Question

What kind of a receptor allows us to recognize objects by touch? What are the 4 types?

a) Thermoreceptors; Cold, warm, hot, and neutral
b) Nociceptors; Mechanical, thermal, chemical, and polymodal
c) Photoreceptors; Rods, cones, bipolar cells, and ganglion cells
d) Mechanoreceptors; Merkel cells, Meissner's corpuscles, Pacinian corpuscles, and Ruffini endings

Answer 1

Mechanoreceptors are the type of receptor that allows us to recognize objects by touch. The four types of mechanoreceptors are Merkel cells, Meissner's corpuscles, Pacinian corpuscles, and Ruffini endings.

Step-by-step explanation:

The receptor that allows us to recognize objects by touch is called mechanoreceptors. There are four types of mechanoreceptors: Merkel cells, Meissner's corpuscles, Pacinian corpuscles, and Ruffini endings.

Merkel cells respond to light touch and the discrimination of shapes and textures. Meissner's corpuscles detect touch, low-frequency vibration, and flutter. Pacinian corpuscles detect transient pressure and high-frequency vibration. Ruffini endings detect skin stretch, joint activity, and warmth.
