|---|---|
| hamulus of spiral lamina | The upper hooklike termination of the bony spiral lamina at the apex of the cochlea. Synonym: hamulus laminae spiralis, hamulus cochleae, hook of spiral lamina. (05 Mar 2000) |
| proximal spiral septum | See: spiral septum. (05 Mar 2000) |
| secondary spiral lamina | A ridge on the outer wall of the first turn of the cochlea opposite the spiral lamina. Synonym: lamina spiralis secundaria, secondary spiral plate. (05 Mar 2000) |
| secondary spiral plate | A ridge on the outer wall of the first turn of the cochlea opposite the spiral lamina. Synonym: lamina spiralis secundaria, secondary spiral plate. (05 Mar 2000) |
| hook of spiral lamina | The upper hooklike termination of the bony spiral lamina at the apex of the cochlea. Synonym: hamulus laminae spiralis, hamulus cochleae, hook of spiral lamina. (05 Mar 2000) |
| spiral | Of leaves or floral organs, borne at different levels on the main stem, in an ascending spiral. Compare: cyclic. (09 Oct 1997) |
| spiral and curved bacteria | A large, very diverse group of bacteria in which some species are curved, some helical. (12 Dec 1998) |

| spiral bandage | An oblique bandage encircling a limb, the successive turns overlapping those preceding. (05 Mar 2000) |
| spiral bulbar septum | See: spiral septum. (05 Mar 2000) |
| spiral canal of cochlea | The winding tube of the bony labyrinth which makes two and a half turns about the modiolus of the cochlea; it is divided incompletely into two compartments by a winding shelf of bone, the bony spiral lamina. Synonym: canalis spiralis cochleae, Rosenthal's canal, spiral canal of cochlea. (05 Mar 2000) |
| spiral canal of modiolus | <anatomy> The space in the modiolus in which the spiral ganglion of the cochlear nerve lies. Synonym: canalis spiralis modioli. (05 Mar 2000) |
| spiral cleavage | <marine biology> Pattern of early cleavage found in molluscs and annelids (both mosaic eggs). The animal pole blastomeres are rotated with respect to those of the vegetal pole. The handedness of the spiral twist is maternally inherited. (18 Nov 1997) |
| spiral cochlear ganglion | An elongated ganglion of bipolar sensory nerve cell bodies on the cochlear part of the vestibulocochlear nerve in the spiral canal of the modiolus; each ganglion cell gives rise to a peripheral process that passes between the layers of the bony spiral lamina to the organ of Corti, and a central axon that enters the hindbrain as a component of the inferior (cochlear) root of the eighth nerve. Synonym: ganglion spirale cochleae, auditory ganglion, cochlear ganglion, Corti's ganglion, spiral cochlear ganglion. (05 Mar 2000) |
