chemoreceptors
Taste and smell
Chemoreceptors are sensory cells or organs that detect chemical substances and trigger physiological responses.
They enable taste and smell, and monitor internal chemistry—oxygen levels in the blood, glucose concentrations, pH balance.
When chemoreceptors in the carotid artery sense low oxygen, they signal the brain to increase breathing rate.
gustation
Sense of flavor
- papillaeSmall tissue protrusions
- tongueOral muscle for taste
- salivaMouth's digestive secretion
- supertasterHeightened gustatory sensitivity
olfaction
Sense of scent detection
- aromaPleasant distinctive smell
- odorPerceived atmospheric emission
- pheromonesSpecies-specific chemical messengers
- anosmiaTotal olfactory loss
homeostatic
Innermost organ tissue
- hypoxiaInsufficient tissue oxygenation
- brainstemLower neural trunk
- hypothalamusSubthalamic regulatory brain region
