- What is the function of the sclera?
- The sclera is the outer covering (whites) of the eyes
- What is the function of the cornea?
- The cornea is a transparent, more convex anteriormost portion of the sclera
- What is the function of the schleral venous sinus?
- reabsorbs aqueous humor (around cornea)
- What is the function of the choroid?
- layer covering the retina that contains blood vessels and veins
- What is the function of the iris?
- colored part of the eye, adjusts the amount of light let in
- What is the function of the pupil?
- hole in the iris that lets in light
- what is the function of the lense?
- The lense is a hard, clear biconvex structure immediately behind the pupil and iris, that bends the light so that it is projected onto the rods and cones
- What is the function of the suspensory ligament?
- a halo of delicate fibers attaching the lense of the ciliary body
- what is the function of the ciliary body?
- black pigmented body that appears to be halo encircling the lense, maintains intraocular pressure
- what is the function of the retina?
- delicate white membrane overlying the darkly pigminted choroid coat; innermost layer of eyeball around vitreous humor
- What is the function of the macua lutea and fovea centralis?
- The macula lutea is the yellow spot, area of high cone density centered at the fovea centralis, which is the area of greatest visual acuity.
- What is the optic disk?
- blind spot
- What is the function of the vitreous humor?
- thick fluid inside the eyeball
- What is the function of the aqueous humor?
- clear watery fluid between lense and cornea
- What is the function of the optic nerve?
- innervates the eye
- What is the conus medullaris?
- cone-shaped inferior terminal of the spinal cord
- What are the major nerves of the brachial plexus?
- Axillary nerve, musculocutaneus nerve, radial nerve, ulnar nerve
