What is epiphysis and diaphysis?

The main difference between epiphysis and diaphysis is that epiphysis is the rounded end of a long bone, at its joint with adjacent bone(s), whereas diaphysis is the main or midsection (shaft) of a long bone. Furthermore, epiphysis is made up of spongy bone while diaphysis is made up of cortical bone.

What do you mean by Epiphyses?

Definition of epiphysis 1 : a part or process of a bone that ossifies separately and later becomes ankylosed to the main part of the bone especially : an end of a long bone. 2 : pineal gland.

What does diaphyseal mean?

the shaft of a long bone
the shaft of a long bone.

What is the common term for epiphysis?

epiphysis. / (ɪˈpɪfɪsɪs) / noun plural -ses (-ˌsiːz) the end of a long bone, initially separated from the shaft (diaphysis) by a section of cartilage that eventually ossifies so that the two portions fuse together. Also called: epiphysis cerebri (ˈsɛrɪˌbraɪ) the technical name for pineal gland.

What is epiphysis and metaphysis?

The epiphysis 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).

What is proximal epiphysis?

The proximal epiphysis is the end of the long bone closest to the center of the body. The distal epiphysis is located at the end of the long bone that is farther away from the center of the body.

What is atavistic epiphysis?

Atavistic epiphysis: A bone that is independent phylogenetically but is now fused with another bone. These types of fused bones are called atavistic, e.g., the coracoid process of the scapula, which has been fused in humans, but is separate in four-legged animals.

What is distal epiphysis?

The distal epiphysis is the rounded part of the bone found at the end of the diaphysis that is pointing away from the center of the body. The distal epiphysis is also is covered in articular cartilage, enabling bones to move at the joints without grinding on each other.

What is an example of an epiphysis?

Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. the head of the femur, part of the hip joint complex). Examples of traction epiphyses are tubercles of the humerus (greater tubercle and lesser tubercle), and trochanters of the femur (greater and lesser).

What are the four types of epiphysis?

Why is the epiphysis important?

The epiphysis is a common site of injury in the growing skeleton. Because the epiphysis is responsible for longitudinal bone growth, injury disrupting vascular supply to the epiphysis or metaphysis affects bone growth. The distal tibia, fibula, ulna, and radius are the most common sites affected.

What color is the epiphysis?

EPIPHYSIS (end) (a), EPIPHYSIAL LINE (a) – purple The epiphysis is the end of a long bone. Externally it has a thin layer of compact bone, while internally the bone is cancellous.

What is meant by epiphysis?

Epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.

What does epiphysis mean in anatomy?

n, pl -ses (-ˌsiːz) 1. (Anatomy) the end of a long bone, initially separated from the shaft (diaphysis) by a section of cartilage that eventually ossifies so that the two portions fuse together. 2. (Anatomy) Also called: epiphysis cerebri the technical name for pineal gland.

Is epiphysis singular or plural?

The plural form of epiphysis is epiphyses . Find more words! The use of androgens by adolescents who have not completed their full growth will eliminate further growth by closing the bone epiphyses. This growth occurs at the epiphyses, where the main shaft of a bone joins the parts which are shaped to fit a joint at each end.

What does epiphysis cerebri mean?

The pineal gland, conarium, or epiphysis cerebri, is a small endocrine gland in the brain of most vertebrates. The pineal gland produces melatonin, a serotonin -derived hormone which modulates sleep patterns in both circadian and seasonal cycles. The shape of the gland resembles a pine cone, and gives it its name.
