What muscles attach to the femur?

What muscles attach to the femur?

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.

What are four proximal landmarks on the femur?

The proximal end of the femur includes the:

• femoral head.
• neck.
• trochanters.
• intertrochanteric crest.
• intertrochanteric line.

Which proximal features of the femur serve as points of attachment for muscles of the leg?

Below the greater trochanter is the lesser trochanter, situated at the base of the neck of the femur. The lesser trochanter is the part of the femur attached to a pair of muscles that help flex the thigh (lift the leg forward).

What is the proximal part 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.

Where is the proximal end of the femur?

The rounded, proximal end is the head of the femur, which articulates with the acetabulum of the hip bone to form the hip joint. The fovea capitis is a minor indentation on the medial side of the femoral head that serves as the site of attachment for the ligament of the head of the femur.

What is the proximal end of the femur called?

femoral head
The femur is the bone of the upper leg. The proximal end of the femur connects to the hip joint. It is marked by a spherical ball, called the femoral head, that fits into the socket of the hip joint, the acetabulum.

What landmark is found on the anterior surface of the femur?

The lesser trochanter is a small, bony prominence that lies on the medial aspect of the femur, just below the neck. A single, powerful muscle attaches to the lesser trochanter. Running between the greater and lesser trochanters on the anterior side of the femur is the roughened intertrochanteric line.

Which of the following landmarks is found on the proximal end of the humerus?

Which of the following landmarks found on the proximal end of the humerus? The greater tubercle is adjacent to the head of the humerus. It is the insertion site for some of the rotator cuff muscles.

Where does the anterior cruciate ligament attach to the femur?

Facet for attachment of anterior cruciate ligament – Found on the lateral wall of the intercondylar fossa, it is smaller than the facet on the medial wall and is where the anterior cruciate ligament of the knee attaches. Iliacus muscle Insert into the lesser trochanter of the femur. Psoas major muscle Insert into the lesser trochanter.

Where does the femur head articulate with the pelvis?

The proximal femoral head articulates with the acetabulum of the pelvis, forming a “ball-and-socket” joint. This formation allows for three planes movement at the hip joint: abduction and adduction in the frontal plane, flexion, and extension in the sagittal plane and internal and external rotation in the horizontal plane.

Where does the gluteus maximus attach to the femur?

The lateral border becomes the gluteal tuberosity, where the gluteus maximus attaches. Distally, the linea aspera widens and forms the floor of the popliteal fossa, the medial and lateral borders form the medial and lateral supracondylar lines. The medial supracondylar line ends at the adductor tubercle, where the adductor magnus attaches.

What do you mean by proximal and distal attachments?

Proximal and Distal Attachments In most cases this text uses the terms proximal attachment and distal attachment to refer to the specific sites of these connective tissue attachments of muscles onto bone (s) in order to reflect the concept that when a muscle contracts, either end can move, depending on the goal and conditions of the movement.
