Metaphysis

Metaphysis is an important part of the tubular bones, which plays a key role in the growth and development of the body. The metaphysis is located between the epiphysis (top of the bone) and the diaphysis (middle part of the bone) and is a narrow transition zone between them.

In childhood and adolescence, the metaphysis is the site of active growth of bone in length. There is a special layer of cartilage called the epiphyseal plate, which constantly divides and gives rise to new cells, which then turn into bone tissue. The growth process occurs due to the constant division of cartilage cells and their subsequent mineralization, which leads to an increase in bone length.

When the bone reaches its maximum length, metaphyseal growth slows and cartilage cells stop dividing. At this point, the metaphysis turns into the epiphysis and ceases to participate in bone growth.

The metaphysis also plays a role in maintaining the bone structure and ensuring its strength. It contains bone marrow, which produces blood-forming cells and provides the body's immune defense.

Although the metaphysis is an important part of the bone structure, it can also be susceptible to various diseases. For example, osteomyelitis (inflammation of the bone) can damage the metaphysis and impair its growth. The metaphysis can also be affected by diseases such as dystrophy, dysplasia and bone cancer.

Overall, the metaphysis plays an important role in the growth and development of the body, as well as in maintaining its structure and strength. Therefore, if you experience any problems with the skeletal system, including the metaphysis, it is important to consult a doctor for diagnosis and treatment.



The metaphysis is an expanded area of ​​bone with spongy tissue and is located between the diaphysis in babies with an epiphesal appearance. The pituitary gland is located in the pineal gland. The main structures of the diaphysis are connected to each other by metaphyses through synarthrosis (types of joints). There are no tissues in the metaphyseal area, hence the extensibility of the metaphysis is especially pronounced (movement with increased dissipation of elastic stresses due to the absence of elastic bonds at the location). The epiphysis predominates in the arms, legs, and fibula. Accordingly, the legs of the pituitary gland are located further, and the pituitary gland in the radial girdle corresponds to the upper limb.
