Concurrent variations of left testicular vessels.

Knowledge of variations of the testicular vessels is essential for urologists, radiologists, and surgeons in general, as iatrogenic injuries of these vessels may affect the spermatogenesis severely. Though variations of testicular vessels are common, combined variations of these vessels are rare. We observed concurrent variations of left testicular vessels in an adult cadaver aged 70 years.

Possible effects of radiofrequency electromagnetic radiation on contextual fear conditioning, hippocampal perivascular space, apoptosis and adrenal gland microarchitecture in rats.

Whilst the world sees the tremendous growth of mobile phone technology, radiofrequency electromagnetic radiation (RF-EMR) induced possible health effects have emerged as a topic of recent day debate. The current study is designed to test the hypothesis that chronic 900 MHz radiation exposure would potentially dysregulate the stress response system (HPA axis) in vivo, via, its non-thermal mechanisms, leading to alterations in the microarchitecture of the adrenal gland, vulnerable brain regions such as the hippocampus which may results in altered behaviours in rats. Male albino Wistar rats aged four weeks, weighing 50-60 g were subjected to 900 MHz radiation from a mobile phone for four weeks at a rate of one hour per day.

Variant anatomy of the iliac veins and presence of two venous rings around the arteries in the pelvis.

Internal iliac vein drains the pelvic viscera, gluteal region, and the perineal region. Knowledge of its variations is of importance to radiologists, gynecologists, and orthopedic surgeons. We found one of the rare variations of the internal iliac vein during our cadaveric dissections.

A rare anomalous muscle in the popliteal region - a case report.

Anomalous muscles are rarely seen in the popliteal region of the lower limb. Some of them are harmless and go unnoticed and some create problems such as neuropathies. We report a novel case of an unusual additional muscle in this region.

An unreported variant of palmaris longus muscle.

Palmaris longus is a highly variable muscle of the forearm. Knowledge of its variability is of importance to plastic surgeons, hand surgeons and radiologists. During our routine dissection classes for undergraduate medical students, a peculiar palmaris longus muscle was noted in the left upper limb of an adult male cadaver.

Vesico-obturator venous plexus - a rare termination of obturator vein.

Obturator vein usually terminates into the internal iliac vein. Its variations are the cause major bleeding problems in pelvic surgeries. We observed a rare variation in the termination of the right obturator vein.

A rare femoral venous ladder encircling the femoral artery.

Femoral vein is increasingly used for venous cannulation procedures. Its anomalies in the femoral triangle could complicate these procedures. We report an extremely rare type of femoral venous ladder observed during routine cadaveric dissections.

Morphometric evaluation of the orbital region for sex determination in a Saudi Arabian population using 3DCT images.

In forensic anthropology, the analysis of variations in the orbitometric features plays a crucial role in identifying the sex of a skull detached from its skeleton. Therefore, it is essential to create population-specific values to maximize the accuracy rate of sex estimation. The objective of this study was to evaluate the orbital region morphometrically for sex determination in a Saudi Arabian population using CT scan images.

Multiple renal veins clogging the hilum of the right kidney.

Knowledge of variations of renal vessels is of utmost importance in retroperitoneal surgeries and kidney transplant surgeries. We report concurrent variations of the right renal vessels, observed in an adult male cadaver during dissection classes. The right kidney was supplied by three renal arteries, out of which two entered the kidney through the hilum and the other one entered through the lower pole of the kidney.

Multiple venous variations at the abdominopelvic region: a case report.

Knowledge of vascular variations of the abdominopelvic junction is of importance to surgeons, radiologists, orthopaedic surgeons and other medical disciplines. We report a rare combination of venous variations observed at the abdominopelvic junction of an adult male cadaver. The right common iliac vein was absent.

Terminal bifurcation of the external jugular vein: a rare variation.

Variations of external jugular vein are common. Here, we present a rare terminal bifurcation of the left external jugular vein. The left external jugular vein was formed by the union of entire retromandibular vein and posterior auricular vein.

A rare additional lobe of cerebellum, projecting from its superior surface.

Human cerebellum plays a vital role in motor coordination, regulation of muscle tone and maintaining the equilibrium of the body. It seldom shows anatomical/morphological variations. Herein, we report the presence of a small additional lobe projecting out on the superior surface of the right cerebellar hemisphere in the para-vermal area in an adult male cadaver.

An anomalous muscle clinging around the inferior belly of omohyoid muscle.

Sternohyoid, sternothyroid, omohyoid and thyrohyoid muscles belong to a group of muscles called infrahyoid muscles. A few variations of these muscles and additional muscles in this area have been reported. We report an anomalous muscle in this area.

Morphometric analysis of foramen magnum and occipital condyle using CT images for sex determination in a Saudi Arabian population.

Objective Of The Study: The objective of this study was to evaluate FM and occipital condyles measurements morphometrically for sex determination by using discriminant function analysis and to note visually the variation in the shape of the foramen magnum in a Saudi Arabian population by using CT scan images.

Material And Methods: This study included 472 CT scans (236 males and 236 females; age range, 18-72 years). The foramen magnum shapes were classified into 8 types: oval, egg, round, hexagonal, pentagonal, tetragonal, irregular (A) and irregular (B).

Saphenous Ladder Formed by Almost Completely Duplicated Great Saphenous Vein.

Knowledge of normal as well as variant great saphenous vein is useful as it is the vein that can get varicosed; the vein that is used in bypass surgeries and the vein that is used for cannulation purpose. We observed almost complete duplication of the great saphenous vein in the left lower limb of an adult male cadaver. Both the great saphenous veins arose from the medial end of the dorsal venous arch and coursed parallel to each other throughout the limb.

Sternocleidohyoid muscle: an unreported variant of cleidohyoid muscle.

Sternohyoid, sternothyroid, omohyoid, and thyrohyoid muscles are collectively known as infrahyoid muscles. These muscles frequently show variations in their attachments. Here, an extremely rare variant muscle belonging to this group has been presented.

Surgical and embryological perspective of a big loop of internal carotid artery extending laterally beyond internal jugular vein.

Knowledge of variations of the internal carotid artery is significant to surgeons and radiologists. The internal carotid artery normally runs a straight course in the neck. Its anomalies can lead to its iatrogenic injuries.

Triple right testicular veins and their variant termination and communications.

Testicular veins are known to show many variations in their origin, course and termination. Some of their variations can lead to male sterility. We report a unique variation of right testicular vein here.

Anomalous peritoneal band connecting greater omentum to the ascending colon: a possible cause for dilation of ascending colon.

Anomalies of the peritoneum and the colon are quite common. Some of these anomalies can disturb the normal digestive and absorptive functions of the intestine and the others might result in formation of volvulus or impede the blood supply of the intestine. We report a rare, combined variation of peritoneum and ascending colon.

Fenestrated Falx Cerebri and Additional Sinuses in the Tentorium Cerebelli.

Morphological variations of falx cerebri and tentorium cerebelli are extremely rare. The authors report an extremely rare type of combined variation of falx cerebri and dural venous sinuses in the tentorium cerebelli. During the removal of the brain from cranial cavity, it was noted that the anterior part of the falx cerebri had fenestrations and it looked like a mesh.

Anomalous Course of Facial Artery Through the Submandibular Gland and its Redundant Loop at the Base of Mandible.

Knowledge of variant course and branching pattern of the facial artery gains importance in the surgeries of upper neck and face. The authors report a unilateral anomalous course and a redundant loop of right facial artery as seen in an adult male cadaver. The right facial artery had its origin from the external carotid artery.

Transposition and variant termination of azygos and hemiazygos veins: an extremely rare variation.

Azygos system of veins is the main source of venous drainage from the thoracic wall. Knowledge of azygos vein anomalies could be of importance to cardiothoracic surgeons and radiologists. We report a rare variation of azygos vein as seen in an adult male cadaver aged 65 years approximately.
