7 cze 2024 · 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.

19 wrz 2008 · We will first describe the anatomic spaces of the orbit and summarize the pathology within these spaces, even if some of these pathologies are not visible radiologically. Then we will discuss the radiological findings in certain orbital diseases.
2 paź 2024 · This anatomical module of e-Anatomy is dedicated to the anatomy of the normal orbit on MRI. The orbital cavity includes the eyeball, the extraocular muscles, the lacrimal apparatus and the optic nerve.
20 sie 2019 · Anatomy The soft tissue structures of the orbit are contained within a bony cavity and include the globe, extraocular muscles, optic nerve–sheath complex, lacrimal apparatus, and various vascular and nerve structures ( Figs. 20-1 to 20-4 ).
11 lut 2024 · The bony orbit refers to the bones that constitute the margins of the orbits, that is the roof, medial and lateral walls and floor. The orbital margin or rim refers to the anterior circular margin of the orbit.
Each orbit is a complex structure housing the globe, multiple cranial nerves, muscles, vascular structures, which support the visual sense. Many of these structures have been delineated in careful detail by anatomists but remain beyond the resolution of conventional imaging techniques.
8 lis 2018 · The anatomy of the orbit and its contents has been thoroughly reviewed by many authors (10,11,12). The ease of imaging in multiple planes, coupled with the high inherent contrast of intraorbital structures as visualized by MRI, makes the anatomy of the orbit ideal for evaluation by this modality.
