Abstract
The aim of this project is to determine the dimensions of the cranium and the cranial cavity and the intracranial volume in goats, using 64 adults. The dimensions of the cranium and cranial cavity were measured through metric tape and paquimeter, considering the intervals of the largest distances. To determine the intracranial volume, balloons of latex were introduced in the cranial cavity, through the magnum foramen, later on, filled with water that was transferred for graduate test tube. The average and the standard deviation of length, width and height of the cranium, in millimeters, were respectively: 218.01 ± 6.96, 120.17 ± 10.01 and 108.14 ± 4.46. The average and the standard deviation of length, width, height, in millimeters, and of the volume of the cranial cavity, in cubic centimeters, were respectively: 109.31 ± 7.25, 61.36 ± 4.51, 63.85 ± 2.88 and 119.31 ± 12.21. It was observed that, the width of the cranium possesses positive significant correlations with the length (r = 0.6865), with the height (r = 0.5644) and with the intracranial volume (r = 0.5436). They were still established, positive significant correlations among the height of the cranial cavity, with the length (r = 0.5682) and with the intracranial volume (r = 0.5473). Differences were evidenced between males and females, in relation to the dimensions of the cranium and cranial cavity. There wasn’t difference of the intracranial volume in function of the sex of the goats.
