The number of heads possessed by the lateral pterygoid muscle was investigated in the dog. Only a single head was observed which it is suggested may correspond to the lower head in other mammals. It inserted both onto the condyle and into the articular disc. The nerve which innervated this muscle arose directly from the mandibular nerve, separate from the medial pterygoid nerve. Because of this, it should be termed the lateral pterygoid nerve and not the pterygoid nerve.
对犬的翼外肌的头数进行了研究。仅观察到一个头，有人认为它可能相当于其他哺乳动物的下头。它附着于髁突并插入关节盘。支配该肌肉的神经直接发自下颌神经，与翼内肌神经分开。因此，它应被称为翼外肌神经而非翼肌神经。
