Asymmetry of the face and facial expressions in relation to handedness
Hřebcová, Eliška ; Velemínská, Jana (advisor) ; Kožejová Jaklová, Lenka (referee)
Facial asymmetry is developed in every human and has an impact on everyone's life. Research of facial asymmetry is important not only in plastic surgery, aesthetic medicine and orthodontics, but also in forensic sciences, bioarchaeology and sociocultural anthropology. It can be influenced by various factors including the lateralization of cerebral hemispheres for cognitive and motor functions. According to the literature, handedness in humans is one of the most important forms of laterality which is probably related to facial asymmetry. The observed asymmetries differ not only between left-handers and right-handers, but also between men and women. Emotional expressions are also expressed asymmetrically on the face. Differences between positive and negative emotions as well as spontaneous and voluntarily expressions were observed. Different forms of laterality of motoric and cognitive cerebral functions are related to each other and their impact on facial asymmetry is therefore very complex.

Pelvic asymmetry in relation to the human reproduction
Kodytková, Aneta ; Brůžek, Jaroslav (advisor) ; Bigoni, Lucie (referee)
This diploma thesis deals primarily with the existence of the asymmetry of the bony pelvis and the sexual dimorphism of the asymmetry of the pelvic canal, which is caused by different reproductive functions of each of the sexes. Furthermore, the correlation or linear dependence of the external pelvic and pelvic canal dimensions was investigated. The study uses 3D pelvic models created in Avizo 7.1 from CT images of the recent French population. The material consists of 74 probands, of which 36 are males and 38 are females. The models were digitalized using Viewbox 4 software, in which 29 landmarks were applied to each pelvic model. These correspond to 24 dimensions divided into three groups: the size of the non-canal pelvis, the dimensions of the pelvic canal and the dimensions for calculating the correlation between the non-canal pelvis and the pelvic canal. The degree of asymmetry was evaluated using the formulas for the calculation of directorial (DA) and absolute (AA) asymmetry. Student's paired t-test was used for statistical analysis of asymmetry to determine asymmetry in previous studies. Gender differences were determined by the Mann-Whitney U test. At the same time, an analysis using the mixed model ANOVA was also performed, which in addition incorporates an intraobservation measurement...

Asymmetry of the human face
Korbelová, Tereza ; Velemínská, Jana (advisor) ; Hoffmannová, Eva (referee)
Facial asymmetry affects human life, especially in relationships with other people. Individuals with pathological asymmetries may have difficulty with integration into the collective, whether in childhood at school or later in adulthood at work. Presence and size of asymmetry reflects the potential quality of an individual's genes. Scientific research focused on measurement and evaluation of facial asymmetry provides valuable knowledge for various branches of medicine mainly for plastic surgery and orthodoncy, but also for forensic science, where it is used for personal identification. Asymmetries develop in the prenatal period and then they envolve and grow by the influence of external and internal factors during lifetime.
