Neural Control and Coordination
Test 6

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following is the main function of the neural system?

Regulation of body temperature
Coordination and integration of bodily functions
Production of hormones
Blood circulation
2

The neural system is responsible for coordinating and integrating various functions in the body, ensuring proper homeostasis.

Which of the following is a structural and functional unit of the neural system?

Neuron
Axon
Synapse
Dendrite
1

A neuron is the structural and functional unit of the neural system responsible for transmitting nerve impulses.

Which of the following statements about the sodium-potassium pump is incorrect?

It helps maintain the resting membrane potential of neurons.
It pumps sodium (Na⁺) out of the neuron and potassium (K⁺) into the neuron.
It requires ATP to function.
It allows sodium and potassium ions to move freely across the membrane.
4

The sodium-potassium pump actively transports ions using ATP, preventing free movement across the membrane.

Which of the following statements about the cerebellum is correct?

It coordinates voluntary movements and maintains balance.
It controls heart rate and digestion.
It is responsible for memory and intelligence.
It is part of the brainstem.
1

The cerebellum is responsible for coordinating voluntary movements and maintaining balance and posture.

Which of the following statements about the parasympathetic nervous system is correct?

It promotes the "fight or flight" response.
It increases digestion and decreases heart rate.
It dilates the pupils and increases blood pressure.
It only affects voluntary muscles.
2

The parasympathetic nervous system promotes the "rest and digest" response, slowing the heart rate and increasing digestion.

Which of the following statements about the autonomic nervous system is correct?

It controls involuntary functions like heart rate and digestion.
It is responsible for voluntary muscle movements.
It does not regulate glandular activity.
It consists only of motor neurons.
1

The autonomic nervous system (ANS) controls involuntary functions such as heart rate, digestion, and glandular secretion.

Which part of the brain is responsible for controlling voluntary movements?

Cerebellum
Thalamus
Cerebrum
Medulla oblongata
3

The cerebrum contains motor areas that control voluntary movements.

Which neurotransmitter is commonly involved in transmitting nerve impulses across synapses?

Insulin
Acetylcholine
Adrenaline
Thyroxine
2

Acetylcholine is a key neurotransmitter involved in the transmission of impulses across chemical synapses.

What is the function of the myelin sheath around a neuron?

To slow down nerve impulse conduction
To provide energy to neurons
To insulate the axon and speed up impulse conduction
To produce neurotransmitters
3

The myelin sheath insulates the axon, allowing nerve impulses to travel more quickly.

Which of the following is NOT a component of a neuron?

Axon
Dendrites
Synaptic cleft
Nissl’s granules
3

The synaptic cleft is the space between two neurons, not a component of a neuron itself.
