Answer:
B. The type of acetylcholine-activated channel in the post-synaptic membrane
Explanation:
Depending on the specific receptor, the same neurotransmitter can induce either an excitatory or inhibitory response. The ability of neurotransmitters to induce a response depends on their binding to specific receptors in the postsynaptic membrane,

11. Acetylcholine is both an excitatory and inhibitory ligand depending on the location of its receptor. What does Acetylcholine do that makes it "excitatory"? a. It causes a cell membrane to depolarize and produce Excitatory Post Synaptic Potentials b. It opens K+ ion channels when it binds to its receptors c. It causes a cell membrane to hyperpolarize 12. The bonding of Acetylcholine to its muscarinic receptors on smooth muscle causes gated K+ channels to close. This action is described...

Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments
described below...

Part I—The Hospital At last the day had come. Mr. Th ompson was having his wisdom teeth removed. He was tired of the aches and pains and the sight of his puff y face in the mirror every morning. He felt helpless, lying on the gurney watching the ceiling lights whiz by as he was being wheeled to surgery.

The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...
