SKELETAL SYSTEM Flashcards
Components of Skeletal system
BONES, CARTILAGES, TENDONS, LIGAMENTS
Skeletal system function
SUPPORT, PROTECT, MOVEMENT, STORAGE, BLOOD CELL PRODUCTION
CONNECTIVE TISSUES
Bones, cartilage, tendons, ligaments
Are largely determined by the composition of their extracellular matrix. Contains collagen, ground substance, and other organic molecules as well as minerals
EXTRACELLULAR MATRIX
Tough, ropelike protein
COLLAGEN
Tough, ropelike protein
COLLAGEN
Are large molecules consisting of many polysaccharides attaching to and encircling core proteins. Form large aggregates and attract water.
PROTEOGLYCANS
Makes cartilage tough
COLLAGEN
Makes cartilage tough
COLLAGEN
Makes cartilage smooth and resilient
WATER-FILLED PROTEOGLYCANS
Are longer than they are wide.
Ex. Upper and lower limb bones
LONG BONES
Are approximately as wide as they long.
Ex. Bones of the wrist and ankle
SHORT BONES
Have relatively thin, flattened shape
Ex. Bones of the skull and sternum
FLAT BONES
Include the vertebrae and facial bones, which have shapes that do not fit readily into the other categories
IRREGULAR BONES
LONG BONE STRUCTURE
Shaft
