What is the head of a long bone called?
epiphysis
The proximal (closer to the body) epiphysis of the humerus and the proximal epiphysis of the femur are shaped in a rounded manner, called the head, and look a bit like half of a ball. This shape allows those two long bones to rotate in multiple directions.
What term refers to the end of a long bone?
The end of the long bone is the epiphysis and the shaft is the diaphysis.
What is the end of a long bone called quizlet?
the enlarged ends of the long bone are the epiphysis. The epiphyses of a bone articulates, or meets, with a second bone at a joint. Each epiphyses consists of a thin layer of compact bone overlying spongy bone.
What is another name for the shaft longest part of a long bone?
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
What are the parts of a long bone?
A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.
Why is the end of a long bone called epiphysis?
The epiphysis is the rounded end of a long bone. Epiphyses are rounded because long bones form joints with other bones; the rounded shape lets them move more smoothly in the joint, giving you more motion.
What are the two flared ends of the long bone called?
The articular cartilage is itself not innervated. The ends of long bones that articulate with each other are often flared to form bulbous projections called condyles. These are lined by articular or hyaline cartilage.
Is the flared end of a long bone?
Internal structure of a human long bone, with a magnified cross section of the interior. The central tubular region of the bone, called the diaphysis, flares outward near the end to form the metaphysis, which contains a largely cancellous, or spongy, interior.
What are the 5 major parts of a long bone?
List five major parts of a long bone. Epiphysis, diaphysis, periosteum, yellow marrow, medullary cavity, compact bone, spongy bone, articular cartilage.
What are the 7 parts of a long bone?
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 type of bone lines the shaft of long bones?
A hollow medullary cavity filled with yellow marrow runs the length of the diaphysis of a long bone. The walls of the diaphysis are compact bone. The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow.
What are the 3 parts of long bone?
Long bones are longer than they are wide. They can be divided into three regions – epiphysis, metaphysis and the diaphysis.
