What kind of meissner corpuscle and pacinian corpuscle are the skin receptors?
Correct answer: D. Encapsulated nerve ending
- A. Free nerve ending
- B. Hot
- C. Cold
- D. Encapsulated nerve ending
Explanation
Meissner corpuscles are encapsulated nerve endings to enhance sensitivity to light touch and low-frequency vibrations. The encapsulation provides mechanical support and protects the nerve endings, allowing for precise discrimination of tactile stimuli. Additionally, it facilitates rapid adaptation to changes in tactile stimuli, enabling quick responses to dynamic touch sensations.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
