QuestionAnswer What are the main functions of the skeletal system? The main functions of the skeletal system include providing support and shape to the body, protecting vital organs, allowing movement through attachment points for muscles, storing minerals like calcium and phosphorus, and producing blood cells in the bone marrow. Which bones are part of the axial skeleton? The axial skeleton includes the skull, vertebral column, and the thoracic cage (ribs and sternum). What is the difference between compact and spongy bone? Compact bone is dense and solid, providing strength and structure, while spongy bone has a porous, honeycomb-like structure that helps reduce weight and supports bone marrow. How many bones are in the adult human skeletal system? An adult human skeletal system typically consists of 206 bones. What is the role of cartilage in the skeletal system? Cartilage provides flexible support and reduces friction between bones at joints, as well as shaping structures like the ear and nose. Name three types of joints and give an example of each. The three types of joints are: fibrous joints (sutures in the skull), cartilaginous joints (pubic symphysis), and synovial joints (knee and elbow). Why are bones considered living tissues? Bones are considered living tissues because they contain cells that grow, repair, and remodel the bone throughout life in response to stress and injury.
