Anatomy Origin: Inferior aspect of lateral condyle of tibia, upper three-fourths of the anterior surface of the interosseous membrane and the anterior intermuscular septum. Insertion: The extensor digitorum longus tendon divides into four slips deep to the inferior extensor retinaculum. The four slips insert onto the dorsal aspects of the middle and distal phalanges of

Anatomy Origin: Anterolateral part of the superior surface of calcaneus and inferior extensor retinaculum. Insertion: Lateral aspect of the extensor digitorum longus tendons of 2nd, 3rd and 4th toes. Key relations: Runs anteromedially across the foot and can be palpated inferomedially to the lateral malleolus on the dorsum of the foot. Functions Extends the 2nd,

Anatomy Course Arises after the bifurcation of the common carotid artery at the level of the thyroid. As it rises it takes a curved path and rapidly diminishes in size due to the amount of collaterals it gives off. It eventually ends up behind the neck of the mandible where it gives off its terminal

Anatomy Course Begin at the sides of the digits beside their counterpart arteries and drain into the dorsal metacarpal venous network on the back of the hand. Drain Drains the digits of the hand. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Course Branches of the superficial radial nerve near its termination. Supply Lateral aspect of the middle finger as well as the medial aspect of the index finger. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Course Branches of the dorsal metacarpal arteries. They enter the distal portions of the digits on the posterior surface of the phalanges. Anastamoses exist between them and the proper palmar digital arteries. The arteries are dorsal to the digital nerves. Supply Supply the lateral, medial and dorsal aspects of the digits.

Anatomy Attaches from the dorsal margin of the cuboid bone to the lateral dorsal margin of the lateral cuneiform bone of the foot. Functions One of the dorsal ligaments of the foot. It stabilizes the dorsal surface of the foot. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Strongest and most distinct carpometacarpal ligaments connecting the carpal and metacarpal bones on their dorsal surface of the hand. The second metacarpal bone receives two fibrous bands from the trapezoid and trapezium bone. The third metacarpal receives two bands, one each from the trapezium and capitate bones. The fourth two, one each from the

Anatomy A thin but broad fibrous bundle, which passes between the adjacent surfaces of the calcaneus and cuboid, on the dorsal surface of the joint. Functions Provides support to the subtalar joint between the calcaneus and cuboid. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Motion The distal tibiofibular joint is a syndemosis type fibrous joint. The medial surface of the inferior end of the fibula articulates with the fibular notch on the lateral side of the tibia. It allows very little movement but slight movement accommodates the talus during dorsiflexion of the foot. Stability Ligaments stabilizing the joint include:
