Six extraocular muscles in the orbit are attached to the eye. This helps to protect our eyes from injury.

It is enclosed within the eye sockets in the skull and is anchored down by muscles within the sockets.

Eye socket anatomy diagram. In addition to the eyeball itself the orbit contains the muscles that move the eye blood vessels and nerves. The gray line which is the muscle of Riolan the most superficial aspect of the orbicularis muscle is also shown. The extraocular muscles are placed in the orbit but are extrinsic and separate from the eyeball itself.

Just behind the iris. Eyeball Bulbus oculi The eye is a highly specialized sensory organ located within the bony orbitThe main function of the eye is to detect the visual stimuli photoreception and to convey the gathered information to the brain via the optic nerve CN IIIn the brain the information from the eye is processed and ultimately translated into an image. The retina senses light and creates impulses that are sent through the optic nerve to the brain.

Diagram of the orbit eyeball socket in the skull. The back part of the eyes interior. 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.

Through a process called accommodation this lens helps the eye automatically focus on near and approaching objects like an autofocus camera lens. They enclose the eyeball and its associated structures. At the front of the eye is a clear round window called the cornea.

The orbit is the bony eye socket of the skull. Our eyeballs are fairly round organs cushioned by fatty tissues and they sit in two bony sockets inside the skull. It is made up of four facial bones and three cranial bones.

The white of your eye. These muscles control to move the eye from side to side up down and rotate the eye. Anatomy of the Eye Category.

This is a strong layer of tissue that covers nearly the entire surface of the eyeball. As we journey through the different structures refer to the diagrams to quickly digest the content on this page.

A thin layer of tissue that covers the entire front of your eye except for the cornea. Anatomically the eye comprises two components fused into one. Hence it does not possess a perfect spherical shape.

The orbit is formed by the cheekbone the forehead the temple and the side of the nose. May 2019 The eye socket is a bony cup that surrounds and protects the eye. Each eye is a liquid-filled ball 25 cm in diameter.

Diagram of Human Eye with Labelling. These muscles move the eye up and down side to side and rotate the eye. The eye is rather like a living Camera.

The diagrams below show cross sections of the human eyeball. Diagram of eye with surrounding superior oblique medial and inferior rectus muscles. It is shaped similar to a pyramid with the base facing anteriorly front and the apex pointing posteromedially to the back and inner side.

External components include structures which can be seen on the exterior of the eye and internal components include structures present within. Behind the cornea is a lens. The orbit is the bony hollow region in the skull that houses the eyeball and is also referred to as the socket.

Parts of the Eye Outside the Eyeball. The eye sits in a protective bony socket called the orbit. Maxilla zygomatic bone lacrimal bone palatine bone frontal bone ethmoid bone and sphenoid bone.

Thus the floor of the orbit is made up of parts of the maxilla zygomatic and palatine bones while the roof is made up of the orbital plate of the frontal bone and behind this by the lesser wing of the sphenoid. This diagram demonstrates the conceptual split between the anterior lamella skin and orbicularis right side and posterior lamella tarsus and conjunctiva left side of the eyelid. Here is a complete diagram showing the anatomy of the eye minus the technical name for the human eye socket the orbit.

The eye is cushioned within the orbit by pads of fat. 2015 WebMD LLC. Once the retina converts the light into nerve signals these are sent through the optic nerve at the back of the eye to the brain.

Light focused by the cornea and crystalline lens and limited by the iris and pupil then reaches the retina the light-sensitive inner lining of the back of the eye. There are seven extraocular eye muscles that are present in the eye socket that join the eye to move it. A fracture is a broken bone in the eye socket involving the rim the floor or both.

In anatomy the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. The extraocular muscles are attached to the white part of the eye called the sclera. They enclose the eyeball and its associated structures.

The rim of the socket is made of fairly thick bones while the floor and nasal side of the socket is paper thin in many places. Supraorbital foramen shown above the eye and inferior orbital fissure inferolaterally. The light-sensitive nerve layer that lines the inside of the back of the eye.

This article explores the anatomy of the eye looking at the different structures of the human eye and their function. The bony orbits or eye sockets are bilateral and symmetrical cavities in the head. The orbit appears as a quadrangular pyramidal cavern in the upper face.

Note that this is just anterior to the meibomian gland orifces which come from the tarsus. The human eye is a roughly spherical organ responsible for perceiving visual stimuli. The opening in the middle of the iris through which light passes to the back of the eye.

Eye Anatomy Complete Physiology of Eye is described below in the given paragraph. In this article we shall look at the borders contents and clinical correlations of the bony orbit.
