What is the Name of the receptor for the stretch reflex?
The receptor for the stretch reflex is called the muscle spindle. Muscle spindles are sensory receptors located within the belly of muscles, and they detect changes in muscle length and the rate of that change. When a muscle is stretched, the muscle spindle initiates the stretch reflex, leading to a contraction of the muscle to resist the stretch. This reflex helps maintain posture and balance.
Which reflex would be most likely to inhibit the performance of a forward roll?
The reflex most likely to inhibit the performance of a forward roll is the stretch reflex, specifically the muscle spindle reflex. When the muscles involved in the roll, such as the neck, back, and abdominal muscles, are stretched beyond their normal range, the muscle spindle receptors send signals to the spinal cord to contract the muscles to prevent injury. This contraction can create resistance and hinder the smooth execution of the forward roll. Additionally, the protective withdrawal reflex may also play a role in inhibiting movement if the body senses potential danger during the roll.
Do people have Knee jerk reflex when they sleep?
No, the knee jerk reflex is typically not active during sleep as it requires conscious input from the brain. The reflex is a reaction to a sudden stretching of the muscle, detected by the sensory neurons in the muscle spindle, which then sends a signal to the spinal cord to elicit the reflex. This process is not typically active during deep sleep stages.
Why does not the patellar reflex happen when your leg is straight?
When the leg is straight, the muscle spindle receptors in the quadriceps muscle are not stretched enough to stimulate a reflex response. The reflex occurs when the muscle is quickly lengthened, activating the sensory receptors in the muscle and sending a signal to the spinal cord to trigger a reflexive contraction of the quadriceps muscle.
In response to a muscle being overstretched a muscle spindle generates a somatic spinal reflex that ultimately causes what response?
Both contaction of the agonist muscle and relaxation of the antagonist muscle
What structure forms in prophase along which the chromosomes called?
The answer is Spindle Fibers.
Is a gag reflex a somatic reflex?
No, a somatic reflex are the reflexes of the skeletal muscle movements. The gag reflex is considered to be an autonomic reflex.
What is the receptor of the Achilles reflex?
Hit tendon nociceptors in tendo-achilles. It goes to the CNS by sciatic nerve, then it goes to interneurons in spinal cords S1-S2. Then it goes to Alfa motor n, tibial nerve from sciatic nerve to lead to the gastrocnemius muscle.
A fan like microtubule structure that helps separate the chromosomes is a?
the spindle
273° what angle?
Answer Reflex Angle
What reflex is the knee jerk reflex an example of?
knee jerk aka patellar reflex is an example of a 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.
