What is the epiphysis region?
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 the epiphysis contain?
The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow. The epiphyseal plate, a layer of hyaline cartilage, is replaced by osseous tissue as the organ grows in length.
What type of cartilage is the epiphysis?
hyaline cartilage tissue
Epiphyseal cartilage is hyaline cartilage tissue with a gelatinous texture, and it is responsible for the longitudinal growth of the long bones in birds and mammals. It is located between the epiphysis and the diaphysis. Epiphyseal cartilage also is called a growth plate or physis.
Which of the following regions of the epiphyseal plate is nearest the epiphysis?
The reserve zone, the region closest to the epiphyseal end of the plate, contains small chondrocytes within the matrix.
In what region of the epiphyseal plate does growth occur?
It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length)….

What is epiphysis function?
Epiphysis Definition – Epiphysis is the rounded end of a long bone, its primary function is to connect adjacent bones to form joints.
What type of tissue covers the epiphysis of bones?
One type of connective tissue called articular cartilage (hyaline cartilage), covers the end of each bone epiphysis and acts as storage for fat, protection from disease, and support for the repair of tissue damage.
Which region of a growing bone contains the epiphyseal plate?
epiphysis
Each epiphysis meets the diaphysis at the metaphysis, the narrow area that contains the epiphyseal plate (growth plate), a layer of hyaline (transparent) cartilage in a growing bone.
Which zone of the epiphyseal plate is found at the diaphysis epiphysis Junction?
The EPIPHYSEAL LINE is located at the junction of the epiphysis and diaphysis (a region called the “metaphysis”) in adult bone. The epiphyseal line is a remnant of the EPIPHYSEAL PLATE, which is a cartilage plate that serves as a growth area for long bone lengthening.
In which zone of the epiphyseal plate are Trabeculae formed?
zone of ossification
After the zone of calcified matrix, there is the zone of ossification, which is actually part of the metaphysis. Arteries from the metaphysis branch through the newly-formed trabeculae in this zone. The newly-deposited bone tissue at the top of the zone of ossification is called the primary spongiosa.
In which region of a long bone such as the humerus would you find the epiphyseal plate?
The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone.
What is the function of epiphysis?
The epiphysis is the rounded end in the long bone, and its primary function is to form joints with adjacent bones.
What is the difference between epiphysis and subchondral bone?
At the joint, the epiphysis is also covered by articular cartilage. The subchondral bone, on the other hand, is the bone under the articular cartilage and its growth plate. Epiphysis Meaning – It is a part of the bone that ossifies separately and later becomes ankylosed to the main part of the bone especially at the end of the long bone.
What type of bone has epiphysis at both ends?
In mice and humans, most tubular bones develop an epiphysis at both ends. Some bones, such as the phalanges and the metacarpal and metatarsal bones, ordinarily form this structure at one end only. The knee joint and other diarthrodial synovial joints are lined by articular cartilage, under which is a layer of bone called the subchondral plate.
What is the structure of the epiphysis?
Structure. 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). Pressure epiphyses assist in transmitting the weight of the human body and are the regions of the bone that are under pressure during movement or locomotion.
What is a subchondral bone cyst?
What are subchondral bone cysts? Subchondral bone cysts (SBCs) are sacs filled with fluid that form inside of joints such as knees, hips, and shoulders. The sac is usually primarily filled with hyaluronic acid.
