Basic Anatomy
| Question | Answer |
|---|---|
| Anatomy | Study of structure and shape of the body. |
| Physiology | Study of functions of the body. Structure determines function. |
| 1: Chemical Level | Atoms |
| 2: Cellular Level | Cells |
| 3: Tissue Level | Tissues |
| 4: Organ Level | Organs |
| 5: Organ Systems | Skin, cardiovascular |
| 6: Organism | Shoop, etc. |
| Integumentary System: Includes | Skin, hair and nails. |
| Integumentary System: Function | Waterproofs the body, cushions and protects, excretion (sweat and tears). Regulates body temp. Pain, pressure and temp. receptors located here. |
| Skeletal System: Includes | Bones, cartilages, ligaments and joint. |
| Skeletal System: Function | Support and protect organs, provides framework for muscles, stores minerals. Blood cells are formed in bones. |
| Muscular System: Includes | Skeletal, cardiac, smooth, muscle |
| Muscular System: Function | Allows body to move. Facial expressions, posture, produces heat. |
| Nervous System: Includes | Brain, spinal column, nerves, and sensory receptors. |
| Nervous System: Function | Control system of body, responds to changing environment. Detects changes inside and outside the body. |
| Endocrine System: Includes | Pituitary, thyroid, parapthyroid, adrenals, thymus, pancreas, pineal, ovaries and testes glands. |
| Endocrine System: Function | Maintain homeostasis, secrete hormones. |
| Cardiovascular System: Includes | Heart, blood vessels. |
| Cardiovascular System: Function | Blood vessels transport blood throughout the body. Heart pumps blood. |
| Lymphatic System: Includes | Lymph nodes, Lymphatic vessels, spleen, tonsils. |
| Lymphatic System: Function | Cleans the body and blood. Immune cells found here. |
| Respiratory System: Includes | Larynx, lungs, pharynx, trachea, nasal passages, bronchi. |
| Respiratory System: Function | Keeps blood constantly supplied with oxygen and removes carbon dioxide. |
| Digestive System: Includes | Esophagus, stomach, mouth, intestines, rectum. |
| Digestive System: Function | Breaks down food into usable units for energy. Ends with excrement. |
| Urinary System: Includes | Kidneys, bladder, ureters and urethra. |
| Urinary System: Function | Eliminate waste from body. Regulates water and salt balance of blood. |
| Reproductive: Includes | Testes, penis, ovaries, uterus, vagina. |
| Reproductive: Function | Production of offspring. |
| Things we NEED to survive | Water, Oxygen, Appropriate body temp., Nutrients, Atmospheric pressure, Homeostasis. |
| Homeostasis | Maintenance of a stable internal environment. |
| Homeeostatic Imbalance | A disturbance resulting in disease. |
| Negative Feedback | Includes most homeostatic control mechanisms. Shuts off original stimulus, or reduces its intensity. |
| Positive Feedback | Increases the original stimulus to push the variable farther. Blood clotting, birth of a baby. |
| Anatomical Position | Standing erect with palms facing forward. |
| Superior | Towards head/above. |
| Inferior | Towards feet/below. |
| Anterior/Ventral | Front. |
| Posterior/Dorsal | Back. |
| Medial | Towards the middle. |
| Lateral | Towards the outside. |
| Proximal | Closer to point of origin. |
| Distal | Further from point of origin. |
| Superficial | On the surface. |
| Deep | Away from surface, internal. |
| Body Plane: Median | Divides the body into left and right parts. |
| Body Plane: Frontal | Divides the body into anterior and posterior parts. |
| Body Plane: Transverse | Divides the body into superior and inferior parts. |
| Cranial Cavity | Brain |
| Spinal Cavity | Spinal Chord. |
| Thoracic | Heart, lungs, etc. |
| Abdominal | Digestive |
| Pelvic | Urinary and reproductive. |
