Sensory Receptors: Mechanoreceptors, Thermoreceptors, and More

Mechanoreceptors

Detect mechanical pressure or distortion in stimuli.

Thermoreceptors

Respond to changes in temperature, affecting body reactions.

Nociceptors

Detect pain from cellular damage or injury.

Photoreceptors

Sense electromagnetic radiation, including light wavelengths.

Rods

Photoreceptors for low light vision in the retina.

Cones

Photoreceptors for color vision and detail perception.

Olfaction

Sense of smell, converting chemical signals to neural signals.

Olfactory Bulb

Brain structure processing signals from olfactory receptors.

Chemoreceptors

Detect chemical stimuli, including various types and shapes.

Taste

Sense involving five basic flavors: sweet, sour, salty, bitter, umami.

Glomerulus

Structure in the olfactory bulb for signal processing.

Cilia

Hair-like structures increasing surface area for olfactory detection.

Colorblindness

Mutation affecting the ability to perceive certain colors.

Sensitivity

Depends on the number of receptor cells present.

ATP

Molecule that binds to receptors, signaling cellular damage.
