COMPARATIVE ANATOMICAL STUDIES IMPLY ADAPTIVE VARIATIONS OF RUMINANT DIGESTIVE PHYSIOLOGY

Rumen physiology constrains diet niche: linking digestive physiology and food selection across wild ruminant species

Anatomical Variations of Vertebral Artery

Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...

ANATOMICAL VARIATIONS OF THE CHORDA TYMPANI NERVE

The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...
