Exam review Flashcards
3 skeletal supports, where, and their proteints
- microfilament - membrane - actin
- intermediate filaments- support - varied
- microtubules - cilia - protein dimers
chondroitin sulfate and keratin protein in collagen matrix
aggrecan
what tells progenitor cells to become osteoblasdt
CBFA1
what maintains patency in alveoli
elastin fibers
calcium binding protein in muscle cells
troponin
layers covering inner and outer sides of bone
endosteum and periosteum
zones which indicate interstitial growth
Proliferation and hypertrophy
cell layer that replaces cells in trachea
basal cell layer
cell layer that replaces cells in bronchiole
clara cells
organelle that causes nissel substnace
rough ER
discs between cardiac muscles
intercalcated discs
What is the embryonic origin of epithelioreticular cells
endoderm of 3rd pharyngeal pouch
proteins associated with thick filament
myosin
proteins assoc with thin filament
actin, troponin, tropomyosin
what makes A band dark
thick and thin filaments overlap
what make I band ight
only thin bands
replacement of troponin in smooth muscle
caldesmon
where ependyma occur
choroid plexus
line the ventricles
3 types of neurons and where
- multipolar - autonomic ganglia
- pseudounipolar - sensory
- bipolar
4 glia of CNS and what they do
- ogliodendrites - myelin formation
- astrocytes - anchor and scavenge ions and transmitters
- ependyma - line ventricle and produce CSF
- microglia - phagocytose
4 layers of skin and associated proteins
- stratum basale - none
- stratum spinosum - thin filaments of cytokeratin
- stratum granulosum - keratohyaline which mixes with cytokeratin
- stratum corneum - keratine
3 things mast cells secrete
histamine, ECF, NCF
2 types of cart. growth
- interstitial
2. appositional
signal for progentiors of blasts and clasts
blasts - CBFA1
clast - G-CSF and RANKL
cell signal for start of intramembranous ossification
G-CSF
what stimulates penetration of vessels in new bone
VEGF
what stimulates chondroblast activity
PTHrP
2 main types of bone growth
- intramembranous - progenitor cells
2. endochondral - replace old cart.
pressure at both ends of cap
arterial end - hydrostatic
venule - osmotic
