Depolarization, Summation, and Neural Pathways Questions And Answers Depolarization - ANS-Action potential depolarizes synaptic knob Secondary Messenger - ANS-Ca enters axoplasm triggering norepi First Messenger - ANS-norepi binds to receptor site causing adenyl cyclase within the cytoplasm to catalyze the formation of cyclic AMP from ATP Second Messenger - ANS-cyclic AMP opens ion channels allowing NA to depolarize membrane Summation - ANS-Integration of EPSP's and IPSP's to reach depo...

HUBS 191 Nervous System Latest Update 100% Solved Resting membrane potential -70mV Open Voltage gated ion channels are ? at -60mV Inactive Voltage gated ion channels are ? at+30mV Na+ Extracellular fluid as a high ? concentration and is therefore positive in comparison to the ICF K+ Intercellular fluid has a high ? concentration and is therefore slightly negative in comparison to the ECF Depolarisation The change from a negative resting potential to a positive action poten...

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...

Bio 669 Quiz 2 |Gradient Potential| Neurons| Electrons| Complete Mock Exam 2024/2025 What is the primary function of neurons in the nervous system? Neurons transmit signals throughout the body to facilitate communication between the brain and other body parts. What is the resting membrane potential of a typical neuron? Approximately -70 mV. How does the concentration gradient influence ion movement across a neuron's membrane? Ions move from areas of high concentration to areas...

How Neurons Integrate Information- Through dendritic spines, a neuron can establish more than 50,000 connections to other neurons - Nerve impulses traveling from other neurons bombard the receiving neuron with all manner of inputs (excitatory and inhibitory) - The cell body, located between the dendritic tree and its axon, can receive inputs from many other neurons Saltatory ConductionMyelin and Node of Ranvier Node of RanvierPart of an axon that is not covered by myelin Tiny gaps in the myeli...

__ spindle afferents encircle intrafusal muscle fibers and report changes in muscle length and speed of extrafusal fiber contraction - 1a A bundle of nerve fibers + intervening endoneurium bounded by a ring of perineurium is called ____. The blood-nerve barrier protects this compartment. - Endonuerial Compartment a condition caused by damage to the thalamus resulting in burning or tingling sensations and possibly hypersensitivity to things that would not normally be painful such as light to...

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

Biology 1107 Final Exam Study Guide (University Of Connecticut) 2024 along the length of the axon c. Action potential needs to be regenerated by the presence of more voltage gated sodium and potassium channels along the length of the axon d. So if axon is damaged, you would not have transmission of AP, it would never drive at the axon terminal and never release a neurotransmitter e. Myelin- a fatty cell type that wraps around the axon, allowing for jumping of action potential alon...

LH (Lutenizing hormmone) is produced where? - Pituitary gland (anterior pituitary) What are the benefits of presurgical mapping in epilepsy surgery or tumor removal cases? (select all that apply) – *minimize functional deficit *provide data for intra-operative guidance and maximize resection *assess risk and benefit of surgery *plan surgical approach Why is it important to record eye movements, EKG, EMG & respirations on neonatal EEGs? - Which of the following electrophysiological ev...
