    Notes: A dissection table ventilation system that draws air across the cadaver and away from the table top was designed to fit the Shandon-Lipshaw AN-52 dissection table. Each U-shaped unit consists of a pair of hollow collection arms that attach to a collecting manifold at one end. During dissection the manifold is coupled to a central ventilation system through a flexible duct. The air from the table ventilation system is exhausted after passing through a heat recovery system. The unit is raised from the table surface during dissection of the body cavities to increase the efficiency of fume/odor removal. Eight hour exposure data for formaldehyde concentrations are presented. Data were collected from detectors positioned at selected levels above the cadaver during dissection, and above a tray on the table top containing a known volume of 4% formaldehyde or the West Virginia School of Osteopathic Medicine embalming fluid under varying airflow conditions. The results demonstrate that the table ventilation system is effective in reducing exposure to formaldehyde in the dissection laboratory. © 1995 WiIey-Liss, Inc.

    Weight changes of the submandibular glands in the rat resulting from denervationSupported by National Institutes of Health grant 5 T1 GM 1084 03. (1966)

    Notes: In the lingual nerve of the rat, the number of myelinated fibers ranged from 3,215 to 3,744, with diameters ranging from 0.7 to 9.7 μ. The nerves were unimodal with a peak at 2-3 or 3-4 μ. In the chorda tympani, the number of myelinated fibers ranged from 444 to 538, with diameters ranging from 1.1 to 8.7 μ. The nerves were unimodal with a peak at 1-3 μ.Sixteen days after section of the lingual, chordalingual (the lingual nerve distal to the union with chorda tympani) and chorda tympani nerves as well as intracranial section of the facial nerve, significant weight losses were recorded for the submandibular and retrolingual glands. The greatest weight losses occurred after intracranial section of the facial nerve or section of the chordalingual nerve (retrolingual glands lost 42 and 39%, submandibular glands lost 20 and 28% respectively). Intracranial section of the facial nerve demonstrates that the degree of weight loss is correlated with the number of myelinated fibers (1-3 μ diameter) which degenerate, and that the weight loss is not the result of operative damage to the vascular supply of the glands.

    Innervation of feline perineal musculatureSupported by U.S.P.H.S. grant NS06055 and Minnesota Agriculture Experiment Station grant 2618H. (1974)

    Notes: Innervation to muscles of the feline perineum was examined by gross dissection of the sacral nerve plexus and quantitation of efferent and afferent myelinated fibers in selected nerves derived from the plexus. In addition, distribution of muscle fiber sizes and muscle spindle content were determined for muscles innervated by the nerves studied.Efferent myelinated fiber populations were bimodal in nerves innervating muscles with many spindles and unimodal in nerves innervating muscles in which few or no spindles were observed. Coccygeus and levator ani muscles had similar numbers of muscle spindles, but the spindles were different in the two muscles based on afferent innervation. In both coccygeous and external anal sphincter muscles, primary spindle endings must be associated with relatively small afferent nerve fibers. The pelvic urethra received more large myelinated afferent fibers than the penis. The three divisions of the external anal sphincter muscle had three distinct populations of muscle fibers, based on size distribution. The homologous bulbospongiosus and constrictor vulvae muscles had different populations of muscle fibers.

    Notes: Muscles of the perineal region were dissected in 20 cats. Levator ani muscle was composed of two parts: iliocaudalis and puboischiocaudalis; both parts inserted entirely on caudal vertebrae, as did the coccygeus muscle. A well developed band of smooth muscle, the pars analis of retractor penis (clitoridis), inserted on the anal canal to retract the anus. The external anal sphincter had pars caudalis and pars cranialis divisions, the latter covered paired anal sacs. In addition, a distinct sphincter encircled each anal sac duct. In the male, levator scroti muscle originated from external anal sphincter. There was no continuity between external anal sphincter and bulbospongiosus muscles. Cremaster muscles were absent in the cat. In the female, pars cranialis of external anal sphincter gave origin to the constrictor vestibuli muscle, and pars caudalis to constrictor vulvae muscle. Bulboglandularis muscles were present in both sexes. Urethralis, ischiourethralis, and ischiocavernosus muscles in the cat were similar to other quadripeds.

    A study of the effect of pregnancy on muscle fibers of the rectus abdominis muscle of the ratSupported by General Research Support Grant RR05374 General Research Support Branch, Division of Research Facilities and Resources, NIH. (1979)

    Notes: Samples of the rectus abdominis muscle were taken from Sprague-Dawley rats at 0, 3, 6, 9, 12, 15, 18, and 21 days of pregnancy, and at 1, 3, 6, 9, 12, and 15 days of postpartum. Sections were incubated for actomyosin adenosine triphosphatase activity following preincubation at a basic pH. Muscle fibers within a unit area of each sample were identified as to fiber type according to their enzyme activity, and the population of each type counted. The proportion of each fiber type was calculated and the diameter of 24 fibers of each type measured. No changes were noted in the muscle fiber proportions through the course of the experiment. Differential changes in muscle fiber diameters were noted in each of the three muscle fiber types. Slow oxidative fibers underwent an increase in diameter through the last half of pregnancy. The diameter was further increased as stretch of the muscle was released after birth, and did not decrease in the postpartum period. Fast glycolytic fibers decreased in diameter during the last half of pregnancy, but returned to the prepregnancy diameter in the first postpartum day. The diameter of the fast oxidative glycolytic fibers remained unchanged through the course of pregnancy and in the postpartum period.
