What is the metaphysis quizlet?

What is the metaphysis quizlet?

Define “Metaphysis” The metaphysis is the wider portion of a long bone adjacent to the epiphyseal plate. It is this part of the bone that grows during childhood; as it grows, it ossifies near the diaphysis and the epiphyses.

What is the metaphysis?

The metaphysis is the region where the epiphysis joins the diaphysis; in a growing bone this corresponds to the calcified layer of the epiphyseal plate together with the interdigitating bone (see Figure 4.19). The interface between the hypertrophic and calcified layers is sometimes referred to as the tidemark.

What is the function of metaphysis?

function in bone structure This region (metaphysis) functions to transfer loads from weight-bearing joint surfaces to the diaphysis. Finally, at the end of a long bone is a region known as an epiphysis, which exhibits a cancellous internal structure and comprises the bony substructure of the joint surface.

What type of bone tissue is located in the epiphysis of long bones quizlet?

Each epiphysis consists of a thin layer of compact bone overlying spongy bone.

Is the metaphysis the growth plate?

The metaphysis is the neck portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses.

What are the zones of metaphysis?

What is metaphysis and diaphysis?

The long bone in a child is divided into four regions: the diaphysis (shaft or primary ossification centre), metaphysis (where the bone flares), physis (or growth plate) and the epiphysis (secondary ossification centre). In the adult, only the metaphysis and diaphysis are present (Figure 1).

Where is the metaphyseal?

Where is the diaphysis?

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. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate.

What is epiphysis and metaphysis?

The epiphysis (from Ancient Greek ἐπί (epí) ‘on top of’, and φύσις (phúsis) ‘growth’) is the rounded end of a long bone, at its joint with adjacent bone(s). Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate).

Is the metaphysis part of the shaft?

The metaphysis is the neck portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses….

How is metaphysis different from diaphysis?

Generally, diaphysis is attached to the epiphyses from both ends through the metaphysis. In addition, the outer layer of the diaphysis is made up of cortical bone, which is a type of dense and hard bone tissue. In contrast, the medullary cavity of the diaphysis contains yellow bone marrow.
