Skeletal System Flashcards
Outer covering of bone, connective tissue, contains blood lymph and nerves
Periosteum
End of each bone
Epiphyses
Bone that runs between two ends of the long bone?
Diaphysis
Inside the diaphysis-contains bone marrow-lined thin vascular membrane
Endosteum
Thin band of cartridge, growth plate,
Epiphyseal
Found in epiphysis and produced red blood cells?
Red bone marrow
High in fat, found in diaphysis, can be converted to red bone marrow to increase rbc production in blood loss
Yellow bone marrow
Made of connective tissue, holds bones within joints
Ligaments
Smooth elastic tissue, acts as shock absorber and reduces friction within joints
Cartridge
Bones located in centre of body ie skull, thorax and spinal column
Axial skeleton
Bones located in apendages eg pelvis arms legs
Appendicular skeleton
Bones found in arms and legs and are longer then they are wide
Long bones
Found in wrists and ankles, similar width and length
Short bones
Thinner bones, flat or curved found in ribs sternum scapula ( plate liked )
Flat bones
Oddly shaped bones form connections between other bones, found in vertebrae and hipbone
Irregular bones
Contains osteon, hard dense tissue , usually forms the shafts or long bones and outer layer of other bones
Compact bone
Makes bones lighter and provides space for red bone marrow
Spongy bone
Acts as attachments points for muscles , ligaments or tendons
Projecting structures
Acts as pathways for nerves and blood vessels
Depressions
Productions of rbc and wbc
Haematopoiesis/ hemopoiesis
Production of rbc
Erythropoiesis
What happens in response to low oxygen levels in the blood? Hypoxia
Haematopoiesis increases when erythropoietin secretion increases
Formation of bone
Osteogenesis
Found in periosteum , endosteum and central canal of compact bones! Can become osteoblasts when needed
Osteoprogenitor cells
