Summary
The cavernous sinus (CS) is a true venous sinus with distinct anatomical walls. Its structure, including trabeculae, changes with age, supporting the term "cavernous sinus".
Area of Science:
- Anatomy
- Histology
- Vascular Biology
Background:
- The cavernous sinus (CS) has been a subject of anatomical study since 1695.
- Despite extensive research, its precise anatomy and nomenclature remain subjects of discussion.
Purpose of the Study:
- To investigate the detailed anatomy and histology of the cavernous sinus.
- To clarify the structural basis for the term "cavernous sinus".
Main Methods:
- Anatomical and histological examination of 40 human cavernous sinus specimens.
- Inclusion of a newborn specimen to observe developmental changes.
Main Results:
- The CS is defined by two walls: an inferior-medial wall (dura's outer layer) and a superior-lateral wall (both dura layers).
- Sinusoidal veins traverse the lateral wall, connecting tributaries to the CS, which is lined by an endothelial layer.
- Trabeculae within the CS are more numerous in newborns than adults, suggesting age-related changes.
Conclusions:
- The cavernous sinus is confirmed as a true venous sinus.
- The anatomical findings support the continued use of the term "cavernous sinus".

01:18Anatomy of the Brain: Ventricles
4.4K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

01:19Veins of Head and Neck
2.3K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:27Cranial Bones: Lateral View
2.4K
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...

01:20Anatomical Terminology
13.2K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

01:27Liver Histology
1.1K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

01:24Nose and Nasal Cavity
3.4K
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...
