Test 5

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which part of the neuron contains Nissl’s granules?

Axon
Dendrites
Cell body
Synaptic knob
3

Nissl’s granules, which are involved in protein synthesis, are found in the cell body of a neuron.

Which structure of the brain is involved in maintaining homeostasis?

Thalamus
Hypothalamus
Cerebellum
Medulla oblongata
2

The hypothalamus regulates homeostasis, including temperature, hunger, thirst, and hormone secretion.

Which part of the brain is responsible for higher-order thinking, learning, and intelligence?

Cerebellum
Cerebrum
Hypothalamus
Medulla oblongata
2

The cerebrum is the largest part of the brain and is responsible for cognition, memory, and intelligence.

Which division of the autonomic nervous system is responsible for increasing heart rate during stress?

Sympathetic nervous system
Parasympathetic nervous system
Somatic nervous system
Central nervous system
1

The sympathetic nervous system prepares the body for the "fight-or-flight" response by increasing heart rate and other physiological changes.

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

The peripheral nervous system consists of cranial and spinal nerves.
The central nervous system includes only the spinal cord.
Neurons can function without action potentials.
Neuroglia are responsible for transmitting nerve impulses.
1

The peripheral nervous system (PNS) consists of cranial and spinal nerves, which connect the CNS to the rest of the body.

Which of the following statements about neurons is correct?

Neurons can conduct impulses but cannot divide.
Neurons can divide and regenerate under all conditions.
Neurons do not require energy to function.
Neurons lack cell bodies.
1

Neurons can conduct nerve impulses but have limited ability to regenerate or divide.

Which of the following statements about the brainstem is incorrect?

It consists of the midbrain, pons, and medulla oblongata.
It controls involuntary actions like breathing and heart rate.
It is involved in higher cognitive functions like memory and reasoning.
It connects the brain to the spinal cord.
3

The brainstem regulates involuntary functions but does not control higher cognitive functions, which are managed by the cerebrum.

Which of the following statements about neurotransmitters is correct?

Neurotransmitters are chemical messengers that transmit signals across synapses.
Neurotransmitters are only released by sensory neurons.
Neurotransmitters are always excitatory.
Neurotransmitters pass through the synapse without binding to receptors.
1

Neurotransmitters are chemical messengers that transmit signals from one neuron to another across synapses.

Which type of synapse involves direct electrical communication between neurons?

Chemical synapse
Electrical synapse
Neurotransmitter synapse
Somatic synapse
2

Electrical synapses allow direct passage of ions and signals between neurons through gap junctions, enabling faster communication than chemical synapses.

Which of the following is a part of the limbic system and is involved in emotions and memory?

Hypothalamus
Medulla oblongata
Amygdala
Cerebellum
3

The amygdala is part of the limbic system and plays a key role in emotions, memory, and decision-making.
