Sits in a protective bony socket/bony cavity called the orbit which is located in the skull at the junction of the bones of the cranium and the nose
Found within the orbit are structures like the eyeball, extraocular muscles, nerves, blood vessels and the lacrimalapparatus (gland and the duct that drain tears)
Has a circular band of involuntary muscle whose contraction causes the relaxation of the suspensory ligaments and its relaxation tightens the suspensory apparatus
Transparent, biconvex body suspended from the ciliary body by the suspensory ligament
Anterior surface is related to the iris and the posterior surface lies on the depression formed by the vitreous body
Enclosed by a transparent elastic membrane known as the lens capsule
The convexity of the surfaces of the lens vary due to the tension created by the suspensory ligaments therefore changing the focal length to accommodate near or far vision
Pull from the direction of the medial or nasal wall of the orbit
Dorsal oblique muscle originates from the orbital apex and takes an oblique position by passing through the trochlea on the medial orbital wall
Ventral oblique muscle is a thin narrow muscle located along the anterior margin of the floor of the orbit, originates from the medial wall of the orbit to insert on the lateral surface of the eye
