T or F: Potassium ions are at high concentrations inside of cells, including neurons - ANSWER-True The action potential is a result of: - ANSWER-the movement of ions The post-synaptic cell can be: - ANSWER-in glands, muscle cells and neurons Th resting potential of a neuron is - ANSWER--60mV T or F: The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon terminal - ANSWER-false T or F: Voltage gated ion channels open when a protein binds ...

NSC 3361 Exam 1 Questions and Answers All Correct Sequence of transmission at chemical synapse - Answer-1. Action potential travels down axon to axon terminal. 2. Voltage-gated calcium channels open and Ca2+ enters. 3. Synaptic vesicles fuse with membrane and release transmitter into the cleft. 4. Transmitter binds to post-synaptic receptor, causing EPSP or IPSP. 5. May bind to the presynaptic autoreceptors, decreasing release. 6. Neurotransmitter is inactivated by degradation or reuptak...

3 steps of how the nervous system functions 1. Sense organs receive info 2. Brain and spinal cord process this info 3. Brain and spinal cord issue commands to muscles and gland cells synaptic delay time from the arrival of a signal at the axon terminal of a presynaptic cell to the beginning of an action potential in the postsynaptic cell 2 main division of the nervous system and organs of each Central Nervous System (brain and spinal cord) Peripheral nervous system (nerves and gan...

1. A patient asks a nurse, "What are neurotransmitters? My doctor says mine are out of balance." The best reply would be: a. "You must feel relieved to know that your problem has a physical basis." b. "Neurotransmitters are chemicals that pass messages between brain cells." c. "It is a high-level concept to explain. You should ask the doctor to tell you more." d. "Neurotransmitters are substances we eat daily that influence memory and mood.": B Stating that neur...

effector proteins Ans: proteins that have some direct effect on the behavior of the target cell excitable dendrites Ans: Boosts EPSPs EPSP summation Ans: a simple form of synaptic integration whereby excitatory postsynaptic potentials combine to produce a larger postsynaptic depolarization synaptic integration Ans: process by which multiple synaptic potentials combine within one postsynaptic neuron voltage gated channels Ans: open and close in response to changes in membrane potential...
