Cold temperature E. An odorant molecule Which of these would be most likely to stimulate a chemoreceptor? A. An odorant molecule B. Physical distortion of cells C. Vibration D. Cold temperature E. Hot temperature All sensory pathways except olfaction first travel to the , which acts as a relay and processing station. A. Cerebrum B. Thalamus C. Cerebellum D. Pons E. Medulla oblongata Convergence describes how multiple presynaptic sensory neurons synapse on one post-synaptic neuron. Which of the following is the most likely result? A. A stronger stimulus intensity is needed to activate the sensory receptors. B. Incoming stimuli will not be processed in the CNS. C. The individual receptive fields for the presynaptic sensory neurons overlap to form a secondary receptive field. D. Sensory transduction will not occur. Tonic receptors A. Quickly adapt to a stimulus and "turn off". B. Slowly decrease the frequency of action potentials, but continue to fire as long as a stimulus is present. C. Always decrease to the point where no action potentials are being generated. D. All of these are correct.

Interacellular receptors bind  a. Hydrophilic molecules  B. Cell membrane receptors  c. Second messengers such as Camp  d. Protein hormones  e. Small signals that can diffuse through the cell membrane

Which direction would a competitive reversible antagonist (plus agonist) shift the dose-response curve of the agonist? Group of answer choices A.To the left B.To the right C.Down D.Up E.To the right and possibly down

When a patient has a severe allergic reaction, a common prescribed drug is epinephrine. Which of the follow best explains the effects of epinephrine on a patient experiencing a severe allergic reaction?   A epinephrine binds to the beta-1 receptor.  Activating the beta-1 receptor causes vasodilation and bronchoconstriction. Bronchoconstriction allows the patient to breath by relaxing the smooth muscle that is constricting the airway.  B Epinephrine binds to the beta-2 receptor. Activating the beta-2 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath easier by relaxing the smooth muscle that is constricting the airway. C Epinephrine binds to the alpha-1 receptor. Activating the alpha-1 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath by relaxing the smooth muscle that is constricting the airway.  D Epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and…

Asthma rescue inhalers are used when a person is having an asthma attack. The active ingredient is called a sympathomimetic, a substance that mimics the effects of the sympathetic nervous system. How would this help a person who is experiencing problems with breathing due to asthma? They bind to alpha receptors on blood vessels in the lungs. They bind to muscarinic receptors on airway smooth muscle.. The drug binds to beta 2 receptors on respiratory bronchiole smooth muscle. They bind to nicotinic receptors on airways in the lungs.
