MUSCULAR SYSTEM. 153 



timately united with the psoas parvus, as it runs forward side 

 by side with it, that it is somewhat difficult to make out the 

 kmibar attachments distinctly. The interior termination consists 

 of a broad, flat, glistening tendon, which (in union with the 

 tendon of the gracilis) expands into an aponeurosis, spread- 

 ing over the entire inner side of the stifle joint. 



Action. — To assist in bending the leg ; and, in the flexed po- 

 sition, to give the limb a rotatory motion inwards. 



G R A ci LIS. — Sub-pubio-tibialis. 



Situation. — Superficial, on the internal part of the thigh. 



Figure. — Quadrilateral, broad, thin, flattened. 



Attachment. — Superiorly, to the symphysis pubis, extending 

 as low down as the ischium ; inferiorly, (along with the sar- 

 torius) to the supero-internal part of the tibia, and the internal 

 condyle of the femoral bone. 



Relations. — Along its antero-internal border, with the pec- 

 tineus and sartorius ; on its inner side, with the adductors ; on 

 its outer side, with the faschia lata and skin. 



Structure. — The pubal attachment is tendinous and fleshy : 

 inferiorly, it ends in a broad aponeurosis, which, forming a union 

 with the tendon of the sartorius, expands upon the inner side 

 of the stifle, and is continued upon the leg into the tibial 

 faschia. 



Action. — To bend the leg, and (when flexed) to rotate it 

 inwards. 



PECTIN Eus. — Super-pubio-femoralis. 



Situation. — Inner, upper, and anterior part of the haunch. 



Form. — Fusiform; thickest in the middle; upper extremity 

 flattened. 



Attachment. — Superiorly, to the brim and anterior surface of 

 the pubes, near the symphysis ; and to the infero-anterior part 

 of the same bone, near the acetabulum. Inferiorly, to a long 

 ridge extending from the trochanter internus. 



Relations. — On the outer side, with the sartorius ; anteriorly 

 and internally, with the gracilis ; posteriorly, with the ad- 

 ductors. 



Structure. — The superior attachment consists of a bifurcated 

 tendon ; the inferior is both tendinous and fleshy. Its fleshy 

 belly is striped with aponeurosis. 



Actioyi. — To flex the haunch, and at the same time adduct it.
