Course of the Superior Epigastric Artery Diagram

The superior epigastric artery (from internal thoracic) descends in rectus sheath, anastomoses with inferior epigastric, supplying rectus abdominis and anterior abdominal wall. It forms part of Hesselbach’s triangle boundary.

Layers of the Thoracolumbar Fascia Diagram

Thoracolumbar fascia layers: anterior (psoas/quadratus lumborum), middle (between erector spinae/quadratus), posterior (covering erector spinae). They enclose paraspinal muscles, provide attachment for obliques/transversus.

Hip Add Abd Diagram

The Hip Add Abd diagram (likely adduction/abduction) illustrates hip movements: adductors (magnus, longus, brevis, gracilis, pectineus) pulling the thigh medially, abductors (gluteus medius/minimus, tensor fasciae latae) moving it laterally. It…

Heart Wall

The heart wall has three distinct layers working together to pump blood tirelessly. The inner endocardium is smooth endothelium over connective tissue, preventing clots and providing a low-friction surface. The…

Parts of the Parietal Pleura Diagram

Parts of parietal pleura: costal (chest wall), diaphragmatic (diaphragm), mediastinal (mediastinum), cervical (apex above first rib). Reflections form recesses (costodiaphragmatic deepest); fluid accumulates there in effusion.

Cutaneous Innervation to the Upper Limb Diagram

Cutaneous innervation of the upper limb includes dermatomes from C5-T1: axillary (regimental badge), musculocutaneous (lateral forearm), median (palm/thumb-index-middle), ulnar (little/ring), radial (dorsal hand). Overlap helps in nerve lesion mapping.

CT Scan Head Scanning Diagram

CT head scanning uses X-rays in axial slices, bone windows for skull fractures, soft tissue windows for hemorrhage/infarct/edema. Contrast enhances vessels/tumors; it’s fast for trauma/stroke evaluation.

Ligaments of the Cervical Spine Diagram

Cervical spine ligaments: anterior/posterior longitudinal (along vertebral bodies), ligamentum flavum (laminae), interspinous/supraspinous (spinous processes), nuchal (posterior). They stabilize flexion/extension, limit excessive motion.

First Layer of Plantar Muscles Diagram

First layer of plantar muscles: abductor hallucis (medial), flexor digitorum brevis (central), abductor digiti minimi (lateral). They arise from calcaneal tuberosity, support medial/longitudinal arch; medial/lateral plantar nerves supply.
