Understanding Joints in the Human Body

The video tutorial by Professor Dave explores the structure and function of joints in the human body. It begins with an introduction to joints, explaining their classification by structure and function. The tutorial then delves into the details of fibrous, cartilaginous, and synovial joints, highlighting their characteristics and types. Finally, it covers the various types of joint movements, including gliding, angular, and rotational movements, as well as special movements like supination and pronation.
