Which muscle attaches most proximal on the femur?
pectineus muscle
On the medial, proximal, posterior part of the femur is another (smaller ridge) known as the pectineal line. It acts as the point of attachment for the pectineus muscle.
Where do muscles attach on the femur?
In primitive tetrapods, the main points of muscle attachment along the femur are the internal trochanter and third trochanter, and a ridge along the ventral surface of the femoral shaft referred to as the adductor crest.
What muscles attach to the femur bone?
The quadriceps include four large muscles, rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The quadriceps femoris is one of the strongest muscle groups in the body that covers the anterior aspect of the femur. This group of muscles has a common function. They extend the leg at the knee joint.
What is the proximal portion of the femur?
Proximal femur includes the femoral head, neck and the region 5-cm distal to the lesser trochanter. There is a 125°–130° inclination angle between the head and neck and the femoral body. Further, there is a 15° anteversion angle between the plane passing through the condyles of the femoral head and the femur neck.
What muscles attach to the linea aspera?
Attachments
- pectineus.
- adductor minimus.
- adductor brevis.
- adductor longus.
- adductor magnus (hamstrings part)
What attaches to linea aspera?
The adductor part attaches distally to the linea aspera, the gluteal tuberosity on the femur and the medial supracondylar line on the distal femur. The hamstring portion attaches onto the femur at the adductor tubercle on the inferomedial portion of the bone.
What muscle connects thigh to hip?
The gluteal muscles can be divided into two main groups: Large and superficial muscles which mainly abduct and extend the thigh at the hip joint. These are the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.
What tendons are attached to the femur?
A long tendon called the iliotibial band runs along the femur from the hip to the knee and serves as an attachment site for several hip muscles including the following: Gluteal: These are the muscles that form the buttocks.
What ligaments are attached to the femur?
The medial collateral ligament (MCL) is on the inner side of your knee. It attaches the thigh bone (femur) to the shin bone (tibia). The lateral collateral ligament (LCL) is on the outer side of your knee. It connects your femur to your calf bone (fibula).
What is proximal femoral nailing?
The proximal femoral nail (PFN) is an osteosynthetic implant designed to treat proximal femoral fractures in the trochanter area with a closed intramedullary fixation method.
Which muscles originate from linea aspera of the femur?
rectus femoris muscle.
What muscles attach to the adductor tubercle?
The adductor tubercle is the point of insertion for the adductor minimus and the hamstrings part of the adductor magnus.
What is the proximal attachment of gracilis?
Gracilis muscle
| Origin | Anterior body of pubis, inferior pubic ramus, ischial ramus |
|---|---|
| Insertion | Medial surface of proximal tibia (via pes anserinus) |
| Actions | Hip joint: Thigh flexion, thigh adduction; Knee joint: leg flexion, leg internal rotation |
| Innervation | Obturator nerve (L2-L3) |
What are the attachments of the gracilis?
The gracilis muscle arises from the pubic bone and descends along the medial thigh. This medial compartment muscle travels distally and, as mentioned above, unites with the semitendinosus and sartorius to form the pes anserinus, which attaches to the medial tibia.
What muscles attach to the linea aspera of femur?
What tendons are attached to femur?

|---|---|
| Which of the following muscles attach to the hip bones? | rectus abdominis, rectus femoris |
How many ligaments are attached to the femur?
In the hip, the joint capsule is formed by a group of three strong ligaments that connect the femoral head to the acetabulum. These ligaments are the main source of stability for the hip.
