What ligament runs from the body of C2 to occiput?
What ligament runs from the sides of the dens to the occiput?
alar, aka check ligament
What is the function of the alar ligament?
Where does the apical dental ligament run?
from the tip of the dens to the rim of the occiput
What is the function of the denticulate ligament?
anchors the spinal cord to the bony vertebral canal
What ligaments can affect the IVF?
ligamentum flavum and the posterior longitudinal ligament
What are the special senses?
taste, smell, sight, and hearing
What are the taste papillae?
circumvallate, fungiform, and foliate
What papillae have no taste function?
What taste bud is the largest and fewest?
What do circumvallate papillae taste?
What is the arrangement of circumvallate papillae on the tongue
8-12 in a V shape
What is the most numerous taste bud?
What taste buds are found on the posterior roof and lateral margins of the mouth?
What is the innervation path for taste in the anterior 2/3 of the tongue?
CN VII -> chorda tympani -> pterygopalatine ->solitary tract and nucleus
What does the anterior 2/3 of the tongue taste?
sweet, sour, and salty

What does the retina develop from?
What does the sclera develop from?
What is included in retinal cells?
amacrine, bipolar, ganglion, horizontal, pigments, rods and cones
What is the nerve path for vision?
retina -> optic nerve -> optic chiasm -> optic tract (connects superior colliculus) -> lateral geniculate nucleus -> optic radiations -> calcarine fissure of the occipital lobe
What is the fovea centralis?
center of the macula lutea, provides greatest visual acuity
What is found in the fovea centralis?
What is the "blind spot" where the optic nerve and vessels attach to the eye?
What does the ciliary muscle control?
What is the nerve pathway for the auditory pathway?
spiral ganglion -> cohlear nerve -> ventral -> dorsal cochlear nucleus -> lateral lemniscus -> inferior colliculus -> medial geniculate -> temporal lobe
What is the sound pathway?
external auditory meatus -> tympanic membrane -> handle of malleus -> incus -> stapes -> oval window -> cochlea -> round window
What do the semicircular canals monitor?
angular acceleration and deceleration
What do the utricle and saccule monitor?
What runs from the middle ear to the nasopharyngeal area?
