Nerve endings are primarily responsible for feeling tactile stimuli because they are specialized structures that convert physical stimuli from the environment into electrical signals that the nervous system can interpret. These nerve endings, located throughout the skin, are particularly dense in areas that are highly sensitive to touch, such as the fingertips and lips. They detect various sensations, including light touch, pressure, pain, and temperature, allowing for a full range of tactile experiences.

On the other hand, while hair follicles and the dermis play vital roles in skin structure and some sensory functions, they do not specifically serve the primary purpose of transmitting tactile stimuli. Hair follicles are involved in the growth and health of hair, and the dermis contains various components, including blood vessels and sweat glands, that support skin function. The subcutaneous layer, comprising fat and connective tissue, primarily provides insulation and cushioning rather than direct sensory perception.
