Likewise, what is the main bone in your leg?

Femur – the bone in the thigh. Patella – the knee cap. Tibia – the shin bone, the larger of the two leg bones located below the knee cap. Fibula – the smaller of the two leg bones located below the knee cap.

Likewise, what is the weakest bone in your leg? This long bone connects with the knee at one end and the ankle at the other. Next to the tibia is the fibula, the thinner, weaker bone of the lower leg. It is also known as the calf bone, as it sits slightly behind the tibia on the outside of the leg.

In this regard, what are considered long bones?

Long Bones Support Weight and Facilitate Movement Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).

What is the function of the long bone?

Our long bones are hard, dense bones that provide strength, structure, and mobility, typically found in the upper and lower extremities (arms and legs). The femur (thigh bone) is a good example of a long bone as it allows us to walk and supports our skeleton.

What are the two lower leg bones called?

The lower leg is comprised of two bones, the tibia and the smaller fibula. The thigh bone, or femur, is the large upper leg bone that connects the lower leg bones (knee joint) to the pelvic bone (hip joint).

What's the weakest bone in the body?

The lacrimal bone is perhaps the most fragile bone of the face and one of the smallest bones in the body. Spanning between the middle of each eye socket, each lacrimal is thin and scalelike and serves as support for the eye.

Which lower leg bone is closest to the midline of the body?

The lower leg contains two major long bones, the tibia and the fibula, which are both very strong skeletal structures. The tibia (also called the shinbone) is located near the midline of the leg and is the thicker and stronger of the two bones.

How many bones are in your hand and leg?

Appendicular bones: The 126 appendicular bones are made up of 64 bones in the upper extremities (the arms, wrists, and hands) and 62 bones in the lower extremities (the legs, ankles, and feet).

What do shin bones look like?

The tibia and fibula are the two long bones in the lower leg. They are closely linked at the knee and ankle, but they are two separate bones. The tibia is the bone that forms the shin and is the larger of the two lower-leg bones.

What does a human leg bone look like?

The forearm and the lower leg have two long bones each. In the forearm are the radius—on the thumb side of the forearm—and the ulna; in the lower leg are the tibia (the shinbone) and the fibula. The radius corresponds to the tibia and the ulna to the fibula.

What are the 4 types of bone?

Long Bones

The bones of the body come in a variety of sizes and shapes. The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones.

What are the two major types of bones?

Shown are different types of bones: flat, irregular, long, short, and sesamoid. Figure 2. The long bone is covered by articular cartilage at either end and contains bone marrow (shown in yellow in this illustration) in the marrow cavity. Long bones are longer than they are wide and have a shaft and two ends.

Are bones stronger than steel?

The human body can take a remarkable amount of punishment, given bones made of one of the strongest materials found in nature. Bone is extraordinarily strong — ounce for ounce, bone is stronger than steel, since a bar of steel of comparable size would weigh four or five times as much.

How does long bone grow?

Long bone. They grow primarily by elongation of the diaphysis, with an epiphysis at each end of the growing bone. The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate.

What is the basic unit of bone?

The microscopic structural unit of compact bone is called an osteon, or Haversian system. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella).

What is the site of spongy bone in adults?

The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled internally with spongy bone, another type of osseous tissue. Red bone marrow fills the spaces between the spongy bone in some long bones. Each epiphysis meets the diaphysis at the metaphysis.

What type of bone is a phalanx?

The phalanges /f?ˈlænd?iːz/ (singular: phalanx /ˈfælæŋks/) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones.

What is spongy bone also called?

Cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.

How painful is it to break a bone?
