This study was carried out to estimate the relationship between hand length, foot length and stature using multiple linear regression analyses based on a sample of male and female adult Turks residing in Adana. Measurements of hand length, foot length and stature were taken from 155 adult Turks (80 male, 75 female) aged 17-23 years. The participants were students of the Medical Faculty of Cukurova University. A multiple linear regression model was fitted to the observed data. Stature was taken as the response or dependent variable, hand length and foot length were taken as explanatory variables or regressors. All possible (simple and multiple) linear regression models for each of males, females and both genders together were tested for the best model. The multiple linear regression model for both genders together was found to be the best model with the highest values for the coefficients of determination R2 = 0.861 and R2adjusted = 0.859, and multiple correlation coefficient R = 0.928.
This study aimed to determine the mean values of the different morphometric measurements from right and left ears. These measurements were taken from 341 healthy young adults (150 women and 191 men) ages 18 to 25 years using an electronic digital caliper. The results showed the mean values for total ear height, lobular height and width, distances from tragus to antihelix and to helix, and ear projection and width to be, respectively, 59.7 +/- 3 mm, 17.5 +/- 1.4 mm, 18.5 +/- 2.2 mm, 16.6 +/- 1.7 mm, 25.1 +/- 2 mm, 16.6 +/- 2 mm, and 31.3 +/- 2.2 mm for the left ear, and 59.5 +/- 3.1 mm, 17.9 +/- 1.5 mm, 18.9 +/- 2 mm, 16.5 +/- 1.8 mm, 25.2 +/- 1.9 mm, 17 +/- 1.9 mm, and 31.2 +/- 2.2 mm for the right ear in the young women. However, in the young men, these values were, respectively, 63.1 +/- 3.6 mm, 18.3 +/- 1.7 mm, 19.4 +/- 2 mm, 17.2 +/- 1.8 mm, 26.3 +/- 1.9 mm, 17 +/- 2.3 mm, and 33.3 +/- 2.2 mm for the left ear, and 62.9 +/- 3.5 mm, 18.4 +/- 1.7 mm, 19.8 +/- 1.9 mm, 17.2 +/- 1.8 mm, 26.6 +/- 1.9 mm, 17.6 +/- 2.1 mm, and 33.1 +/- 2.1 mm for the right ear.
Four vertical and three horizontal measurements were taken to assess the validity of neoclassical facial canons in 500 (272 female, 228 male) healthy, young adults between the ages of 18 and 25 years from Turkey and to compare them with a different population. The measurements were made by a millimetric compass. The special head height was longer than the special face height in the majority of our group (women/men: 97.8%/91.7%). The three-section facial profile canon was equal in only one male subject (women/men: 0/0.4%). Faces with four equal profile sections were not seen in either of the sexes. The nose length was longer than the ear length in the minority of our population (women/men: 1.5%/1.3%). The intercanthal distance was shorter than the nose width and left eye fissure length in the majority of our subjects (women/men: 50.4%/78.9% and 50.0%/52.2% respectively). The mouth width was greater than 1.5 times the nose width in the majority of this study (women/men: 66.9% vs 49.1%).
The mean values of the widths of genu, body, splenium, and height of the corpus callosum were 13·28±2·10, 7·64±1·07, 12·52±1·35, and 25·47±2·20 mm, respectively in females; whereas, the same measurements were 13·23±2·41, 6·89±2·12, 11·90±1·94, and 25·03±3·38 mm, respectively in males. Moreover, the mean value for the longitudinal dimension of the brain was 150·12±5·04 mm, while that for the corpus callosum was 71·27±3·70 mm in females. Additionally, the mean frontal horn width of the lateral ventricle and the transverse inner diameter of the skull were 34·06±3·05 and 130·76±6·71 mm in females and 34·03±2·78 and 129·96±10·61 mm in males, respectively. Due to these measurements, the values of Evans index which is reflecting the lateral ventricle enlargement were estimated to be 0·25±1·90 and 0·25±1·14 in females and males, respectively. According to our last measurement result, the mean values for the third ventricle width were 3·79±0·85 and 4·12±0·94 mm in females and males, respectively. These findings show that there are differences between the averages of some indices of corpus callosum of our population and the other populations.
