sympathetic nervous system

Accepted Answer

### Question 1
# Brief Explanations:
The central nervous system consists of the brain and spinal cord. The peripheral nervous system is outside this, the spinal cord is separate from the brain, and the cerebellum is a part of the brain. So the brain is part of the central nervous system.
# Answer:
a. the central nervous system

### Question 2
# Brief Explanations:
A neuron has axon, dendrite, and cell body. Axon transmits signals, dendrite receives, and cell body contains the nucleus. So all of these are parts of a neuron.
# Answer:
d. all of the above

### Question 3
# Brief Explanations:
The cerebellum's function is to smooth and coordinate skeletal muscle movements. Pons is for relaying, midbrain for visual/audio reflexes, cerebrum for higher functions. So the cerebellum is correct.
# Answer:
b. cerebellum

### Question 4
# Brief Explanations:
The autonomic nervous system has two divisions: sympathetic (fight - or - flight) and parasympathetic (rest - and - digest). The other options mix incorrect systems (peripheral, central, somatic are not part of autonomic's composition).
# Answer:
c. the sympathetic and parasympathetic nervous systems

### Question 5
# Brief Explanations:
Motor neurons carry signals from the spinal cord to muscles to cause movement. Sensory neurons carry to the spinal cord, interneurons are within the spinal cord, and nerve impulses are signals, not neurons. So motor neurons are correct.
# Answer:
a. motor neurons

### Question 6
# Brief Explanations:
The nervous system has two main divisions: central (brain and spinal cord) and peripheral (nerves outside central). So the missing term is peripheral nervous system.
# Answer:
peripheral nervous system

### Question 7
# Brief Explanations:
The central nervous system is defined as the brain and spinal cord. So this is the correct term.
# Answer:
central nervous system

### Question 8
# Brief Explanations:
The cerebrum is responsible for higher cognitive functions like learning, speaking, writing, and music. The other terms (brain stem, etc.) have different functions.
# Answer:
cerebrum

### Question 9
# Brief Explanations:
The brain stem connects the spinal cord to the rest of the brain and regulates basic life functions. So this is the correct term.
# Answer:
brain stem

### Question 10
# Brief Explanations:
The sympathetic nervous system triggers the “fight or flight” response, preparing the body for stress. The parasympathetic is for relaxation, so sympathetic is correct.
# Answer:
sympathetic nervous system
