Transparent anterior portion
Allows light into the eye and participates in the focusing of light onto the back of the eye.
Sclera
White of the eye. Tough protective covering for most of the eyeball
Uvea
Middle layer of eye.
Consists of choroid, ciliary body, and iris.
Choroid
Inner lining of the sclera. Contains blood vessels to nourish the eye.
Ciliary body
Lies at the anterior edges of the choroid body and consists of ciliary muscles and the ciliary process.
Ciliary muscles
Adjust the shape of the lens for focusing
Ciliary process
Produces a watery substance called aqueous humor which bathes the anterior region of the eye
Iris
Circular colored portion of the eye.
Pupil
Regulates the amount of light that enters the eye. In bright light muscles constrict the pupil. In dim light they relax. Radial muscles dilate the pupil when a person is stressed or excited.
Retina
Inner layer of the eye.
Several layers of nervous tissue containing cones and rods, which are the cells that transform light into nerve impulses.
Fovea centralis
Cones responsible for central and bright light vision are concentrated here. Located in a small yellowish area called the macula lutea
Optic disc or blind spot
Small area of the retina w no cones or rods and does not produce any visual images. Point at which the optic nerve begins and the entry point for the major blood vessels of the eye.
Lens
Not considered one of the layers of the eye. Posterior to the iris and held in place by suspensory ligaments.
Refraction
As light passes through the lens it is bent.
Lens accommodation
Ciliary muscles change the shape of lens to allow clear vision of near and far objects
Anterior cavity
Contains aqueous humor
Posterior cavity
Contains vitreous humor
Outer eye consists of
Orbital cavity, extrinsic ocular muscles
Eyelids, conjunctival membrane
Lacrimona all apparatus
6 extrinsic ocular muscles
Superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, inferior oblique.
Lacrimal glands
Produce tears delivered to the eye by the lacrimal ducts. Small openings called punctae drain tears from the eyes into the nose.
Ear consists of
External ear
Middle ear
Inner ear
Responsible for hearing and plays a prominent role in maintaining balance
External ear is composed of
Auricle
External auditory meatus
Eardrum (tympanic membrane)
Middle ear
Three ossicles called
Malleus-hammer
Incus-anvil
Stapes-stirrup
Inner ear contains
Bony labyrinth (vestibule, semicircular canals, and cochlea) Membranous labyrinth (utricle, saccule, semicircular ducts, and cochlear ducts)
Sound is transmitted
By the vibration of the stapes against the oval window, causing hair cells in the organ of Corti to sway and stimulate the underlying nerve fibers that create nerve impulses which travel to the temporal lobe of the brain
