Question

What joint is synchondrosis ?

Answer 1

A joint can be described as a connection between two bones in our skeletal system.
Joints are sub-divisible into undermentioned categories :
On the basis of the presence of which type tissue joints are divisible into fibrous, cartilaginous or synovial.
On the basis of the degree of movement allowed, joints are divisible into synarthrosis, amphiarthrosis or diarthrosis.

Complete answer:
A fibrous joint can be described as the place in our body where the bones are surrounded by a tough, fibrous tissue. Generally, these joints require strength and stability over range of movement.Fibrous joints can be divisible into groups of sutures, gomphoses and syndesmoses.
A cartilaginous joint can be described as the place in our body where the bones can be observed to be united by fibrocartilage or hyaline cartilage.It can be further divisible into 2 main categories : synchondroses and the symphyses. The former is primary cartilaginous and latter symphysis is the secondary cartilaginous. Synchondroses is the term used when bones are observed to be connected by hyaline cartilage. They are immovable in nature(synarthrosis). An example for this joint is the joint between the diaphysis and epiphysis of a growing long bone.Symphyseal joints can be described as the place where the bones are observed to be united by a layer of fibrocartilage. They are slightly movable in nature (amphiarthrosis). A few examples of this joint are pubic symphysis, and the joints between vertebral bodies.
A synovial joint can be defined by the observation of the fluid-filled joint cavity contained within a fibrous capsule.They are freely movable in nature (diarthrosis). Generally, they are found in ample amounts as it is the most common type of joint found in the body. These joints can be further divisible into categories according to the shape and their articular surfaces and by analysing the movements.
Synovial joints can be sub-classified into several different types, depending on the shape of their articular surfaces and the movements permitted.

Note:
Hinge, saddle, plane are few types of synovial joints. Hinge allows the movement of bone in a particular place. Elbow joint, ankle joint, knee joint are some of its examples.
Saddle – This joint is named so as it is very similar to a saddle on a horse’s back. One of its features is that it has the ability to oppose articular surfaces with a reciprocal concave-convex shape. Carpometacarpal joints is an example of this joint.
Planes can be described as the articular surfaces that are relatively flat, permitting the bones to glide over one another.
E.g. acromioclavicular joint, subtalar joint.
