efficient response to stimuli, making monosynaptic reflexes crucial for maintaining homeostasis and reacting to immediate threats.

Referring to direct neural connections (those not involving an internuncial neuron); for example, the direct connection between primary sensory nerve cells and motor neurons characterizing the monosynaptic reflex arc.

Sep 12, 2022 · The monosynaptic stretch reflex, sometimes called the muscle stretch reflex or deep tendon reflex, is a reflex arc that provides direct communication between sensory and motor neurons innervating the muscle.

In this paper, we present a comprehensive description of the principles, specific operational details, and key steps involved in tracing anterograde and retrograde monosynaptic connections.

The simplicity of monosynaptic sensory-motor circuits make them an effective model system to study the molecular mechanisms underlying the different steps of neural circuit formation such as axonal elongation, synaptic specificity, synapse formation, and circuit maintenance.

When the arc consists of one sensory and motor neuron, it is referred to as a monosynaptic reflex (with ‘monosynaptic’ referring to one synapse). Monosynaptic reflexes include, for example, the biceps and triceps reflexes, and patellar stretch reflex or knee jerk (see figure below).

In a monosynaptic reflex, there is no involvement of interneurons. Instead, the signal enters the spinal cord through a sensory neuron and synapses directly with a motor neuron. An example of this type of reflex is the patellar reflex.

The monosynaptic reflex represents the most extensively investigated proprioceptive reflex system. Monosynaptic reflex responses can be recognized clearly by the characteristic short-onset latency of the EMG responses, which alter muscle stretch in different motor conditions.

Reflex arcs that contain only two neurons, a sensory and a motor neuron, are considered monosynaptic. Examples of monosynaptic reflex arcs in humans include the patellar reflex and the Achilles reflex.

A simple monosynaptic reflex consists of an afferent input that synapses in the spinal cord and returns to the extremity through an efferent output (Fig. 2-12). Upper motor neurons inhibit the output of the efferent signal; therefore, if reflexes are increased, the examiner should suspect a decrease in upper motor influence.

Apr 1, 2000 · The principle of the monosynaptic reflex used as a tool to explore the excitability of the motoneurones (MNs) is explained and the general methodology of the H reflex is described.

A monosynaptic pathway in neuroscience refers to a neural pathway where an ipsilateral Type I neuron directly inhibits a contralateral kinetic Type I neuron. AI generated definition based on: Progress in Neurobiology , 2005
