the answer i found was the foot. sorry if i am wrong.
Another place to consider is the fold of the arm. If you have someone touch your arm while you are looking and then have them without you looking touch several places on your are it is difficult to know when they return to the exact place they originally touched. You do have nerves in your arms but the endings are few.
Areas that are more associated with sensory systems such as hands feet have more nerves
Tactile corpuscle are the nerve endings in the skin that respond to the lightest touch. They are most concentrated on the fingertips and lips.
Skin is the largest organ of the body and also has the most nerve endings.
It is the tips of the fingers that have the highest density of nerve endings.
Burns can expose the most nerve endings. Pain from burns is pretty substantial.
The clitoris has approximately 8,000 nerve endings, making it the most sensitive part of a person's body. These nerve endings are responsible for transmitting sensations of pleasure.
Free nerve endings functions as cutaneous receptors ( is a sensory receptor present on dermis or epidermis ). Present in vertebrates for sense of pain. they are frequently found on skin. *Muscle spindles
The fingertips and lips are considered to be the most sensitive parts of the body due to the high concentration of nerve endings found in these areas, allowing for heightened tactile and sensory perception.
The clitoris is typically considered the sexual organ with the most nerve endings, specifically in the glans. This makes it highly sensitive and responsive to sexual stimulation.
The fingertips have the highest density of sensory structures, such as touch receptors and nerve endings. This high concentration of sensory structures allows for precise discrimination of touch and texture.
The clittoris. It is the area of a women's genitals that creates the most sexual feeling.
The cornea is one of the most sensitive tissues of the body, it is densely innervated with sensory nerve fibres via the ophthalmic division of the trigeminal nerve by way of 70 - 80 long ciliary nerves; and short ciliary nerves derived from the oculomotor nerve. The nerves enter the cornea via three levels, scleral, episcleral and conjunctival. Most of the bundles give rise by subdivision to a network in the stroma, from which fibres supply the different regions. The three networks are midstromal, subepithelial/Bowman's layer, and epithelium. The receptive fields of each nerve ending are very large, and may overlap. Corneal nerves of the subepithelial layer converge and terminate near the apex of the cornea in a logarithmic spiral pattern.[5]
