| Question | Answer |
|---|---|
| Exteroceptors, | are located on or very near the body surface and respond most frequently to stimuli that arise external to the body itself. |
| Visceroceptors (interoceptors) | are located internally, often within the substance of body organs (viscera), and when stimulated provide information about the internal environment. |
| Proprioceptors | They are less numerous and generally more specialized than other internally placed receptors, and their location is limited to skeletal muscle, joint capsules, and tendons. |
| nociceptor | is used to describe the free nerve endings that serve as the primary sensory receptors for pain. |
| The immediate effect of a steroid hormone on a cell is | transcription of RNA. |
| Sensory impulses ending in what part of the CNS trigger imprecise or “crude” sensation awareness | Thalamus |
| The last step in the nonsteroid hormone mechanism of action is: | protein kinases activate other enzymes |
| The major hormone produced by the corpus luteum is | progesterone. |
| Tactile corpuscles | Meissner corpuscles, |
| Lamellar corpuscles | (Pacini corpuscles) are large mechanorecep-tors, which, when sectioned, show thick laminated connective tissue capsules. |
| Two types of stretch receptors, | muscle spindles and Golgi tendon receptors, |
| Somatic pain | fast, “take your breath away” pain associated with superficial injury or trauma |
| Visceral pain | dull or aching pain that develops more slowly over time and travels over B fibers |
| anosmia | complete lack of smell, can develop serious depression. |
| Filiform papillae | they do not contain taste buds but allow us to experience food texture and “feel” |
| Pyrogen molecules trigger the fever response by promoting the production of | prostaglandins. |
| Which antibody is synthesized by immature B cells and then inserted into their plasma membranes? | immunoglobulin M |
| Polysaccharides are hydrolyzed into disaccharides by enzymes known as | amylase |
