Neural Control and Coordination Chapter-Wise Test 13

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which division of the nervous system is responsible for the "rest and digest" response?

Somatic nervous system
Parasympathetic nervous system
Sympathetic nervous system
Central nervous system
2

The parasympathetic nervous system promotes digestion, relaxation, and energy conservation.

Which part of the brain is responsible for processing auditory information?

Occipital lobe
Parietal lobe
Temporal lobe
Frontal lobe
3

The temporal lobe of the cerebrum is responsible for processing auditory information.

Which of the following statements about neurotransmitters is correct?

Acetylcholine is an excitatory neurotransmitter at neuromuscular junctions.
Neurotransmitters are not required for synaptic transmission.
Neurotransmitters pass through the postsynaptic membrane.
Dopamine is only involved in muscle contractions.
1

Acetylcholine is an excitatory neurotransmitter that stimulates muscle contractions at neuromuscular junctions.

Which structure in the nervous system acts as a bridge between the spinal cord and various parts of the brain?

Medulla oblongata
Pons
Thalamus
Cerebellum
2

The pons contains nerve fibers that connect different regions of the brain and relay information between the brain and spinal cord.

Which neurotransmitter is associated with the transmission of pain signals?

Dopamine
Serotonin
Substance P
Acetylcholine
3

Substance P is involved in transmitting pain signals from sensory neurons to the central nervous system.

Which division of the autonomic nervous system promotes digestion and energy conservation?

Somatic nervous system
Parasympathetic nervous system
Sympathetic nervous system
Central nervous system
2

The parasympathetic nervous system is responsible for "rest and digest" functions, promoting digestion and energy conservation.

Which part of the brain is responsible for the regulation of emotions and motivation?

Thalamus
Limbic system
Medulla oblongata
Cerebellum
2

The limbic system, including structures like the amygdala and hippocampus, plays a crucial role in emotions and motivation.

Which of the following ions is required for the release of neurotransmitters from the presynaptic terminal?

Sodium (Na⁺)
Calcium (Ca²⁺)
Potassium (K⁺)
Chloride (Cl⁻)
2

Calcium ions (Ca²⁺) enter the presynaptic neuron, triggering neurotransmitter release into the synaptic cleft.

Which of the following statements about neurotransmitters is incorrect?

Dopamine is a neurotransmitter involved in mood regulation.
Acetylcholine is involved in muscle contraction.
All neurotransmitters have an excitatory effect.
Serotonin plays a role in sleep and mood regulation.
3

Neurotransmitters can be excitatory (e.g., glutamate) or inhibitory (e.g., GABA), depending on the receptor they bind to.

Which of the following statements about the central nervous system (CNS) is correct?

It consists of the brain and spinal cord
It includes cranial and spinal nerves
It controls only involuntary functions
It is primarily involved in hormone secretion
1

The central nervous system (CNS) consists of the brain and spinal cord, which process and coordinate information.
