, BIO 253 HONDROS TEST 2- 2023 QUESTIONS AND
ANSWERS |GRADED A+
Sound transmission in ear - Answer- Pinna (auricle)--external auditory canal--tympanic
membrane (vibrates back and forth; pushes on the ossicles)--malleolus, incus, stapes--
fluid in the inner ear becomes wavy and stimulates mechanoreceptors (hair cells) in the
cochlea
Which receptors never experience adaptation? - Answer- Nociceptors--Pain
Receptors controlled by being stretched or pushed on - Answer- Mechanoreceptors
Ie-Bladder distention
The receptor of the nose - Answer- chemoreceptors
Which structure contains tracts that carry nerve impulses to/from brain? - Answer- White
matter
Endocrine glands - Answer-
ductless
