Thigh Objective 15 Identify various surface features of the The femur is the only bone of the thigh, but there are three buttock and lower extremity by observation or palpation. The anterior group of muscles, referred Objective 16 Discuss the clinical importance of the buttock, to as the quadriceps femoris, extends the knee joint when it is femoral triangle, popliteal fossa, ankle, and arches of the foot. The medial muscles are the adductors, and when contracted they draw the thigh medially. The “ham- strings” are positioned on the posterior aspect of the thigh Surface Anatomy (see fig. The tendinous Buttock attachments of the hamstrings can be palpated along the poste- rior aspect of the knee joint when it is flexed. The hamstrings or The superior borders of the buttocks, or gluteal region, are formed their attachments are often injured in athletic competition. It can be seen as a the natal cleft (gluteal cleft) extends vertically to separate the depression inferior to the location of the inguinal ligament on buttocks into two prominences, each formed by pads of fat and the anteromedial surface in the upper part of the thigh (see by the massive gluteal muscles. The major vessels of the lower extremity, as well as pated in the lower portion of each buttock. Hernias are frequent in the ischial tuberosities support the weight of the body. More important; the femoral triangle serves as an arte- standing, these processes are covered by the gluteal muscles. The inferior border of The greater trochanter of the femur can be palpated on the the gluteus maximus muscle forms the fold of the buttock. At the knee, the lateral and medial condyles of the femur and tibia can be buttock: O.

It also changes the slope of the venous return curve for reasons not discussed here order uniphyl cr 400mg free shipping. The unique right atrial pressure at which tion of the venous return curve for right atrial pressures venous return is equal to cardiac output is now 8 mm Hg. In this example, when right Other factors that influence the relationship between car- atrial pressure reaches 7 mm Hg, venous return stops.
