Blood and Nerve Supply
periosteal veins
accompany periosteal arteries and exit via the periosteum
nerves
accompany BV that supply bones. Periosteum is rich in sensory nerves, some of which carry sensation of pain; a result of tearing or tension.
epiphyseal and metaphyseal veins
accompany their respective arteries and exit through the epiphyses and metaphyses.
Arteries
carries blood TO bone tissue
Veins
carries blood away from bone tissue
epiphyseal artery
enter the epiphyseal
nutrient arteries
found near the center of the diaphysis
Bone Marrow Biopsy
needle inserted into middle of the bone for a sample of red bone marrow to examine it for leukemia, metastatic neoplasm (tumors), lymphoma, Hodgkin's and aplastic anemia. Pain is only felt as the needle penetrates the periosteum. Once through, there is little pain.
nutrient veins
one or two veins will accompany the nutrient artery and exit the diaphysis
periosteal arteries
small arteries accompanied by nerves; enter diaphysis of the bone through perforating (Volkmann's canals)
metaphyseal artery functions
supply bone tissue of the metaphyses & red marrow
nutrient arteries function
supply inner compact bone tissue of diaphysis and spongy bone tissue and red bone marrow as far as the epiphyseal plates (lines)
function of periosteal arteries
supply periosteum and outer part of compact bone.
epiphyseal artery functions
supply red marrow and the bone tissue of the epiphyses
metaphyseal artery
the metapyses of a long bone (together with the nutrient artery)
