The acetabulum is the cup-shaped socket on the lateral aspect of the pelvis, which articulates with the head of the femur to form the hip joint.
What bone articulates with the femur?
1 – Femur and Patella: The femur is the single bone of the thigh region. It articulates superiorly with the hip bone at the hip joint, and inferiorly with the tibia at the knee joint. The patella only articulates with the distal end of the femur.
Which bone articulates with the femur quizlet?
The posterior aspect of the patella articulates with the femur. The broad superior portion of the patella is called the apex.
Does the femur articulate with the hip bone?
The femur articulates proximally with the acetabulum of the pelvis to form the hip joint, and distally with the tibia and patella to form the knee joint.What part of the femur articulates with the patella quizlet?
To what does the patellar surface of the femur articulate? The patellar surface of the femur articulates with the patella.
Which bones articulates with the humerus?
humerus, long bone of the upper limb or forelimb of land vertebrates that forms the shoulder joint above, where it articulates with a lateral depression of the shoulder blade (glenoid cavity of scapula), and the elbow joint below, where it articulates with projections of the ulna and the radius.
Where does the end of the femur with the femoral head articulate?
The femoral head of the proximal femur articulates with the acetabulum of the pelvis in which the femoral head acts at the ball and the acetabulum as the socket.
What bone articulates with the medial and lateral condyles of the femur?
The medial and lateral femoral condyles articulate with the medial and lateral condyles of the tibia to form the knee joint. The knee is comprised of three bones, the femur, patella, and tibia. As mentioned previously, the knee is the most weight-bearing joint in the human body making it highly susceptible to injury.Which part of the femur articulates with the tibia to form the knee joint?
The medial and lateral femoral condyles articulate with the tibia to form the knee joint. The femur also articulates with the patella.
What does the patella articulate with?The patella, the largest sesamoid bone in the body, articulates only with the patellar surface of the distal femur (patellar notch). The patella rides in the tendon of the quadriceps femoris—the largest muscle of the thigh and the primary extensor of the knee.
Article first time published onWhat is the end of the femur called?
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.
Where is the proximal femoral diaphysis?
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.
Which end of the femur forms part of the knee?
Two large prominences, or condyles, on either side of the lower end of the femur form the upper half of the knee joint, which is completed below by the tibia (shin) and patella (kneecap).
What bone articulates with the scapula and sternum?
The clavicle articulates at one end with the sternum (chest bone) and with the acromion of the scapula at the other. This articulation between the acromial end of the clavicle and the acromion of the scapula forms the roof of the shoulder.
Which bone articulates with the ulna?
The ulna articulates with the humerus at its most proximal point forming the elbow in a hinge joint. It is the trochlea of the humerus which sits in the semi-lunar notch of the ulna to form this joint.
What is the name of the bone that articulates with the tibia to form the ankle joint?
Now let’s look at the bone that articulates with the tibia and fibula to form the ankle joint – the talus. This is the talus. The bone below and behind it is the calcaneus, or heel bone. The bone in front of the talus is the navicular bone.
Do both the tibia and fibula articulate with the femur?
The fibula does not reach the femur but articulates with the tibia at both its proximal and distal ends. Movement between these bones is limited. … Its lower end is the distal malleolus that forms the big lateral ankle bulge.
Which bone articulates with the ulna quizlet?
-The ulna and radius articulate with the humerus at the elbow joint. The articulation occurs in two places: where the head of the radius articulates with the capitulum of the humerus, and where the trochlear notch of the ulna articulates with the trochlea of the humerus.
What articulates with the lateral condyle of the femur?
Similarly, the smooth region of the distal and posterior medial femur is the medial condyle of the femur, and the irregular outer, medial side of this is the medial epicondyle of the femur. The lateral and medial condyles articulate with the tibia to form the knee joint.
What bone articulates with the first metatarsal?
On the lateral part of the plantar surface there is a rough oval prominence, or tuberosity, for the insertion of the tendon of the fibularis longus. The first metatarsal articulates (forms joints) with the medial cuneiform and to a small extent with the intermediate cuneiform bone.
What bone marking of the femur articulates with the pelvic girdle?
You “sit on the ischium” portion of the coxal bone. It is thicker and stronger than the pubis, allowing it to support your weight. The large socket of the coxal bone is called the acetabulum (“ah-set-TAB-you-lum”). It faces laterally and is where the ball-like head of the femur bone articulates with the pelvis.
What kind of bone is the patella and what bone does it articulate with?
PatellaPronunciation/pəˈtɛlə/Originspresent at the joint of femur and tibia fibulaIdentifiersLatinpatella
What does the patella articulate with in flexion?
The superior two thirds of the posterior articular surface of patella articulates with the anterior surface of the femoral condyles. … However the medial femoral condyle is larger and projects further anteriorly than the lateral femoral condyle.
Is patella tendon anterior or posterior?
The patella is the largest sesamoid bone in the human body and is located anterior to knee joint within the tendon of the quadriceps femoris muscle, providing an attachment point for both the quadriceps tendon and the patellar ligament.
Where is shaft of femur?
The long, straight part of the femur is called the femoral shaft. When there is a break anywhere along this length of bone, it is called a femoral shaft fracture. This type of broken leg almost always requires surgery to heal. The femoral shaft runs from below the hip to where the bone begins to widen at the knee.
Where does the femur start and end?
The femur is located, as the common term for it suggests, in the thigh or upper portion of the leg and it runs from the hip to the knee. The proximal end of the bone, the part that is located closest to the hip, has the femoral head that helps to create the joint within the hip.
What does the distal femur articulate with?
The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint.
What is spiral line of femur?
a curved line with its superior end adjacent to the lesser trochanter, nearly continuous with the intertrochanteric line, and converging inferiorly with the pectineal line to form the medial lip of the linea aspera; forms the medial boundary of the distal attachment of the iliacus muscle.
Where is the intercondylar notch?
The intercondylar notch, or intercondylar fossa, is the area of the posteroinferior aspect of the distal femur between its condyles.
What ligaments and tendons are attached to the femur?
Collateral ligaments: The two collateral ligaments are like straps on each side of your knee. 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.
What are the parts of the femur?
- Head of femur. Caput femoris. The femoral neck is about 5 cm long and can be subdivided into three regions. …
- Neck of femur. Collum femoris. …
- Greater trochanter of femur. Trochanter major femoris.
