It is attached laterally to the navicular and large multangular; medially to the pisiform and os hamatum; and it forms a membranous arch binding down in the hollow of the carpus the flexor tendons of the fingers, and the median nerve. It is divided into two compartments, the larger accommodating the tendons of the flexors of the digits and the median nerve, the smaller (placed laterally) containing the tendon of the flexor carpi radialis. There are three synovial membranes in these compartments:
. Cunningham's Text-book of anatomy. Anatomy. FASCIA AND MUSCLES OF THE FOKEAEM AKD HAND. 383 hand. It is attached laterally to the navicular and large multangular; medially to the pisiform and os hamatum; and it forms a membranous arch binding down in the hollow of the carpus the flexor tendons of the fingers, and the median nerve. It is divided into two compartments, the larger accommodating the tendons of the flexors of the digits and the median nerve, the smaller (placed laterally) containing the tendon of the flexor carpi radialis. There are three synovial membranes in these compartments: one for the flexor carpi radialis tendon, and two others, which often communicate together, enveloping the tendon of the flexor pollicis longus and the flexor tendons of the fingers respectively. The surface of the liga- ment is crossed by the palmar branches of the median and ulnar nerves ; by the tendon of the palmaris longus muscle, which is attached to its sur- face; and by the ulnar artery and nerve, which are again bridged over and pro- tected by a band of fibrous tissue, called the volar carpal liga- ment, which passes from the pisiform bone and the super- ficial fascia to the surface of the trans- verse carpal ligament. To the distal border of the ligament are attached the palmar aponeurosis in the centre, and the super- ficial muscles of the thumb and the mus- cles of the little finger on each side. Ligament um Carpi Dorsale.— The dorsal carpal ligament ( pos- terior annular liga- ment) is placed at a more proximal level than the transverse carpal ligament. It consists of an oblique band of fibres about an inch broad, continuous proximally and distally with the deep fascia of the forearm and hand. It is attached laterally to the lateral side of the distal end of the radius, and medially to the distal end of the ulna (styloid process), the carpus, and the ulnar collateral ligament of the wrist. It is crossed by veins, by the superficial ramus of the radial nerve,
