How many chemicals do we detect with smell?
|
6-50
|
|
|
Starts at the top of the nasal cavity along the septum, starts out as bipolar neurons (at ends of neurons are receptors), Axons form first cranial nerve through cribiform plate to olfactory bulb to temporal lobe. Mucus lines it.
|
smell
|
|
|
Gustatory cells inside taste pore are ..., the support cells of the taste pore are ...
|
bipolar, modified simple columnar.
|
|
|
... at tip of tongue, then ..., then ...then ... towards back.
|
sweet, salt, sour, bitter
|
|
|
tears have ...which are enzymes that destroy infection.
|
lysomes.
|
|
|
...produces tears.
|
lacrimal gland
|
|
|
outer layer of the eye, consists of sclera, cornea and conjunctiva
|
fibrous tunic
|
|
|
covers exposed part of sclera, cornea and inside of eye lid
|
conjunctiva
|
|
|
vontrols amount of light that enters the eye, consists of choroid, and iris
|
vascular tunic
|
|
|
in eyeball, provides nutrients and takes away waste
|
choroid
|
|
|
controls amount of light that enters the eye. made of smooth muscle and ciliary body and conn. tissue. radials. pigmented epithelium absorbs light.
|
Iris
|
|
|
...of iris causes accomidation of lens. tendons to lens, smooth muscle. changes shape of lens, allows it to focus on far and close objects. secretory.
|
ciliary body
|
|
|
group of modified capilaries that secretes auqeos humor.
|
Secretory-
|
|
|
aequeos humor is mostly...
|
blood plasma
|
|
|
layer of eyeball (retina) where photoreceptor, bipolar layer and ganglia layer is
|
nervous tunic
|
|
|
photorecptor area is next to the ...layer
|
pigmented layer
|
|
|
rods and cones are in the ...layer. rods are specialized for vision in...light, where you see shapes, movement, shades of gray.
|
photoreceptor layer, dim
|
|
|
inside rods is a protein called..., which means...
|
rhodophoson, visual purple.
|
|
|
when light enters,...breaks down in to smaller chemicals, called..., causing a nerve impulse, only functions in dim light. in full light, cycle stops.
|
rhodophoson, scotopsin and retinine
|
|
|
about 3 million found in fovea centrallis, function in bright light, gives sharpness of vision, allows you to see color, each one has a different pigment that acts like rhodophoson.
|
cones
|
|
|
Found in cones, Erythrolabe, cyanolabe, chorolabe are which colors?
|
Erythrolabe is red, cyanolabe is blue, chorolabe is green. Eyes will only detect these colors.
|
|
|
When light hits the pigments in cones, it broken down then reformed by...
|
ATP
|
|
|
Synaptic region in the retina composed of bipolar neurons.
|
Bipolar layer
|
|
|
Layer in the retina that recieves info from the bipolar layer
|
ganglia layer
|
|
|
several bipolars feed into one...
|
ganglia
|
|
|
all axons of ganglionic neurons focus on one point called...
|
the optic disk
|
|
|
...is the beginning of the optic nerve, where they all form together at. no rods or cones there.
|
optic disk
|
|
|
...corrects light by bend and focus that is bent by the cornea.
|
lens
|
|
|
...in anterior cavity of eye produced by ciliary body - secretory portion. Its modified blood plasma that continually being produced. goes out of canals of schlemm and mixes with tears, helps circulate nutrients and remove waste.
|
aeqeous humor
|
|
|
helps develope intraocular pressure, its the culprit to glocoma, because of too much pressure
|
aeqeous humor
|
|
|
posterior cavity of eye filled with.....it allows light to pass through and maintains roundness of eye by intraocular pressure. its transparant and protein bases. once eye is formed no more is produced, if you lose it eye wont function
|
vitreous humor
|
|
|
...controls pupil, smooth muscles radiating out and circling around it, which controls amount of light going into the eye.
|
iris
|
|
|
pigmented epithelium associatted with choroid, dense layer made of epithial tissue. pigment comes from...which is produced by ...function is to absorb whatever light isnt absorbed by retina.
|
melanocytes, melanin
|
