Support and Motion Unit-Concept 1: The Skeletal System Study Guide-objectives section

objectives 1-15 of concept 1 skeletal system by Anthony Hernandez

obj. 1) defend the claim that bone is a living organ

bone is made up of four different types of tissues. connective tissue (Bone ‘osseus’ tissue. Cartilage and dense connective tissue cover bones outside surface). Nervous tissue (in its nerves). Epithelial tissue (in its blood vessels, provide nourishment). Muscle tissue (skeletal muscle tissue)

obj. 2a) different functions of the skeletal system: SUPPORT

framework holding up the entire body

obj. 2b) different functions of the skeletal system: PROTECTION

guards the body’s most vital organs, like the skull protecting the brain and rib cage protecting heart and lungs

obj. 2c) different functions of the skeletal system: MOVEMENT

skeletal muscles are connected to bones via tendons and use bones as levers at joints to produce movements

obj. 2d) different functions of the skeletal system:

STORAGE

stores calcium and phosphate, which then are released into the blood when necessary. Can also store energy in the form of fat in yellow bone marrow. blood cell formation=hematopiesis (in red bone marrow of certain bones).

obj. 2e) different functions of the skeletal system: HORMONE PRODUCTION 

critical for helping to maintain homeostasis

obj. 2e) different functions of the skeletal system: HORMONE PRODUCTION EXAMPLE ONE

produces osteocalcin in order to regulate insulin secretion, glucose regulation and energy usage.

obj. 2e) different functions of the skeletal system: HORMONE PRODUCTION EXAMPLE TWO

helps to regulate blood calcium levels
