    Notes: Abstract Chronic pain on the ventral surface of the scrotum and the proximal ventro-medial surface of the thigh especially in athletes has been diagnosed in various ways; recently, in Europe the concept of “sports hernia” has been advocated. However, since few reports discuss the detailed course of the nerves in association with the pain, we examined the cutaneous branches in the inguinal region in 54 halves of 27 adult male cadavers. From our results, in addition to the cutaneous branches from the ilioinguinal n. (in 49 of 54: 90.7%), cutaneous branches originating from the genital branches of the genitofemoral nerve were found in the inguinal region in 19 of 54 halves (35.2%). In 7 cases (in 7 of 54: 13.0%) the genital branch and the ilioinguinal nerve united in the inguinal canal. In 6 cases the genital branch pierced the inguinal lig. to enter the inguinal canal, and in three cases the genital branch pierced the border between the ligament and the aponeurosis of the obliquus externus m. to be distributed to the inguinal region. Therefore, the courses of the genital branches vary considerably, and may have a very important role in chronic groin pain produced by groin hernia. In addition, entrapment by the ligament may be a reasonable candidate for the cause of chronic groin pain.

    Description / Table of Contents: Résumé La douleur chronique de la face ventrale du scrotum et de la face ventro-médiale proximale de la cuisse, en particulier chez les athlètes, a été interprétée de différentes manières ; le concept de “hernie du sport” a été récemment évoqué en Europe. Cependant, depuis que quelques rapports ont décrit le trajet détaillé des nerfs en association avec la douleur, nous avons examiné les branches cutanées de la région inguinale chez 27 cadavres mâles adultes (54 dissections). D'après nos résultats, dans la région inguinale, en plus des branches cutanées provenant du nerf ilio-inguinal (dans 49 des 54 cas ; 90,7 %) des branches cutanées provenant des branches génitales du nerf génito-fémoral ont été trouvées dans 19 des 54 dissections (35,2 %). Dans sept cas (7 des 54 cas, soit 13 %) la branche génitale et le nerf ilio-inguinal étaient unis ensemble dans le canal inguinal. Dans six cas, la branche génitale traversait le ligament inguinal pour entrer dans le canal inguinal, et dans trois cas la branche génitale traversait la frontière entre le ligament et l'aponévrose du muscle oblique externe pour se distribuer à la région inguinale. Ainsi, les trajets des branches génitales sont extrêmement variables, et peuvent avoir un rôle très important dans la douleur chronique de l'aine, attribuée habituellement à la hernie de l'aine. De plus, la contrainte mécanique liée au ligament peut être raisonnablement à l'origine de la douleur chronique de l'aine.

    Morphology of the teeth of adult caudata and apoda: Fine structure and chemistry of enamel (1992)

    Notes: Representative functional teeth from Cryptobranchus alleghaniensis (Cryptobranchidae), Amphiuma means (Amphiumidae), Dicamptodon ensatus (Dicamptodontidae), Necturus maculosus (Proteidae), and Dermophis sp. (Costa Rica) (Caeciliidae) were prepared for transmission electron microscope and electron microprobe analysis of the trace elements of the enamel layer. The enamel layer of these species is very thin and the arrangement of enamel crystals variable. In particular, the outer part of the enamel layer in which hydroxyapatite elements (Ca, P) and trace elements (e.g., F, Fe, Mg) are concentrated, is most heavily mineralized. The concentrations and alignment of crystals in the outer and inner parts of the enamel layer differ among these species.The presence of collagen fibers in the inner part of the enamel layer of Cryptobranchus and Dermophis indicates that it is enameloid rather than true enamel. The presence of trace elements may be related to the pattern of mineralization of enamel or enameloid, as suggested for tetra-odontiform fishes by Suga et al. (J. Dent. Res. 68:1115-1123, 1989). © 1992 Wiley-Liss, Inc.

    Histochemical study of jaw muscle fibers in the American alligator (Alligator mississippiensis) (1992)
    New York, NY : Wiley-Blackwell
    Journal of Morphology 211 (1992), S. 187-199 
    Details
    ISSN: 0362-2525

    Notes: Seven jaw muscles of the American alligator have been analyzed for histochemical characteristics of their fiber types: Musculus depressor mandibulae (MDM), M. pseudotemporalis (MP), M. adductor mandibulae posterior (MAMP), M. adductor mandibulae externus (MAME, profound and superficial portions), M. intramandibularis (MI), M. pterygoideus anterior (MPta), and M. pterygoideus posterior (MPtp). Classification of muscle fibers in previous studies has been based on (1) the staining properties of myosin ATPase after alkaline and acid preincubations and (2) the staining reactions for SDH, α-GPDH, PAS, and myosin ATPase after alkaline preincubations. In this study fiber types in one group of muscles (MP, MAMP, profound portion of MAME and MI) are classified (1) as type I, IIa, or IIb fibers, according to the system of Brooke and Kaiser (Arch. Neurol. 23:369-379, '70) or (2) as fast twitch glycolytic (FG), fast oxidative glycolytic (FOG), slow oxidative (SO), and tonic (few in number) fibers, according to the system of Putnam et al. (J. Exp. Zool. 214:303-309, '80). A second group of muscles (MDM, MAME superficial portion, MPta, and MPtp) reacted differently in similar histochemical tests and are classified, respectively, as (1) types 1, 2, 3 or (2) types A, B, C. We have distinguished the fiber types as red, intermediate, white, and tonic in analyses on muscle sections. The highest percentage of red and intermediate fibers is found in the MI. All three fiber types are approximately equal in superficial and medial portions of the MDM and the MPtp. Three muscles (MP, MAMP, and MAME) have the highest white fiber composition. These results indicate a correlation between the histochemical profiles of individual muscles and their functions during masticatory movements.
