Over the proximal phalanx, the superficialis tendon splits into two halves, which pass around the profundus tendon. We are unable to receive your feedback at this time. The lateral bands join together over the middle phalanx and insert here, on the base of the distal phalanx. The other two we’ll see in the next section. It runs obliquely, from this ridge on the radius, to the ulnar styloid, the triquetrum, and the hamate. Extensor pollicis brevis extends only the MP joint. The flat part, or blade, is roughly triangular with an upper border, a lateral border, and a medial border.

The radial one arises from the lateral epicondyle. In the course of the brachial plexus, the nerves that supply the shoulder region are given off.

The head of the ulna has a rounded articular surface. Again the palmar aponeurosis has been acland anatomy dvd. The three posterior divisions all unite, as we’ll see in a minute. It starts here, under the tail end of trapezius, at T7, and goes all the way down to the sacrum, and out onto the posterior iliac crest.
Because of the rotation that occurs, the tip of the thumb ends up pointing toward the fingers.

The two collateral ligaments hold the bones together in radial abduction and ulnar abduction, and the radio-carpal ligaments hold them together in flexion and extension. Here are the five roots of the brachial plexus: For students, Acland’s DVD Atlas is a time-saving aid to anqtomy learning, an effective way to relearn anatomy for clinical rotations, and a time-efficient tool for review.
Here are the divided ends of the two first acland anatomy dvd and here’s the divided end of anatoym sternum. Between them these supply extensor carpi ulnaris, extensor digitorum and the other two finger extensors, and these three long thumb muscles, abductor pollicis longus, and extensor acland anatomy dvd brevis, and longus.

On the left side, the subclavian artery arises directly from the arch of the aorta. Rotation which moves the front of the acland anatomy dvd towards the body, is internal rotation. The distal row of carpal bones articulates with the proximal row here, to form the midcarpal joint. Lastly we’ll look at the principal blood vessels and nerves in the region. We’ll look at the main components of the brachial plexus first, then at the local branches.
The one on the front is subscapularis. At each joint acland anatomy dvd sheath is attached to the edge of the palmar plate. Its radial head arises from this long oblique line on the radius. Just anatomu the flexor tendons zcland from the carpal tunnel, the four profundus tendons give rise to these four intrinsic muscles, the lumbricals. Halfway down the arm they diverge. It passes under the acromion and inserts here, on the greater tubercle.
It usually ends by anastomosing with the superficial branch of the radial artery, forming a loop called the superficial palmar arch. Because it’s between two tubercles, the bicipital groove is also known as the inter-tubercular groove.
Azal Nir added it Jul 28, Three names for one artery: It sits in front of the other CMC joints, and at an angle to them. In acland anatomy dvd back under the scapula, and it’s inserted all the way back here, along the medial border of the scapula. It acland anatomy dvd from the medial epicondyle, like the other two. The base of the adjoining phalanx has a aclaand curve to it. To get to its insertion, the latissimus tendon has to spiral around teres major. Together with other veins from the shoulder region, it joins the main vein of the upper extremity, the subclavian vein.
It qcland just beneath the palmar aponeurosis, which has been removed here.
If you want to test yourself, turn off the sound. Just as the subclavian vein reaches the medial border of the first rib, which is here, it’s joined from above by the main vein from the head and neck, the internal jugular vein.
Refresh and try again.
