Intro. to Anatomy
Anatomical terms, Homeostasis
| Question | Answer |
|---|---|
| Anatomy | Study of internal and external structures of the body and the physical relationships among body parts. |
| Physiology | the study of how living organisms functions. |
| Organ | consist of two or more tissues working in combination to perform several functions |
| Tissue | a group of cells and cell products working together to perform one or more specific functions. |
| Cells | are the smallest living units in the body |
| Atoms | The smallest stable units of matter, can combine to form molecules with complex shapes. |
| Organ system | Consist of organs that interact to perform a specific range of functions. |
| Integumentary System | Protects body from environmental hazards, controls body temperature |
| Skeletal System | Supports, protects soft tissues, stores minerals; forms blood cells |
| Muscular System | Moves and supports body; produce heat |
| Nervous System | Direct immediate response to stimuli, usually by coordinating the activities of other organ systems |
| Endocrine System | Direct long-term changes in the activites of other organ systems |
| Cardiovascular System | Transport Cells and dissolved mineral internally, including nutrients, wastes and gases |
| Lymphatic System | DEfends against infection and disease |
| Respiratory System | Delivers air to sites where gas exchange can occur between the air and circulating blood |
| Digestive System | Processes food and absorbs organic nutrients, minerals, vitamins, and water |
| Urinary System | Eliminates excess water, salts,and waste products;control of pH |
| Reproductive System | Produces sex cells and hormones |
| Homeostasis | the presence of a stable environment inside the body |
| Receptor | sensitive to a particular environmental change or stimulus |
| Control Center | receives and processes the information supplied by the receptor, which sends out commands |
| Effector | Responds to these commands by opposing the stimulus |
| Negative Feedback | Minimizes change. Stimulus triggers an automatic response that corrects the current situation |
| Positive feedback | an initial stimulus produces a response that exaggerates or enhances a change in the original conditions, rather than opposing it. |
| Supine | face up, lying down in anatomical position |
| Prone | face down, lying down in anatomical position |
| Anterior | The front surface of the human body |
| Posterior | The back surface of the human body |
| Cranial | the head |
| Superior | above; at a higher level |
| caudal | the tail |
| inferior | below; at lower level |
| Medial | Toward the body's longitudinal axix; toward midsaggital plane |
| Lateral | away from the body's longitudinal axis; away from the midsaggittal plane |
| Proximal | toward an attached base |
| Distal | away from an attached bas |
| Superficial | At, near or relatively close to the body surface |
| Deep | Farther from the body surface |
| Transverse | perpendicular to long axis |
| Saggital | Parallel to long axis |
| Frontal | Parallel to long axis |
