Question | Answer |
What are the 3 divisions of Anatomy? | Gross or Macroscopic Microscopic Developmental |
Gross Anatomy | Regional Systemic Surface |
Microscopic | Cytology-study of cells Histology- study of tissues |
Developmental | Traces structural changes throughout life |
Embrology | Study of developmental changes of the body before birth. |
Specialized Branches of Anatomy | Pathological Radiographic Molecular |
Renal | Kidney function |
Neurophysiology | Workings of the nervous system |
Cardiovascular | Operation of the heart |
Principle of Complementarity | Know that all systems are always related to eahother |
Levels of Structural Organization | -Chemical -Cellular -Tissue -Organ -Organ System -Organismal |
Organ System Interrelationship | Know that no organ works by itself |
Necessary Life Functions | -Maintaining Boundaries -Movement -Responsiveness -Digestion -Metabolism -Excretion -Reproduction -Growth |
Survival Needs | Nutrients Oxygen Water Maintaing normal body temperature Atmospheric Pressure |
Homeostasis | Homeostasis is the ability to maintain a relatively stable internal environment in an ever changing outside world. |
Receptor | monitors the environment and responds to change |
Control Center | Determines the set point at which the variable is maintained |
Effector | provides the means to respond to the stimulus |
Positive Feedback | The output enhances exaggerates the original stimulus. (when high becomes higher)(blood clot) |
Homeostatic Imbalance | Occurs when you have a disease |
Anatomical Position | Body erect,feet slightly apart, palms facing forwards, thumbs point away from the body |
Dorsal Cavity | Cranial (skull & brain) Vertebral (spinal cord) |
Ventral Cavity | Thoracic Cavity Abdominpelvic |
Pleural (subdivision of thoracic) | each houses a lung |
Mediastinum(subdivision of thoracic) | contains the pericardial cavity surrounds the reaming thoracic organs |
Pericardial Cavity(subdivision of thoracic) | encases the heart |
Amdoninpelvic | Abdominal cavity- contains the stomach,intestines,spleen,liver,and other organs Pelvic Cavity- lies within the pelvis and contain the bladder,reproductive organs,and rectum |
Parietal Serosa | lines internal body |
Visceral Serosa | covers internal organs |
Serous fluid | separates the serosae |
