Physiology
| Question | Answer |
|---|---|
| The type of network that accomplishes self-regulation, is a highly complex and integrated communication control system or network is required | Feedback control loop |
| normal reading or range is called the | Set Point |
| The impact of effector activity on sensors may be positive or negative. Therefore, homeostatic control mechanisms are categorized as | organs that are directly influenced by physiological variables or mechanisms. |
| Because negative feedback control systems oppose changes that are opposite in direction to the initial disturbance, they are | maintained in the homeostatic range |
| Which level of control operates at the cell level, often using genes and enzymes to regulate cell function? | intracellular regulation |
| Events that lead to an immune response to an infection or the formation of a blood clot are examples of | Positive feedback |
| Which of the following is a protein substance with no DNA or RNA and is thought to be the cause of mad cow disease? | Prion |
| The body’s thermostat is located in the: | Hypothalamus |
| Intracellular parasites that consist of DNA or RNA surrounded by a protein coat and sometimes by a lipoprotein envelope are called: | Viruses |
| Intrinsic control: | Is sometimes called autoregulation |
| the form of energy that cells generally use. | ATP |
| The carbon-containing molecules formed by living things are often called | Organic molecules |
| All proteins have which four elements? | carbon, oxygen, hydrogen, and nitrogen |
| A saturated fatty acid is one in which | all available bonds of its hydrocarbon chain are filled. You Answered |
| polymer of glucose that is sometimes referred to as animal starch? | Glycogen |
| The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of: | Filtration |
| Diffusion of particles through a membrane by means of a carrier molecule is called: | facilitated diffusion. |
| The small water channels in the cell membrane are called: | aquaporins. |
| Water will move through the cell membrane by: | Osmosis |
| The primary ossification center of a long bone is located: | Diaphysis |
| The cell organelles that synthesize organic matrix substances in bone formation are: | endoplasmic reticulum and Golgi apparatus. |
| Some synovial joints contain a closed pillow-like structure called a(n) | Bursa |
| Which subtype of fibrous joints is found only in the skull? | Suture |
