Nerve fibers in bones sense pain, regulate blood supplies, and aid in bone growth. Blood vessels enter bones through nutrient foramina to nourish bone regions. Periosteum plays a crucial role in bone nourishment.
Nerve fibers follow paths into the bone, concentrating in metabolically active regions, sensing pain, regulating blood supplies, and influencing bone growth. Blood vessels enter bones through nutrient foramina to nourish spongy and medullary regions, and pass through Haversian canals to nourish bone interiors. Periosteum, rich in blood supply and nociceptors, covers bone surfaces, providing nourishment.
