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
The posterior surface of the distal femur includes the condyles, intercondylar fossa, popliteal surface, and articular facets for the tibia and patella. These structures articulate with the tibial plateau and patella, contributing to knee joint stability, flexion, and extension.

The fibula is a slender long bone located on the lateral side of the lower leg. This anatomy diagram of the anatomy of the fibula highlights its proximal head, shaft, and distal lateral malleolus. It demonstrates its articulation with the View Diagram Anatomy of the Fibula
A Monteggia fracture involves a fracture of the proximal ulna accompanied by dislocation of the head of the radius at the elbow. It usually results from a fall on an outstretched hand with the forearm in excessive pronation. The injury View Diagram Monteggia Fracture of the Radius and Ulna
Brown-Séquard syndrome is a spinal cord lesion caused by hemisection, leading to ipsilateral motor paralysis and loss of proprioception with contralateral loss of pain and temperature sensation. Knowledge of spinal cord anatomy and tract organization is essential for neurologists, neurosurgeons, View Diagram Brown Sequard Syndrome Spinal Cord Lesion
The borders of the heart include the right, left, superior, and inferior borders formed by the atria and ventricles. The right border is mainly the right atrium, the left border the left ventricle and auricle, the superior border the atria View Diagram Borders of the Heart
A lateral view of the scapula highlights the glenoid fossa, acromion, and coracoid process, showing articulation with the humeral head and providing attachment for shoulder muscles. Knowledge of these landmarks is essential for orthopedic surgeons, radiologists, and medical students in View Diagram Lateral View of the Scapula Glenoid Fossa Acromion and Coronoid Process Labelled
The brainstem consists of the midbrain, pons, and medulla oblongata, connecting the cerebrum with the spinal cord. It contains nuclei for cranial nerves, vital centers controlling respiration, cardiac function, and consciousness. Knowledge of brainstem anatomy is essential for neurologists, neurosurgeons, View Diagram Brain stem
The subtalar joint, formed between the talus and calcaneus, allows inversion and eversion of the foot. It is stabilized by ligaments including the interosseous talocalcaneal and cervical ligaments. Knowledge of subtalar joint anatomy is essential for orthopedic surgeons, podiatrists, and View Diagram The Subtalar Joints and Ligament
The patella has distinct anterior and posterior surfaces that serve protective and articulating functions. This anatomy diagram of the anterior and posterior surfaces of the patella illustrates the rough anterior surface for tendon attachment and the smooth posterior articular surface View Diagram Anterior and Posterior Surfaces of the Patella
The metacarpophalangeal joints connect the metacarpals to the proximal phalanges. They are condyloid synovial joints allowing flexion, extension, abduction, adduction, and circumduction. Collateral ligaments stabilize the joints, while the joint capsules and synovial fluid facilitate smooth movement. These joints are View Diagram Structures of the Metacarpophalangeal Joint
The triangular space is an anatomical region in the posterior shoulder bordered by the teres minor, teres major, and long head of the triceps. It contains the circumflex scapular artery and provides a pathway for blood supply to the scapular View Diagram Borders of the Triangular Space
The pubis forms the anterior portion of the hip bone and includes the pubic body, superior and inferior pubic rami, and the pubic symphysis, where the two sides meet at the midline. Its bony surfaces provide attachment points for muscles View Diagram Bony Landmarks of the Pubis
The ilium contains several key bony landmarks that help define the hip bone and provide attachment sites for muscles and ligaments. The wing, or ala, of the ilium forms the broad, flared superior portion and supports the iliac fossa on View Diagram Bony Landmarks of the Ilium Wing ASIS PSIS Hip Bone.
A BennettÂ’s fracture is a fracture-dislocation at the base of the first metacarpal bone where it meets the trapezium, usually caused by a sudden axial load through a flexed thumb, such as during a fall or high-impact grip. The break View Diagram Bennetts Fracture of the 1st Metacarpal
