Which of the following receptors do not consist of free nerve endings?
A) Warm receptors
B) Meissner's corpuscles
C) Cold receptors
D) Nociceptors
E) All of these receptors consist of free nerve endings.
Meissner's Corpuscles
Sensitive mechanoreceptors located in the papillary layer of the dermis, particularly in areas like the fingertips and lips, responsible for sensitivity to light touch.
Free Nerve Endings
Sensory receptors found throughout most of the body that respond to pain, temperature, touch, and pressure.
- Differentiate various sensory receptors by examining their response to stimuli and their operational functions.

Final Answer :
B
Explanation :
Meissner's corpuscles are located in the dermal papillae of hairless skin and consist of specialized nerve endings surrounded by connective tissue cells. They are responsible for sensitivity to light touch and vibration. The other options listed consist of free nerve endings, which are the most common type of sensory receptor in the skin and are responsible for detecting temperature, pain, and pressure.
