Exam 1

Question 1

Information in; neuronal decision making; chemically-gated Na+/K+ channels

Answer 1

Dendrites

Question 2

Action potential (electrical part of neuronal communication); voltage-gated Na+/K+ channels

Answer 2

Axon

Question 3

Identify the structures in a generalized synapse (pre-synaptic cell, post-synaptic cell, vesicle, neurotransmitter, vesicle)

Answer 3

Synapse

Question 4

Chemicals that mimic a NT by binding to the NTs receptor and stimulating the receptor resulting in the same effect as the NT

Answer 4

Agonists

Question 5

Chemicals that work against a NT by binding to the NT’s receptor but NOT allowing the receptor to be stimulated, blocking the effect of the NT

Answer 5

Antagonists

Question 6

Where on the flow diagram is normal disrupted, and what is the impact of the NT with Botulinum toxin?

Answer 6

SNARE Proteins do not change shape which doesn’t allow the vesicle to release ACH which then does not allow the muscle contraction.

Question 7

Where on the flow diagram is normal disrupted, and what is the impact of the NT with Sarin?

Answer 7

Inhibits acetylcholinesterase and impacts at neuromuscular junction.

Question 8

Where on the flow diagram is normal disrupted, and what is the impact of the NT with SSRI?

Answer 8

Selective serotonin reuptake inhibitor - blocks reuptake of serotonin.

Question 9

Where on the flow diagram is normal disrupted, and what is the impact of the NT with Cocaine?

Answer 9

Cocaine blocks reuptake of Dopamine and Norepinephrine. Blockage of norepinephrine uptake can have heart impacts.

Question 10

Where on the flow diagram is normal disrupted, and what is the impact of the NT with Bungarotoxin?

Answer 10

Acts as an antagonist for ACh receptors at neuromuscular junctin. Flaccid paralysis, they effect the SNARE proteins.

Question 11

Where on the flow diagram is normal disrupted, and what is the impact of the NT with methamphetamines?

Answer 11

Meth stimulates release of DA from axon terminal. Inhibits reuptake of DA, NE, and E from synapse. Results in rapid down regulation of DA receptors.

Question 12

Where on the flow diagram is normal disrupted, and what is the impact of the NT with alcohol?

Answer 12

Alcohol has similar effects, acting as GABA agonists especially in areas of emotion, fear, and memory.

Question 13

Information comes in via the dorsal root and information leaves via the ventral root.

Answer 13

C

Question 14

Collection of neural cell bodies in the PNS

Answer 14

Ganglion

Question 15

Fight or flight (or freeze)
Characterized by freeing energy for use, vasoconstriction, and prioritization of system functions for staying alive for 15 min.

Answer 15

Sympathetic division

Question 16

Relax and repose; Characterized by energy storage and system functions for long term survival?

Answer 16

Parasympathetic division

Question 17

1 neuron, using nicotinic ACh receptors at synapse

Answer 17

Somatic motor

Question 18

Parasympathetic: 2 neurons, using nicoticic ACh receptors at pre-ganglionic synapse, and muscarinic ACh receptors at post-ganglionic synapse.
Sympathetic; using nicotinic ACh receptors at pre-ganglionic synapse, and noradrenergic (NE) receptors at post-ganglionic synapse.

Answer 18

Autonomic Motor
