Question

a tactile receptor composed of highly coiled dendrites surrounded by modified schwann cells and a fibrous capsule is a
root hair plexus.
lamellar corpuscle.
tactile (meissner) corpuscle.
tactile (merkel) disc.
bulbous corpuscle.

Explanation:

• Root hair plexus: Composed of free nerve endings around hair follicles, not highly coiled dendrites with modified Schwann cells and fibrous capsule.
• Lamellar corpuscle: Large, onion - shaped, detects deep pressure and vibration, structure different from described.
• Tactile (Meissner) corpuscle: Located in dermal papillae, has highly coiled dendrites, surrounded by modified Schwann cells and fibrous capsule, detects light touch.
• Tactile (Merkel) disc: Consists of a Merkel cell and a nerve ending, for light touch and texture, structure not matching.
• Bulbous corpuscle: Detects skin stretching, structure not as described.

Answer:

tactile (Meissner) corpuscle.
