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 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 is the pectineus muscle used for?
The pectineus muscle functions to flex and adduct the thigh at the hip joint when it contracts. There are various stretches that can aid in stretching the pectineus muscle and these include the lateral lunge, adductor stretch, and hurdle stretch.
Are spiral line and pectineal line the same?
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 [15].
What does pectineal mean?
adj. Of or relating to the pubic bone. Relating to any comblike structure.
Why is the pectinate line important?
Blood Supply and Lymphatics. 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.
What is the pubic crest?
Medical Definition of pubic crest
: the border of a pubis between its pubic tubercle and the pubic symphysis.
How do you activate pectineus?
Conclusion: The pectineus was highly activated during hip flexion exercises and moderately activated during exercises requiring rotational hip stabilization in either direction, rather than with internal hip rotation only.
Can u pull your pectineus?
The pectineus muscle, a flat, quadrangular muscle located in the middle of the thigh, helps to flex or move your leg towards your body. Running, skating, kicking a soccer ball, playing basketball, or exercising with fatigued muscles can strain or pull this muscle, resulting in a painful injury.
How do you isolate pectineus?
Bend your raised leg slowly, causing you to lunge forward, while keeping your torso straight. Push your hips slightly forward and hold the stretch for at least two seconds, but you can hold for longer as your strength increases. Perform ten repetitions on one side, then repeat with the other leg.
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 the intertrochanteric crest?
The intertrochanteric crest, not to be confused with the intertrochanteric line, is a ridge on the femur located at the posterior aspect of the junction between the femoral neck and shaft, traversing between the greater and lesser trochanters. It is the posterior point of attachment for the joint capsule of the hip.
What does Pectineus mean in medicine?
Medical Definition of pectineus
: a flat quadrangular muscle of the upper front and inner aspect of the thigh that arises mostly from the iliopectineal line of the pubis and is inserted along the pectineal line of the femur.
What is Cooper’s ligament inguinal?
The Cooper’s ligament lines the superior border of the pubic bone between the pubic spine and the iliopectineal eminence. This ligament joins the inguinal ligament medially where it forms the lacunar ligament of Gimbernat but diverges laterally from it when runs in a much deeper position.
