The thin deep fascia of the dorsum of the hand is lost over the expansions ot the extensor tendons on the fingers. Between the metacarpal bones a strong layer of fascia covers and gives attachment to the interossei muscles. Aponeurosis Palmaris.—The palmar aponeurosis is of considerable import- In the centre of the palm it forms a thick triangular membrane, the apex of which joins the distal edge of the trans- verse carpal ligament, and more superfici- ally receives the insertion of the tendon of the palmaris longus muscle. The fascia separates below into four slips, one for each finger, con- nected together by transverse fibres, and form- ing beneath the webs of the fingers the superficial trans- verse metacarpal ligament (fasci- culi transversi). Beyond this each slip separ- ates into two parts, to be con- nected to the sides of the metacarpo- phalangeal joints and the first phalanx of the medial four digits. In the cleft between the two halves of each slip the digital sheath is attached and extends distally on to the finger. The lateral borders of this triangular central portion of the palmar aponeurosis are continuous with thin layers of deep fascia, which cover and envelop the muscles of the thenar and hypothenar eminences. The medial border gives origin to the palmaris brevis muscle (p. 382). The digital sheaths (vaginse mucosae) are tubular envelopes extending along the palmar aspect of th
