Which structure in the dermis helps in the sensation of touch?

• A. Hair follicles
• B. Nerve endings
• C. Blood vessels
• D. Collagen fibers

Answer: (B)

The correct choice highlights the role of nerve endings in the dermis, which are essential for the sensation of touch. The dermis contains a variety of specialized nerve endings that respond to different types of stimuli. Mechanoreceptors, for example, are specifically designed to detect pressure, vibration, and texture, allowing the skin to sense fine details when touched. These nerve endings transmit signals to the brain, which interprets them as tactile sensations.

While hair follicles also play a role in touch sensitivity through their associated nerve endings, they are not the primary structures responsible for detecting touch sensations actively. Blood vessels are crucial for supplying nutrients and regulating temperature, and collagen fibers provide strength and elasticity to the skin but do not contribute to sensory perception. Thus, nerve endings are the key structures involved in transmitting tactile information from the dermis, making them fundamental to the sensation of touch.
