Explanation:

1. Endorphins are natural pain - relieving chemicals released by the brain in response to pain or stress. Dopamine is related to reward and motivation, morphine is an external drug, and ACH (acetylcholine) is a neurotransmitter for muscle movement and other functions.
2. The myelin sheath is a fatty substance that insulates the axon and speeds up nerve impulse transmission. Terminal sheath is not a standard term for this function, synapse is the gap between neurons, and the cell body is the part of the neuron that contains the nucleus.

Answer:

Question 1: B. endorphins
Question 2: A. myelin sheath
