Dec 18, 2020 · This chapter provides a description of the superficial anatomy, the osteology, and the musculature of the orbit and periorbital region, and drainage of lacrimal fluid. The vasculature of the orbit is outlined highlighting the extensive vessel anastomoses in the...

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.

Anatomy of the Periorbital Region. The general anatomy of the non-globe periorbital region is depicted in Figure 1. The definitions for the terms utilized in describing the features within this region are listed alphabetically. The anatomy of the various structures is described in more detail below. Figure 1. Figure 2. Figure 3. Brow:

May 26, 2017 · Anatomy of the most well-developed supporting system of the medial rectus muscle that reaches the inferior wall, the inferior rectus muscle, and the superior muscle complex.

Nov 12, 2020 · The periorbita, also called the orbital periosteum or orbital fascia, covers the bones of the orbit. This dense connective tissue membrane serves as an attachment site for muscles, tendons, and ligaments and is a support structure for the blood supply to …

The periorbita (orbital periosteum; orbital fascia) is a dense connective tissue membrane that covers the bones of the orbit. It serves as an attachment site for muscles, tendons, and ligaments and is a support structure for the blood supply to the orbital bones.

Following are the main structures that make up the anatomy of the orbitopalpebral region: The main function of the orbit is to give support and protection to the eyeball and its structures. The volume of the orbital cavity of an adult is approxi-mately 30cc.

Nov 3, 2023 · Superior tarsus is associated with muscles that raise the upper eyelid. Conjunctiva - thin membrane that covers the posterior surface of the eyelid and reflects onto the anterior surface of the eyeball.

May 18, 2020 · Movement of the brow is produced through the action of brow elevators and depressors and is enhanced by the presence of the galeal fat pad, glide plane space and subgaleal space. The periosteum of the frontal bones is reflected at the arcus marginalis to become the periorbita of the periorbital bones.
