What is the structure of the long bone quizlet?

Shaft of long bone – compact bone with a hollow center – provides strength as muscles move the bone and the person. Lines medullary cavity, provides osteoblasts for repair and remodeling. Growth plate, forms joint with another’s epiphysis. Encloses yellow bone marrow.

What is the function of long bones in the body?

Long Bones Support Weight and Facilitate Movement 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.

What is the structure of the long bone?

A long bone is a bone that has a shaft and 2 ends and is longer than it is wide. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.

What are the 3 structures of long bones?

Long bones are longer than they are wide. They can be divided into three regions – epiphysis, metaphysis and the diaphysis.

What is the difference between long bone and short bone?

Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.

What covers the end of a long bone?

hyaline cartilage
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.

Where do long bones grow in length?

The epiphyseal plate
The epiphyseal plate is the area of growth in a long bone. It is a layer of hyaline cartilage where ossification occurs in immature bones. On the epiphyseal side of the epiphyseal plate, cartilage is formed. On the diaphyseal side, cartilage is ossified, and the diaphysis grows in length.

What are long bones called?

The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones.

What are the 5 major parts of a long bone?

List five major parts of a long bone. The major parts of a long bone include epiphysis, articular cartilage, diaphysis, periosteum, medullary cavity, endosteum, and marrow. How do compact and spongy bone differ in structure? The wall of the diaphysis is mainly composed of tightly packed tissue called compact bone.

What is unique about long bones?

What is the function of a short bone?

Short bones have very equal proportions and are roughly shaped like a cube. Examples can be found in the bones of your wrists and ankles. Short bones provide stability to the wrist and ankle joints and also help facilitate some movements.

What are the 3 main parts of a long bone?

Long bones are longer than they are wide. They can be divided into three regions – epiphysis, metaphysis and the diaphysis. The epiphysis contains the spongy bone (also called cancellous), which in turn contains the red bone marrow that is responsible for synthesizing blood cells.

What is the end of a long bone called?

epiphysis
The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.

Where are the long bones?

All of the bones in the arms and legs, except the patella, and bones of the wrist, and ankle, are long bones.

What’s a long bone?

Overview. A long bone is a bone that has a shaft and 2 ends and is longer than it is wide. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.

What makes a long bone a long bone?

What bones are long bones?

The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones. The long bones of the human leg comprise nearly half of adult height.

What type of tissue is found in bones?

are organs composed of a complex arrangement of several tissues. compact and spongy osseous tissues, connective tissues, cartilage, and adipose tissue. In addition, bones contain blood vessels and nerves.

What are the characteristics of a bone?

In addition, bones contain blood vessels and nerves. long, short, flat, irregular, and sesamoid. are longer than they are wide, with a thick compact bone exterior. An example is the femur and humerus. are almost equal in length and width and contain a thick interior of spongy bone covered by a thin veneer of compact bone.

Which type of bone tissue degenerates first in osteoporosis?

Which type of bone tissue, compact bone or spongy bone, significantly degenerates first in osteoporosis? Compact bone. The osseous tissue cells that secrete collagen.

What is the function of the central canal in bone?

The central canal contains blood vessels, lymphatic vessels, and nerves that serve compact bone tissue. The blood vessels, lymphatic vessels, and nerves travel from the periosteum, dense regular connective tissue covering the bone surface, to the central canal through these canals.
