Question

Classify the receptor for gustation:
general or special?
interoceptor, exteroceptor, or proprioceptor?
mechanoreceptor, chemoreceptor, thermoreceptor, nociceptor, or photoreceptor?

Answer 1

Classify the receptor for gustation:

General or special? - Special

interoceptor, exteroceptor, or proprioception? - Exteroceptor

mechanoreceptor, chemoreceptor, thermoreceptor, nociceptor, or photoreceptor? - Chemoreceptor

Classification of receptors:

>> Based on the anatomical positions: General and special

General senses: temperature, pain, touch pressure, proprioception.

Special senses: Vision, Hearing, taste, smell, balance.

>> Sensory receptors are of three types (based on the origin of the stimulus): interoceptor, exteroceptor, or proprioception

Exteroceptors receive stimuli from the external environment of the body (out of the body). Ex. Visual (sight), Auditory (hearing), Olfactory(smell), tactile (touch), and taste (Gustatory).

Interoceptors receive stimuli from the inside body. Ex. Viscera, state of the hollow organs and glands (ex. stomach pain), blood pressure.

Proprioceptors detect the posture and movements of the body.

>> Based on the type of stimulus (modality of stimulus): thermoreceptors, mechanoreceptors, nociceptors, photoreceptors, and chemoreceptors.

Thermoreceptors - Temperature

Mechanoreceptors - Touch, Pressure

Nociceptors - Pain

Photoreceptors - Vision

Chemoreceptors - Taste, smell
