Anatomy Lecture pt.1
Chapter 1
| 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 |
