Questions and Answers
  • 1. 

    There are 5 basal ganglia structures. The ones @ telencephalon are: 1) Caudate 2) Putamen 3) Globus pallidus.

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    4) Subthalamus (diencephalon'da) 5) Substantia nigra (Midbrain'de)

  • 2. 

    The output of the cerebellum is excitatory, while the basal ganglia are inhibitory.

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    The cerebellum is responsible for coordinating voluntary movements and maintaining balance. It sends excitatory signals to the motor cortex, enhancing the activity of the muscles involved in movement. On the other hand, the basal ganglia play a role in regulating movement by inhibiting certain motor pathways. Therefore, the statement that the output of the cerebellum is excitatory, while the basal ganglia are inhibitory is true.

    Lentiform nucleus  (Lenticular nucleus) = Putamen + Globus pallidus (GP)

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the lentiform nucleus, also known as the lenticular nucleus, is composed of two structures: the putamen and the globus pallidus (GP). These structures are located deep within the brain and play important roles in motor control and movement. The putamen is involved in motor planning and execution, while the globus pallidus helps regulate movement by inhibiting certain motor pathways. Therefore, it is correct to say that the lentiform nucleus is made up of the putamen and globus pallidus.

    Neostriatum (Striatum) = Caudate + Putamen

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the neostriatum, also known as the striatum, is indeed composed of two structures: the caudate nucleus and the putamen. These two structures are interconnected and together form the major input region of the basal ganglia.

  • 5. 

    Is [your statement here] true or false?

    • A. 

      True

    • B. 

      False

  • 6. 

    Subthalamus is between thalamus & tectum of the midbrain.

    • A. 

      True

    • B. 

      False

    Correct Answer
    B. False
    Explanation
    Tegmentum öndeki midbrain kismi. Tectum cerebral aqueduct arkasında sup. ve inf. collicus'larin meydana getirdigi kisim. Tegmentum-thalamus arasinda thalamus altindadir subthalamus.

    Caudate & Putamen are output nuclei of basal ganglia.

    • A. 

      True

    • B. 

      False

    Correct Answer
    B. False
    Explanation
    Basal ganglia'ya bilgi geliyorsa bu ikisine gelir. Giren bilgi anlaminda-input nuclei'dir. Output bilginin ciktigi cekirdekler.

    Rate this question:

  • 8. 

    Flocculonodular lobe is the oldest (evolutinarily) lobe of the three of the cerebellar lobes. Archicerebellum.

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    The flocculonodular lobe is considered the oldest (evolutionarily) lobe of the three cerebellar lobes. It is also known as the archicerebellum. This lobe is responsible for maintaining balance and coordinating eye movements. Its evolutionary significance lies in its role in basic motor functions, which are believed to have developed early in the evolution of vertebrates. Therefore, the statement "Flocculonodular lobe is the oldest (evolutionarily) lobe of the three cerebellar lobes" is true.
