MICROANATOMY

Detailed explanation-1: -If you touch something that is very hot, your hand moves away quickly before you even feel the pain. You don’t have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment).

Detailed explanation-2: -The “Hot-Stove Rule” of Douglas McGregor gives a good illustration of how to impose disciplinary action without generating resentment. This rule draws an analogy between touching a hot stove, and undergoing discipline. When you touch a hot stove, your discipline is immediate, with warning, consistent, and impersonal.

Detailed explanation-3: -Coughing, yawning and blinking of eyes are examples of reflex actions.

Detailed explanation-4: -An important reflex initiated by cutaneous receptors and pain receptors is the flexor reflex. We have all experienced this reflex after accidentally touching a hot stove or a sharp object, as we withdraw our hand even before we consciously experience the sensation of pain.

Detailed explanation-5: -The stimulus is touch, your pain receptor is the sensor that senses it and relays it to the nervous system (spinal cord and brain) which is the coordinator. The coordinator makes the decision of how to react, and then commands the hand muscles (effector) to move the hand away (response).
