Study Cards
| Term | Definition |
|---|---|
| Anatomy | Study of structure and shape of the body and its parts |
| Physiology | Study of how the body and its parks work and function |
| Gross Anatomy | Large Structures, easily observed |
| Microscopic Anatomy | Only seen through a microscope |
| Integumentary system | Skin, external body covering, protects deeper inside body, nerve receptors |
| Skeletal System | Protection and support, muscle attachment for moving, blood cell forming, mineral storage |
| Muscular System | Allows body movement, maintains posture, creates heat |
| Nervous System | Fast-acting control system, brain, spinal cord, response to internal and external charges, activates muscles/glands |
| Endocrine System | Secretes hormones which aid in growth, reproduction, and metabolism |
| Cardiovascular System | Heart, blood vessels, transport materials in blood pumped by heart, oxygen, co2, nutrients and waste transported |
| Lymphatic | Returns fluid to blood vessels, disposes debris, involved in immunity, destroys bacteria and tumor cells |
| Respiratory | Keeps blood in oxygen and removes the CO2 |
| Digestive System | Breaks down food, allows for nutrient absorption, eliminates indigestible material |
| Urinary | Eliminates nitrogenous waste, maintains a balance in the body between acid and bases, regulates water and electrolytes level |
| Reproductive System | Produces offspring |
| Homeostasis | Stable operating conditions internally |
| Positive Feedback | Increases stimulus to push variable farther, only in blood clotting and the birth of a baby |
| Negative | Most homeostatic control mechanisms, shuts off og stimulus, or reduces it, works like a thermostat (shivering/sweating) |
| Superior | Towards the head |
| Inferior | Towards the toes/away from head |
| Anterior | Forward/At front |
| Posterior | Towards the back/behind |
| Medial | Towards the body midline |
| Lateral | Away from midline, towards the side |
| Intermediate | Between a more medial or lateral structure |
| Proximal | Close to the origin of the body |
| Distal | Farther from the body's origin |
| Superficial | Towards or at the body surface |
| Deep | Underneath the body surface |
