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. Pectineal line (pubis) Female pelvis. Pectineal line in purple slightly lateral to midline of bottom of central opening.
What attaches to Pectineal line of pubis?
Pectineus is a short quadrangular muscle extending from the pubis to the area just below the lesser trochanter of femur. It has the most superior attachment of all the thigh adductors, originating from the pectineal line of pubis on the superior pubic ramus.
What does the pectineal line separate?
The pectinate line (dentate line) is a line which divides the upper two-thirds and lower third of the anal canal. Developmentally, this line represents the hindgut-proctodeum junction.
What muscles attach to pubic Rami?
gracilis muscle and adductor brevis muscle at the external surface of the body of pubis and its inferior ramus.
Where is the ischial?
The ischium (Latin: os ischii) is a paired bone of the pelvis that forms the lower and back part of the hip bone, as well as the posterior and inferior boundary of the obturator foramen.
Where is the pectineal line of femur?
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.
What is linea aspera?
The linea aspera is a longitudinally-oriented ridge on the posterior aspect of the femur to which several muscles of the thigh attach. It is comprised of medial and lateral lips which diverge at both its superior and inferior ends.
What is Cooper’s ligament inguinal?
The pectineal ligament (somewhat confusingly also known as the inguinal ligament of Cooper) is an extension of the lacunar ligament that runs along the pectineal line of the pubis (also known as the pecten pubis).
Why pectinate line is called watershed line?
The pectinate line is called the watershed line because it separates the two entirely different parts of the anal canal (in terms of development, nerve supply, blood supply and lymphatic drainage).
What is pectinate line?
The inferior limit of the anal valves forms an irregular line, the ‘pectinate line,’ that indicates the junction of the superior part of the anal canal (visceral: derived from the embryonic hindgut), and the inferior part (somatic: derived from the embryonic proctodeum).
Why is the pectinate line important?
The pectinate line is an important anatomic landmark, as it is where the blood supply, lymphatics, and nerves differ based on being above or below the pectinate line.
Why does my pubic bone hurt when I walk?
Osteitis pubis
Like pubic symphysis dysfunction, osteitis pubis also affects the area of the pubic symphysis and surrounding tissues. It can lead to pelvic soreness or pain that can get worse with physical activity. Osteitis pubis is an overuse injury.

Where is the inferior pubic ramus located?
The inferior pubic ramus is a part of the pelvis and is thin and flat. It passes laterally and downward from the medial end of the superior ramus; it becomes narrower as it descends and joins with the inferior ramus of the ischium below the obturator foramen.
Where is the Ischiopubic Ramus?
Ischiopubic ramus is the region between “3” and “4c”. Right hip bone. External surface. It forms the inferior border of the obturator foramen and serves as part of the origin for the obturator internus and externus muscles.
Where is the superior pubic ramus?
The superior pubic ramus is one third of the pubic bone. It forms a portion of the obturator foramen and extends from the body to the median plane where it articulates with its counterpart from the opposite side. It is described in two portions, which are a medial flattened part and a narrow lateral prismoid portion.
Where is the pectineal line of femur?
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.
