femur, also called thighbone, upper bone of the leg or hind leg. The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament (ligamentum teres femoris) within the socket and by strong surrounding ligaments.
Is a femur bone? The femur (thigh bone) is the largest bone in your body. The femur is the only bone in the upper portion of your leg, and it is completely covered by your thigh muscles.
Similarly, What is the femur bone connected to? The femur or thigh bone is one of the longest bones in the human body. The upper part of the thigh bone consists of the femoral head, femoral neck, and greater and lesser trochanters. The head of the femur joins the pelvis (acetabulum) to form the hip joint.
What type of bone is the femur?
Structurally, the femur is a long bone, meaning its length is greater than its width, while the patella, a sesamoid bone, is small and round.
What holds the femur in place?
The femur has a ball-shaped head on its end that fits into a socket formed in the pelvis, called the acetabulum. Large ligaments, tendons, and muscles around the hip joint hold the bones (ball and socket) in place and keep it from dislocating.
Which type of bones forms the arms and legs?
Long bone – has a long, thin shape. Examples include the bones of the arms and legs (excluding the wrists, ankles and kneecaps). With the help of muscles, long bones work as levers to permit movement.
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).
How is the femur attached to the hip? The socket area (acetabulum) is inside the pelvis. The ball part of this joint is the top of the thighbone (femur). It joins with the acetabulum to form the hip joint. The hip is one of the most stable joints in the body.
What bones are in your leg?
The bones of the human leg, like those of other mammals, consist of a basal segment, the femur (thighbone); an intermediate segment, the tibia (shinbone) and the smaller fibula; and a distal segment, the pes (foot), consisting of tarsals, metatarsals, and phalanges (toes).
What are your leg bones called? Four bones make up the leg: Femur. Tibia. Fibula.
What tendons attach 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 quizlet? or fibular collateral ligament. This round, cord-like ligament attaches to the lateral condyle of the femur and runs down to the head of the fibula, independent of any attachment to the lateral meniscus. It protects the joint from stresses to the medial side of the knee. it is quite strong and not commonly injured.
How do you identify the femur bone?
Because humans walk upright, the thigh bone, otherwise known as the femur, is the longest, strongest bone in the body. On the other hand, the femur will be the same length as other bones in animals. Look for the long bone starting just above the knee and extending up towards the pelvis.
How are bones in the arms and legs similar?
The arms and legs have similar design. There are long upper bones. In the arm it is the humerus and in the leg it is the femur. Also, there are two long bones in the medial region: The ulna and radius in the arm and the tibia and fibula in the leg.
What are the parts of the femur bone? The femur acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. Proximal Femur consists of: femoral head – pointed in a medial, superior, and slightly anterior direction.
How do you find the femur bone?
What muscles are attached to the femur?
Femoral muscles, Gluteus medius, Gluteus minimus, Piriformis, Superior gemellus, Tensor fasciae latae, Obturator internus, Inferior gemellus, Quadratus femoris, Semitendinosus, Semimembranosus, Biceps femoris, Illiacus, Psoas major, Psoas minor, Iliopsoas, (more…)
What muscle attaches to the hip bone? Musculature
| Muscle | Action | Nerve |
|---|---|---|
| Pectineus | Hip flexion | Femoral nerve |
| Rectus femoris | Hip flexion, leg extension | Femoral nerve |
| Adductor magnus (anterior part) | Hip flexion, adduction | Obturator |
| Adductor magnus (posterior part) | Thigh extension | Tibial |

What joint connects the femur and tibia?
The knee is the large lower extremity joint connecting the femur and the tibia. The knee supports nearly the entire weight of the body, and is vulnerable to both acute injury and the development of osteoarthritis.
Where is the femur and tibia located? The femur or thighbone is the bone connecting the hip to the knee. The tibia or shinbone connects the knee to the ankle. The patella (kneecap) is the small bone in front of the knee and rides on the knee joint as the knee bends. The fibula is a shorter and thinner bone running parallel to the tibia on its outside.
Is the thigh part of the leg?
Upper leg anatomy and function. The upper leg is often called the thigh. It’s the area that runs from the hip to the knee in each leg.
What part of the femur articulates with the patella quizlet? The patellar surface of the femur articulates with the patella.
