Skeletal system Flashcards
Anatomy
Skeletal system
Network of bones, joints, and connective tissue
Long bones
Tubular shape with expanded ends
( Femur, Humerus )
Short Bones
Cube shaped, with similar lengths and widths
( wrist [CARPLES]and ankles [TARSALS] )
Flat Bones
Thin flat surfaces
( skull, scapulae, and ribs )
Irregular bones
Complex shaped bones ( does not fit in with the other bones )
( vertebrae and facial bones )
Sesamoid bones
small bones rounded
( Patella [ kneecap] and joints )
Wormian Bones
small bones found in between cranial bones
Bone composition
Bone made of minerals
(Calcium phosphorus Collagen fibers living cells )
Osteogenesis
the development of bones
( Bones undergo a constant process of formation )
Osteoblasts
Builds bone tissue
Osteoclasts
break down bone tissue in a process called bone remolding
The balance between osteoblasts and osteoclasts does what ?
maintain bone density and shape
Epiphyseal plate
longitudinal ( lengthwise) growth
joints
interactions between two or more bones, muscles, and connective tissues
Joint structure
joints are when two or more bones meet
( FIBRAS, CARTILAGINOUS, AND SYNOVIAL)
