Detailed explanation-1: -The orbital cavity contains the globe, nerves, vessels, lacrimal gland, extraocular muscles, tendons, and the trochlea as well as fat and other connective tissue.

Detailed explanation-2: -By definition, the orbit (bony orbit or orbital cavity) is a skeletal cavity comprised of seven bones situated within the skull. The cavity surrounds and provides mechanical protection for the eye and soft tissue structures related to it.

Detailed explanation-3: -The orbit is the bony cavity in the skull that houses the globe of the eye (eyeball), the muscles that move the eye (the extraocular muscles), the lacrimal gland, and the blood vessels and nerves required to supply these structures.

Detailed explanation-4: -Although the orbit is commonly described as pyramidal in shape, it is not an angular structure, and the walls are not regular. Rather, its walls, apex, and base are curvilinear and are perforated by foramina and fissures, and they have several irregularities where ligaments, muscles, and capsules attach.
