Human Skeletal System Concepts

The video introduces the skeletal system, explaining its role in forming the body's framework and comprising 20% of an adult's weight. It consists of bones and connective tissues like cartilage, joints, tendons, and ligaments. The bones are divided into the axial skeleton, which protects internal organs, and the appendicular skeleton, which aids movement. Differences between male and female skeletons are highlighted, such as bone mass and pelvis structure. The video concludes with a brief overview of connective tissues and their functions.
