No Spac... Heading 1 Paragraph Question 1 (5 points) Match as appropriate -Question options: If epinephrine (adrenalin) is injected into a patient you would expect the heart to beat faster and skeletal muscles to begin twitching due to direct stimulation of nicotinic receptors When released, acetylcholine will ALWAYS excite its target cell. In other words, acetylcholine excites skeletal, smooth, and cardiac muscle tissue. Threshold for a neuron is-55mV. If the neuron is normally resting at -75mV and you excite the neuron to-56mV, the neuron will generate an action potential True 2. False ? Dunng depolanaton, K leaves a neuron I don't know Action potentials start at the mon terminal and travel towards the soma in an anterograde fashion Acetylcholinesterase is an enzyme that synthesizes acetylcholine from an acetate and choline. In general, axons in gray matter are myelinated and axons in white matter are

Explanation / Answer

1.Is epinephrine is injected into patients blood you would expect the heart beat rate faster and skeleton muscles to begin twitching due to direct stimulus of nicotine receptors == TRUE.

2. When released acetylcholine will always excite the target cell in other words acetylcholine excite skeleton muscles and Cardiac muscle tissue = FALSE

3. Threshold for a neurone is -55 volt = TRUE

4. During depolarization potassium leaves the neurone = False

5. Action potential start at action terminal leave towards the Soma in anterograde fashion =TRUE

6.Acetylcholine is an enzyme that is synthesise is by acetylcholine from n Acetate and choline = false

7. In general exon in Grey matter is myelinated and exon in white matter is unmyelinated =TRUE

8. Without myelin and axon on potential will not reach the axon terminal = TRUE

9.At rest neurones have + 30 volte voltage = TRUE
