Anatomy 2401 Ch. 1
Unit 1
| Term | Definition |
|---|---|
| Anatomy | The study of structure |
| Physiology | The study of function |
| Palpation | Feeling a structure with the hands |
| Auscultation | Listening to the natural sounds made by the body |
| Percussion | Tapping on the body to listen for abnormalities such as pockets of fluid, air, or scar tissue |
| Dissection | Carefully cutting and separating tissues to reveal their relationships |
| Comparative Anatomy | The study of multiple species in order to examine similarities and differences and analyze evolutionary trends |
| Gross Anatomy | Structure that can be seen with the naked eye — whether by surface observation, radiology, or dissection |
| Histology | Microscopic examination of tissues for signs of disease |
| Cytology | Study of structure and function of individual cells |
| Ultrastructure | Fine detail down to the molecular level revealed by the electron microscope |
| Comparative Physiology | The study of how different species have solved problems of life such as water balance, respiration, and reproduction |
| Who is considered the “Father of Medicine”? | Hippocrates |
| Who designed the compound microscope? | Robert Hooke |
| The scientist that concluded all organisms are composed of cells, which later became the foundation of cell theory, is ____. | Theodor Schwann |
| Scientific Method | Certain habits of disciplined creativity, careful observation, logical thinking, and honest analysis of one’s observations and conclusions. |
| The Inductive Method | a process of making numerous observations until one feels confident in drawing generalizations and predictions from them |
| Sample size | The number of subjects used in a study |
| Control group | Subjects in an experiment much like the treatment group that does not get tested on |
| Psychosomatic effects | Effects of the subject’s state of mind on his or her physiology |
| Pacebo | Substance with no significant physiological effect on the body |
| Double-blind method | Neither the subject or the administrator of the treatment knows whether the subject is receiving the experimental treatment or the placebo |
| Peer review | Critical evaluation by other experts in the same field |
| Law of nature | Generalization about the predictable ways in which matter and energy behave |
| Evolution | The change in genetic composition of a population of organisms |
| Natural selection | The hereditary advantages which some individuals in a species have over their competitors |
| Selection pressures | Natural forces that promote the reproductive success of some individuals more than others |
| Adaptations | Features of anatomy, physiology, and behavior that evolve in response to selection pressures and enable an organism to cope with the challenges of its environment |
| Arboreal | Treetop habitat |
| Prehensile | Able to grasp objects by encircling them with the thumb and fingers |
| Stereoscopic Vision | Depth perception (provides better hand-eye coordination in catching and manipulating prey and aids in judging distances when leaping tree to tree. Secondary to the adaptation of forward-facing eyes) |
| List the Hierarchy of Complexity from most complicated to least complicated | Organism, organ system, organ, tissues, cells, organelles, molecules, atoms |
| Organism | A single, complete individual |
| Organ system | group of organs with a unique collective function, such as circulation, respiration, or digestion |
| Organ | Structure composed of two or more tissue types that work together to carry out a particular function |
| Tissue | Mass of similar cells and cell products that forms a discrete region of an organ and performs a specific function |
| Cells | Smallest unit of an organism that carry out all the basic functions of life |
| Organelles | Microscopic structures in a cell that carry out its individual functions |
| Eight Characteristics of Life: | Organization, Cellular Composition, Metabolism, Responsiveness, Development, Reproduction, Evolution |
| Metabolism | Sum of all internal chemical change |
| Homeostasis | The body’s ability to detect change, activate mechanisms that oppose it, and thereby maintains relatively stable internal conditions |
| Negative Feedback | Process in which the body senses a change and activates mechanisms that negate or reverse it |
| Positive Feedback | Self-amplifying cycle in which a physiological change leads to even greater change in the same direction |
| Gradient | Difference in chemical concentration, electrical charge, physical pressure, temperature, or other variable between one point and another |
| Pressure Gradient | Difference in pressure which cause a movement from high to low pressure |
| Concentration Gradient | Difference in concentration of chemicals which causes a movement from high to low concentration |
| Electrical Gradient | Difference in electrical charge which causes charges particles to move from an area of positive charge to an area of negative charge |
| Electrochemical Gradients | The flow of ions governed by a combination of concentration and electrical charge differences between two points |
| Thermal Gradient | Flow of heat down to a cooler area |
