A
false
Never say fetal mesenchyme,
mesenchyme is an Embryonic tissue
2
Q

large veins often do
(but less than arteries)
3
Q

4
Q
this provides proprioception in muscle tissue
A
muscle spindle (and golgi tendon organ at musculotendinous junction)
5
Q
what are some key histological features of myocardial infarction?
A
waviness necrosis edema hemorrhage neutrophilic infiltrate dying neutrophils phagocytosis granulation tissue (rich in new vasculature) collagen deposition collagen scar
6
Q
what is granulation tissue?
A
connective tissue rich in new vasculature
e.g. after myocardial infarction
