AP PSYCHOLOGY

Detailed explanation-1: -Blinking of eyes is not a reflex action, but it is involuntary action.

Detailed explanation-2: -There are different types of reflexes, including a stretch reflex, Golgi tendon reflex, crossed extensor reflex, and a withdrawal reflex.

Detailed explanation-3: -Sweating is not a reflex action. It is primarily a means of temperature regulation. But, salivation on seeing food, hand withdrawal because of the needle and blinking of the eyes due to bright light are all examples of reflex actions.

Detailed explanation-4: -A reflex arc defines the pathway by which a reflex travels-from the stimulus to sensory neuron to motor neuron to reflex muscle movement. Brain is not involved in any reflex action (e.g., knee-jerk relfex) while the muscle spindle, inter neuron and motor neuron are the part of reflex arc.

Detailed explanation-5: -The reflex shown in this figure is called a 3-neuron reflex because it requires three types of neurons: a sensory, an interneuron, and a motor neuron. It is also called a withdrawal reflex because it is commonly involved in withdrawing from painful stimuli. Withdrawing from painful stimuli does not require thought.
