ABSTRACT
The paper deals with a part of anatomical research in aspect of clinical evaluation of lowering mandible muscles attachments (mylohyoid m, digastric m, geniohyoid m.) and genioglossus muscle. The research was conducted on 183 adult males and 117 females crania. The variance analysis of Tukey's revealed, that crania traits established on the basis of statistical parameters of breadth-length index, and visceral cranium height-breadth index, are significant. In order to establish statistical characteristics of examined traits, including into research sexual dimorphism and bilateral differences is also very important.

The aim of the paper is computer transformation of the transversal research results of male (214) and female (178) genital internal organs (examined in 4 months's intervals) in a way enabling longitudinal evaluation.

The number of arteries providing blood supply for the thyroid gland as well as the origin of the superior thyroid and inferior thyroid arteries were examined in 132 fetuses from single pregnancies and in 144 fetuses from twin pregnancies, aging 4 to 9 months. Most frequently (81% cases) four thyroid arteries were observed. Five thyroid arteries were noted in 14.4% cases. Sources of additional thyroid arteries were described.

In 80 human fetuses of both sexes, aged 4 to 7 months the spatiality of the intervertebral foramina and the area of the cross-section of the spinal nerves at the level of C4-T2 of the vertebral column were investigated. It was found that the narrowness of the intervertebral foramen is not related to the sex of fetus. The most probable places for such narrowness are intervertebral foramina C4-C5 and T1-T2 on the right side and C7-T1 on the left side.

The authors disposed of numerous cases of fetuses normally aborted during the long period of time therefore the studies of time dependent variability of some somatotropic features in relation to the degree of development were decided. The studies on the fetal material should be always performed with great care as many errors could be introduced. Some of them are related to not enough accurate determination of the fetal age and the variability of the causes of abortion. These would result the inconsistency of stages of fetal development among the material used for the study. Therefore the research was performed using only the fetuses with accurate estimated calendar age and of similar environmental conditions for development. The causes of the abortion were related only to external factors but not to the course of pregnancy. For the analysis only the fetuses of 5th and 6th month of fetal age were used. All fetuses were aborted in the years 1965, 1970, 1975, 1980, 1985. The intersexual differences were also taken into consideration and calculated means of the features were related to identical points of the fetal age. The variations in the seating body length (v-tub), the head perimeter, the shoulder width (a-a) and the body weight were analysed in such individualised groups.
