| apertura externa canaliculi cochleae | The external opening of the cochlear aqueduct on the temporal bone medial to the jugular fossa. Synonym: apertura externa canaliculi cochleae. (05 Mar 2000) |
| apertura tympanica canaliculi chordae tympani | The small canal opening found lateral to the pyramidal eminence in the posterior wall of the middle ear cavity from which the chorda tympani nerve emerges to pass anteriorly between the ossicles accompanied by a branch of the stylomastoid artery. Synonym: apertura tympanica canaliculi chordae tympani. (05 Mar 2000) |
| bile canaliculi | Minute intercellular channels that occur between liver cells and carry bile towards interlobar bile ducts. Also called bile capillaries. (12 Dec 1998) |
| canaliculi | In bone, channels that run through the calcified matrix between lacunae containing osteocytes. In liver, small channels between hepatocytes through which bile flows to the bile duct and thence to the intestinal lumen. (18 Nov 1997) |
| canaliculi caroticotympanici | Small openings within the carotid canal that afford passage to the tympanic cavity of branches of the internal carotid artery and carotid sympathetic plexus. Synonym: canaliculi caroticotympanici. (05 Mar 2000) |
| canaliculi dentales | Minute, wavy, branching tubes or canals in the dentin; they contain the long cytoplasmic processes of odontoblasts and extend radially from the pulp to the dentoenamel junction. Synonym: dental tubules, dentinal canals, dentinal tubules, tubuli dentales. (05 Mar 2000) |
| vena canaliculi cochleae | It drains the cochlea, sacculus, and part of the utricules, and empties into the superior bulb of the jugular vein by accompanying the perilymphatic duct through the cochlear canaliculus. Synonym: vena aqueductus cochleae, vein of cochlear aqueduct, vena canaliculi cochleae. (05 Mar 2000) |
| caroticotympanic canaliculi | Small openings within the carotid canal that afford passage to the tympanic cavity of branches of the internal carotid artery and carotid sympathetic plexus. Synonym: canaliculi caroticotympanici. (05 Mar 2000) |
| Thiersch's canaliculi | Minute channels in newly formed reparative tissue, permitting the circulation of nutritive fluids, precursors of new vascularization. (05 Mar 2000) |
| tympanic opening of canaliculi for chorda tympani | The small canal opening found lateral to the pyramidal eminence in the posterior wall of the middle ear cavity from which the chorda tympani nerve emerges to pass anteriorly between the ossicles accompanied by a branch of the stylomastoid artery. Synonym: apertura tympanica canaliculi chordae tympani. (05 Mar 2000) |
| arrector pili | A microscopic band of muscle tissue which connects a hair follicle to the dermis. When stimulated, the arrector pili will contract and cause the hair to become more perpendicular to the skin surface (stand on end). (12 Dec 1998) |
| arrector pili muscles | Bundles of smooth muscle fibres, attached to the deep part of the hair follicles, passing outward alongside the sebaceous glands to the papillary layer of the corium; they act to pull the hairs erect, causing "goose bumps" or "goose flesh" (cutis anserina). Synonym: musculi arrectores pilorum, arrectores pilorum, erector muscles of hairs. (05 Mar 2000) |
| bulbus pili | Hair bulb, the lower expanded extremity of the hair follicle that fits like a cap over the papilla pili. Synonym: bulbus pili, hair bulb. (05 Mar 2000) |
| radix pili | The part of a hair that is embedded in the hair follicle, its lower succulent extremity capping the dermal papilla pili in the deep bulbous portion of the follicle. Synonym: radix pili. (05 Mar 2000) |
