|
Definition
| white matter between the two dorsal horns of gray matter |
|
|
Term
|
Definition

|
|
Term
| ventral (anterior) funiculi |
|
Definition
| white matter between the 2 ventral and anterior roots |
|
|
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 |
