This note provides us the information about skeletal system, functions of the skeletal system and structure of bones. Learn More

Trunk consists of bones of the vertebral column and the thorax. The vertebral column supports the head, helps in upright posture and locomotion. The first cervical vertebra is called atlas which supports the globe-like head.This note provides us the information about axial skeleton and information about types of bones or bones of the tr Learn More
