| canalis adductorius | The space in middle third of the thigh between the vastus medialis and adductor muscles, converted into a canal by the overlying sartorius muscle. It gives passage to the femoral vessels and saphenous nerve, ending at the adductor hiatus. Synonym: canalis adductorius, Hunter's canal, subsartorial canal. (05 Mar 2000) |

| canalis analis | The terminal portion of the alimentary canal; it extends from the pelvic diaphragm to the anal orifice. Synonym: canalis analis. (05 Mar 2000) |
| canalis caroticus | A passage through the petrous part of the temporal bone from its inferior surface upward, medially, and forward to the apex where it opens into the foramen lacerum. It transmits the internal carotid artery and plexuses of veins and autonomic nerves. Synonym: canalis caroticus. (05 Mar 2000) |
| canalis carpi | The passageway deep to the transverse carpal ligament between tubercles of the scaphoid and trapezoid bones on the radial side and the pisiform and hook of the hamate on the ulnar side, through which the median nerve and the flexor tendons of the fingers and thumb pass; compression of the median nerve may occur here (carpal tunnel syndrome). Synonym: canalis carpi, carpal canal. (05 Mar 2000) |
| canalis centralis medullae spinalis | The ependyma-lined lumen (cavity) of the neural tube, the cerebral part of which remains patent to form the ventricles of the brain, while the spinal part in the adult often is reduced to a solid strand of modified ependyma. Synonym: canalis centralis medullae spinalis, central canal of spinal cord, tubus medullaris. Synonym: syringocele. (05 Mar 2000) |
| canalis cervicis uteri | A fusiform canal extending from the isthmus of the uterus to the opening of the uterus into the vagina. Synonym: canalis cervicis uteri. (05 Mar 2000) |
| canalis condylaris | The inconstant opening through the occipital bone posterior to the condyle on each side that transmits the occipital emissary vein. Synonym: canalis condylaris, posterior condyloid foramen. (05 Mar 2000) |
| canalis femoralis | The medial compartment of the femoral sheath. Synonym: canalis femoralis. (05 Mar 2000) |
| canalis gastrici | Furrow formed temporarily between longitudinal rugae of the gastric mucosa along the lesser curvature during swallowing; observed radiographically and endoscopically, it is formed because of the firm attachment of the gastric mucosa to the muscular layer, which is devoid of an oblique layer at this site; said to form a passageway favoured by saliva and small quantities of masticated food and other fluids as they flow from cardia to gastroduodenal junction. Synonym: canalis gastricus, canalis gastrici, magenstrasse. (05 Mar 2000) |

| canalis hyaloideus | A minute canal running through the vitreous from the discus nervi optici to the lens, containing in foetal life a prolongation of the central artery of the retina, the hyaloid artery. See: vitreous, hyaloid artery. Synonym: canalis hyaloideus, central canal of the vitreous, Cloquet's canal, Stilling's canal. (05 Mar 2000) |
| canalis hypoglossalis | The canal through which the hypoglossal nerve emerges from the skull. Synonym: canalis hypoglossalis, anterior condyloid canal of occipital bone, anterior condyloid foramen. (05 Mar 2000) |
| canalis incisivus | incisive canal |
| canalis infraorbitalis | A canal running beneath the orbital margin of the maxilla from the infraorbital groove, in the floor of the orbit, to the infraorbital foramen; it transmits the infraorbital artery and nerve. Synonym: canalis infraorbitalis. (05 Mar 2000) |
| canalis mandibulae | The canal within the mandible that transmits the inferior alveolar nerve and vessels. Its posterior opening is the mandibular foramen. Synonym: canalis mandibulae, inferior dental canal. (05 Mar 2000) |
