Tissue test Flashcards
5 functions
Support, protection, movement, storage, blood cell production
Support
Bones provide a framework for the support of the body
Protection
Bones protect internal organs
Movement
Bones allow for movement through the contraction of attached muscle tissue.
Storage
Bones provide storage calcium and minerals
Blood cell production
Hematopoiesis creates red blood cells, white blood cells, and platelets.
Osteoclasts
Break down the bone tissue
Osteoblasts
Create bone tissue
Axial skeleton
Skull, hyoid bone, vertebral column, thoracic cage
Skull
Cranium, facial bones
Vertebral column
Vertebrae, sacrum, coccyx
Thoracic cage
Ribs,sternum
Appendicular skeleton
Pectoral girdle, upper limba, pelvic girdle, lower limba
Pectoral girdle
Scapula, clavical
Upper limba
Humerus, radius, ulna, carpals, metacarpals, phalanges
Pelvic girdle
Two coxa
Lower limba
Femur, tibia, fibula, patella, tarsals, metatarsals, phalanges.
Long bones
Long longitudinal axis and extended ends
Short bones
Cuboidal; sides are all roughly equal
Flat bones
Plate like with broad surface
Irregular bones
Variety of shape
Sesamoid bone
Roundish; embedded in tendons
Osseous tissue
Bone tissue. Consists of hard calcium and mineral compounds and collagen fibers.
Diaphysis
Central shaft
Epiphysis
Expanded ends
Medullary cavity
Central cavity of the diaphysis, where yellow marrow is found.
Compact bone
Solid bone found in the diaphysis of long bones and surface of the epiphysis, covering the spongy bone.
Spongy bone
Porous bone in the epiphysis of the long bone. Where red marrow is found and the red blood cells are produced.
