Chapter 1 Human Body
Structure & Function
| Question | Answer |
|---|---|
| Anatomy | Study of the structure of an organism & the relationship of its parts; done by dissection |
| Physiology | Study of the functions of living organisms & their parts |
| Pathology | scientific study of disease; uses principles of anatomy and physiology to determine nature of diseases |
| cells | smallest living units of structure and function in the body |
| tissues | organization of many cells that act together to perform a common function |
| organs | group of several different kinds of tissues arranged so they can act together as a unit to perform a special function |
| Systems | organization of varying number and kinds of organs arranged so that they can together perform complex functions of the body |
| supine position | body is lying face upward |
| prone position | body is lying face downward |
| superior (S) | toward the head; upper; above |
| inferior (I) | toward the feet; lower; below |
| anterior (A) | front; in front of |
| posterior (P opposite A) | back; in back of |
| ventral | toward the belly (can use in place of anterior) |
| dorsal | toward the back (can be used in place of posterior) |
| medial (M) | toward the midline of the body |
| lateral (L opposite M) | toward the side of the body or away from the midline |
| proximal (P opposite D) | toward or nearest the trunk of the body or nearest the point of origin of one of its parts |
| distal (D) | away from or farthest from the trunk or the point of origin of a body part |
| superficial | nearer the surface |
| deep | farther away from the body surface |
| R | right |
| L | left |
| sagittal | lengthwise plane running from front dividing body into L and R parts |
| frontal/coronal | lengthwise plane running side-to-side; divides body into anterior and posterior parts |
| transverse/horizontal | divides body into upper and lower portions |
| dorsal cavity | 1) cranial cavity/brain 2) spinal cavity/spinal cord |
| axial body portion | head, neck, torso/trunk |
| appendicular body portion | upper and lower extremities |
| atrophy | degenerative process resulting from disuse |
| homeostasis | relative constancy of the internal environment |
| feedback loop | a highly complex and integrated communication control system classified as negative or positive |
| negative feedback loops | opposes or negates change in a controlled condition to cause a return to normal |
| positive feedback loops | stimulatory; temporarily amplify or reinforce change that is occurring. Rate increases until something causes it to stop |
| sensor | detector of changes in feedback loop |
