The basic structural unit of the nervous system is the neuron, which is a nerve cell that transmits information to other cells. This is important in biology and understanding how the nervous system works.
The basic structural unit of the nervous system is the neuron. Neurons, also known as nerve cells, are the primary cells of the nervous system that transmit information to other nerve cells, muscle, or gland cells. These specialized cells consist of a nucleus, dendrites, an axon, and synapses. The axon conducts electrical impulses away from the neuron's cell body, but it is the neuron itself that forms the fundamental unit of the nervous system, not the axon or any type of blood cell.

Answer:
I am answering the second one btw, so here we go
A gradually but completely withdrawing from alcohol or drugs.
Answer: True
Explanation:
Ischemia is the reduction in blood flow to a tissue resulting in decreased oxygen and nutrient supplies to the tissue which may lead to cell death if not reversed.
Risk factors to ischemia includes:
1. Vascular diseases
2. Trauma
3. High blood pressure
4. Tobacco
5. Physical inactivity
6. High cholesterol.
Ischemia can be acute or chronic depending on its course of action. Acute ischemia occurs when there is a sudden decrease in the flow of blood to a tissue while chronic ischemia occurs when there is a gradual decrease in blood flow to a tissue.
Ischemia can be reversible when blood flow to the tissue returns. When irreversible, it leads to cell death.
a. True
b. False
Correct answer choice is :
As time raises after you have done training the pulse rate decreases. This occurs because energy is not being used as fast, therefore, cells need less energy hence the heart does not need to pump blood as much as less oxygen is needed for it to be used as energy. Within 10 minutes after training the heart rate should drop below 100 or it can be very critical.
