Recording of the myotatic reflex in session 1 of electromyogram (EMG) teaching, s, Point of contact of tendon hammer with tendon, b, onset of skeletal muscle electrical activity, c, onset of movement of limb This stretch is picked up by the muscle spindle The impulse from the a-motoneuron crosses the neuromuscular junction and results in an end ...

Question: 1. Explain what could be a mechanism by which Jendrassik maneuver produces bigger myotatic reflex. 2. What is the function of the ventricular system of the brain? b) Describe the location of each ventricle and cerebral aqueduct in relation to brain structures. 3. What are two areas in the cerebral hemispheres responsible for speech?

ANSWER÷ The myotatic reflex is a significant clinical reflex. A similar circuit delivers the automatic, or stretch, reflex. At the point when the doctor taps the patellar ligament with a sledge, this activity causes the knee extensor muscle to sudden …View the full answer

What is the myotatic reflex? The tendency of a muscle to contract when it is initially stretched. The tendency of a muscle to relax when it is initially stretched. The tendency of a muscle to contract when the opposing muscle is relaxed. The tendency of a muscle to relax when the opposing muscle is contracted.

Stretch reflex B. Baroreflex C. Chemoreflex D. Myotatic reflex Mean arterial blood pressure decreasing and heart rate increasing correspondingly best describes which of the following reflexes? A. Stretch reflex

11) What happens during the myotatic reflex? a) Muscle spindle fibers are stretched generating receptor potentials firing neurons afferents that synapse with the motor neuron by exciting it, the motor neuron will send out potentials of action by contracting the muscle b) The fibers of the Golgi tendon organ are stretched, generating receptor potentials firing the afferent neurons that …
