Document Summary
Components and location: gross anatomy large visible structures like surface, clinical, microscopic anatomy examines cells and molecules. Function of body: cell physiology processes within and between cells, organ physiology function of specific organs, systemic physiology function of an organ system, pathologic physiology effects of disease. Homeostatic regulation: changes in body to stay at homeostasis. Cells communicate to each over via: hormones, neurotransmitters. Nerve cells via chemical messengers: paracrine agents. Stimulus receptor control center effector response. Change in environment sensitive to this change processes info and sends command responds to oppose stimulus. Effector opposes stimulus (aka change apposes the stimulus) Ex: thermoregulation, maintenance of blood glucose level, blood pressure. A response that exaggerates or enhances the change. Dangerous or stressful process must be completed quickly. Anatomical position: standard anatomical reference for the human body, hands at side, palms outwards and forwards, feet together.
