Receptors I
Dendrites that detect temperature changes.
What are thermoreceptors?
This happens when receptors convert the sensory stimulus into an electrical impulse.
What is transduction?
Three "types" of pain sensation, and corresponding tissues.
What are superficial pain (skin and subcutaneous tissues), deep pain (muscle, joints, bones), and visceral pain (internal organs).
Sense of smell.
What is olfaction?
Sense of taste.
What is gustation?
Another name for pain receptors.
What are nociceptors?
How much of the sensation the animal is consciously aware of.
What is perception?
Receptor responsible for detecting heat and cold in the skin.
What are superficial thermoreceptors?
Sense organ for smell.
What is olfactory epithelium?
The five primary tastes.
What are sweet, sour, salty, bitter, and umami?
Dendrites or cells that detect concentration of specific chemicals.
What are chemoreceptors?
Modulation.
What occurs when neurons in the sensory pathway can be excited or inhibited?
Receptors responsible for detecting core body temperature and reflexes they control.
What are central thermoreceptors and sweating, shivering, piloerection, and thyroid function.
Three types of cells relating to olfaction and their purpose.
What are olfactory receptors - first order neurons, supporting cells - support and protect olfactory receptors, and basal stem cells - divide and differentiate to produce new receptors?
Sense organs for taste on papillae of tongue.
What are taste buds?
Cells that detect electromagnetic stimuli.
What are photoreceptors?
Dendrites stimulated mainly by chemicals released by tissue damage or inflammation.
What are pain receptors or nociceptors?
Mechanoreceptors in muscles, tendons, and joints that monitor location of body parts.
What is proprioception?
Olfactory glands (aka bowman's glands).
What are glands that secrete mucus on the surface that dissolves odorant molecules?
Two types of cells relating to taste and their purpose.
What are gustatory cells - sensory receptors, and supporting cells - support and protect gustatory cells.
Dendrites or cells that detect mechanical distortions of cell membranes caused by touch or pressure, stretch or bend, or vibrations.
What are mechanoreceptors?
Sensory pathway relays sensation to central nervous system.
What is transmission?
Three specific types of mechanoreceptors and the tactile sensations they detect.
What are Meisnner's corpuscles - fine touch, hair root plexuses - movements of hairs, and Pacinian corpuscles - deep pressure.
Specialized olfactory organ within incisive bones of some species that detects pheromones.
What is the vomeronasal organ?
Long microvilli with receptors and the openings in papilla.
What are taste hairs and taste pores?
