Examples
“Occupying the spiral canal of the modiolus is the spiral ganglion of the cochlea (ganglion of Corti) (Fig. 933), consisting of bipolar nerve cells, which constitute the cells of origin of this nerve.”

“The modiolus is the conical central axis or pillar of the cochlea.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“The central ones pass down the modiolus and then through the foramina of the tractus spiralis foraminosus or through the foramen centrale into the lateral or outer end of the internal auditory meatus.”
“The cochlear branch subdivides into twelve or fourteen twigs, which traverse the canals in the modiolus, and are distributed, in the form of a capillary net-work, in the lamina spiralis and basilar membrane.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“The veins of the vestibule and semicircular canals accompany the arteries, and, receiving those of the cochlea at the base of the modiolus, unite to form the internal auditory veins which end in the posterior part of the superior petrosal sinus or in the transverse sinus.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“The cochlear nerve (n. cochlearis) divides into numerous filaments at the base of the modiolus; those for the basal and middle coils pass through the foramina in the tractus spiralis foraminosis, those for the apical coil through the canalis centralis, and the nerves bend outward to pass between the lamellæ of the osseous spiral lamina.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“In the recent state a membrane, the basilar membrane, stretches from the free border of this lamina to the outer wall of the bony cochlea and completely separates the canal into two passages, which, however, communicate with each other at the apex of the modiolus by a small opening named the helicotrema.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“As already stated, the osseous spiral lamina extends only part of the distance between the modiolus and the outer wall of the cochlea, while the basilar membrane stretches from its free edge to the outer wall of the cochlea, and completes the roof of the scala tympani.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“From the spiral canal of the modiolus numerous canals pass outward through the osseous spiral lamina as far as its free edge.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
“The osseous spiral lamina (lamina spiralis ossea) is a bony shelf or ledge which projects from the modiolus into the interior of the canal, and, like the canal, takes two-and three-quarter turns around the modiolus.”
X. The Organs of the Senses and the Common Integument. 1d. 4. The Internal Ear or Labyrinth
