2、鼻骨
鼻骨位于鼻背的成对的小骨，长方形，上厚下薄，支撑着鼻背。鼻骨上接额骨，下接鼻软骨，外侧接上颌骨，内侧接对侧鼻骨。鼻骨成对，位于额骨的下方中线的两侧，组成鼻背。

3、颧骨
颧骨是面颅骨之一，位于面中部前面，眼眶的外下方，菱形，形成面颊部的骨性突起。颧骨共有四个突起，分别是：额蝶突，颌突，颞突和眶突。颧骨的颞突向后接颞骨的颧突，构成颧弓。

4、颞骨
颞骨是成对的脑颅骨之一。属于颅骨中的脑颅骨，共两块，左右各一。位于头颅两侧，并延至颅底，参与构成颅底和颅腔的侧部，形状不规则。以外耳门为中心可分为颞鳞、鼓部和岩部3部分。颞骨与大脑及颅内的许多重要神经血管关系密切。

5、下颌骨
下颌骨位于面下部，呈弓形，围成口腔的前壁和侧壁，是面部唯一能活动的骨骼。
