This study provides some comprehensive osteometric and morphologic descriptions of the skull region of the Markhoz goat. Totally, 17 osteometric parameters of eight skulls of Markhoz goat were measured and expressed as mean ± SD. A skull length of 18.67 ± 0.66, a cranial length of 11.1 ± 0.38, a facial length of 10.23 ± 0.76, a skull index of 47.77 ± 1.96, a cranial index of 54.04 ± 2.29, a facial index of 100.77 ± 6.85 and a foramen magnum index of 89.32 ± 14.1 were recorded. Morphologically frontal bone did not constitute the caudal extent of frontal surface; rather it was formed by the parietal bone. There were two supraorbital foramina in both sides. The prominent facial tuberosity lies dorsally to the 3rd cheek tooth. The infraorbital foramen was single on either side which was located directly dorsally to the junction of the first and second upper premolar. The orbits were round and complete and located on a frontolateral oblique plane. The basilar part of the occipital bone was surrounded by two pairs of muscular tubercles with similar size. The temporal line was continuous of the temporal crest and ran over the parietal bone. In conclusion, the morphologic and osteometric data of Markhoz goat are comparable to other ruminants.
本研究提供了马尔霍兹山羊颅骨区域的一些全面的骨测量和形态学描述。总共测量了8个马尔霍兹山羊颅骨的17个骨测量参数，并表示为平均值±标准差。记录到头骨长度为18.67±0.66、颅长为11.1±0.38、面长为10.23±0.76、头骨指数为47.77±1.96、颅指数为54.04±2.29、面指数为100.77±6.85以及枕大孔指数为89.32±14.1。形态学上，额骨并不构成额面的尾端范围；相反，它是由顶骨形成的。两侧均有两个眶上孔。突出的面部结节位于第三颗颊齿的背侧。眶下孔在两侧均为单个，直接位于第一和第二上前磨牙交界处的背侧。眼眶呈圆形且完整，位于前外侧斜面上。枕骨的基底部分被两对大小相似的肌肉结节包围。颞线与颞嵴相连，越过顶骨。总之，马尔霍兹山羊的形态学和骨测量数据与其他反刍动物相当。
