What type of joint is found in the epiphyseal plate?
cartilaginous joint
Synchondrosis. A synchondrosis (“joined by cartilage”) is a cartilaginous joint where bones are joined together by hyaline cartilage, or where bone is united to hyaline cartilage. A synchondrosis may be temporary or permanent. A temporary synchondrosis is the epiphyseal plate (growth plate) of a growing long bone.
What is an epiphyseal joint?
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).
What is epiphyseal plate disk?
Growth plates, also called physes or epiphyseal plates, are discs of cartilage present in growing children. They are located between the middle and the end of the long bones, such as the bones of the arms and legs. Most long bones have one growth plate at each end.
What are the 5 zones of the epiphyseal plate?
Study each of the five zones of the epiphyseal plate:
- Zone of Reserve Cartilage (RC).
- Zone of Proliferating Cartilage (PC).
- Zone of Hypertrophic Cartilage (HC).
- Zone of Calcified Cartilage (CC).
- Zone of Ossification (Resorption)(OSS).
Is the epiphyseal plate a syndesmosis joint?
A temporary synchondrosis is the epiphyseal plate (growth plate) of a growing long bone. The epiphyseal plate is the region of growing hyaline cartilage that unites the diaphysis (shaft) of a long bone to the epiphysis (end of the bone).
What is the joint between the diaphysis and epiphysis?
Cartilaginous Joint These joints may be slightly mobile (amphiarthroses) or immobile (synarthroses). The joint between the epiphysis and diaphysis of growing long bones is an example. The secondary cartilaginous joint, also known as symphysis, may involve either hyaline or fibrocartilage.
What is the function of epiphyseal?
The epiphysis is the area of the long bone where bone growth takes place. Long bones actually grow from the inside out. When the bones need to grow, they grow from the epiphyseal plate and push new bone outward. When the bone is done growing, the epiphyseal plate stops creating cells.
Why are epiphyseal plates classified as joints?
The epiphyseal growth plate is a temporary cartilaginous joint formed as the cartilage is converted to bone during growth and development. Cartilaginous joints are connected entirely by cartilage and allow more movement between bones than a fibrous joint, but less than the highly mobile synovial joint.
Where are the epiphyseal plates?
The Epiphyseal Plate and Growth in Length of a Bone. The power to increase the length of a bone is concentrated in the cartilaginous epiphyseal plates located near each end of the bone. These plates are situated between the shaft of the bone and the secondary ossification centers within the epiphyses.
What is epiphyseal plate made of?
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.
How do you remember the zones of the epiphyseal plate?
A mnemonic for remembering the names of the epiphyseal plate growth zones is ” Real People Have Career Options,” standing for: Resting zone, Proliferative zone, Hypertrophic cartilage zone, Calcified cartilage zone, Ossification zone.
What is the difference between symphysis and synchondrosis joints?
The key difference between synchondrosis and symphysis is that synchondrosis is a cartilaginous joint where bones are joined by hyaline cartilage, while symphysis is a cartilaginous joint where bones are joined by fibrocartilage. There are cartilaginous joints between bones.
Where is epiphysis of the bone?
The epiphysis lies between the growth plate (physis) and the joint at the end of the bone (Figure 8). 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.
What type of bone is in the epiphyseal line?
The structure indicated is the epiphyseal line. The epiphyseal plate is a plate of hyaline cartilage found in children and adolescents, located in the metaphysis at the ends of each long bone. Long bones consist of a diaphysis, metaphysis and epiphysis.
Is epiphyseal growth plate a joint?
What joints are cartilaginous joints?
cartilaginous joints
- ball and socket joint.
- hinge joint.
- condyloid joint.
- saddle joint.
- pivot joint.
- plane joint.
What is an epiphyseal plate and its function?
The epiphyseal growth plate is the main site of longitudinal growth of the long bones. At this site, cartilage is formed by the proliferation and hypertrophy of cells and synthesis of the typical extracellular matrix. The formed cartilage is then calcified, degraded, and replaced by osseous tissue.
Do all bones have an epiphyseal plate?
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 an epiphyseal disc?
What is the role of the epiphyseal disk? A disk of cartilage at the junction of the diaphysis and epiphyses of growing long bones. Cartilage synthesis provides for growth in length; eventually the cartilage is replaced by bone.
What disease is caused from thick epiphyseal plates?
– Level 1: COMP (exons 10–15) and MATN3 (exon 2) – Level 2: COMP (exons 8 & 9 and 16–19) – Level 3: COL9A1 (exon 8), COL9A2 and COL9A3 (exon 3)
