Modified conductive cardiomyocytes that line the ventricular septum within the endocardium are called?
Pukinje fibers
in relation to the lumen, arterioles have?
thick tunica medias
Continuous, fenestrated, and discontinuous are used to describe arterioles?
false. these are capillaries.
this type of capillary has a continuous basal membrane with holes in the cytoplasm and cell membrane
Fenestrated
this type of capillary has an intact cell membrane and basement membrane that is continuous throughout
Continuous
Fenestrated capillaries are characteristic of endocrine glands and where else?
Renal glomerular capillaries
This type of capillary can be found in the liver and spleen
discontinuous capillaries
