Question

question 26 (1 point)
the autonomic nervous system:
a) controls voluntary muscles
b) is involved in conscious thought
c) is the centre for learning
d) controls unconscious life - sustaining activities
e) none of the above
question 27 (1 point)
acetylcholine works:
a) by effecting in the nucleus of a cell and starting transcription
b) in neuromuscular junction
c) initiates the formation of steroids
d) is important in the action potential

Explanation:

For Question 26:
The autonomic nervous system is responsible for regulating involuntary (unconscious) processes that are essential for life - such as heart rate, digestion, and breathing. Voluntary muscle control is by the somatic nervous system. Conscious thought and learning centers are in the brain (e.g., cerebral cortex).
For Question 27:
Acetylcholine is a neurotransmitter that acts at neuromuscular junctions (between nerves and muscles) to transmit signals for muscle contraction. It does not act in the nucleus to start transcription (that's more related to hormones like steroid - derived ones which can enter the nucleus). It does not initiate steroid formation. While it is involved in some aspects of the nervous system, it is not the main player in the general action potential (sodium and potassium channels are more fundamental for the basic action potential in neurons, but acetylcholine is crucial at the neuromuscular junction for the signal from nerve to muscle).

Answer:

Question 26: D. controls unconscious life - sustaining activities
Question 27: B. in neuromuscular junction
