Solved in 2 steps
- 10. PUT THE FOLLOWING STEPS OF THE REFLEX ARC IN THE CORRECT ORDER BY Agonist muscles are stimulated and antagonist muscles are inhibited. An electrical impulse reaches the post-central gyrus, and you interpret the sensation NUMBERING THEM. sonist muscles are stimulated and antagonist muscles are inhibited. as pain. "Ouch!" Leg extension occurs, and you move your foot off the piece of glass. Pain receptors are stimulated. The electrical impulse travels in your leg via many motor neurons. The impulse reaches the spinal cord and forks into two waves. One wave of electriaity makes a U-turn and the other begins its journey toward the brain. The message of stimulation (in the form of an electrical impulse) travels in the leg via many sensory neurons. You step on a piece of glass.3. Can a person has absent of Achilles reflex while maintaining knee reflexes?1. What was the effect of muscle fatigue on your ability to produce the patellar reflex? 2. In general, what is the importance of reflex testing in a routine physical examination? 3. What is Babinski’s sign? Describe the normal plantar reflex.

Spinal cord damage interrupts descending motor tracts that act to suppress the activity of spinal motor neurons. Use this information, and the muscle stretch reflex pathway, to explain why someone with a spinal cord injury can have muscle spasms below the level of the injury. a banm11.
