- n. plural In ornithology, the tectrices or coverts of the wing or tail. See tectrices.
- n. In anatomy, the roof of the tympanic cavity of the ear, especially in early stages of its formation: also distinguished as tegmen tympani.
- n. The covering of the posterior wing of some insects; especially, the fore wing of any orthopterous insect, corresponding to the elytrum of a beetle or the hemielytrum of a bug.
Illa cadens tegmen manibus decussit, et una perniciem immisit miseris mortalibus atram.
It vibroverberates upon the tegmen and prosplodes from pomoeria.
The Tegmental Wall or Roof (paries tegmentalis) is formed by a thin plate of bone, the tegmen tympani, which separates the cranial and tympanic cavities.
The semicanal for the Tensor tympani (semicanalis m. tensoris tympani) is the superior and the smaller of the two; it is cylindrical and lies beneath the tegmen tympani.
The tympanic antrum is bounded above by a thin plate of bone, the tegmen tympani, which separates it from the middle fossa of the base of the skull; below by the mastoid process; laterally by the squama just below the temporal line, and medially by the lateral semicircular canal of the internal ear which projects into its cavity.
By far the most common source of intra-cranial infection is chronic suppuration of the middle ear and mastoid antrum, the organisms passing from these cavities to the interior of the skull directly through a perforation of the tegmen tympani or of the wall of the sigmoid groove, or being carried in the blood stream by the emissary veins.
# -- This term is applied when the infection involves the dura mater -- a condition which is usually due to the spread of infection from a localised osseous lesion, such as erosion of the tegmen tympani in chronic suppuration of the middle ear, of the wall of the sigmoid groove in mastoid disease, or of the posterior wall of the frontal sinus in suppuration of that cavity.
In cases resulting from a sub-dural abscess in relation to a compound fracture, a sinus phlebitis, or an erosion of the tegmen tympani, an attempt should be made, after exposing this, to purify and drain the meningeal spaces.
Some are due to direct spread from a collection of pus in relation to an erosion of the tegmen tympani, either inside or outside the dura, others to infection carried by the veins, and in this way the infective material reaches the white matter; less frequently infection from the middle ear takes place along the peri-vascular lymph spaces.
