Nutrient artery
NUTRIENT ARTERY IN BONES
Arteria nutricia; Arteria nutriens; Nutrient foramina; Nutrient arteries; Nutrient vein
The nutrient artery (arteria nutricia, or medullary), usually accompanied by one or two veins, enters the bone through the nutrient foramen, runs obliquely through the cortex, sends branches upward and downward to the bone marrow, which ramify in the endosteum–the vascular membrane lining the medullary cavity–and give twigs to the adjoining canals. Nutrient arteries are the most apparent blood vessels of the bones.
