Summary Seventy-one Caucasian orbits (36 right, 35 left) were studied by dissection. The diameter of the ophthalmic a. (2 mm from the origin) was 1.54 ± 0.04 mm (male) and 1.31 ± 0.05 mm (female). In individual cases, there were no significant differences in vessel diameter between the right and left sides but, differences in vessel diameter between males and females were more commonly observed in the arteries which leave the orbit (extraorbital group), the individual vessels having a larger diameter in males. The incidence of the ophthalmic a. passing in the orbit medially under the optic n. was 18.6%. The lacrimal a. was observed to arise from the ophthalmic a. in only 82.5% of the cases examined, 15.9% of the cases showed the origin to be at the anastomotic branch of the middle meningealThis article is dedicated to Pr Dr Hoepke on occasion of his 100th birthday 相似文献

Summary Unit activites of secondary vestibular neurons that selectively responded to stimulation of the anterior semicircular canal nerve (ACN) were recorded extracellularly in the anesthetized cat. Axonal pathways and projections in the spinal cord of the ACN-activated neurons were examined by recording their antidromic responses to stimulation of the lateral and medial vestibulospinal tracts (LVST and MVST), and the bilateral neck extensor motoneuron pools in the C1segment (C1dorsal rami [DR] motoneuron pools). In order to determine whether the neurons had ascending axon collaterals to the extraocular motoneurons, the contralateral (c-) inferior oblique (IO) motoneuron pool was also stimulated. Twenty-seven neurons sent their axons to the ipsilateral (i-) C1DR motoneuron pool via the LVST without any projection to the extraocular motoneuron pool. All the cells except one were located in the ventral part of the lateral vestibular nucleus. This pathway produced monosynaptic EPSPs with short time-to-peak and short half-width in C1DR motoneurons (16/16 motoneurons). Eight neurons sent axons to the i-C1DR motoneuron pool via the MVST without any to the extraocular motoneuron pool. Cell somata were located in the descending nucleus or in the ventral part of the lateral nucleus. These neurons did not produce postsynaptic potentials (PSPs) in any C1DR motoneurons. All thirty-five neurons sending axons to the c-C1DR motoneuron pool have ascending axon collaterals to the c-IO motoneuron pool. 相似文献

舌下神经管及其毗邻结构的显微解剖和临床意义 总被引:2,自引:0,他引:2
目的:研究舌下神经管及其毗邻结构的显微解剖,为舌下神经管疾病的影像学诊断和手术入路的选择提供形态学数据。方法:肉眼和手术显微镜下观测30例(60侧)成人头颅干骨标本的舌下神经管及其毗邻结构。结果:舌下神经管位于枕骨髁的前上方,为一对卵圆形或圆形孔道,内口至外口的长度(8.51±0.91)mm。舌下神经管内口呈双管者5侧(8%);内口后缘与枕骨髁后缘的距离(10.07±0.75)mm,外口后缘至枕骨髁后缘(14.22±1.18)mm。左、右侧枕骨髁的前后径分别为(23.10±1.57)mm、(22.38±2.28)mm。结论:熟悉舌下神经管及其毗邻结构的解剖有利于相关疾病的影像诊断和手术入路的选择。 相似文献

Summary This paper begins with a review of the embryology of the inguinal region. The authors then point out the special morphological and topographical features of the inguinal canal in male children. These observations were based on the study of 50 inguinal canals from male children. From the anatomical observations described in this study guidelines are proposed for the surgical approach and dissection of the spermatic cord used in the treatment of congenital hernias or abnormal descent of the testis.
Bases anatomiques de la chirurgie inguinale de l'enfant
Résumé Après une étude embryologique de la région inguinale, les auteurs décrivent les particularités morphologiques et topographiques du canal inguinal en croissance de l'enfant de sexe masculin, se basant sur l'étude de 50 cas. De ces notions anatomiques découlent des règles chirurgicales sur la voie d'abord et la dissection du cordon spermatique lors des cures de hernies congénitales ou d'anomalies de migration testiculaire.相似文献

The present work was a longitudinal study on Schistosoma mansoni infection in occupationally hyperexposed canal cleaners in the Sudan and the influence of therapy on the parasitological and humoral immune parameters. Chronically infected canal cleaners (n = 28) were more resistant to reinfection (Fisher's exact test, P < 0.05) than newly recruited canal cleaners (n = 17). Chronically infected canal cleaners had a significantly higher degree of Symmers' fibrosis (χ2 = 19.1, P < 0.0001), significantly larger portal vein diameter (P < 0.05) and enlarged spleen (χ2 = 4.2, P < 0.05) than recently infected, newly recruited canal cleaners. ELISA was used to detect IgG, IgA and IgM in response to whole worm homogenate (WWH) and cercarial homogenate (CH). Chronically infected canal cleaners had significantly higher IgG to WWH antigen than newly recruited canal cleaners and normally exposed individuals (P < 0.05), while both chronically infected and newly recruited canal cleaners had higher IgG levels to CH antigen than normally exposed individuals (P < 0.05). The newly recruited canal cleaners had a significantly higher IgM level to CH antigen than chronically infected canal cleaners (P < 0.05). The IgG level to WWH antigen increased significantly after treatment in newly recruited canal cleaners and normally exposed individuals (P < 0.05). The IgA level to CH antigen increased significantly after treatment in the chronically infected group (P < 0.05). Comparison of the serological parameters between the different study groups with regards to infection and treatment is discussed. 相似文献
