Bone. Light micrograph of a section through the neurovascular channels (white circles) in cortical (compact) bone. These channels, also known as Haversian canals or osteonic canals, transport nutrients to the bone via the capillaries that run down the channels. The channels also contain nerve fibres. Cells contained within Haversian canals are called osteocytes (not shown). Many Haversian systems are arranged in columns running down the long axis of the bone. Mag: x115 when 10cm wide.
