BIOL 3240 Exam 2 | Complete Solutions (Verified) The process whereby a neuron communicates with another cell, which can be another neuron or a muscle cell Synaptic transmission Who was the first person to coin the term "synapse?" Charles Sherrington The region between pre and post synaptic cells zone of apposition (chemical/electrical) synapses are used to generate rapid and stereotyped depolarizing signals Electrical (chemical/electrical) synapses are capable of variable signaling, mediat...

presynaptic neurons - ANSWER can form synapses with a post synaptic neuron axosomatic - ANSWER Interaction between axon and some (or cell body) axoaxonic synapses - ANSWER Interaction between axon of one neuron and the axon of another axodendritic - ANSWER interaction between axon and dendrite electrical syanpses - ANSWER via gap junctions between two adjacent neurons allows bidirectional transmission very quick

NSC EXAM #1 QUESTIONS & ANSWERS 2024/2025 the big picture of synaptic transmission - ANSWERSthumbtack causes mechanically-gated Na+ channels to open, sending an action potential down the axon using voltage-gated Na+/K+ channels, causing voltage-gated Ca2+ channels to open and activate snare proteins that bind synaptic vesicles to the membrane and causes release of NT importance of synapses - ANSWERSrich diversity allows for complex behavior; place where most psychoactive drugs act; defec...

OCCTH 585 Neuro Questions With Complete Solutions. True or False: Rehabilitation specialists are able to foster functional recovery in the nervous system without knowledge of the biological basis of injury and repair. - correct answer.False It is argued that a biological basis of injury and repair is essential for rehabilitation specialists to know and understand in order to be effective healthcare providers. In simple terms, what is neuroplasticity? - correct answer.The brain'...

Afferent - Towards (towards the spinal cord) Efferent - Away From (away from the spinal cord) Which nerves are incapable of regeneration? - Neurons in the Central Nervous System (CNS) do not divide and injury causes permanent loss. Which injury to nerves has better outcomes? Crushed or Severed/Cut - Crushed nerves recover better How do peripheral nerves repair themselves? - Axonal Reaction Name 8 local changes that occur when an axon is severed - 1. Cut end retracts and the axolemma cove...

Excitatory synapses make the post-synaptic cell less likely to fire. False The neural tissues are: Spinal cord, sensory neurons, and brain How do the glial cells (i.e., myelin sheath) speed up the firing of neurons? The cell wraps extensions of a fatty insulating substance (myelin) around the axons of neurons. The action potential is: A result of the movement of ions. Receptors are made from membrane-bound polyribosomes. True List the 4 types of glial cells and list a phrase to ...

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...

Step 1: The Chemical Synapse An action potential arrives at the end bulb. Step 2: The Chemical Synapse Ca++ enters the presynaptic terminal. Step 3: The Chemical Synapse Ca++ interacts with the synaptic vesicle and fuses with the presynaptic membrane. Step 4: The Chemical Synapse Neurotransmitter is released and binds to the postsynaptic transmitter receptor. Step 5: The Chemical Synapse Receptor protein undergoes a change in shape that allows ions to flow. Step 6: The Chemical Synapse...
