{"title":"Clinical anatomy of the m. flexor carpi radialis tendon sheath.","authors":"H M Schmidt","doi":"","DOIUrl":"","url":null,"abstract":"At the transitional zone from the forearm to the hand the insertion tendon of the m.flexor carpi radialis (FCR) glides on a fibrous and fatty cushion, which is connected dorsally with the joint capsule of the radiocarpal articulation. The tendon distally crosses the palmar side of the scaphoid tubercle and enters the dorsally curved rim of the trapezoid tubercle. At the level of the wrist joint the narrow tendon sheath begins, which extends to the insertion at the metacarpus. Immediately after entering the gliding tunnel the tendon branches off radially as a rule with an accessory fibre strand 8 mm in width to the scaphoid, trapezium and the joint capsule between these two bones. The insertion tendon regularly is attached to the palmar and radial surfaces of the second and third metacarpal bones. The wall of the osteofibrous gliding tunnel can be prominent following trauma, inflammation or arthrosis deformans in the trapezio-scaphoideal joint and may irritate the tendon (tendovaginosis stenosans). Against resistance forces pain will occur in the wrist joint during palmar flexion. The typical point of tenderness is situated at the entering of the tendon in the thenar region. Operative decompression will be effective by opening the radial wall of the tendon sheath from the carpal tunnel.","PeriodicalId":75392,"journal":{"name":"Acta morphologica Neerlando-Scandinavica","volume":"25 1","pages":"17-28"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13596091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The distribution of motoneurons supplying hind limb muscles in the clawed toad, Xenopus laevis.","authors":"J B Hulshof, R de Boer-van Huizen, H J ten Donkelaar","doi":"","DOIUrl":"","url":null,"abstract":"The distribution of motoneurons in the lumbar spinal cord (spinal segments 8-10) of the clawed toad, Xenopus laevis, was studied with the horseradish peroxidase technique. In a total of 13 different hind limb muscles this tracer was applied in a slow-release gel. Motoneurons innervating a particular hind limb muscle were clustered in longitudinally arranged motor pools. Motor pools of different muscles did show considerable overlap both in the rostrocaudal and transverse plane. But, the various motor pools clearly show a somatotopic organization of motoneurons even in such a condensed lumbar spinal cord as in Xenopus laevis. Motoneurons innervating more distally positioned muscles are generally found in more caudal segments, while proximal muscles (with the exception of the m. adductor magnus) are supplied by motoneurons more or less throughout the lumbar enlargement. Flexor muscles usually are innervated by motoneurons situated ventrolaterally in the ventral horn, extensor muscles by dorsomedially found motoneurons. This pattern is particularly apparent for proximal (thigh) muscles, less so for more distal (shank and foot) muscles. The present data are in keeping with those obtained with the retrograde cell degeneration technique in ranid frogs and are consistent with observations in other tetrapods, although a more clear separation of motor pools is evident in \"higher\" vertebrates such as birds and mammals.","PeriodicalId":75392,"journal":{"name":"Acta morphologica Neerlando-Scandinavica","volume":"25 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14563896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A microscopical study.","authors":"F M Griffioen, J H Smit-Vis, P Brugman, I J de Groot, W G Sinnige","doi":"","DOIUrl":"","url":null,"abstract":"In order to study the effects of surgical procedures on the regeneration process in cleft palate, an artificial cleft was made in 4-weeks old female New Zealand rabbits. The 47 animals were divided into 5 groups: group 1: controls, group 2: cleft made in the bony palate, using a dental burr (phi 3 mm), group 3: cleft as in group 2, oral mucosa stitched, group 4: cleft made without perforating the nasal mucosa; oral mucosa stitched (\"Veau\"), group 5: cleft made as in group 4; before stitching the oral mucosa pieces of autologous rib bone were introduced into the cleft (\"Schuchardt\"). At the ages of 4, 5, 6, 8, 12, 18 and 24 weeks, one or two animals per group were sacrificed. The palatal region was microscopically studied using 10 mu paraffin sections stained according to Herovici. It was found that it is difficult to make a reproducible cleft on the histological level. A large interindividual variation in local damage due to the surgical procedure was observed; this might contribute to the variation in growth results of the facial skeleton reported in literature. Signs of excessive bone resorption were found. The presence of bone in places where sutural tissue should be present, observed in some growing animals, will contribute to reduction of palatal width, medial collapse of the palate and asymmetry of the facial skeleton. There appeared to be no striking differences between the three methods of repair, used in group 3, 4 and 5 respectively.","PeriodicalId":75392,"journal":{"name":"Acta morphologica Neerlando-Scandinavica","volume":"25 4","pages":"215-25"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14629627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An anthropometric approach to the study of evolution. 研究进化的人体测量学方法。

{"title":"An anthropometric approach to the study of evolution.","authors":"G N van Vark","doi":"","DOIUrl":"","url":null,"abstract":"The study of human evolution has always been a major issue in physical anthropology. Since computers became available this study became a new dimension in that it became feasible to apply advanced mathematical multivariate methods which make use of morphometric data. However, looking back on what has been achieved so far with these methods, it must be admitted that the results obtained are often unsatisfactory. This has led to a certain lack of acceptance of these methods. In the present paper it is argued that very useful results may be obtained by applying more sophisticated multivariate methods which are specifically designed for the anthropological problems at issue. Three examples are given. The first deals with the controversy between \"Creationism\" on the one hand and \"Evolutionism\" on the other. Our results strongly support the Evolutionists' point of view. The second example deals with the reconstruction of human phylogeny. An investigation is discussed which has led to a startling new hypothesis concerning the evolution of man. The last example concerns a preliminary investigation of trends in human sexual dimorphism. The results obtained so far seem to support the opinion expressed by other workers that tendencies exist in our modern society which lead to changes in the present dimorphism.","PeriodicalId":75392,"journal":{"name":"Acta morphologica Neerlando-Scandinavica","volume":"25 2","pages":"107-16"},"PeriodicalIF":0.0,"publicationDate":"1987-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14263307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
