General senses of touch |
|
|
|
smell, taste, sight, hearing, equilibrium |
5 senses: |
|
|
|
Lacrimal gland |
Produces lacrimal fluid |
|
|
|
Lacrimal canals |
drain lacrimal fluid from eyes |
|
|
|
Lacrimal sac |
provides passage passage of lacrimal fluid towards nasal cavity |
|
|
|
Nasolacrimal duct |
empties lacrimal fluid into nasal cavity |
|
|
|
lacrimal fluid |
water & salt (tears); antibodies & lysosomes |
|
|
|
fibrous, vascular, semsory |
3 layers of the eye: |
|
|
|
Cornea & sclera |
structures of the fibrous layer |
|
|
|
Sclera |
seen anteriorly as the “white” of the eye; connective tissue |
|
|
|
Cornea |
only human tissue that can be transplanted w/o fear of rejection; allows for light to pass through the eye; transparent |
|
|
|
Choroid |
blood-rich nutritive later in the posterior of the eye |
|
|
|
Ciliary body |
smooth muscle attached to lens |
|
|
|
Iris |
regulates amount of light entering eye; pigmented & gives the eye it’s color |
|
|
|
Pupil |
rounded opening in the iris |
|
|
|
rods & cones |
2 types of photoreceptors: |
|
|
|
Rods |
photoreceptors Found toward the edges of the retina; allow dim light vision & peripheral vision; all perception is in gray tones |
|
|
|
cones |
photoreceptors that allow for detailed color vision; densest in the center of the retina |
|
|
|
Fovea centralis |
area of the retina w/only cones |
|
|
|
optic disk (blind spot) |
place where there are no photoreceptors present |
|
|
|
the absence of a specific cone type |
color blindness is caused by... |
|
|
|
Lens |
biconvex crystal-like structure; held in place by suspensory ligament |
|
|
|
Cataracts |
condition where the lens becomes hard and opaque w/ age; vision is hazy & distorted |
|
|
|
Aqueous humor |
watery fluid between lens & cornea; provides nutrients for the lens & cornea |
|
|
|
Vitreous humor |
posterior to the lens; gel-like substance that prevents the eye from collapsing; helps maintain intraocular pressure |
|
|
|
hearing & equilibrium |
2 senses housed by the ears: |
|
|
|
Mechanoreceptors |
receptor cells of the ear: |
|
|
|
External (outer) ear, middle (tympanic) ear, inner ear (bony labyrinth) |
3 areas of the ear: |
|
|
|
external ear |
area of the ear Involved w/hearing only |
|
|
|
auricle, external acoustic meatus |
Structures of the external ear: |
|
|
|
external acoustic meatus |
“ear canal”; marrow chainbee in the temporal bone; lined w/skin & ceruminous (wax) glands; ends at the ear drum |
|
|
|
middle ear (tympanic cavity) |
air filled cavity w/in the temporal bone; only involved in hearing |
|
|
|
malleus (hammer), incus (anvil), stapes (stirrup) |
bones (ossicles) of the middle ear: |
|
|
|
Inner ear (bony labyrinth) |
includes sense organs for hearing & balance; filled w/perilymph; maze of bony chainbers w/in the temporal bone |
|
|
|
cochlea, vestibule, semicircular canals |
Structures of the inner ear/bony labyrinth: |
|
|
|
inner ear |
Equilibrium receptors are found in the... |
|
|
|
Vestibular apparatus |
Equilibrium receptors are called... |
|
|
|
static equilibrium & dynamic equilibrium |
2 functional parts of the vestibular apparatus: |
|
|
|
Maculae |
receptors in the vestibule; send info via the vestibular nerve; report on the position of the head |
|
|
|
Otoliths |
tiny stones that float around in gel around the hair cells |
anatomy of the Maculae |
|
|
Crista ampullaris |
receptors in the semicircular canals |
|
|
|
soft palate, cheeks, mostly tongue |
location of the taste buds: |

|
|
Roof of the nasal cavity |
olfactory receptors are located on... |
|
|
|
cortex |
Interpretation of smells is made in what region of the brain? |
|
|
|
sides of papilae |
tastebuds are found on... |
|
|
|
filiform papilae |
sharp papillae w/no taste buds |
|
|
|
Fungiform papillae |
rounded papillae w/ taste buds |
|
|
|
Circumvallate papillae |
large papillae w/ taste buds |
|
|
|
