Anatomy Articulates up with capitate, out with index metacarpal, in with ring metacarpal (1st thumb, 2nd index, 3rd middle, 4th ring, 5th little), down with proximal phalanx (3rd MCP). Clinical MCP is a knuckle (4 each hand, as thumb MCP not ordinarily included). Common sites for fractures and other fist injuries. Interested in taking our

Motion These are the joints lying between the distal heads of the metacarpals and the proximal phalanges of the digits. They are synovial condylar joints. They have a wide range of motion, including: flexion, extension, abduction and adduction. The flexion component of these is the most extensive, commonly terminated by a grasped object. Stability Articular

Anatomy Thickest shortest metatarsal, on medial edge foot behind/proximal to big toe, articulates proximally with medial (1st) cuneiform, sometimes out (from base) with 2nd metatarsal, distally with 1st proximal phalanx and below (from head) with sesamoid bones. Tibialis anterior, peroneus longus attached. Vignette Metatarsal bones are prismoid, thicker at proximal end (base/ posterior extremity/tarsal end),

Anatomy Articulates proximally with lateral (3rd) cuneiform, out with 4th and in with 2nd metatarsals (from base), distally with 2nd proximal phalanx. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Supply Motor supply to the quadriceps femoris as well as many other muscles in the thigh. Cutaneous supply of the anterior and lateral thigh. Anatomy There are two anterior cutaneous branches of the femoral nerve: Intermediate femoral cutaneous nerve and Medial femoral cutaneous nerve. Course The femoral nerve is the largest branch of the lumbar

Anatomy Course A branch of the common tibular nerve. It runs down the posteromedial aspect of the calf. Clinical Damage to the nerve will result in a loss of sensation in the skin on the anterior and posterior portions of the medial calf. Supply Provides sensory innervation to the skin on some of the anterior

Anatomy Course Originates from the deep femoral artery. It first passes between the iliopsoas and pectineus muscles, and then passes between the obturator externus and adductor brevis muscles. Finally, it passes above the margin of the adductor magnus to travel medially around the neck of the femur. It then divides into two major branches deep

Anatomy Course Begins at the neck of the femur and medially travels above the margin of the adductor magnus. It passes between the obturator externus and adductor brevis muscles, and then between the iliopsoas and pectineus muscle. It drains into the deep femoral vein. Drain Drains the head and neck of the femur. Interested in

Anatomy Tarsal bone, wedge-shaped, largest of the cuneiforms, articulates forward with 1st (big toe) and 2nd metatarsals, laterally/out with middle/intermediate cuneiform, proximally with navicular. Vignette Hindfoot; talus, calcaneus. Midfoot; cuboid, navicular, cuneiforms (medial, intermediate, lateral). Forefoot; metatarsals, phalanges.
