AP PSYCHOLOGY

Detailed explanation-1: -somatic sensation Sensations arising from the skin-such as touch, pressure, cold, warmth, and pain-and from the muscles, tendons, and joints-such as the position of the limbs and pain-are known as somatic sensations.

Detailed explanation-2: -Dorsal column pathway for somatic senses. Primary afferent sensory neurons have cell bodies in the dorsal root ganglia and long axons that terminate in receptors at the skin.

Detailed explanation-3: -SI processes both tactile and proprioceptive sensory information. SI is located in the postcentral gyrus of the cerebral cortex and contains four distinct regions, called Brodmann’s areas 3a, 3b, 1, and 2.

Detailed explanation-4: -Somatic pain occurs when pain receptors in tissues (including the skin, muscles, skeleton, joints, and connective tissues) are activated. Typically, stimuli such as force, temperature, vibration, or swelling activate these receptors. This type of pain is often described as: cramping.
