Video Summary

The eye and ear are both organs of the body that are responsible for receiving sensory information. The eye is responsible for receiving visual information, while the ear is responsible for receiving auditory information.

The eye structures include the eyelashes, lids, muscles, accessory glands, and conjunctiva, and internal structures which include sclera and cornea, the uvea which is the vascular layer in the middle, subdivided into the iris, ciliary body, and choroid; and finally, the retina that consists of nervous tissue.

The ear has three main parts, which are the outer ear, middle ear, and inner ear. The outer ear consists of the auricle, and the external auditory canal and are both lined by keratinized stratified squamous epithelium. The middle ear extends from the tympanic membrane to the oval window of the inner ear, and it is lined with non-keratinized stratified squamous epithelium. Finally, the inner ear consists of the cochlea, semicircular canals and the vestibule.
