Cerebral venous hemodynamics and the basicranium of Cebus
American Journal of Physical Anthropology
|July 1, 1980
Summary
Basicranial foramina shape is crucial for understanding primate evolution, especially in fossils. Analyzing these features in Cebus monkeys suggests ancestral catarrhine vascular patterns.
Area of Science:
- Paleoanthropology
- Primatology
- Comparative Anatomy
Background:
- Basicranial foramina are key to studying primate evolution, particularly for fossil species.
- They provide vital clues about the evolution of cerebral vasculature.
- Understanding foraminal morphology is essential for accurate anatomical descriptions.
Purpose of the Study:
- To highlight the importance of foraminal shape in primate basicranial anatomy.
- To analyze hemodynamic properties of cerebral venous drainage in Cebus.
- To infer ancestral catarrhine vascular patterns based on Cebus morphology.
Main Methods:
- Comparative analysis of basicranial foramina in living and fossil primates.
- Morphological description and shape analysis of foramina.
- Hemodynamic assessment of cerebral venous drainage patterns.
Main Results:
- Foraminal shape is a significant factor in primate basicranial analysis.
- Cebus exhibits specific hemodynamic properties in cerebral venous drainage.
- These properties likely reflect patterns present in ancestral catarrhines.
Conclusions:
- The shape of basicranial foramina is critical for primatological research.
- Cebus venous drainage patterns offer insights into ancestral catarrhine vascular evolution.
- Considering foraminal morphology enhances the study of primate cranial anatomy.

Cranial Bones: Superior and Posterior View
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,...

Anatomy of the Brain: Ventricles
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. The...
Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck
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...

Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
