General Senses (anatomy)

What is transduction and what do we call cells that carry out this process?

-Changing of a physical stimulus to an action potential in a nerve

-Carried out by rods and cones

What is the difference between a sensation and a perception?

-Sensation: The arriving into from these senses

-Perception: Interpretation and conscious awareness of a sensation

Nociceptors

-Stimulated by pain

Mechanoreceptors

-Stimulated by distortion

Chemoreceptors

-Stimulated by chemical detection

Thermoreceptors

-Stimulated by temperature

Proprioceptors

-Stimulated by position

Baroreceptors

-Stimulated by pressure

Give an example of a chemoreceptor and explain what it does

-Found in Carotid artery

-Monitors pH, carbon dioxide and oxygen levels

What is adaptation to a sensory stimulus

-Reduction in sensitivity of a constant stimulus

what is the difference between a baroreceptor and a proprioceptor?

Baroreceptors: Never detect changes in arterial blood pressure

Proprioceptors: Sensory receptors

Examples of general senses (receptors everywhere)

pain, touch pressure, temperature, proprioception etc.

Examples of special senses (receptors in specific place)

smell (olfaction), taste (gustation), vision, hearing, equilibrium etc.
