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.

The Subtalar Joints and Ligament Diagram

Subtalar joint (talocalcaneal) allows inversion/eversion; ligaments: interosseous talocalcaneal (strongest, in sinus tarsi), medial/lateral talocalcaneal, cervical (stabilizes). It works with transverse tarsal joint for foot flexibility.
