The kidneys receive a rich vascular supply essential for filtration and homeostasis. This anatomy diagram of the arterial and venous supply to the kidneys illustrates the renal arteries branching directly from the abdominal aorta and entering the hilum. It highlights View Diagram Arterial and Venous Supply to the Kidneys
The left gastro-omental artery arises from the splenic artery along the greater curvature of the stomach. It supplies the stomachÂ’s fundus and body and contributes to anastomoses with the right gastro-omental artery. This vascular arcade is important for maintaining perfusion, View Diagram Left Gastro Omental Artery
Neurones can be structurally classified as multipolar, bipolar, or unipolar (pseudounipolar). Multipolar neurones have one axon and multiple dendrites and are common in the central nervous system. Bipolar neurones have one axon and one dendrite and are found in sensory View Diagram Structural Classifications of a Neurone
The distal end of the spinal cord includes the conus medullaris and lumbar cistern, containing cerebrospinal fluid and nerve roots of the cauda equina. The lumbar cistern extends from the conus to the sacral region, providing a safe site for View Diagram Distal End of the Spinal Cord The Lumbar Cistern
Typical thoracic vertebrae have distinguishing features including a heart-shaped vertebral body, costal facets for rib articulation, and long, downward-sloping spinous processes. They provide stability, support for the thoracic cage, and articulation for ribs. Knowledge of thoracic vertebra anatomy is essential View Diagram Distinguishing Features of a Typical Thoracic Vertebrae
The suboccipital triangle, located deep in the posterior neck, is bordered by the rectus capitis posterior major, obliquus capitis superior, and obliquus capitis inferior muscles. The vertebral artery and suboccipital nerve pass through this space. Knowledge of its borders and View Diagram Suboccipital Triangle Borders and Vertebral Artery
The carpal bones of the hand are eight small bones arranged in proximal and distal rows forming the wrist joint. These include the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate. They articulate with the radius, ulna, metacarpals, and View Diagram Diagram of the Carpal Bones of the Hand
The medullary pyramids are paired structures on the ventral surface of the medulla oblongata, containing corticospinal tracts responsible for voluntary motor control. Knowledge of pyramidal anatomy is essential for neurologists, neurosurgeons, and medical students in managing strokes, lesions, or neurodegenerative View Diagram Medullary Pyramids
The muscles of mastication include the medial and lateral pterygoids, which move the mandible for elevation, protrusion, and side-to-side motion. The medial pterygoid elevates and assists in grinding, while the lateral pterygoid protracts and depresses the mandible. They are innervated View Diagram Muscles of Mastication Medial and Lateral Pterygoids
The facial vein collects venous blood from the superficial face, connecting with the angular, superior labial, and retromandibular veins. It communicates with the cavernous sinus via the ophthalmic veins, forming potential pathways for infection. Understanding its course is crucial in View Diagram Facial Vein Course and Tributaries
Posterior venous drainage of the heart involves cardiac veins, including the coronary sinus, great, middle, and small cardiac veins, returning deoxygenated blood to the right atrium. Knowledge of venous anatomy is essential for cardiologists, cardiac surgeons, and medical students in View Diagram Posterior View of the Venous Drainage of the Heart
The blood supply to the scaphoid bone is mainly through branches of the radial artery, entering via dorsal and volar surfaces. The proximal pole receives limited blood flow, making it susceptible to avascular necrosis following fractures. Knowledge of scaphoid vascular View Diagram Blood Supply to the Scaphoid Bone
Ectopic pregnancy occurs when a fertilized egg implants outside the uterine cavity, most commonly in the uterine tube. As the embryo grows, it can cause stretching and eventual rupture of the tube, leading to severe internal bleeding. Patients often present View Diagram Ectopic Pregnancy
The paranasal sinuses are air-filled cavities within the skull that reduce weight and enhance voice resonance. This anatomy diagram of the anatomy of the paranasal sinuses illustrates the frontal, maxillary, ethmoidal, and sphenoidal sinuses. It highlights their drainage pathways into View Diagram Anatomy of the Paranasal Sinuses
The anterolateral abdominal wall muscles include external oblique, internal oblique, transversus abdominis, and rectus abdominis. They support abdominal contents and assist in trunk movement.
The duodenum is divided into four parts: superior, descending, horizontal, and ascending. It begins at the pylorus and ends at the duodenojejunal flexure. The descending part receives bile and pancreatic secretions. Its C-shaped curve surrounds the head of the pancreas View Diagram Parts of the Duodenum Small Intestine
Finger movements include abduction and adduction, controlled by the dorsal and palmar interossei and lumbrical muscles. Abduction moves fingers away from the midline of the hand, while adduction brings them closer. These actions are essential for grip, precision tasks, and View Diagram Finger Abd Add
The pancreas receives blood supply from branches of the splenic artery and vein, including pancreaticoduodenal branches, supporting endocrine and exocrine function. Knowledge of pancreatic vasculature is essential for surgeons, radiologists, and medical students in planning resection, managing trauma, or interpreting View Diagram Vasculature of the Pancreas Splenic Artery and Vein
The deep muscles of the gluteal region, including the piriformis, obturator internus, gemelli, and quadratus femoris, stabilize and rotate the hip. Knowledge of their anatomy is essential for orthopedic surgeons, physiotherapists, and medical students in managing hip injuries, planning surgery, View Diagram Deep Muscles of the Gluteal Region
Radiographs of a fractured patella reveal the location, type, and displacement of the fracture. The patella serves as a sesamoid bone within the quadriceps tendon, enhancing knee extension leverage. Understanding patellar anatomy is critical in orthopedics, emergency care, and physiotherapy. View Diagram Radiograph of Fractured Patella
