Sensory perception 1.)conscious process of selecting, organizing, and interpreting data from senses into meaningful info 2.)Perception is influenced by the intensity, size, change, representation of stimuli, past experiences, knowledge, attitudes. Stimulus 1.)agent or act that stimulates a nerve receptor Impulse conduction process - sensory functioning also do receptors respond to many stimuli or just one? 1.)receptor receives stimuli, translates it to impulse 2.)impulse travels along nerve pa...

NSG 531 Rush Advanced Pharmacology: Exam 3 Questions With Correct Answers Latest Updated 2024/2025 / Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean ...

Anatomy & Physiology: Nerve Impulse Conduction What is the first step in nerve impulse conduction? - ANS Nerve fiber has resting potential by diffusion of Na and K down their concentration gradients. What is the second step in nerve impulse conduction? - ANS Neurons receive stimulation, causing local potentials which may reach threshold. What is the third step in nerve impulse conduction? - ANS Sodium channels in a local region of the membrane open. What is the ...

Repolarization ANS:...

How do local anesthetics block the nerve impulse from reaching the brain? By permanently depolarizing the nerve cell membrane By overwhelming influx of fluoride ions By blocking sodium channels, thereby preventing nerve cell depolarization and impulse propagation By causing massive neurotransmitter release without uptake. By blocking sodium channels, thereby preventing nerve cell depolarization and impulse propagation How do local anesthetics stop working? By diffusion of the lo...
