Anatomy Study Guide
Lecture Guide
Term | Definition |
---|---|
Responsiveness | Irritability and adaptability |
Reproduction | Creates new generations of similar organisms |
Metabolism | Chemical operations in the body |
Anatomy | Structure |
Physiology | Function |
Cytology | Studying cells |
Microscopic Anatomy | Requires magnification |
Histology | Studying tissues |
Surface Anatomy | General forms and markings |
Regional Anatomy | Specific regions |
Systemic Anatomy | Organ systems |
Vital Function | Physical and chemical processes responsible for characteristics of life |
Organizational Levels | atoms - molecules- macromolecules - organelles - cells - tissues - organs - organ systems - organism |
Integumentary | Body covering - Maintains temperature control and protects us from environmental hazards |
Skeletal System Function | Support, movement, and protection |
Muscular System Function | Support and movement |
Nervous System Function | Integration and coordination - Short term control |
Endocrine System | Integration and coordination - Long term control * Secrete hormones * Regulate metabolism |
Cardiovascular System Function | Transport blood, oxygen, nutrients, waste, and more |
Lymphatic System Function | Defend against infection and disease |
Lymph | Water and dissolved proteins |
Digestive System Function | Absorption and excretion |
Respiratory System Function | Air delivery |
Urinary System Function | Eliminate waste and excess water |
Reproductive System Function | Production of new organisms |
Homeostasis | Maintain stable internal environment aka - Body's thermostat |
Receptor | Senses a stimulus |
Control Center | Processes information that was presented by stimulus |
Effector | Responds to stimulus |
Negative Feedback Loop | Most feedback loops are this type, response opposes stimulus |
Positive Feedback Loop | Response reinforces stimulus |
Disease | Results from failure of homeostatic regulation |
Anatomical Position | Body standing up, hands at sides, palms facing forward |
Supine | Anatomical position if lying down but facing up |
Prone | Anatomical position if lying down but facing down |
Anterior | Front |
Posterior | Back |
Ventral | Belly side |
Dorsal | Back side |
Cranial, Cephalic | Head |
Caudal | Tail |
Superior | Above |
Inferior | Below |
Medial | Towards midline |
Lateral | Away from midline |
Proximal | Toward trunk |
Distal | Away from trunk |
Superficial | Close to surface |
Deep | Further from surface |
Transverse | Divides body into superior and inferior sections |
Sagittal | Divides body into right and left sections |
Body Cavities | Protect and cushion organs |
Dorsal Cavity | Surround the brain and spinal cord |
Cranial Cavity | Surrounds brain |
Spinal Cavity | Surrounds the spinal cord |
Ventral Cavity | Surround the other visceral organs and make up the viscera - Divided into the (superior) thoracic cavity and the (inferior) abdominopelvic cavity |
Viscera | Gut |
Diaphragm | Muscular wall separating ventral cavity into thoracic and abdominopelvic cavities |
Abdominopelvic Cavity | Surrounds the heart |
Pleural Cavities | Surround lungs |
Pleura | Serous membrane |
Messenteries | Double sheets of peritoneum for support and stability |
Radiological Methods | Used to give detailed info about internal systems |
X-ray | 2D, used to observe bone |
CT Scan | 3D, soft tissue more visible |
MRI Scan | More detail than CT; colored image |
Ultrasound Images | Not as clear as CT Scan, safe for fetus |
Cells | Smallest living units in the human body |
Atoms | The smallest stable units of matter |
Coronal | Plane that divides the body into anterior and posterior sections |
Inguinal Region | The anatomical location of the groin |
Gluteal Region | The anatomical location of the buttocks |
Peritoneum | Serous membrane lining the abdominopelvic cavity |
