Cartilaginous Joints
ha de llegir:

Les articulacions cartilaginoses are associated completely via ligament (fibrocartilage or hyaline). Cartilaginous joints permit more development between bones than a stringy joint yet not as much as the very versatile synovial joint. The joint between the manubrium and the sternum is a case of a cartilaginous joint. This kind of joint additionally shapes the development locales of juvenile long bones and the intervertebral circles of the spinal segment.

An impermanent type of joint called an epiphysis (desenvolupament) plate is one where the ligament is changed over into bone before grown-up life. Such joints are found between the epiphyses and diaphyses of long bones, between the occipital and the sphenoid bones, and amid the early years of life, between the petrous segment of the transient and the jugular procedure of the occipital bone. The epiphyseal plate is a hyaline ligament plate in the metaphysis at each finish of a long bone.

There are two sorts of cartilaginous joints. A synchondrosis is a cartilaginous joint where the bones are joined by a hyaline ligament. Likewise named a synchondrosis is places where the bone is joined to a ligament structure, per exemple, between the front end of a rib and the costal ligament of the thoracic pen. The second sort of cartilaginous joint is, where the bones are joined by fibrocartilage.

A synchondrosis is a cartilaginous joint where bones are combined by a hyaline ligament, or where the bone is joined to the hyaline ligament. A synchondrosis might be brief or perpetual. A brief synchondrosis is the epiphyseal plate (development plate) of a becoming long bone. The epiphyseal plate is the area of developing hyaline ligament that joins the diaphysis (shaft) of the issue that remains to be worked out epiphysis (end of the bone). Bone stretching includes the development of the epiphyseal plate ligament and its substitution by bone, which adds to the diaphysis. For a long time amid youth development, the rates of ligament development and bone arrangement are equivalent and along these lines, the epiphyseal plate does not change in general thickness as the bone extends.

Amid the late adolescents and mid-20s, development of the ligament moderates and in the end stops. The epiphyseal plate is then totally supplanted by bone, and the diaphysis and epiphysis segments of the bone breaker together to shape a solitary grown-up bone. This combination of the diaphysis and epiphysis is a synostosis. per tant, the epiphyseal plate is thought to be a transitory synchondrosis. Since ligament is gentler than bone tissue, damage to a becoming long bone can harm the epiphyseal plate ligament, in this manner halting bone development and keeping extra bone extending.

Developing layers of ligament additionally shape synchondrosis that consolidates the Ilium, ischium, and pubic segments of the hip bone amid youth and youthfulness. At the point when body development stops, the ligament vanishes and is supplanted by bone, shaping synostoses and combining the hard segments together into the single hip bone of the grown-up. també, synostoses join the sacral vertebrae that wire together to frame the grown-up sacrum.



A cartilaginous joint where the bones are joined by fibrocartilage is known as a symphysis. Fibrocartilage is extremely solid since it contains various groups of thick collagen strands, accordingly giving it a considerably more prominent capacity to oppose pulling and twisting powers when contrasted and hyaline ligament. This enables symphysis to emphatically join the nearby bones; malgrat això, en qualsevol cas, take into consideration restricted development to happen. conseqüentment, a symphysis is practically named an amphiarthrosis.

The hole isolating the bones at a symphysis might be tight or wide. Cases in which the hole between the bones is tight incorporate the pubic symphysis and the manubriosternal joint. At the pubic symphysis, the public bits of the privilege and left hip bones of the pelvis are combined by fibrocartilage over a limited hole. així, at the manubriosternal joint, fibro cartilage joins the manubrium and body segments of the sternum.

The intervertebral symphysis is a wide symphysis situated between the collections of contiguous vertebrae of the vertebral section. Here a thick cushion of fibro cartilage called an intervertebral plate unequivocally joins the neighboring vertebrae by filling the hole between them. The width of the intervertebral symphysis is imperative since it takes into consideration little developments between the nearby vertebrae. El que és més, the thick intervertebral circle gives padding between the vertebrae, which is essential while conveying substantial articles or amid high-affect exercises, per exemple, running or bouncing.
