What part of the os is the Coxae?
The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis….

What is the pectineal line?
The pectineal line of the pubis (also pecten pubis) is a ridge on the superior ramus of the pubic bone. It forms part of the pelvic brim. Lying across from the pectineal line are fibers of the pectineal ligament, and the proximal origin of the pectineus muscle.
What are the 3 parts of the os coxae?
The os coxa is comprised of three parts : the ilium, ischium, and pubis.
What is os coxae?
os coxae. one of three bones that form the pelvis. paired; the os coxae forms the lateral part of the pelvis; it is formed by three fused bones: ischium, ilium & pubis; also known as the innominate bone. acetabulum.
Is pectineal line same as spiral line?
While the spiral line, which provides the origin for the vastus medialis muscle, runs medially towards the lesser trochanter, the pectineal line, marking the insertion of the pectineus muscle, is located lateral and superior to it .
What attaches on the pectineal line?
Right femur. Posterior surface. On the posterior surface of the femur, the intermediate ridge or pectineal line is continued to the base of the lesser trochanter and gives attachment to the pectineus muscle.
Is os coxae axial or appendicular?
The pelvic girdle is formed by the paired os coxae (coxal bones). Together with the sacrum and coccyx of the axial skeleton, this group of bones forms the bony pelvis.
Where is the iliopectineal line?
The iliopectineal line is a curvilinear line running from the iliosacral joint along the medial border of the iliac wing and the superior border of the superior pubic bone up to the symphysis and delineates the inner margin of the pelvic ring 1-4.
Where is the right os coxae?
The hip bone (os coxae) is the complex-shaped bony structure formed after the fusion (synostosis) of three bones: ilium, ischium, and the pubis, that usually occurs before the age of 20*. The two hip bones are the major structural component of the pelvis.
What does the os coxae articulate with?
In the adult, the pelvis (os coxae) is formed by the fusion of three bones: ilium, ischium, and pubis (Figure 6-1A and B). The union of these three bones occurs at the acetabulum. The paired os coxae articulate posteriorly with the sacrum and anteriorly with the pubic symphysis.
