Joints Lecture Fully Explained | Ball And Socket And Hinge Joints | Class 12 Urdu Hindi

Hi Everyone! Welcome To My Channel "Ali Academy Biology Lectures"

About This Video ........................

In This Video Lecture You Will Learn Basic Concept Of Joints
Joints occur where bones meet. They not only hold our skeleton together, but also give it the mobility.
(i) Immovable joints (ii) Slightly movable joints (iii) Freely movable joints
Joints are classiied on the basis of the amount of movement allowed by them, into three categories:
The freely movable joints are of two types viz. hinge joint and ball and socket joint.
Joints are also classiied on the basis of structure:
between the moving joints. The joint is surrounded by a layer of connective tissue called “ibrous
knee. At these joints, pair of muscles are arranged in the same plane as that of joints. One end of
between growing bone. The bones held together by ibrous cartilage are found between vertebrae
3. Synovial Joints:These joints contain a cavity illed with luid and are adapted to reduce friction
form distinct ligament, holding the bones together.
Based on structure and movements allowed, the synovial joints can be classiied further into major
capsule” and their inner layer the synovial membrane. Some parts of capsule may be modiied to
categories.
each muscle, the origin is ixed to the immovable bone on one side of joint and the other end of
1. Fibrous Joints: These joints are held together by short collagen ibers embedded in connective
2. Cartilaginous Joints:These joints allow little or no movement. Hyaline cartilage forms joint
tissue. Such joints are present in the skull, and they ix teeth into the jaw.
at the point where coxal bones meet in front of the pelvis.
(i) Hinge Joint : The joint that allows the movements in two directions. These are at elbow and
muscles, the insertion is attached to the far side of the joint.

About This Channel.....................

I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
