Mouth site where mechanic and chemical breakdown occur. Teeth 32 permanent teeth top row are duplicated by the same named teeth in the bottom row. 2 x ( 2 central incisors, 2 lateral incisors, 2 canine, 2 premolar and 6 molar [3rd are wisdom classified as vestigial]) Salivary glands the body has three pairs of salivary glands (saliva breaks down carbohydrates: parotid gland located outside the mouth, similar to putty pushed into the cavity just in front of the ear. Because it is superficial it is protected by capsule: duct goes forward across the masseter muscle, pierces cheek muscle (2nd-3rd molar) and empties into mouth, submandibular gland inside surface of the mandible bone.
