the canal from the external auditory meatus to the eardrum.
osseous tube in the temporal bone that transmits the facial nerve.

c's of Gartner
in the ventral wall of the vagina; they are remnants of the mesonephric ducts and very variable in their occurrence. Called also ductus epoophori longitudinales.
see haversian canal.
c's of Hering
openings between the bile canaliculi and the cholangioles, the terminal ducts of the biliary duct system. Called also cholangiole.
central canal of the vitreous humor running from the lens to the optic disk.
an opening in the occipital bone, transmitting the hypoglossal nerve and a branch of the posterior meningeal artery; called also anterior condyloid foramen.
a canal running obliquely from the front of the orbit to the side of the muzzle, transmitting the infraorbital vessels and nerve. In the horse it passes through the maxillary sinus.
the oblique passage in the caudal abdominal wall on either side, through which passes the round ligament of the uterus in some females such as the bitch and the spermatic cord in the males.
small and large intestines.
the nasolacrimal canal.
a small canal in the root of a tooth which emerges on the side, rather than the apex. Called also accessory canal.
a passageway within the mandible for conduction of the inferior alveolar vessels and nerve; the inferior alveolar nerve enters the mandibular canal through the mandibular foramen and exits at the mental foramen supplying nerves to the lower cheek teeth in passing.
1. vertebral canal.
2. the cavity, containing marrow, in the diaphysis of a long bone; called also marrow or medullary cavity.
