Anatomy and Physiology 101 Final Exam Ivy Tech 2026

Anatomy and Physiology 101 Final Exam Ivy Tech 

179.  Meissners corpusles: detect fine touch

180.  Pacinian corpuscles: detect heavy pressure and vibrations in joints

181.  warm receptors: sensitive to temp above 25C unresponsive to temp 45C

182.  cold receptors: sensitive to temp 10-20C

183.  muscle spindles: sensory receptors within the belly of a muscle that primarily detect changes in the length of this muscl

184.  golgi tendon organs: senses changes in muscle tension

185.  describe olfactory sensations: olfactory nerves --> olfacotry bulbs --> olfactory tracts --> limbic system and olfactory cortex

186.  describe taste sensations: impulse form taste receptors --> cranial nerve VII,

IX,X --> medulla oblongata --> thalamus --> gustatory cortex

192 parts of outer ear: auricle external acoustic meatus tympanic membrane

193.  parts of middle ear: tympanic cavity auditory canal oval window

ossicles - mallus, incus, stapes

194.  parts of inner ear: osseous labyrinth

membranous labyrinth chochlea semicircular canals vestibule

195.  How are sound vibrations transmitted to the inner ear: Sounds are channeled into the outer ear, they vibrate the eardrum, which moves the bones of the middle ear (the hammer, anvil and stirrup) which vibrates the outer edge of the cochlea, which send vibration waves to the hairs in the fluid filled inner ear, which sends neuron signals to the brain, which interprets the signals and creates what we recognize as sounds. The fluid gives oxygen to the inner ear as the pulse of the blood vessels would deafen us.

196.  how to hearing receptors work: the hearing receptors are also known as hair cells. The hair cells are not real hairs but are cells with 100 or so projections sticking out that bend in response to movements of the basilar membrane

197.  static equilibrium: vestibule, senses position of head when body is not moving 198. dynamic equilibrium: semicircular canals, senses rotation and movement of head and body

199.  what are rods: provide vision in dimlight, colorless vision,, outline of images

200.  what are cones: provide vision in bright light, color vision, sharp images

201.  what are the parts of the eye?: retina cornea

iris

lens sclera choroid coat
