Cranial nerves II III IV V and VI Vasculature. The following bones take part in their formation. 5 the upper jaw maxillary bone.

Light enters our eyes through the pupil then passes through a lens and the fluid-filled vitreous. The eye is protected from mechanical injury by being enclosed in a socket or orbit which is made up of portions of several of the bones of the skull to form a four-sided pyramid the apex of which points back into the head. In anatomy the orbit is the cavity or socket of the skull in which the eye and its appendages are situated.

Medial wall Formed by the ethmoid maxilla lacrimal and sphenoid bones. The lacrimal bones are small flat craniofacial bones located in the eye socket. Apex Located at the opening to the optic canal the optic foramen.

For ophthalmologists optometrists medical dental and optometry students eye-anatomy forms the basis for eye-pathology in diseases. Maxilla and zygomatic bone. The zygomatic bones join with several other bones of the face including the nose jaw portions of the eye and bones just in front of the ears.

In humans seven bones make up the bony orbit. The optic canal at the orbital apex connects the orbital cavity to the middle cranial fossa.

1 the small thin lacrimal bone that sits in the inner eye. In addition to the eyeball itself the orbit contains the muscles that move the eye blood vessels and nerves. We are pleased to provide you with the picture named Anatomy Of The Eye And Bones Of The Orbit.
