Sensory Receptors and Modalities

Flashcards covering key terminology and definitions related to sensory receptors and their modalities.

Exteroceptors

Sensory receptors that detect stimuli from outside the internal environment, such as pressure and temperature.

Interoceptors

Sensory receptors that monitor internal body conditions, like blood pressure and pH levels.

Proprioceptors

Receptors that provide information about body position and movement by detecting muscle tension and joint position.

Mechanoreceptors

Sensory receptors that respond to mechanical pressure or distortion, involved in sensing touch, vibration, and sound.

Thermoreceptors

Receptors that detect changes in temperature, both internal and external.

Chemoreceptors

Receptors that respond to chemical stimuli, such as those that detect odors and tastes.

Nociceptors

Pain receptors that are activated by damaging stimuli and are responsible for the sensation of pain.

Special senses

Senses that have specialized organs and systems dedicated to specific stimuli, such as vision and hearing.

General senses

Senses that are more widely distributed throughout the body and include touch, temperature, and pain.

Olfactory system

The sensory system responsible for the sense of smell, bypassing the thalamus and sending signals directly to the brain.

Vestibulocochlear nerve

The cranial nerve responsible for hearing and balance, comprising the cochlear and vestibular components.
