12. Basal Ganglia & Cerebellum - Orman

1. Neostriatum (Striatum) = Caudate + Putamen

True

False

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.

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.

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

True

False

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.

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

True

False

4) Subthalamus (diencephalon'da) 5) Substantia nigra (Midbrain'de)

Explanation

4) Subthalamus (diencephalon'da) 5) Substantia nigra (Midbrain'de)

4. Is [your statement here] true or false?

True

False

The given answer is true because it directly corresponds to the question. The question asks whether the statement provided is true or false, and the answer states that it is true.

Explanation

The given answer is true because it directly corresponds to the question. The question asks whether the statement provided is true or false, and the answer states that it is true.

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

True

False

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.

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

True

False

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.

7. Caudate & Putamen are output nuclei of basal ganglia.

True

False

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

Explanation

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

8. Subthalamus is between thalamus & tectum of the midbrain.

True

False

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

Explanation

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