It blends,distally, with the metacarpophalangeal ligaments and, proximallywith the fascia of the interosseous muscles. THE METACARPOPHALANGEAL ARTICULATIONS These joints are of the condyloid variety. A capsule surrounds each joint and this is strengthened dorsallyby the expansions of the tendons of the m. extensor digitorumcommunis. The ventral, or volar ligament {lig. vaginale) is thick, strong andgrooved for the flexor tendons. The collateral ligaments {ligg. collateralia) are cord-like thickeningsof the lateral parts of the capsule. Movements.—Flexion, extension and some abduction, adductionand circumduction. THE SACROILIAC ARTICULATION 129. ARTICULATIONS OF THE PHALANGES (ARTICULATIOI^IS DIGITORUM MANUS) These joints are of the ginglymus variety. A capsule is present and is strengthened by a ventral, or volar,and two collateral ligaments arranged simOarlyto those in the preceding articulations. Each of these joints has a complete sy-novial membrane lining the joint cavity. Movements.—Flexion and extension. THE ARTICULATIONS OF THE INFERIOR EX-TREMITY (PELVIS APPENDAGE) This appendage comprises one-half of thepelvic girdle and the appendage pelvic girdle comprises the two ossacoxae (innominate bones), that articulatewith each other ventrally at the symphysispubis, and with the sacrum dorsally. Uponeach side the girdle articulates with theproximal extremity of the femur. Accessoryligaments are also present. THE SACROILIAC ARTICULATION (ARTICU-LATIO SACROILIACA) This articulation is of the amphiarthrodialvariety. A joint cavity is barely preceptible. A capsule is formed by the following liga
