midterm anaphy Flashcards
- red bone marrow produce red blood cells, hematopoiesis produce white blood cells and platelets
blood cell production
- distal and proximal ends of the bone
epiphysis
- provides structural framework and shape, supporting soft tissues, provides attachment of most skeletal muscles
support
- hollow space within the diaphysis– contains yellow bone marrow
medullary cavity
contains haversian canal, contains blood vessels, nerve and lymphatic vessels
haversian system
- does not contain osteons
- red bone marrow is present
spongy bone
- bone forms within hyaline cartilage, that develops from mesenchyme
endochondral ossification
- projections that form joints and attachment points for connective tissue
processes
- bone forms directly within loose fibrous connective tissue (mesenchyme) arranged in sheetlike layers that resemble membranes
intramembranous ossification
- bone tissue stores calcium and phosphorus, releases minerals into the blood to maintain homeostasis
mineral growth factor stage
- nearly equal length and width, wrist and ankle bones
short
- complex shapes, vertebrae, some facial bones
irregular
- skeleton protects many internal organs from injury
protection
- main cells of bone tissue, and maintain its daily metabolism, does not undergo cell division
osteocytes
- thin layer of hyaline cartilage, reduces friction and absorbs shock at freely movable joints– articulation
aricular cartilage
- generally thin, provide protection
flat
- thin membrane that lines the medullary cavity– contains 1 layer of bone-forming cells
endosteum
enumerate the bone structure
diaphysis, medullary cavity, endosteum, epiphysis, epiphyseal plate, epiphyseal line
enumerate bone surface markings
depression/openings, processes
- contains few spaces, arranged in repeating units
compact bone
- protects the bone, assists in fracture repair, anchors tendons and ligaments
periosteum
- separates diaphysis and epiphysis– region of mitosis
epiphyseal plate
- replaces epiphysial plate when bone growth is completed
epiphyseal line
stores calcium & phosphorus, releases minerals into the blood to maintain homeostasis
bone tissue
factors that affect bone growth
heredity, nutrition, hormones, exercise/stress
- red bone marrow produce red blood cells, hematopoiesis produce white blood cells and platelets
blood cell production
- process by which bone forms
- occurs in 6th/7th week of embryonic dev’t
ossification
enumerate bone classification
long, short, flat, irregular
- form joints/ allow passage of blood vessels, nerves, ligaments, tendons
depression/openings
arranged in sheetlike layers that resemble membranes
mesenchyme
- have greater length and width, consists of shaft
long
- skeletal muscle attached to bones, when muscle contract. they pull bones
assisting in movement
- bones shaft/body, long, cylindrical main portion of the bone
diaphysis
