Drug addiction has reduced the number of receptors in the addict's neural synapses. How will this affect signal transduction at the synapse? Less neurotransmitter will be produced by the presynaptic cell. More neurotransmitter will be produce by the presynaptic cell. More ion channels will open in the postsynaptic cell. Fewer ion channels will open in the postsynaptic cell.

Drug addiction has reduced the number of receptors in the addict's neural synapses. This affects signal transduction at the synapse. Fewer ion channels will open in the postsynaptic cell.
What is a neural synapse?A neural synapse is formed by two neurons, such as a presynaptic neuron and a postsynaptic neuron, with a small space in between them. The neurotransmitters are delivered to the synaptic space by the presynaptic neuron via the fusion of vesicles, where they are received by the postsynaptic neuron. If any defects take place in the synaptic space or two of the neuron, then the message can't be transmitted properly.
here Drug addiction has reduced the number of receptors in the addict's neural synapses, and as a result, the receptors of the postsynaptic neuron can't receive all the molecules that are coming from the presynaptic neuron. Due to this, the impulse that is carried by the cell will not be transferred to the next neuron.
Hence, fewer ion channels will open in the postsynaptic cell. The last option is true.

If a poison is ingested that prevents the release of acetylcholine, which one of the following would occur at a myoneural junction? Sodium and potassium gates on the motor end plate will not close. Sodium and potassium gates on the motor end plate will not open. Sodium and potassium gates on the axon will not close. Sodium and potassium gates on the axon plate will not close.
Answer:
When a poison prevents the release of acetylcholine, at the myoneural junction occurs that sodium and potassium gates on the motor end plate will not open.
Explanation:
In cholinergic transmission, acetylcholine released by the presynaptic neuron binds to a specific receptor in the postsynaptic terminal. The effect of acetylcholine on its receptor produces the opening of sodium and potassium gates, whose exchange determines the transmembrane action potential.
If an acetylcholine release inhibitor —like a poison— is ingested, the absence of acetylcholine at the myoneural junction prevents the opening of the sodium and potassium gates. This results in the function of the effector, the muscle, not being performed.
The other options are not correct because obviously the action of acetylcholine is the opening of the sodium and potassium gates, not their closing.

Why do surgical cases tend to have a higher relative weight (RW), and in turn payment, than medical cases?
Answer:
Surgical cases tend to have a higher relative weight because they are generally more resource extensive than medical cases
Explanation:
Surgical cases involves procedures where patients go under the knife, they are usually the preferred in extreme conditions or when a faster rate of healing is required. Hence, the reason they posses higher relative weight and cost than medical procedures.
Surgical procedures such as appendectomy, coronary artery bypass and several other surgery classes are often delicate processes which involves working directly on the body system. Hence, they are very delicate. The requirement for surgical treatment are often associated with conditions that require fast rate of healing or conditions which have to be treated urgently.These are reasons why surgical cases are weighed higher than medical cases and hence more cost due to the delicate, risky and healing rate of the process.

A student simulates muscle contraction in a model using the following order of events:
1. Calcium pumps of the sarcoplasmic reticulum open.
2. Tropomyosin moves.
3. Calcium ions bind to troponin.
4. Myosin heads bend to attach to actin filaments.
Based on the order of steps in the student's model, will the muscle successfully contract?
Answer:
No, because tropomyosin cannot move before calcium ions bind to troponin
