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?

Motion The elbow joint is a uniaxial compound synovial hinge joint. The elbow joint actually includes 2 joints the humeroulnar joint and the humeroradial joint. The capitulum of the humerus articulates with the head of the radius, and the trochlea of the humerus articulates with the trochlear notch of the ulna. Together these articulations make

Anatomy 15-20 muscular ducts which connect rete testis to epididymis, accounting for 1/3 volume head of epididymis, concentrating spermatozoa by water reabsorption and moving them on. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy The dura mater is the strong, thick, outermost layer of the meninges attached to the periosteum of the skull except where it runs long the skull base or is reflected along the skull vault. Venous sinuses run inside spaces within the dura mater created by separation of the dura mater from the periosteum at
