It then turns inward on the ventral surface of the lateral pterygoid muscle and the mandibular nerve, passes between that muscle and the tensor palati, and runs forward to enter the alar foramen. This part gives off the following branches: 1. The inferior alveolar artery (A. alveolaris mandibulse s. inferior)^ passes downward and forward with the homonymous vein and nerve, being at first between.
