Skeletal System Functions and Bone Classification Quiz

Functions and Classification of the Skeletal System

• The skeletal system has various functions, including support, protection, movement, storage of minerals and energy, blood cell formation, and hormone production.
• Long bones, short bones, flat bones, and irregular bones are the four main types of bone classification, each with distinct functions and locations in the body.
• Long bones, such as those in the limbs, act as levers to aid in movement.
• Short bones, like those in the wrists and ankles, provide support and stability with limited movement.
• Flat bones, such as the breastbone and ribs, have a large surface area for muscle attachment.
• Irregular bones, like the hip bones and vertebrae, have specialized shapes and structures.
• Bones are made of compact (cortical) bone tissue on the outside and spongy bone tissue on the inside, with distinct structures and functions.
• Compact bone is made of osteons, which are long cylinders filled with salts and collagen fibers, while spongy bone has trabeculae and contains bone marrow.
• Bones have distinct markings on their surfaces, including projections for muscle and ligament attachment, surfaces for joint formation, and depressions and openings for blood vessels and nerves.
• The skeletal system helps maintain homeostasis through hormone production and regulation of blood calcium levels.
• The classification and structure of bones determine their functions in supporting the body and aiding in movement.
• The skeletal system plays a crucial role in the body's overall health and function, making it essential for various physiological processes.
