| haversian canals | <anatomy> The small Vascular canal's that run longitudinally in the centre of haversian systems of compact osseous tissue, through which the blood vessels ramify in bone. Synonym: Leeuwenhoek's canals. (05 Mar 2000) |

| haversian | Pertaining to, or discovered by, Clopton Havers, an English physician of the seventeenth century. (01 Mar 1998) |

| haversian lamella | One of the concentric tubular layers of bone surrounding the central canal in an osteon. Synonym: haversian lamella. (05 Mar 2000) |
| haversian spaces | <anatomy> Space's in bone formed by the enlargement of haversian canals. (05 Mar 2000) |
| haversian system | <anatomy> The basic unit of structure of compact bone, comprising a haversian canal and its concentrically arranged lamellae, of which there may be 4 to 20, each 3 to 7 microns thick, in a single haversian system. A haversian canal is a freely anastomosing channel in compact bone containing blood vessels and running longitudinally in the centre of haversian systems of compact osseous tissue. It was originally described by Clopton Havers, an english physician, in 1691. (12 Dec 1998) |
| alveolar canals | Canals in the body of the maxilla that transmit nerves and vessels from the alveolar foramina to the maxillary teeth. Synonym: canales alveolares, alveolodental canals, dental canals. (05 Mar 2000) |
| alveolodental canals | Canals in the body of the maxilla that transmit nerves and vessels from the alveolar foramina to the maxillary teeth. Synonym: canales alveolares, alveolodental canals, dental canals. (05 Mar 2000) |
| ampulla of the saemicircular canals | A circumscribed dilation of one extremity of each of the three bony saemicircular canals, anterior, posterior, and lateral; each contains an ampulla of the saemicircular ducts. Synonym: ampulla ossea, osseous ampulla. (05 Mar 2000) |
| anterior saemicircular canals | The three bony tubes in the labyrinth of the ear within which the membranous saemicircular ducts are located; they lie in planes at right angles to each other and are known as anterior saemicircular canal, posterior saemicircular canal, and lateral saemicircular canal. Synonym: canales saemicirculares ossei. (05 Mar 2000) |
| bony saemicircular canals | The three bony tubes in the labyrinth of the ear within which the membranous saemicircular ducts are located; they lie in planes at right angles to each other and are known as anterior saemicircular canal, posterior saemicircular canal, and lateral saemicircular canal. Synonym: canales saemicirculares ossei. (05 Mar 2000) |
| Breschet's canals | Channels in the diploe that accommodate the diploic veins. Synonym: canales diploici, Breschet's canals. (05 Mar 2000) |
| canals for lesser palatine nerves | Canalis's located in the posterior part of the palatine bone. Synonym: canales palatini minores. (05 Mar 2000) |
| canals of Scarpa | Separate canals for the nasopalatine nerves and vessels. These canals normally fuse to form the incisive canal. (05 Mar 2000) |
| galactophorous canals | The ducts, numbering 15 or 20, which drain the lobes of the mammary gland; they open at the nipple. Synonym: ductus lactiferi, canalicular ducts, galactophore, galactophorous canals, galactophorous ducts, mamillary ducts, mammary ducts, milk ducts, tubuli galactophori, tubuli lactiferi. (05 Mar 2000) |
| central canals of cochlea | Centrally placed channels that convey vessels and nerves to the apical turns of the cochlea. Synonym: canales longitudinales modioli, central canals of cochlea. (05 Mar 2000) |
| Volkmann's canals | Vascular canal's in compact bone that, unlike those of the haversian system, are not surrounded by concentric lamellae of bone; they run for the most part transversely, perforating the lamellae of the haversian system, and communicate with the canal's of that system.
