The muscle arises by a short flat tendon from the pectineal process.
The pectineal process is an anterolaterally directed projection of the ventrolateral edge of the ilium anteroventral to the acetabulum.
The femoral notch of the ilium is a shallow notch in the ventrolateral edge of the ilium approximately halfway between the last rib and the pectineal process.
The capsule is torn farther forward than in the other varieties, and the head rests on the horizontal ramus of the pubes against the ilio-pectineal line.
The pelvis is wider and lower than in Dinornis, with the lower border of the postacetabular portion of the ilium descending as a sharp ridge much below the level of the sacral ribs, and without any distinct pectineal process.
The pelvis approximates to that of the Apterygidae, but the pectineal process of the pubis is less developed, and the ischium and pubis may be longer and more slender.
The pubis has a small pectineal process; and the ventral aspect of the true and postacetabular vertebrae is very broad and much flattened.
The pelvis is much narrower than in Dinornis, with the ventral surface of the postacetabular sacrals ridged and narrower, and a more developed pectineal process to the pubis.
In Orycteropus however the ischium does not become united to the vertebral column, and the pubis generally has a strongly developed pectineal process.
The pubis has a strongly developed pectineal process, which occasionally unites with a process from the ilium enclosing a large pre-acetabular foramen.
The ischium often has a well-marked tuberosity and in Kangaroos the pubis bears a prominent pectineal process on its anterior border close to the acetabulum.
In many birds the pubis is drawn out in front into the pectineal process, this is specially large in Apteryx (fig.
A curious feature in the osteology of the genus, and indeed of the sub-family, is the fact that the ileo-pectineal process is connected with the ilium by a bony bridge; this arrangement is unique among mammals.
The pubis consists of a short anterior portion (spina pubica or pectineal process, homologous with the prepubic process of Dinosaurs) and the long and slender pubis proper (equivalent to the processus lateralis pubis of most reptiles).
The pectineal process is variable; it may grow entirely from the pubis, or both pubis and ilium partake of its formation, or lastly its pubic portion may be lost and the process is entirely formed by the ilium.
Gimbernat's ligament consists of tendinous fibres which connect the inner end of the femoral arch with the pectinealridge of the os pubis.
These divide into two bands, which, gradually widening from each other as they proceed inwards, become inserted, the upper one into the symphysis pubis, the lower into the spine and pectineal ridge of this bone.
Gimbernat's ligament, 8; and the conjoined tendon, 4; where this is inserted with the ligament into the pectineal ridge.
This tendon is inserted with the ligament into the pectineal ridge.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "pectineal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
