|
Term
|
Definition
right and left white matter between 2 dorsal and ventral roots |
|
|
Term

|
|
Term
|
Definition
whitish colored in life; part of the eye to which the extrinsic eye muscles are attached; hard |
|
|
Term
|
Definition
front part of the eye; clear in life |
|
|
Term
|
Definition
sclera and cornea combined; maintains the general shape of the eye |
|
|
Term
|
Definition
middle, dark layer of the eye; highly pigmented and rich in blood vessels; povides proper nutrition to the retina |
|
|
Term
|
Definition
posterior portion of the vascular tunic; dark and extensive |
|
|
Term
|
Definition
represents an anterior portion of the vascular tunic; also receives contributions from the pigmented retina |
|
|
Term
|
Definition
hole in the middle of the iris |
|
|
Term
|
Definition
represents the anterior portion of the vascular tunic; also receives contributions from the pigmented retina; contains intrinsic ciliary muscles; pleated in appearance when viewed from behind; controls lens shape |
|
|
Term
|
Definition
portion of the anterior vascular tunic; suspends the lens |
|
|
Term
|
Definition
innermost layer of the eye; the visual receptor or nervous portion of the eye |
|
|
Term
|
Definition
innermost layer of the eye; mainly composed of the retina |
|
|
Term
|
Definition
portion of the retina with the highest accuity; has many cones for color vision |
|
|
Term
|
Definition
lacks rods and cones; place where the optic nerve leaves the eye |
|
|
Term
|
Definition
clear structure which focuses the light entering the eye |
|
|
Term
|
Definition
large; would normally be filled with jelly-like vitreous humor |
|
|
Term
|
Definition
would normally be filled with aqueous humor; 2 divisions: anterior chamber and posterior chamber |
|
|
Term
|
Definition
poriton of the anterior cavity in front of the iris |
|
|
Term
|
Definition
very small portion of the anterior cavity between the lens and the iris |
|
|
Term
|
Definition
2nd cranial nerve which passes sensory information from the eye to the brain |
|
|
Term
|
Definition
tiny hole at the junction of the cornea and the sclera for drainage of aqueous humor from the anterior cavity |
|
|
Term
|
Definition
iridescent portion of the choroid; reflects some light passing through the retina back onto the rods and cones hence facilitates animals seeing in dim light; man does not have this structure |
|
|
Term
|
Definition
outer layer of the retina; dark; would be adjacent to the choroid portion of the eye |
|
|
Term
|
Definition
neurons which specifically respond to light; rods and cones |
|
|
Term
|
Definition
a layer of neurons found interior to rods and cones |
|
|
Term
|
Definition
innermost layer of neurons in the retina of the eye; these would not be in contact with the posterior cavity in the intact eye; axons of these neurons converge to form the optic nerve |
|
|
Term
|
Definition
when a bright light is in a person's eye, the pupil constricts; when the light is removed, it dilates |
|
|
Term
|
Definition
the pupil will constrict when viewing a near object and dilate when viewing a far object |
|
|
Term
|
Definition
the eyeballs will converge when viewing a near object |
