Objectives: To determine the percentage and type of aortic arch variations in Indian subjects and their clinical and surgical importance and embryological basis. Patients and methods: In our investigation, branching patterns of the aortic arch were studied in 62 formalin-fixed cadavers of both sexes of Indian origin, aged 45-79. The dissections were carried(More)
The functional morphology and evolution of the superficial forearm flexor, the palmaris longus, have long fascinated kinesiologists, physical anthropologists and anatomists alike. The anomalies, agenesis, variations and polymorphic presentation of the muscle, coupled with its biomechanical role in the performance of flexion and supination through distal(More)
INTRODUCTION The male gonadal arteries, namely the testicular arteries, may vary at their origin and arise from the renal artery, suprarenal artery or lumbar artery. They may also be doubled, tripled or even quadrupled and may arise as a common trunk. With the advent of new intra-abdominal operative and laparoscopic techniques, the anatomy of the gonadal(More)
During routine osteology demonstration of the posterior cranial fossa we noticed a transverse bony canal in the middle third of the clivus of an adult male skull. The canal was situated 1.8 cm in front the anterior border of the foramen magnum. The length of the canal was 0.6 cm long. The possible embryological basis and clinical significance of the(More)
INTRODUCTION The organogenesis of the thyroid gland in humans is often disturbed, leading to a variety of morphological variations of the gland, such as hypoplasia, ectopy, hemiagenesis and agenesis. As the morphological variations are usually diagnosed incidentally during examination for other thyroid gland diseases, the true incidence is therefore(More)
BACKGROUND Awareness of the anatomy and variations of the extensor tendons on the dorsum of the hand is necessary when assessing the traumatized or diseased hand and when considering tendons for repair or transfer. A complete quantitative documentation of the extensor tendons is lacking. METHOD The arrangements of extensor tendons to the medical four(More)
Incomplete or complete ossification of the pterygospinous ligament is uncommon. Entrapment of mandibular nerve and its branches was reported due to this anatomical variation, when found. The aim of the present study is to investigate the incidence of the pterygospinous bony bridges in Indian dry skulls. A total of 416 adult dry skulls of Indian origin were(More)
CONTEXT It was suggested that the accessory neurovascular foramina of the mandible might be of significance in relation to the effectiveness of local anesthesia following the routine inferior alveolar nerve block. AIMS To investigate the incidence of neurovascular foramina over the lingual surface of the mandible in South Indian population. SETTINGS AND(More)
OBJECTIVES The goal of the study was to evaluate the gross morphology of the coronal, sagittal and lambdoid sutures in human adult dried skulls and to determine if any difference exists in terms of patency. MATERIALS AND METHODS The study included 78 human dry skulls of Indian population. The coronal, sagittal and lambdoid sutures were analyzed using the(More)
Anatomical variations of peripheral nerves are important and can help explain otherwise incomprehensible clinical findings. A study of 26 right and 18 left formalin-preserved upper limbs identified the fact that the musculocutaneous nerve is subject to considerable anatomical variation, including communication with the median nerve. A study of its branching(More)
