Fill in the blank:  The sensory stretch receptors of the knee-jerk reflex are located in the _______________________ muscle.

Compare the number of motor neurons in a somatic and autonomic reflex arc.

In the patellar tendon reflex, what is the name of the receptors being struck by the reflex hammer?

Identify the nerves of the arm

V. Triceps Jerk a Reflex that assesses the nervous tissue between (and including) the C6, C7, and C8 nerve roots. b. It can be elicited by supporting your partner's arm with the elbow flexed at a 90° angle, sharply striking the posterior surface of the upper arm approximately 2 inches above the olecranon (bony "tip" of the elbow). c. Normal response: The triceps should twitch, and the elbow should extend. Label the feedback mechanism for this reflex. THEREH Binepe Incepa

Can indivuals with spinal cord injury be able to demonstrate the muscle reflexes? Explain

Fill in the blank:  ______________________ muscles in the limbs are the effectors of a withdrawal reflex.

During the exam you ask the patient to shrug their shoulders against your hands and notice the muscle strength is weak.  Upon palpation of the neck, you also notice the sternocleidomastoid is weak when the patient turns their head against your hand.  Which nerve is most likely affected?
