A given receptor is described based on each classification criterion: receptor distribution, stimulus origin, and modality of stimulus. The eyes, for example, are because they are located in the head (receptor distribution); because they detect stimuli outside the body (stimulus origin); and because they detect light (modality of stimulus). In comparison, receptors that detect stretch of blood vessels are classified as because they are distributed throughout the body, because they detect stimuli within the body, and because they detect changes in distension of the organ wall.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
