Anatomy Course First dorsal metatarsal artery is a direct branch of the dorsalis pedis artery. The second, third and fourth metatarsal arteries originate from the arcuate artery. Supply Together they supply the digits of the foot. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy A thin leaf shaped cartilage situated at the inlet of the larynx. It is formed from yellow elastic fibrocartilage. It lies posterior to the root of the tongue and the hyoid bone. Its superior end is free, its inferior end is tapered and attaches internally to below the thyroid notch via the thyroepiglottic ligament.

Anatomy Course Arise from the dorsal digital veins, which form three dorsal metacarpal veins. These travel briefly before creating a complex network on the dorsum of the hand. Drain Drain the dorsum of the hand. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Epididymis (head – receives spermatozoa, body, tail – reabsorbs fluids and concentrates sperm) is a single coiled tube, 20-24 feet long, enveloping/investing/covering the back and top of the testis, its head continuous with and receiving immature sperm (can’t swim or fertilise) from efferent ducts at back of testis, passing them on (mature, typically after

Anatomy Thick bands of connective tissue attaching from the bases of the two to five metacarpal bones. Functions By linking metacarpal bones two to five, they help to form the skeletal framework of the palm. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Layer of tough, dense, fibrous tissue that covers the upper portion of the cranium. Attaches posterior to occipitalis, anteriorly to frontalis, and laterally to auriculares anterior and superior. Posteriorly and laterally, its fibers are continued to the external occipital protuberance and zygomatic arch, respectively. Dorsally, it is firmly connected to the skin by the

Anatomy Origin: Bipennate muscles that arise by two heads from adjacent sides of posterior aspect of the metacarpals. Insertion: Extensor hood and base of proximal phalanges of the index, middle and ring fingers. (It is the middle digit that has two dorsal interossei inserting onto it.) Key relations: The radial artery (after passing between the

Anatomy The joint capsule attaches to the articular margins of the ulna, radius and humerus. It attaches to the margins of the olecranon, coronoid process and radial fossae. Distally, it blends with the annular ligament. The capsule is thinner anteriorly and posteriorly. Functions The capsule supplies static stability to the elbow joint. Interested in taking

Anatomy Origin: Sides of the adjacent metatarsals. Insertion: Bases of proximal phalanges of 2nd, 3rd and 4th toes and dorsal expansions of the extensor digitorum longus tendons. Key relations: The dorsal interossei lie dorsal to the plantar interossei and together they form the fourth layer of the plantar muscles of the foot. Also, see view

Anatomy Course On the dorsum of the foot they receive the intercapitular veins. They travel briefly to join the plantar cutaneous venous arch. Drain Drains the dorsal surface of the digits of the foot. Interested in taking our award-winning Pocket Anatomy app for a test drive?
