What is the origin and insertion of the Pectineus?
Pectineus is a flat muscle found in the superomedial part of the anterior thigh….Pectineus muscle.
| Origin | Superior pubic ramus (pectineal line of pubis) |
|---|---|
| Insertion | Pectineal line of femur, linea aspera of femur |
What is the insertion of the Pectineus muscle?
Pectineus muscle inserts into the posterior surface of femur, along the pectineal line and proximal part of linea aspera.
What is the main function of the Pectineus muscle?
The pectineus muscle is a small muscle locates in the mid-thigh of the leg. Its physiologic role is in the flexing and adducting (drawing inward toward the body) of the thigh. Due to its location and function, it is classified as a pelvic muscle.
What is the origin and insertion of the adductors?
The adductors originate on the pubis and ischium bones and insert mainly on the medial posterior surface of the femur….Structure.
| Muscle | Adductor longus |
|---|---|
| Origin | Front side of the pubic bone under the pubic tubercle |
| Insertion | Medial ridge of linea aspera |
| innervation | Obturator nerve (L2-L4) |
Can you feel the pectineus muscle?
The most common symptoms of an injured pectineus muscle are pain, bruising, swelling, tenderness, and stiffness. Pain in the front hip area can mean that you may have strained the primary hip flexor muscles or the hip adductor muscles, or a combination of the two.
What is the origin of the adductor muscles?
Adductor longus muscle
| Origin | Body of pubis, inferior to pubic crest and lateral to the pubic symphysis |
|---|---|
| Insertion | Middle third of linea aspera of femur (medial lip) |
| Action | Hip joint: Thigh flexion, Thigh adduction, Thigh external rotation; Pelvis stabilization |
| Innervation | Obturator nerve (L2-L4) |
What is the origin of adductor brevis?
| Adductor brevis muscle | |
|---|---|
| Origin | anterior surface of the inferior ramus and body of the pubis |
| Insertion | the lesser trochanter and linea aspera of the femur |
| Artery | deep femoral artery |
| Nerve | obturator nerve |
Why does my pectineus muscle hurt?
The most common causes of injury to the pectineus muscle is from over-exertion or over-extension of stride performed by power walkers and some runners, and is often referred to as a groin strain. Localized pain in the groin area, on one side or the other, is a primary indication of injury to the pectineus.
What is the antagonist of the pectineus?
The pectineus is so closely joined with the obturator externus, its antagonist, (a lateral rotator) which also originates at the rami of pubis, inserts (although lower) onto the femur, and they are innervated by the same obturator L3 &4 nerves.
