Which type of sensory structures carrying the touch sensations are present in papillae extending into the ridges of the fingertips?
Correct answer: C. Meissner's Corpuscles
- A. Hair end organs
- B. Pacinian corpuscles
- C. Meissner's Corpuscles
- D. All of these
Explanation
Meissner's corpuscles (or tactile corpuscles) are a type of mechanoreceptor. They are touch receptors. They are a type of nerve ending in the skin that is responsible for sensitivity to light touch. Therefore, option C is correct.

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.
