A quantitative study on the retial arteries in one-humped camels

Area of Science:

• Veterinary Anatomy
• Neurovascular Anatomy
• Comparative Anatomy

Background:

• The rostral epidural rete mirabile is a complex vascular structure at the base of the brain.
• Understanding its formation and blood supply is crucial for comprehending cerebral circulation in camels.

Purpose of the Study:

• To investigate the anatomical composition and quantitative blood supply of the camel's rostral epidural rete mirabile.
• To determine the proportional contribution of key arteries to this vascular network.

Main Methods:

• Camel brains were dissected after latex injection of arteries.
• Gross and quantitative analyses were performed on the rostral epidural rete mirabile.
• Vessel diameters were measured to estimate blood supply ratios.

Main Results:

• The rostral epidural rete mirabile is formed by branches of the maxillary, external ophthalmic, and internal carotid arteries.
• The maxillary artery branches supplied the largest proportion of blood (76.41%).
• The internal carotid artery contributed 13.33% and the external ophthalmic artery contributed 10.26%.

Conclusions:

• The maxillary artery is the primary source of blood for the camel's rostral epidural rete mirabile.
• This study provides quantitative data on the vascularization of a key cerebral structure in camels.
• Findings contribute to the understanding of specialized vascular adaptations in camelid brains.
