In anatomy, the orbit [a] is the cavity or socket/hole of the skull in which the eye and its appendages are situated. "Orbit" can refer to the bony socket, [1] or it can also be used to imply the contents. [2]

2023年11月3日 · 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.

2024年6月25日 · The orbits (or eye sockets) are bilateral and symmetrical bony cavities in the head. They enclose the eyeball and its associated structures. In this article, we shall look at the borders, contents and clinical correlations of the bony orbit.

This article provides a detailed illustration and description of the microsurgical anatomy of the orbit, with a focus on the intrinsically complex spatial relationships around the annular tendon and the superior orbital fissure, the transition from cavernous sinus to the orbital apex.

2023年7月24日 · The orbits are bony structures of the skull that house the globe, extraocular muscles, nerves, blood vessels, lacrimal apparatus, and adipose tissue. Each orbit protects the globe, while the supportive tissues allow the globe to move in three dimensions (horizontal, vertical, and torsional).

This article will provide EyeWiki readers with information regarding key bony anatomic landmarks of the orbit.

2024年10月19日 · Gross anatomy. Orbits are roughly pyramidal in shape, broad based anteriorly and tapering to an apex, posteriorly. The normal volume in an adult is approximately 30 mL, of which the globe occupies 6.5 mL. The orbit has a roof, floor, medial and lateral wall.

2023年7月24日 · The following seven bones form the orbit: The orbit is a pear shape, with the optic nerve at the stem, and holds approximately 30 cc volume. The entrance to the globe anteriorly is approximately 35 mm high and 45 mm wide. The depth from orbital rim to the orbital apex measures 40 to 45 mm in adults.

Each orbit is pear-shaped with the optic nerve representing the stem. The medial walls of the orbit are almost parallel and border the nasal cavity anteriorly. The lateral walls, however, diverge at an angle of 45 degrees. Seven bones make up the orbit, namely: Frontal; Zygoma; Maxilla; Ethmoid; Sphenoid; Lacrimal; Palatine
