Vision/the eye
This % of all sensory receptors is located in the eye.
70%
Name the 3 ossicles in order.
Malleus, incus, stapes
Both smell and taste use this type of receptor.
Chemoreceptor
Where are olfactory receptors located?
On the roof of the nasal cavity
This condition results from unequal pull of the eye muscles in babies.
Strabismus
Name 3 of the 4 accessory structures that protect and support the eye.
Eyelids, eyelashes, conjunctiva, lacrimal apparatus
This structure contains the organ of Corti.
Cochlea (the snail!!)
These papillae contain NO taste buds.
Filiform papillae
What dissolves chemicals in the nose for detection?
Mucus
Clouding of the lens that causes hazy vision is called this.
Cataract
This structure can be transplanted without fear of rejection because it is avascular.
These receptors in the vestibule detect static equilibrium.
Maculae
Name the 4 basic taste sensations.
Sweet, sour, salty, bitter
What cranial nerves helps detect scent.
Olfactory nerve
This occurs when the ossicles fuse together.
Otosclerosis
These photoreceptors are mostly in the peripheral retina and help with dim-light vision.
Rods
This receptor in the semicircular canals detects rotational movement.
Crista ampularis
Why is bitter taste important for survival?
It helps detect toxins or spoiled food
What structure(s) in the nose act like seaweed floating in the water catching passing particles.
Cilia
Why does food lose flavor during a severe cold?
Smell is impaired, and taste and smell work together to keep flavor
Trace the pathway of tears from production to the nasal cavity (4 to 5 different steps).
Lacrimal gland --> lacrimal canaliculi --> lacrimal sac --> nasolacrimal duct --> nasal cavity
Why do you feel dizzy after spinning and stopping?
Endolymph keeps moving and bends the cupula/hair cells even after movement stops
Where on the papillae are taste buds found (on the papillae that actually contain taste buds).
The sides of the papillae
What region of the brain interprets smell?
Increased intraocular pressure caused by poor drainage of aqueous humor describes this disorder.
Glaucoma
