Background: Atlanto-occipital and atlantoaxial assimilation are rare congenital abnormalities characterized by abnormal fusion of the atlas vertebra with the occipital bone or the axis vertebra, respectively, within the craniovertebral junction. These anomalies can significantly alter the biomechanics and structural integrity of the cervical spine, leading to diverse clinical presentations ranging from restricted neck mobility to neurological deficits. Accordingly, this study aims to investigate the prevalence, anatomical abnormalities, and clinical significance of atlanto-occipital and atlantoaxial assimilation in the Asian population.

- The foramen transversarium, located in the cervical vertebrae, is crucial for the passage of essential neurovascular structures, and abnormal ossifications in this area can lead to serious clinical issues.
- A study evaluating 182 dried cervical vertebrae and 190 patients with neck-related problems found various types of abnormal ossifications, including accessory foramina and stenosis.
- Notably, some patients experienced severe conditions like cervical kyphosis and spinal canal stenosis due to these changes, highlighting the importance of recognizing these ossifications for effective diagnosis and management in spinal disorders.
Background: Detailed anatomical knowledge of congenital abnormalities of the lungs is essential for proper evaluation and treatment of respiratory diseases, identification of bronchopulmonary segments during lobectomies and surgical resection, and identification and interpretation of their variable radiological imaging.
Aim: Accordingly, the aim of this study was designed to evaluate the prevalence of congenital abnormal shapes of lungs in relation to abnormal lobes and fissures.
Materials And Methods: This study was carried out on 270 isolated lung specimens (right lungs - 135 and left lungs - 135) from 135 formalin-embalmed middle-aged human cadavers irrespective of gender.
Background: Biceps brachii is an elongated two-headed fusiform muscle of the anterior compartment of the arm which crosses the shoulder as well as the elbow joint. It assists in flexion of the shoulder joint and elbow joint and powerful supinator of the forearm. It also assists in the abduction of the shoulder joint.

Aim: Accordingly the present study was designed to evaluate the anatomical variations of the brachial artery and its morphology, embryogenesis and clinical implications.
Materials And Methods: In an anatomical study 140 upper limb specimens of 70 cadavers (35 males and 35 females) were used and anatomical variations of the brachial artery have been documented.
Background: The ligamentum longitudinale anterius is a broad and strong band of fibrous tissue that runs along the anterior surfaces of the bodies of the vertebrae.
Aim: The study was undertaken to evaluate the incidence of ossified ligamentum longitudinale anterius in adult dry human vertebra.
Materials And Methods: This study was carried out on 95 sets of dry human vertebral columns irrespective of age and sex at Mayo Institute of Medical Sciences- Barabanki,-UP, Melaka Manipal Medical College-Manipal University and Department of Anatomy, KMCT Medical College, Manassery- Calicut, India.
