The subphrenic and subhepatic recesses are peritoneal spaces situated beneath the diaphragm and liver, respectively. The subphrenic recess lies between the diaphragm and anterior surface of the liver, while the subhepatic space is located between the liver and transverse colon.

The cubital fossa is an anterior elbow region bounded by the brachioradialis, pronator teres, and an imaginary line between epicondyles. It contains the brachial artery, median nerve, radial nerve, and tendon of biceps brachii. Knowledge of its surface anatomy is View Diagram Surface Anatomy of the Cubital Fossa
The tongue develops from multiple pharyngeal arches, forming anterior and posterior regions with distinct innervation. Muscular and epithelial differentiation gives rise to intrinsic and extrinsic muscles, taste buds, and sensory components. Understanding tongue development is critical in embryology, pediatric surgery, View Diagram Development of the Tongue
The oral cavity is divided into the vestibule and the oral cavity proper. The vestibule lies between the lips and cheeks externally and the teeth and gums internally, while the oral cavity proper is bounded by the teeth and communicates View Diagram Divisions of the Oral Cavity
The ventricular system consists of the lateral ventricles, third ventricle, cerebral aqueduct, and fourth ventricle. These cavities contain cerebrospinal fluid, which cushions and nourishes the brain. Surface landmarks help approximate their location for clinical procedures.
The development of the nose and face begins in early embryogenesis with the formation of nasal placodes, frontonasal prominence, and maxillary and mandibular prominences. These structures fuse to create the external nose, nasal cavity, and facial contours. Abnormal fusion can View Diagram Development of the Nose and Face
Inversion and eversion are side-to-side movements of the foot that occur mainly at the subtalar joint. This anatomy diagram of ankle inversion and eversion demonstrates how inversion turns the sole inward, while eversion turns it outward. It highlights the role View Diagram Ankle Inv Ev
The surface anatomy of the femoral triangle shows its boundaries: inguinal ligament, sartorius, and adductor longus, containing the femoral nerve, artery, and vein. Knowledge of this region is essential for surgeons, radiologists, and medical students performing vascular access, catheterization, or View Diagram Surface Anatomy of the Femoral Triangle
The sagittal section of the female pelvis reveals the anatomical relations of the internal reproductive tract, including the uterus, cervix, vagina, bladder, and rectum. The uterus lies anterior to the rectum and posterior to the bladder, with the broad ligaments View Diagram Sagittal Section of the Female Pelvis Anatomical Relations of the Internal Reproductive Tract
The right atrium and interatrial septum form the heartÂ’s venous receiving chamber, collecting deoxygenated blood from the superior and inferior vena cava and coronary sinus. The interatrial septum separates the right atrium from the left atrium, featuring the fossa ovalis View Diagram Right Atrium and Interatrial Septum
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
