JOINTS
● `color{violet}("Joints")` are essential for all types of movements involving the `color{violet}("bony parts")` of the `color{violet}("body.")`
● `color{violet}("Locomotory")` movements are no exception to this.
● `color{violet}("Joints")` are points of contact `color{brown}("between bones,")` or between `color{brown}("bones and cartilages.")`
● Force generated by the `color{violet}("muscles")` is used to carry out movement through joints, where the `color{violet}("joint acts")` as a `color{brown}("fulcrum.")`
● The `color{violet}("movability")` at these joints vary depending on `color{violet}("different factors.")`
● Joints have been classified into three major structural forms, namely, `color{brown}("fibrous, cartilaginous and synovial.")`
`star` `color{green}("Fibrous Joints:")`
● `color{brown}("Fibrous joints")` do not allow any movement.
● This type of joint is shown by the `color{brown}("flat skull bones")` which fuse end-to-end with the help of `color{violet}("dense fibrous")` connective tissues in the form of sutures, to form the `color{violet}("cranium.")`
`star` `color{green}("Cartilaginous Joints:")`
● In `color{brown}("cartilaginous joints,")` the `color{violet}("bones")` involved are joined together with the help of `color{violet}("cartilages.")`
● The joint between the `color{brown}("adjacent")` vertebrae in the vertebral column is of this pattern and it `color{violet}("permits limited movements.")`
`star` `color{green}("Synovial Joints:")`
● `color{violet}("Synovial joints")` are characterised by the presence of a fluid filled `color{brown}("synovial cavity")` between the articulating surfaces of the `color{violet}("two bones.")`
● Such an arrangement allows `color{violet}("considerable movement.")`
● These joints help in `color{violet}("locomotion")` and many other movements.
● Some of the examples are:
`star` `color{brown}("Ball and socket joint")` (between humerus and pectoral girdle),
`star` `color{brown}("Hinge joint")` (knee joint),
`star` `color{brown}("Pivot joint")` (between atlas and axis),
`star` `color{brown}("Gliding joint")` (between the carpals) and
`star` `color{brown}("Saddle joint")` (between carpal and metacarpal of thumb).
