A)the forearm is the most sensitive area of the body.
B)skin receptors are found in varying concentrations, reflecting the sensitivity of the body areas.

D)temperature sensitivity is greatest in the chest and trunk areas.

Question

Quizplus · Accepted Answer

Skin mapping has shown that different areas of the body have varying concentrations of skin receptors, which reflects the sensitivity of those areas. For example, the fingertips have a high density of touch receptors while the soles of the feet have more pressure receptors. Pain receptors also vary in concentration but are not uniform throughout the body. Temperature sensitivity is not necessarily greatest in the chest and trunk areas.
