Cocaine can be detected in the system anywhere from 12 hours to 4 days after use. The length of time cocaine stays in your system depends on the dosage amount ingested, the route of administration and frequency of use.

Other muscles involved in chewing are the obicularis oris and the zygomaticus. Both are lip muscles. The buccinator holds food in contact with the teeth. All three are innervated by the facial nerve (CN.
Other large chewing muscles are attached on the side surfaces of the rami. The mandible (lower jawbone) consists of a horizontal horseshoe-like body with a flat ramus projecting upward at each end. The rami are divided into two processes: the mandibular condyle and a front coronoid process. The mandibular condyles unite with the mandibular tissues of the temporal bones, while the coronoid processes serve as attachments for muscles used in chewing.
