embryonic origin of the lens of the eye
this layer includes the choroid, stroma ciliary body, and the iris
this layer of squamous epithelial cells provides for metabolic exchange between the cornea and the aqueous humor
this layer includes the sclera and cornea
watery liquid located in the anterior and posterior chambers of the eye
this fluid of the inner ear is high in Na concentration and low in K concentration
inner layer of retina that contains light sensitive receptors and complex neuronal networks
sensory innervation of the corneal epithelium

embryonic origin of the sclera
Effect of age on lens’s elasticity and ability to accommodate
pigment associated with rods
contains the nuclei or cell bodies of horizontal, amacrine, bipolar, and Muller's cells
conversion of sound waves to mechanical vibrations is the main function of which part of the ear?
an outer layer of retina that is composed of simple cuboidal melanin containingcell
inflammation of eardrum
embryonic origin of the incus
which auditory ossicle is attached to the eardrum
this structure is composed of dense fibrous connective tissue that provides attachment sites for the extrinsic eye muscles
central circular aperture of the iris
