Anatomy Of A Femur Bone

Coated meniscus tissue layers on top of the bone and provides synovial fluid for frictionless movement within the knee. The axis of the head and neck angles anteriorly while the transverse axis of the femoral condyles remains flat in the coronal plane Pectineal line of femur Line inferior from the lesser trochanter on the posterior surface of femur Converges with spiral line to form the medial lip of linea aspira.

Pin On Weapon And War Anatomy

Like the humerus it has a proximal spherical head for the omniaxial rotation in the hip joint and a more complex-shaped distal articular surface for the articulation in the most complex joint in the human body the knee joint.

Anatomy of a femur bone. Blood flow in the femur is hard to measure. The medullary cavity contains red bone marrow which is involved in the production of red blood cells. The femur is part of the appendicular skeleton and this bone is classified as a long bone which makes sense considering the femur just so happens to be the longest biggest and strongest bone in the human skeleton.

The Lower portion of the femur bone consists of two condyle from the Greek word for knuckle lateral and medial that create the surface for the upper tibia bone and the knee-joint. A proximal extremity a shaft in the middle of the bone and a distal extremity. It has three parts.

More deep in horse. It is composed of an upper end a lower end and a shaft. The anatomy and functional Axes of the Femur.

We will consider the following important osteological features to compare femur bone. J Bone Joint Surg 69-A873-880. Os femoris is the only bone in the thigh and it articulates at the hip and knee joints.

Proximal shaft and distal. It acts as the site of origin and attachment of many muscles and ligaments and can be divided into three parts. The rounded shape of the head allows the femur to move in almost any direction at the hip including circumduction as well as rotation around its axis.

So lets review the anatomy of the femur bone. It is both the longest and the strongest bone in the human body extending from the hip to the knee. A femur or thigh bone is the longest bone in the human body.

Shallow on ox sheep and goat. Present only in horse not present in ox sheep goat and dog. In the erect posture it is not vertical being separated above from its fellow by a considerable interval which corresponds to the breadth of the pelvis but inclining gradually downward and medialward so as to approach its fellow toward its lower.

It is the longest bone in the human body. 244 245 the longest and strongest bone in the skeleton is almost perfectly cylindrical in the greater part of its extent. The femur bone is the strongest and longest bone in the body occupying the space of the lower limb between the hip and knee joints.

244 245 the longest and strongest bone in the skeleton is almost perfectly cylindrical in the greater part of its extent. Femur upper bone of the leg or hind leg. Anatomy of Femur Bone.

In the erect posture it is not vertical being separated above from its fellow by a considerable interval which corresponds to the breadth of the pelvis but inclining gradually downward and medialward so as to approach its fellow toward its lower part for the purpose of bringing the knee-joint near the line of gravity of the body. Over time red bone marrow is replaced by yellow bone marrow which helps to store fat. The femur also thigh bone Latin.

The femur ˈ f iː m ər pl. The femur is the primary bone of the leg and all other leg bones are attached to the distal portion of the femur. The femur is the only bone located within the human thigh.

The femur is the only bone in the thigh and the longest bone in the body. The head forms a ball-and-socket joint with the hip at the acetabulum being held in place by a ligament within the socket and by strong surrounding ligaments. In this article we shall look at the anatomy of the femur its attachments bony landmarks and clinical correlations.

Comparative anatomy of femur bones of different animal. The upper and bears a rounded head whereas the lower end is widely expanded to from two large condyles. Femurs or femora ˈ f ɛ m ər ə or thigh bone is the proximal bone of the hindlimb in tetrapod vertebratesThe 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 jointBy most measures the two left.

Important features of this bone. In humans the neck of the femur connects the shaft and head at a 125 degree angle which is efficient for walking. The head is directed medially.

Femur anatomy is so unique that it makes the bone suitable for supporting the numerous muscular and ligamentous attachments within this region in addition to maximally extending the limb during ambulation. The femur is also called the thigh bone and is the longest and strongest bone of the body. The head of the femur forms the ball-and-socket hip joint with the cup-shaped acetabulum of the coxal hip bone.
