Human Eye Socket Anatomy

In this activity students will dissect the human head and eye to investigate the anatomy and physiology of the human eye. These muscles move the eye up and down side to side and rotate the eye.

Although much of the socket encloses the eye some of it protrudes beyond and can be readily felt behind the eyebrow.

Human eye socket anatomy. For those who were searching the technical name for the human eye socket is the orbit. Eye - Horizontal Section A human eyeball showing the following structures. Anatomy of the human eye.

This is the part that identifies a persons eye colour. Parts of the Eye Outside the Eyeball. This is a strong layer of tissue that covers nearly the entire surface of the eyeball.

Anatomy of the human eye. The secreted tears are collected on the conjunctiva of your upper eyelid. The human eye is a paired sense organ that reacts to light and allows vision.

The eye is part of the sensory nervous system. In our body the Orbits are conical or four-sided pyramidal cavities which open into the midline of the face and point back into the. What does it do.

The human eye consists of the eyeball optic nerve orbit and appendages eyelids extraocular muscles and lacrimal glands. This is the bony cavity that the eyeball sits in with all its associated muscles blood vessels and nerves. On the outside of the eye you have the eyelid and the eye lashes.

In anatomy the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. Eye Sockets Orbits On each side of our bodys head the Orbit Eye Socket is a facial bone cavity socket of the skull in which the eye and its appendages are situated. The eye is cushioned within the orbit by pads of fat.

Light projects through your pupil and. Eye sockets are cavities that essentially cup the eyes. Several skull bones make up a socket and these bones join to form a four-walled pyramid behind each eye.

In addition to the eyeball itself the orbit contains the muscles that move the eye blood vessels and nerves. Rod and cone cells in the retina are photoreceptive cells which are able to detect visible light and convey this information to the brainEyes signal information which is used by the brain to elicit the perception of color shape depth movement and other features. Orbit may refer to the bony socket.

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. Six extraocular muscles in the orbit are attached to the eye. The iris contains circular muscles which go around the pupil and radial muscles that radiate toward the pupil.

Most of the eye is filled with a clear gel called the vitreous. Eyelashes and eyelids help to shield the eye from potential damage. Just behind the iris and pupil lies the lens which helps focus light on the back of your eye.

Socket represents the preop sac. The human eye is a highly evolved structure of our anatomy and has many coexisting and interdependent elements. In the adult human the volume of the orbit is 30 millilitres of which the eye occupies 65 ml.

Vitreous body Optic disc Fovea of optic disc Lamina cribrosa of sclera Optic. The eye sits in a protective bony socket called the orbit. Structures such as the lacrimal gland the optic nerve and muscles keep the eye and the socket functioning properly.

The orbit is the bony eye socket of the skull. The iris is a flat thin ring-shaped structure sticking in to the anterior chamber. Orbit can refer to the bony socket or it can also be used to imply the contents.

Human Anatomy - Eye Socket 1 Human Anatomy - Eye Socket Lesson Overview Humans have five different senses through which to gather information about their surroundings. It is capable of moving and follow the objects along with accommodating to near and far. The orbit is formed by the cheekbone the forehead the temple and the side of the nose.

The orbital contents comprise the eye the orbital and retrobulbar fascia extraocular muscles cranial nerves II III IV V and VI blood vessels fat the lacrimal gland with its sac and duct the eyelids. While the eyeball is the actual sensory organ the other parts of of the eye are equally important in maintaining the health and function of the eye as a whole. 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.

The lacrimal glands are shaped a bit like an almonds found in the upper part of your eye sockets. Iris anterior limiting membrane posterior limiting membrane tendon of lateral rectus muscleciliary part of retina meridional fibers ciliary muscle ridocorneal angle Scleral venous sinus canal of Schlemm conjunctiva Ora serrataOptic part of retina Equator ChoroidMacula fovea centralis Postremal chamber vitreous chamber. Eye ball anatomy this is a lateral view of the eye ball in its socket in the skull orbital cavity.

The basic function of your lacrimal glands is to produce tears. The eyes are organs in the head that interact with nerves and the brain to produce eyesight. The extraocular muscles are attached to the white part of the eye called the sclera.

The eyelids protect the eyes from foreign material such as dust and dirt. SOURCES AND FLOW Tears are much more complex than mere salty water Tears are introduced into the conjunctival sac to sheet over the eye in a tear film and exit the eye into the nose via the lacrimal excretory drainage system. Youve got two lacrimal glands one located just above each eye.

An eye socket or orbital socket is a part of the skull in which the eye is enclosed. The eyes also can see in varying light and in colour. Muscle and fibrous attachments are preserved as much as feasible.

The choroid continues at the front of the eyeball to form the Iris.
