III. Anterior Muscles of the Thigh

The quadriceps femoris resembles that of the horse; the vastus intermedius is more clearly separable, and consists of two parts. Bursæ occur under the insertions of the internal and external vasti, and often under the end of the biceps in the adult.

The articularis genu or subcrureus is a small muscle which lies under the lower part of the vastus intermedius, and is inserted on the suprapatellar cul-de-sac of the synovial membrane.

The capsularis is absent.
