tissues
what is the definition of tissue?
groups of cells that have a common origin and function
what are the three types of loose connective tissue?
areolar - subcutaneous skin, surrounding blood vessels
adipose- found every where areolar is
white adipose- increased blood vessels
brown adipose- good
reticular- forms stroma of organs
supports binds and filters
what are the 6 functions of bone?
support
protection
assistance in movement
mineral storage and release
blood cell production
triglyceride storage
what is the formation of bone called?
osteogenesis
what is a fissure
narrow slit between adjacent parts, nerves and blood vessel
label the different cell shapes and arrangement of epithelial tissue layers.
the three types of dense connective tissue?
regular- forms tendons and ligaments and aponeuroses
irregular - forms sheets of fascia , tensile stress( tension)
elastic- lungs
what are the different types of bones and give examples?
long bones - humorous
short bones - carpal bones
irregular bones- vertebrae
flat bones - frontal bone
sesamoid bone- patella
why do we need to increase bone length and width?
to make them bigger and stronger, to support the weight of the body and be able to perform daily task.
fossa
what are the functions of microvilli and cilia?
microvilli- absorption, usually found in digestive tract
Cilia- lines the respiratory, helps capture and push debris
if a bone breaks how does it create new bone?
osteoprogenitor
osteoblast
osteocyte
osteoblast
what are the two organizational level of bone?
cortical, compact bone - parallel bone
spongy/ trabecular bone - inferior of bone
unorganized/lacuna - makes bone light weight
before the plates of bone close what is mainly in the place of bone?
cartilage- in the epiphyseal plate
meatus
passageway, tube like opening
what does mesenchyme become?
proper connective tissue - loose and dense
supportive connective tissue- cartilage, bone
liquid connective tissue- blood and lymph
what are the three types of cartilage? Put them in order from least to most rigid.
hyaline/ articular- most abundant , ends of long bones , joint movement
fibrocartilage- disk, pubic symphysis , rigid
elastic- epiglottis, part of external ear, shape, elastic
what is the external structure of bone?
diaphysis- the main long part of the bone
metaphysis- middle part newer bone
epiphyses- the ends of bone, epiphyseal plate and line
how is bone added?
it is added onto the outside( appositional growth)
the inside then gets broken down ( osteocytes)
large round protuberance with smooth articular surface at end of bone
condyles
what is the main function of group substance?
supports, binds and maintains health of connective tissue
Glycosaminoglycans- traps water
hyaluronic acid
chondroitin sulfate
fibronectin
what are the membranes of the thoracic cavity and the abdominopelvic cavity?
lungs - pleura
heart- pericardium
abdomin- peritoneum
label the different parts of bone.

what are the stages of bone growth
three-
prenatal0 endochondral( hyaline cartilage to bone , intramembranous ( mesenchymal to bone)
child and adolescent growth
mature adult bone- remodeling
spinous process, where will I find
sharp, slender projection, vertebrae
