3D views of the scapula reveal the spine, acromion, coracoid process, glenoid cavity, and muscle attachment sites, providing a clear understanding of shoulder mechanics. Knowledge of scapular anatomy is essential for orthopedic surgeons, physiotherapists, and medical students in managing fractures, View Diagram Scapula 3D
Overview of the Bones of the Hand Carpals Metacarpals and Phalanges
The bones of the hand consist of the carpals, metacarpals, and phalanges, forming a complex structure that allows fine motor movements, grasping, and dexterity. The eight carpal bones form the wrist, connecting the forearm to the hand, while the five View Diagram Overview of the Bones of the Hand Carpals Metacarpals and Phalanges
The Menisci of the Knee Joint Superior View
The menisci of the knee are crescent-shaped fibrocartilaginous structures that deepen the tibial articular surfaces. The medial meniscus is C-shaped and more firmly attached, making it more prone to injury. The lateral meniscus is more circular and relatively mobile. They View Diagram The Menisci of the Knee Joint Superior View
Lumbar Spine
The lumbar spine consists of five large vertebrae (L1L5) forming a lordotic curve in the lower back. These vertebrae provide stability, bear body weight, and allow flexion, extension, and limited rotation. Intervertebral discs act as shock absorbers, while ligaments and View Diagram Lumbar Spine
Ligaments of the Liver Coronary Falciform Triangular
The liver ligaments, including the coronary, falciform, and triangular ligaments, anchor the organ to the diaphragm and anterior abdominal wall. These folds of peritoneum stabilize the liver while allowing some mobility. They also contain vessels and lymphatics essential for hepatic View Diagram Ligaments of the Liver Coronary Falciform Triangular
Course of the Superior Thoracic Artery
The superior thoracic artery arises from the axillary artery and supplies the pectoralis major and minor muscles, upper chest wall, and adjacent structures. It forms anastomoses with intercostal arteries and contributes to collateral circulation in the thoracic region. Its course View Diagram Course of the Superior Thoracic Artery
Overiview of Uterus Uterine Tubes and Ovaries. Includes Round and Ovarian Ligaments
The uterus, uterine tubes, and ovaries form the internal female reproductive system. The uterus is a muscular organ where implantation and fetal development occur. The uterine tubes transport the ovum from the ovary to the uterus and provide the site View Diagram Overiview of Uterus Uterine Tubes and Ovaries. Includes Round and Ovarian Ligaments
Course of the Great Auricular Nerve
The great auricular nerve is a sensory branch of the cervical plexus, arising from the ventral rami of C2 and C3. It ascends vertically across the sternocleidomastoid muscle toward the parotid region, providing sensation to the skin over the parotid View Diagram Course of the Great Auricular Nerve
Anatomical Course of the Deep Brachial Artery
The deep brachial artery, also known as the profunda brachii artery, is a key vessel supplying the posterior compartment of the arm. This anatomy diagram of the anatomical course of the deep brachial artery shows its origin from the brachial View Diagram Anatomical Course of the Deep Brachial Artery
C Spine
The cervical spine consists of seven vertebrae forming the upper portion of the vertebral column, supporting the head and protecting the spinal cord. It allows mobility through flexion, extension, rotation, and lateral bending while maintaining stability. Knowledge of cervical spine View Diagram C Spine
Bony Landmarks and Foramina of the Posterior Cranial Fossa
The posterior cranial fossa contains key bony landmarks and foramina such as the foramen magnum, jugular foramen, and internal acoustic meatus. These structures transmit cranial nerves and major vessels while supporting the cerebellum and brainstem. Understanding the posterior cranial fossa View Diagram Bony Landmarks and Foramina of the Posterior Cranial Fossa
Structure of the Testes and Epididymis
The testes are paired male gonads responsible for sperm production and testosterone secretion. Each testis is surrounded by a fibrous tunica albuginea, and internally divided into lobules containing seminiferous tubules. Sperm produced here pass into the rete testis and efferent View Diagram Structure of the Testes and Epididymis
Micrographc of Compact Bone Osteon
A micrograph of compact bone shows the highly organized structure of osteons, also known as Haversian systems. Each osteon consists of concentric lamellae arranged around a central Haversian canal that contains blood vessels and nerves. Between the lamellae are lacunae View Diagram Micrographc of Compact Bone Osteon
Middle Cerebral Artery Infarct
The middle cerebral artery (MCA) supplies lateral portions of the frontal, temporal, and parietal lobes. Infarcts in the MCA territory can cause contralateral hemiparesis, sensory deficits, aphasia, and visual field defects. Imaging and clinical correlation help localize the stroke and View Diagram Middle Cerebral Artery Infarct
Sagittal View of the Knee Joint Diagram of the Knee Bursae
The knee joint is a complex hinge joint, reinforced by multiple bursae that reduce friction between bones, tendons, and muscles. On sagittal view, the joint shows articulations between the femur, tibia, and patella, with the menisci cushioning the tibiofemoral interface. View Diagram Sagittal View of the Knee Joint Diagram of the Knee Bursae
Cutaneous Innervation of the Lower Leg Ankle
Cutaneous innervation of the lower leg and ankle involves branches of the saphenous, superficial fibular, sural, and tibial nerves, providing sensation to the anterior, lateral, and posterior compartments. Knowledge of this innervation is essential for surgeons, anesthetists, and medical students View Diagram Cutaneous Innervation of the Lower Leg Ankle
Articulations of the Elbow Joint
The elbow joint consists of articulations between the humerus, radius, and ulna, allowing for flexion, extension, and rotation of the forearm. Key structures include the trochlea, capitulum, olecranon, and radial head, which interact to provide smooth and stable movement. Ligaments View Diagram Articulations of the Elbow Joint
The Lacrimal Apparatus
The lacrimal apparatus consists of lacrimal glands, ducts, sac, and nasolacrimal duct, facilitating tear production, distribution, and drainage. Knowledge of its anatomy is essential for ophthalmologists, ENT surgeons, and medical students in managing epiphora, dacryocystitis, or surgical procedures.

Origin of the Spinal Nerves from the Spinal Cord
The spinal nerves originate from the spinal cord through paired dorsal (sensory) and ventral (motor) roots that merge to form mixed nerves. Each nerve corresponds to a specific spinal segment and exits the vertebral column through intervertebral foramina. Understanding spinal View Diagram Origin of the Spinal Nerves from the Spinal Cord
