Morphological and stereotaxic studies of Iranian native goat's brain

This study was conducted to find out the best outside points of skull to reach different areas of brain that are essential for neuroendocrinological studies. In this research 30 heads of Iranian native male goats aged between 2-3-year-old were collected from Shahrekord abattoir. After collecting whole heads, they were fixed in 10% formalin and then many holes were made on the dorsal surface of skull followed by median and transverse sectioning of the heads. Morphological characteristics of brain and distances from the bones of skull to different structures of brain were measured using caliper device and needle and the best points were determined. By this method the best points to reach the hypophysis and lateral ventricle with 90° angle are in distances of 45.2 ± 2.23 mm and 20.92 ± 1.02 mm at bregma point.
