The receptor in the reflex arc of a stretch reflex are 'muscle spindles' which are spindle shaped receptors distributed throughout the belly of the muscle.
when the muscle gets stretched , muscle spindle is stimulated and it sends proprioceptive impulses via sensory afferent fibers in posterior root to anterior horn cells of the spinal cord. Motor impulses from anterior horn cells via motor efferent fibers in anterior root to muscle.
What else can I help you with?
The patellar reflex is a type of?
The patellar reflex is a type of stretch reflex that involves tapping the patellar tendon to elicit a contraction of the quadriceps muscle and extension of the knee. This reflex helps to maintain balance and stability.
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
Why doesn't the patellar reflex happen when your leg is straight?
The patellar reflex, also known as the knee-jerk reflex, doesn't occur when your leg is straight because the muscle involved in the reflex, the quadriceps, is relaxed when the leg is fully extended. The reflex response occurs when the muscle is slightly stretched, triggering a signal to the spinal cord that leads to the reflexive contraction of the quadriceps.
What movement would you expect to occur during the Achilles reflex?
During the Achilles reflex test, you would expect to see plantar flexion of the foot, where the foot points downwards, in response to tapping the Achilles tendon. This reflex is a protective mechanism that helps maintain posture and balance in the lower extremities.
What reflex inhibits gastric motility when ileum becomes overdistended?
The gastroileal reflex inhibits gastric motility when the ileum becomes overdistended. This reflex ensures that the stomach doesn't empty too quickly into an already overfull small intestine, allowing for proper digestion and absorption to occur.
Dynamic and static stretch reflex?
differentiate between a dynamic stretch reflex and a static stretch reflex
The patellar reflex is a type of?
The patellar reflex is a type of stretch reflex that involves tapping the patellar tendon to elicit a contraction of the quadriceps muscle and extension of the knee. This reflex helps to maintain balance and stability.
What properties are not of the stretch reflex?
It is a disynaptic reflex
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
What reflex is the knee jerk reflex an example of?
knee jerk aka patellar reflex is an example of a stretch reflex
Do you still have a stretch reflex with a cervical nerve injury?
Yes, you may still have a stretch reflex with a cervical nerve injury.
The patellar knee jerk reflex is an example of?
Patellar reflex is an involuntary, deep tendon and myotatic reflex
Can you willfully inhibit a stretch reflex?
The stretch reflex is a normal, automatic response of the body to a sudden stretch of a muscle, controlled by the spinal cord. While it can be modulated, inhibiting it will require overriding the spinal reflex arc, which can be challenging to do willfully without external intervention. Techniques such as relaxation exercises or gradual stretching may help reduce the intensity of the stretch reflex.
What is an example of a stretch reflex triggered by passive muscle movement?
knee jerk reflex
When does the activation of a motor neuron occur in a stretch reflex?
The activation of a motor neuron in a stretch reflex occurs when muscle spindles detect a stretching of the muscle, leading to the generation of action potentials. These signals are transmitted to the spinal cord, where they synapse directly with alpha motor neurons. This direct connection allows for a rapid response, causing the muscle to contract and counteract the stretch almost immediately. This reflex arc is crucial for maintaining posture and balance.
The receptors of the inflation reflex are most sensitive to?
stretch
Do stretch reflex have interneuron?
Yes, the stretch reflex involves a simple monosynaptic pathway between sensory neurons and motor neurons without the involvement of interneurons in the spinal cord.
