Capable of locomotion (moving from one place to another)! Physiological sub disciplines: biological level of organization : cell and molecular physiology genetics, metabolism, organelles, systems physiology functions of organs, organismal physiology whole animal, ecological physiological animal and its environment, integrative physiology multiple levels of organization! The most basic unit of physiology is the atom > atoms make molecules > molecules make cells >cells make tissues > tissues make organs > organs together make organ systems ! Four major cell types : neurons correspond with nerve tissues, muscle cells three types: skeletal, smooth and cardiac muscle cells, epithelial cells correspond with epithelial tissue, connective tissue cells blood cells, bone cells and broblasts (in skin and other tissues)! Organ systems: the nervous system consists of the brain and spinal cord (central nervous system) and peripheral nerves (peripheral nervous system)! Provide communication between cells of the body through electrical signals and the release of neurotransmitters into small gaps between certain cells!
