Posterior . 
Situation . —Postero-externai side of the haunch and thigh ; 
where, being superficial, its course is well marked in the living 
animal. 
Attachment .—Superiorly, to the lateral and posterior parts of 
the spine of the sacrum, and some of the upper pieces of the 
os coccygis; to the sacro-sc-iatic ligaments ; to the tuberosity of 
the ischium, and to the faschia lata. Inferiorly, it is split into 
two portions, one of which is attached to the patella and its 
external ligament; the other (through the intervention of an 
aponeurotic expansion) to the ridge upon the upper part oi the 
tibia, and to the faschia covering the leg. 
Relation#. —Externally, with the faschia and skin ; internally 
and superiorly, w ith the gluteus maximus ; internally and inferi- 
orly, with the gastrocnemii; anteriorly, with the external tro¬ 
chanters, major and minor, and with the body of the femoral 
bone ; posteriorly, with the tuberosity of the ischium and semi- 
tudinosus. 
Structure .—Heshy; surfaces, aponeurotic. Attached by a 
broad flat tendon to the tuberosity of the ischium; by a more 
slender one to the trochanter minor externus; by a broad, flat¬ 
tened, and thick tendon, invested by some few fleshy fibres, to 
the patella and its ligament; and to the tibia and tibial faschia 
by a broad expanded aponeurosis. The inferior division is, at its 
upper part, united with the next muscle by intermixture of fleshy 
fibres. -
