|
receptors in the skin are connected to nerve cells, but receptors in the eye are not.
|
|
receptors in the eye respond to a different type of input than receptors in the skin.
|
|
there are many more sensory receptors in the skin than receptors in the eye.
|
|
only the sensory receptors in the eye transmit signals directly to the brain.

Detailed explanation-1: -Sensory receptors in the skin have a different structure than sensory receptors in the eye. The most reasonable explanation for the difference in the structure of these receptors is that – receptors in the skin are connected to nerve cells, but receptors in the eye are not.
Detailed explanation-2: -The human eye has three different types of light-sensitive receptors: rods, cones and photosensitive ganglion cells.
Detailed explanation-3: -Sensory receptors exist in all layers of the skin. There are six different types of mechanoreceptors detecting innocuous stimuli in the skin: those around hair follicles, Pacinian corpuscles, Meissner corpuscles, Merkel complexes, Ruffini corpuscles, and C-fiber LTM (low threshold mechanoreceptors).
Detailed explanation-4: -A cutaneous receptor is the type of sensory receptor found in the skin ( the dermis or epidermis). They are a part of the somatosensory system. Cutaneous receptors include mechanoreceptors (pressure or distortion), nociceptors (pain), and thermoreceptors (temperature).
Detailed explanation-5: -Skin receptors (known as mechanoreceptors and cutaneous receptors also) enable us to detect the location of the stimulus when an outer force (i.e., touch, pressure, stretching, vibration, motion) applied and deformed our skin (Table 3.4) Each of the receptors is sensitive a specific type of stimulus.
