The cerebellum is positioned in the posterior cranial fossa beneath the occipital lobes of the brain. This anatomy diagram of the anatomical position of the cerebellum illustrates its location posterior to the brainstem and its separation from the cerebrum by View Diagram Anatomical Position Cerebellum
X-rays of rickets reveal characteristic changes in bones due to vitamin D deficiency, including widened, cupped, and frayed metaphyses, especially at the wrist and knee. Rickets affects bone mineralization in children, leading to deformities like bowing of long bones and View Diagram X Ray of Rickets
The posterior triangle of the neck is bounded anteriorly by the sternocleidomastoid, posteriorly by the trapezius, and inferiorly by the clavicle. The floor is formed by several muscles including the splenius capitis, levator scapulae, and scalene muscles. This space contains View Diagram Posterior Triangle of the Neck Borders and Muscles of the Floor
The midbrain at the level of the inferior colliculi contains the tectum, cerebral aqueduct, periaqueductal gray, and nuclei controlling auditory reflexes. Knowledge of internal midbrain anatomy is essential for neurologists, neurosurgeons, and medical students in managing tumors, vascular lesions, or View Diagram Internal Anatomy of the Midbrain Level of the Inferior Colliculi
The cerebellum is divided into three anatomical lobes: anterior, posterior, and flocculonodular. This anatomy diagram of the anatomical lobes of the cerebellum highlights their separation by the primary and posterolateral fissures. It illustrates functional correlations, including coordination of voluntary movement, View Diagram Anatomical Lobes of the Cerebellum
The ovoid hiatus of the fascia lata is an opening in the deep fascia of the thigh allowing passage of structures such as the great saphenous vein and lymphatics into the femoral triangle. Knowledge of this anatomical feature is essential View Diagram Ovoid Hiatus of the Fascia Lata
The pectinate line in the anal canal demarcates an important anatomical and functional boundary. Located approximately two-thirds of the way down the canal, it separates the upper columnar epithelium from the lower stratified squamous epithelium. This line corresponds to differences View Diagram The Pectinate Line Anal Canal
The nerve point of the neck is a clinically important region where multiple cutaneous branches of the cervical plexus emerge, including the lesser occipital, great auricular, transverse cervical, and supraclavicular nerves. This area, located along the posterior border of the View Diagram The Nerve Point of the Neck
At the optic chiasm, fibers from the medial halves of each retina cross to the opposite side. These medial fibers carry information from the temporal visual fields. This partial crossing allows visual information from the same visual field to be View Diagram Medial Fibres Crossing over at the Optic Chiasm
Measuring the female pelvis involves assessing obstetric and diagonal conjugates to determine pelvic capacity for childbirth. The obstetric conjugate measures the narrowest anteroposterior diameter of the pelvic inlet, while the diagonal conjugate extends from the sacral promontory to the pubic View Diagram Measuring the Female Pelvis Obstetric and Diagonal Conjugates
The cerebrum is divided into frontal, parietal, temporal, and occipital lobes. Each lobe has specialized functions such as motor control, sensation, hearing, vision, and higher cognition.
The perineum is the anatomical region between the pubic symphysis, coccyx, and ischial tuberosities, divided into urogenital and anal triangles. It contains muscles, fascia, neurovascular structures, and openings for the urethra, vagina, and anus. Understanding perineal anatomy is crucial in View Diagram Overview of the Perineum
The ventricular system includes paired lateral ventricles, the third ventricle, cerebral aqueduct, and fourth ventricle, forming a pathway for cerebrospinal fluid circulation. Superior views of ventricular casts illustrate the precise arrangement of cavities and foramina. This system cushions the brain, View Diagram Superior View of Cast of Ventricular System
The spermatic cord is a vital structure of the male reproductive system that suspends the testis within the scrotum. This anatomy diagram of the anatomical course of the spermatic cord shows its formation at the deep inguinal ring, passage through View Diagram Anatomical Course of the Spermatic Cord
The bony orbit houses the globe, extraocular muscles, optic nerve, and orbital vasculature. Arteries such as the ophthalmic artery supply the eye and surrounding structures, while cranial nerves III, IV, V1, and VI control movement and sensation. Ligaments, connective tissue, View Diagram Contents of the Bony Orbit Arteries Optic Nerve and Muscles
The anterior view of the borders of the cubital fossa demonstrates its triangular boundaries formed by the brachioradialis and pronator teres muscles. This anatomy diagram highlights surface landmarks and underlying structures. It provides a clear understanding of the region used View Diagram Anterior View of the Forearm Borders of the Cubital Fossa
The prepubic and infrapubic angles of the male urethra refer to anatomical curves along the urethra that influence urinary flow and catheterization. Knowledge of these angles is essential for urologists, surgeons, and medical students in performing urethral instrumentation, managing strictures, View Diagram Prepubic and Infrapubic Angles of the Male Urethra
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
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 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
