双峰驼的下颌神经

运用大体解剖学方法对5例骆驼头左右两侧进行详细的解剖,以研究双峰驼的下颌神经。双峰驼的下颌神经的主要分支有颞深神经、咬肌神经、颊神经、舌神经、下齿槽神经、下颌舌骨肌神经、翼内侧肌神经、翼外侧肌神经和耳颞神经。颊神经在其起始部有较粗的交通支与上颌神经和腭大神经相连;在颊后部外侧面分为7～8条小支,形成颊神经丛。双峰驼有1～2个颏副孔,下齿槽神经在下颌管内分出1～2条颏副神经,穿经颏副孔,分布于颊及下唇。

The Mandibular Nerve of the Two-humped Camel (Camelus bactrianus)

Five (?)wo-humped camel heads were dissected extensively to study their mandibular nerves. The mandibular nerve of the camel gives off the deep temporal, masseteric, buccal, lingual, inferior alveolar, mylohyoid, medial peterygoid, lateral peterygoid and auriculotemporal nerve. The buccal nerve gives off a branch to the medial peterygoid muscle and is called the anterior nerve to medial peterygoid muscle. At the beginning part of the buccal nerve it is connected with the maxillary, greater palatine nerve and dorsal buccal branch of the facial nerve by means of communicative branches. On the lateral aspect of the bucca the buccal nerve divides into several twings to form the buccal plexus. The accessory mental foramen exists in the camel; two large accessory mental nerves arise from the inferior alveolar nerve,passes through the accessory mental foramen and distributes to the bucca and the lower lip.
