Question 1 of 5

Which type of cholesterol is considered the best for health?

Correct Answer: B

Rationale: High-density lipoprotein (HDL) is considered the best type of cholesterol for health. HDL helps remove excess cholesterol from the bloodstream, reducing the risk of heart disease. Conversely, low-density lipoprotein (LDL) is often referred to as 'bad' cholesterol as it can lead to plaque buildup in arteries. Very low-density lipoprotein (VLDL) and very high-density lipoprotein (VHDL) are not commonly used terms in cholesterol classification.

Which structure of the nervous system carries action potential in the direction of a synapse?

Correct Answer: B

Rationale: The correct answer is B: axon. The axon is a long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body towards other neurons or target cells, such as muscles or glands, including towards a synapse. The cell body contains the nucleus and other organelles but does not carry action potentials. While a neuron is the overall structural and functional unit of the nervous system, the axon is specifically responsible for transmitting action potentials.
