Evoking the displeasure of getting a good sniff of fresh vomit, the “vomer” is actually a description of the part of the small bone in the nose where the sensory cells sit.
This causes the vomer bone, which runs through the nasal passages to the mouth, to rock back and forth, says Lisa DeStefano, D.O., an assistant professor at the Michigan State University college of osteopathic medicine.
We examined the shape of the arch above the vomer (when holding the skull upside down).
Again, a line drawn through the axis of the face, between the bones called ethmoid and vomer — the “basifacial axis” (‘f e’.) forms an exceedingly obtuse angle, where, when produced, it cuts the ‘basicranial axis.’
Also, the vomer itself tends to be boat-shaped in Salvelinus, but not in Oncorhynchus or Salmo.
For example, vomerine teeth—that is, those on the vomer bone in the center of the roof of the mouth—occur in two well-developed rows along the length of the vomer in Oncorhynchus and Salmo, but only in a small patch at the front of the vomer in Salvelinus.
Also, Salvelinus species have teeth only on the anterior part of the vomer the narrow bone in the roof of the mouth, whereas Salmo and Oncorhynchus have teeth on both the head and shaft of the vomer.
The white infant comes into the world with its brain inclosed by fifteen disunited bony plates -- the occipital bone being divided into four parts, the sphenoid into three, the frontal into two, each of the two temporals into two, which, with the two parietals, make fifteen plates in all -- the vomer and ethmoid not being ossified at birth.
The vomer serves as a thin and delicate partition between the two cavities of the nose.
The teeth on the vomer and tongue often disappear. (_d_.)
