Summary
The orbital septum in the lateral canthus attaches near the lateral commissure and orbital rim. This precise anatomical finding clarifies the orbital septum
Area of Science:
- Ophthalmology
- Anatomy
Background:
- The precise anatomical attachments of orbital structures are crucial for understanding ocular function and surgical interventions.
- The lateral canthus region presents complex anatomical relationships that require detailed investigation.
Purpose of the Study:
- To precisely delineate the attachment site of the orbital septum within the lateral canthus.
- To provide detailed anatomical insights for ophthalmic surgery and research.
Main Methods:
- Gross dissection of the orbital septum in the lateral canthus of nine Japanese cadaveric specimens (aged 66-85 years).
- Exenteration of two specimens for detailed lateral and superior anatomical exploration.
Main Results:
- The orbital septum attaches slightly lateral to the lateral commissure, connecting with the levator aponeurosis and lower eyelid retractors.
- Attachment to the arcus marginalis and the presence of fat tissue between the orbital septum and lateral retinaculum were observed.
Conclusions:
- The orbital septum's attachment in the lateral canthus is primarily around the lateral commissure and orbital rim.
- This detailed anatomical description enhances understanding of the orbital septum's role in facial anatomy.

2.0K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:17Accessory Structures of the Eye
1.5K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:20Muscles of the Eye
1.1K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

01:14Cranial Bones: Superior and Posterior View
2.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:24Nose and Nasal Cavity
1.8K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
