This has its origin and insertion at points directly opposite to those of the psoas muscle— and forms the nates or but- tock. The fibers of this mus- cle are the coarsest of any in the whole body, showing that they are designed for strength and not celerity of motion. Besides the movement already mentioned, this muscle is of great value when the leg is made firm by keeping the body in an upright position, or raising the body upon the thighs when it is bent forward. 254. Muscles of the Thigh.—The leg (Tibia) is moved upon the thigh (Fe- mur) by the conjoint action of four muscles. These have their origin about the head of the femur, and the lower por- tion of the innominatum, and all unite into one tendon which is inserted upon the tubercle, or process of the.

What movements are effected by it ? 253. What muscle produces motion in a con- trary direction to the psoas muscle ? What is said of the size of the fibers of the Gluteus ? 254. How many muscles act to extend the tibia or the femur?.
