What type of bone is the femur bone?
The long bones, longer than they are wide, include the femur (the longest bone in the body) as well as relatively small bones in the fingers. Long bones function to support the weight of the body and facilitate movement.
Is the femur a flat bone?
Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Flat bones are thin, but are often curved, such as the ribs. Irregular bones such as those of the face have no characteristic shape.
What is a femur best classified as?
The femur is classified structurally as a long bone and is a major component of the appendicular skeleton.
Is the femur an example of a long bone?
Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.
What are the 4 main types of bones?
There are four different types of bone in the human body:
- Long bone – has a long, thin shape.
- Short bone – has a squat, cubed shape.
- Flat bone – has a flattened, broad surface.
- Irregular bone – has a shape that does not conform to the above three types.
What are the 3 types of skeleton?
A skeleton is a structural frame that supports an animal body. There are several different skeletal types: the exoskeleton, which is the stable outer shell of an organism, the endoskeleton, which forms the support structure inside the body, and the hydroskeleton, a flexible skeleton supported by fluid pressure.
What are the 9 types of bones?
The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1).
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.
What are the 3 major leg bones?
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).
Is a femur a bone?
Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Motor vehicle collisions, for example, are the number one cause of femur fractures. The long, straight part of the femur is called the femoral shaft.
What are the 4 types of skeletons?
Types of skeletons
- Pliant skeletons.
- Rigid skeletons.
- Fluid skeletons.
What is endoskeleton and exoskeleton?
An exoskeleton is a hard external skeleton that protects the outer surface of an organism and enables movement through muscles attached on the inside. An endoskeleton is an internal skeleton composed of hard, mineralized tissue that also enables movement by attachment to muscles.
What is the femur bone in your body called?
The thigh bone, which is also called the femur, is the bone inside the human body located between the hip and the knee of each leg. The top of the thigh bone is connected to the hip, forming the hip joint, and the bottom of the bone is connected to the knee, forming the knee joint.
What are other names for the femur bone?
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.
What bone is above the femur?
Femur is the bone of leg that articulates above with the hip bone to form hip joint and below with the tibia and patella to form the knee joint.
What does the femur bone look like?
The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur is connected to the shaft through the neck or collum.
