What kind of nociceptors are the skin receptors?
Correct answer: A. Free nerve ending
- A. Free nerve ending
- B. Stray nerve endings
- C. Blind nerve ending
- D. Encapsulated nerve ending
Explanation
Nociceptors have free nerve endings to maximize sensitivity to potentially harmful stimuli such as pain, temperature extremes, and tissue damage. These unencapsulated nerve endings enable nociceptors to respond quickly and extensively to a wide range of noxious stimuli, facilitating rapid detection and transmission of pain signals to the central nervous system.

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.
