I WONDER - What Are The Different Types Of Joints?

The video tutorial explains the different types of joints in the human body, including ellipsoidal, gliding, and hinge joints. It describes how these joints connect bones and allow various movements. Ellipsoidal joints, found in knuckles and wrists, enable bending and extending. Gliding joints, located in the spine and ankles, allow bones to glide past each other. Hinge joints, like those in knees and elbows, permit movement in one direction, similar to door hinges.
