Teas 7 - Anatomy And Physiology Already Passed

Mitosis {Ans: Part of eukaryotic cell division during which the cell nucleus divides. All cells in the body (somatic cells), except those that give rise to the eggs and sperm (gametes), reproduce this way.}Dorsal Cavity {Ans: The smaller of the two main cavities is called the dorsal cavity. As its name implies, it contains organs lying more posterior in the body. The dorsal cavity, again, can be divided into two portions. The upper portion, or the cranial cavity, houses the brain, and the lower portion, or vertebral canal houses the spinal cord.}Cell Structure {Ans: A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm are organelles.}Meninges {Ans: The three protective membranes that surround the brain and spinal cord}Superior/Cranial {Ans: Toward the head end of the body; Upper}Cytoplasm {Ans: The gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell. Materials move by diffusion, a physical process that can work only
