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 |
