Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which part of the brain is primarily responsible for coordinating voluntary muscle movements?

Cerebellum
Thalamus
Medulla oblongata
Hypothalamus
1

The cerebellum is responsible for the coordination of voluntary muscle movements, posture, and balance.

Which part of the nervous system directly controls voluntary muscle movements?

Autonomic nervous system
Somatic nervous system
Sympathetic nervous system
Parasympathetic nervous system
2

The somatic nervous system controls voluntary movements by transmitting impulses from the CNS to skeletal muscles.

Which of the following statements about the cerebellum is incorrect?

It helps in maintaining posture and balance.
It regulates digestion and metabolism.
It plays a role in fine motor control.
It processes sensory information related to movement.
2

The cerebellum is responsible for coordination, balance, and movement, but digestion and metabolism are regulated by the hypothalamus and medulla oblongata.

Which of the following neurotransmitters is inhibitory and helps reduce neural excitability?

Acetylcholine
Dopamine
GABA
Serotonin
3

GABA (Gamma-Aminobutyric Acid) is an inhibitory neurotransmitter that reduces neural excitability.

Which of the following parts of the brain controls coordination and balance?

Medulla oblongata
Cerebrum
Cerebellum
Thalamus
3

The cerebellum is responsible for maintaining balance and coordinating muscle movements.

Which division of the autonomic nervous system is active during stress and emergencies?

Somatic nervous system
Parasympathetic nervous system
Sympathetic nervous system
Central nervous system
3

The sympathetic nervous system is responsible for the "fight-or-flight" response during stressful situations.

Which neurotransmitter is primarily associated with mood regulation and is often linked to depression?

Dopamine
Serotonin
Acetylcholine
GABA
2

Serotonin is involved in mood regulation, and its deficiency is often linked to depression.

Which neurotransmitter is primarily involved in reducing neural excitability?

Dopamine
Acetylcholine
Serotonin
GABA
4

GABA (Gamma-Aminobutyric Acid) is an inhibitory neurotransmitter that reduces neural excitability in the CNS.

Which part of the nervous system is responsible for the fight-or-flight response?

Somatic nervous system
Parasympathetic nervous system
Sympathetic nervous system
Central nervous system
3

The sympathetic nervous system prepares the body for emergency responses, such as increasing heart rate and blood flow.

Which part of the nervous system controls involuntary actions such as heartbeat and digestion?

Somatic nervous system
Central nervous system
Autonomic nervous system
Cerebral cortex
3

The autonomic nervous system regulates involuntary functions like heartbeat, respiration, and digestion.
