Physiology And Anatomy Of The Eye

Last week we discussed vision from a historical perspective in order to understand how johannes kepler rené descartes and bishop berkeley discovered the importance of the mind in effecting vision. The bony orbit is a cavity comprising parts of the lacrimal bone includes fossa for nasolacrimal duct and the maxilla includes caudal foramen of infraorbital canal.

Physiology and anatomy of the eye. Conjunctiva cornea iris lens macula retina optic nerve vitreous and extraocular muscles. Anatomy physiology pathology of the human eye included are descriptions functions and problems of the major structures of the human eye. The eye is surrounded by the orbital bones and is cushioned by pads of fat within the orbital socket.

Extraocular muscles help move the eye in different directions. It is a complex optical system which collects light and converts it to electrochemical impulses in neurons. The vitreous humor helps the eye hold its spherical shape.

Development anatomy and physiology of the eye the word perspective comes from the latin per through and specere look at. It is continuous with the temporal bone and the pterygopalatine fossa caudally. Anatomy of the eye.

The eye is contained within the bony orbit of the head. Nerve signals that contain visual information are transmitted through the optic nerve to the brain. The eye is made up of a outer fibrous layer a middle vascular layer and an inner retinal layer where sensory information is received then delivered to the visual cortex for processing.

Finally the light rays land and come to a sharp focusing point on the retina. In a normal eyeball after exiting the back of the lens the light rays pass through the vitreous a clear jelly like substance that fills the globe of the eyeball.
