The six extraocular muscles four rectus and two oblique are located in the retrobulbar space and attach to the sclera and control the movement of the eyeball. Two oblique muscles and four rectus muscles. ORBITAL MUSCLES INTRA-OCULAR EXTRA- OCULAR INVOLUNTARY VOLUNTARY 1Superior tarsal muscle.

Extraocular muscles appear to be directly affected by the surrounding connective tissue which form a fibroelastic pulley system that help the muscles maintain stable positions within the orbit and ensure that contraction of those muscles results in the desired action.

The extraocular muscles are the six muscles that control movement of the eye and one muscle that controls eyelid elevation levator palpebrae. The extraocular muscles EOM are responsible for controlling the movements of the eyeball and upper eyelid.

Each muscle cell is composed of groups of myofibrils called. These muscles are also known as the extrinsic eye muscles distinguishing them from intrinsic eye muscles which are responsible for controlling the movement of the iris. The Orbit and Extraocular Muscles The orbit is the cavity of the skull in which the eye and its appendages are situated.

The extraocular muscles are located within the orbit but are extrinsic and separate from the eyeball itself. The extraocular muscles also extrinsic muscles of eyeball extra-ocular muscles latin. In rodents an additional retractor bulbi muscle surrounds the.
