The Cell Theory states that: 1) All organisms are made up of one or more cells and the products of those cells. 2) All cells carry out life activities (require energy, grow, have a limited size). 3) New cells arise only from other living cells by the process of cell division.tructure-a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like. Function-the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out).
The anatomy and structure of the five sense organs of the human body: vision, hearing, smell, taste, and touch.
The twelve cranial nerves serve the head and neck. The vagus nerve (cranial nerve X) has autonomic functions in the thoracic and superior abdominal cavities. The special senses are served through the cranial nerves, as well as the general senses of the head and neck.The movement of the eyes, face, tongue, throat, and neck are all under the control of cranial nerves.he olfactory, optic, and vestibulocochlear nerves (cranial nerves I, II, and VIII) are dedicated to four of the special senses: smell, vision, equilibrium, and hearing, respectively. Taste sensation is relayed to the brain stem through fibers of the facial and glossopharyngeal nerves.
