looks like a bean with folds cristae inside rough endoplasmic reticulum surrounds the nucleus has condensed small dense bodies and ribosomes on the outside Golgi apparatus short smooth membranous sacs stacked upon each other and small vesicles centrioles comes in pairs has 9 triplets of microtubes ribosomes small particles found either clustered free in the cytoplasm or attached to the endoplasmic reticulum cilia cilium motile mobile eye lash like processes which come off of the cell membrane microvilli much smaller non motile finger like processes all same size and shape and often evenly over the cells apical surface prophase phase of cell division that appear as threads With in the nucleus clumped threads metaphase chromosomes line up in center of cell nuclear envelope disassembles anaphase pulled apart chromosomes look like strands moving opposite of each other telophase chromosomes are clumped together cell appears to be pulled apart into two frontal bone forehead anterior

of the maxilla that articulates With the palatine bone alveolar process ridge of bone that contains sockets for our teeth body centrum of vertabra each vertabrae has a rounded body that connects With a thin arch of bone called the vertebral arch vertebral foramen a hole space that is surrounded by the body and vertebral arch they form the vertebral canal Where the spinal cord passes through transverse processes located on either side of the vertebral arch spinous process located on the posterior part of the vertebral arch pointing downwards superior articular processes 2 arises from the arch has a surface for articulation With the adjacent vertebra inferior articular processes 2 arises from the arch has surface for artic with adjacent vertabra cervical vertebra region top 7 vertebrae
