"We covered the anatomy and physiology of the arc reflex, eye and ear. The student practiced drawing and labeling the different structures that are part of the arc reflex. We then worked on memorization techniques. Although the specific example for the arc reflex provided in the text was the knee-jerk reflex, I gave him other similar examples such as the elbow reflex and the ankle reflex that health care professionals assess to determine some health conditions. He was able to assimilate the notion that the arc reflex is a short circuit used by the body in emergency situation for a body part to react very fast such as when one accidentally touches a hot pot or when one's hand comes close to a fire. He was able to understand that because of that, the arc reflex does not involve the brain as the hot sensation for example felt at the tip of one's fingers would take too long to go up to the brain, get analyzed, then come all the way down to the motor neurons attached to the muscles that would cause one's upper extremity to retract for protection.
He practiced labeling the different portions of the retina on a sketch. He now also has an analogy to remember the reason (protection) for the eye to constrict when a light is flashed during an eye exam. He practiced drawing and labeling the pathways of the right optic nerves and left optic nerves to the cortex, emphasizing that only the nasal ones (middle) cross each other. The temporal ones stay their course laterally until they reach the cortex.
I drew the ear so that he could practice labeling the different parts. We went over the similarities in the physiology of the semicircular canals and cochlea and the different roles that they play. I recommended to the student that he prints similar drawings so that he could exercise labeling.
The student now feels very confident to review the materials by himself in preparation for the exam."
