A

Nucleus interpositus.

19
Q

The Cerebellum receives Information about the skin and Superficial fascia through which tract?

A

The Anterior Spinocerebellar tract

20
Q

Where is the Inferior Cerebellar Peduncle formed?

A

It is formed on the posterolateral aspect of the upper half of the medulla oblongata.

21

A

Inferior cerebellar peduncles

23
Q
A
24
Q

Which tract is known as the Double crosser?

A

The Anterior Spinocerebelllar tract

25

A

Medulloblastoma

26
Q

Which nucleus of the Thalamus receives neuronal input from Cerebellum?

A

The Ventral Lateral nucleus

27
Q

Where does the Ventral anterior thalamus receives its input from?

A

Basal Ganglia

28
Q

Where does the deep cerebellar nucleus receives its afferents from?

A

+ Inhibitory axons from Purkinje cells

+ Excitatory axons that are branches of afferent climbing and mossy
fibers passing to cortex

29
Q

What substance are used by Purkinje cells?

A

GABA

Q

Which nucleus is the Inferiorly displaced Pontine nuclei?

A

Arcuate nucleus

32
Q

What are the three functional areas of the Cerebellum?

A

+ Cortex of vermis influences movements of long axis of body (neck, shoulders, thorax, abdomen, hips)

+ Intermediate zone (lateral to vermis): control muscles of distal parts of limbs (especially hands and feet)

+ Lateral zone of each cerebellar hemisphere: planning of sequential movements of entire body and conscious assessment of movement errors.

33
Q

A
  • Intrinsic Fibres
  • Afferent Fibres
  • Efferent Fibres
34
Q

Which fibres of the cerebellum do not leave cerebellum but connect different areas of it
(e.g., connection of 2 cerebellar hemispheres together, or vermis with cerebellar cortex on same side) ?

A

Intrinsic fibres

35
Q

Fill in the blanks. “ Afferent fibres enter the cerebellum through _________ &___________.”

A

Middle & Inferior peduncles

36

Q

Where does the Deep Cerebellar nuclei receive afferent information from?

A
  • Inhibitory axons from Purkinje cells.
  • Excitatory axons that are branches of afferent climbing and mossy fibers passing to cortex.
