The lateral compartment of the leg contains the fibularis longus and brevis muscles, responsible for eversion and plantarflexion of the foot. These muscles are innervated by the superficial fibular nerve and receive blood supply from branches of the fibular artery. View Diagram Lateral Compartment of the Leg

The retromandibular vein courses through the parotid gland and drains into the external jugular vein or common facial vein. Its tributaries include the superficial temporal and maxillary veins. Knowledge of the retromandibular vein anatomy is essential for surgeons, radiologists, and View Diagram Retromandibular Vein Course and Tributaries
A typical rib consists of a head, neck, tubercle, and body. The head articulates with the thoracic vertebrae at costovertebral joints, while the tubercle connects with the transverse process. The shaft curves anteriorly and inferiorly, forming the costal angle before View Diagram Structure of a Typical Rib
Coronal sections of the ear show mastoid air cells within the temporal bone, which communicate with the middle ear and help in sound resonance and pressure regulation. Knowledge of mastoid anatomy is essential for ENT surgeons, radiologists, and medical students View Diagram Coronal Section of the Ear Showing the Mastoid Air Cells
The wrist joint involves articulation between the distal radius, articular disc, and proximal carpal bones. This anatomy diagram of the articulating surfaces of the wrist joint illustrates the scaphoid, lunate, and triquetrum articulating with the radius. It highlights the role View Diagram Articulating Surfaces of the Wrist Joint Radius Articular Disk and Carpal Bones
The mastoid fossa is a depression within the temporal bone that houses the mastoid air cells and provides attachment for the sternocleidomastoid and other muscles. Its air cells communicate with the middle ear, playing a role in pressure regulation. Knowledge View Diagram Mastoid Fossa Overview
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 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
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
The perineum is a diamond-shaped region located between the pubic symphysis anteriorly, coccyx posteriorly, and ischial tuberosities laterally. It contains superficial and deep structures, including muscles, nerves, and vessels associated with the urogenital and anal regions. Understanding perineal borders is View Diagram Borders of the Perineum
The ligaments of the lumbar spine provide stability while allowing flexibility. Major ligaments include the anterior and posterior longitudinal ligaments, ligamentum flavum, interspinous, supraspinous, and intertransverse ligaments. The anterior longitudinal ligament prevents hyperextension, while the posterior longitudinal ligament limits hyperflexion. View Diagram Ligaments of the Lumbar Spine
The ankle joint consists of the tibia, fibula, and talus, forming a complex hinge that allows dorsiflexion, plantarflexion, and slight rotation. Ligaments and bony surfaces provide stability while accommodating weight-bearing movements. Knowledge of ankle bones and their articulations is crucial View Diagram Bones of the Ankle Joint Tibia Fibula and Talus
The general structure of a vertebra includes the vertebral body, vertebral arch, spinous and transverse processes, pedicles, laminae, and vertebral foramen. Knowledge of vertebral anatomy is essential for orthopedic surgeons, neurosurgeons, and medical students in managing fractures, spinal instrumentation, or View Diagram General Structure of a Vertebrae
The elbow joint ligaments, including medial (ulnar collateral) and lateral (radial collateral) ligaments, provide stability against varus and valgus stress. They connect the humerus to the ulna and radius, supporting the joint during flexion, extension, and rotational movements. Injury can View Diagram Ligaments of the Elbow Joint Lateral and Medial Aspect
The femoral triangle is an anatomical region in the anterior thigh bounded by the sartorius, adductor longus, and inguinal ligament. It contains key structures including the femoral nerve, artery, vein, and lymphatics. Understanding the borders and contents of the femoral View Diagram Borders of the Femoral Triangle
3D views of the knee joint provide detailed visualization of bones, ligaments, menisci, and cartilage, highlighting the femur, tibia, patella, and surrounding soft tissue structures. Knowledge of knee anatomy is essential for orthopedic surgeons, physiotherapists, and medical students in managing View Diagram Knee 3D
An X-ray of shoulder separation typically shows widening of the acromioclavicular joint. This injury often results from a fall onto the shoulder. The clavicle may appear elevated relative to the acromion. Severity depends on the degree of ligament damage.
The ulna is the medial bone of the forearm in the anatomical position. Proximally, it forms the olecranon and coronoid process, which articulate with the humerus at the elbow. The radial notch allows articulation with the head of the radius. View Diagram Overview of the Anatomical Position of the Ulna
The human skeletal system diagram shows the full structure of bones that support, protect, and shape the body. At the top, the skull protects the brain and forms the face, while the jaw (mandible) allows for chewing and speaking. Moving View Diagram Human Skeletal System Diagram
