The buccinator muscle is innervated by Facial nerve.

Explanation:

Buccinator muscle is a thin quadrilateral facial muscle that is between the interval of the mandible and maxillae at the side of the face. It form the anterior part of the cheek to the teeth and help in holding the cheek to the teeth. It also help in chewing. It is innervated by the buccal branch of the facial nerve.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
