What is the primary function of the limbic system?

  1. Processing sensory information

  2. Controlling motor functions

  3. Regulating emotions and behavior

  4. Storing memories


Correct Option: C
Explanation:

The limbic system is responsible for processing emotions, motivation, memory, and behavior.

Which of the following structures is NOT part of the limbic system?

  1. Amygdala

  2. Hippocampus

  3. Thalamus

  4. Hypothalamus


Correct Option: C
Explanation:

The thalamus is part of the diencephalon, not the limbic system.

What is the role of the amygdala in the limbic system?

  1. Processing fear and aggression

  2. Forming memories

  3. Regulating body temperature

  4. Controlling sleep-wake cycles


Correct Option: A
Explanation:

The amygdala is involved in processing emotions, particularly fear and aggression.

What is the function of the hippocampus in the limbic system?

  1. Processing sensory information

  2. Controlling motor functions

  3. Forming and consolidating memories

  4. Regulating emotions


Correct Option: C
Explanation:

The hippocampus is involved in the formation and consolidation of memories.

Which of the following hormones is NOT regulated by the hypothalamus?

  1. Oxytocin

  2. Vasopressin

  3. Epinephrine

  4. Cortisol


Correct Option: C
Explanation:

Epinephrine is regulated by the adrenal glands, not the hypothalamus.

What is the role of the hypothalamus in the limbic system?

  1. Regulating body temperature

  2. Controlling sleep-wake cycles

  3. Processing emotions

  4. Forming memories


Correct Option:
Explanation:

The hypothalamus is involved in regulating body temperature, controlling sleep-wake cycles, and releasing hormones.

Which of the following is NOT a component of the Papez circuit?

  1. Hippocampus

  2. Amygdala

  3. Mammillary bodies

  4. Thalamus


Correct Option: D
Explanation:

The Papez circuit is a neural pathway involved in emotion and memory. It consists of the hippocampus, amygdala, mammillary bodies, and cingulate gyrus, but not the thalamus.

What is the function of the cingulate gyrus in the limbic system?

  1. Processing sensory information

  2. Controlling motor functions

  3. Regulating emotions and attention

  4. Storing memories


Correct Option: C
Explanation:

The cingulate gyrus is involved in regulating emotions, attention, and decision-making.

Which of the following is NOT a neurotransmitter involved in the limbic system?

  1. Dopamine

  2. Serotonin

  3. Glutamate

  4. GABA


Correct Option: C
Explanation:

Glutamate is the primary excitatory neurotransmitter in the central nervous system, but it is not specifically involved in the limbic system.

What is the role of dopamine in the limbic system?

  1. Processing fear and aggression

  2. Forming memories

  3. Regulating motivation and reward

  4. Controlling sleep-wake cycles


Correct Option: C
Explanation:

Dopamine is involved in regulating motivation, reward, and pleasure.

Which of the following is NOT a disorder associated with the limbic system?

  1. Schizophrenia

  2. Depression

  3. Parkinson's disease

  4. Epilepsy


Correct Option: C
Explanation:

Parkinson's disease is a neurodegenerative disorder that affects the basal ganglia, not the limbic system.

What is the role of the limbic system in memory?

  1. Storing long-term memories

  2. Processing sensory information

  3. Controlling motor functions

  4. Regulating emotions


Correct Option: A
Explanation:

The limbic system is involved in the formation and consolidation of long-term memories.

Which of the following is NOT a structure involved in the limbic system?

  1. Fornix

  2. Habenula

  3. Thalamus

  4. Septum pellucidum


Correct Option: C
Explanation:

The thalamus is part of the diencephalon, not the limbic system.

What is the role of the habenula in the limbic system?

  1. Processing fear and aggression

  2. Forming memories

  3. Regulating reward and punishment

  4. Controlling sleep-wake cycles


Correct Option: C
Explanation:

The habenula is involved in regulating reward and punishment, as well as motivation and aversion.

Which of the following is NOT a function of the limbic system?

  1. Processing sensory information

  2. Controlling motor functions

  3. Regulating emotions and behavior

  4. Storing memories


Correct Option: A
Explanation:

The limbic system is not involved in processing sensory information. This is the function of the sensory cortex.
