Verified step by step guidance

Understand that free nerve endings are a type of nerve receptor found in the body that are responsible for detecting pain, temperature, and mechanical changes.

Recognize that these nerve endings are part of the peripheral nervous system and are distributed throughout the body, but their density varies in different tissues.

Consider the function of free nerve endings: they are most effective in areas where the body needs to detect environmental changes quickly, such as temperature and pain.

Identify the skin as a primary organ for sensory reception, where free nerve endings are highly concentrated to detect external stimuli like heat, cold, and pain.

Conclude that the skin, being the body's largest organ and primary interface with the environment, has the highest abundance of free nerve endings compared to internal organs like the pancreas, heart, or liver.
