  • Posterior lobe
  • Flocculonodular lobe
  • Floccularus lobe
  • Flocculondus lobe

Question 2

Question
The extension of dura mater that separates the cerebellum from the lower occipital lobe of the brain is called the [blank_start]tentorium cerebelli[blank_end]
Answer
  • tentorium cerebelli

Question 3

Question
The cerebellum is connected to the brainstem via 3 white matter tracts called [blank_start]Peduncles[blank_end]
Answer
  • Peduncles

Question 4

Question
The area highlighted in blue is known as the Cerebellar ... ?
Answer
  • Vermis

Question 5

Question
The Arbor Vitae refers the the cerebellar grey matter.
Answer
  • True
  • False

Question 6

Question
From superficial to deep, name the three layers of the cerebellum [blank_start]Molecular[blank_end] Layer [blank_start]Purkinje Cell[blank_end] Layer [blank_start]Granular Cell[blank_end] Layer
Answer
  • Molecular
  • Purkinje Cell
  • Granular Cell

Question 7

Question
The cerebellar grey matter which is deep to the white matter is referred to as the [blank_start]Deep Cerebellar Nuclei[blank_end]
Answer
  • Deep Cerebellar Nuclei

Question 8

Question
The main function of Purkinje cells are to send [blank_start]Inhibitory[blank_end] signals to the deep cerebellar nuclei in order to regulate the efferent motor signals being projected by the cerebellum.
Answer
  • Inhibitory
  • Excitatory

Question 9

Question
Purkinje cells inhibit Deep Cerebellar Nuclei via the production of the neurotransmitter ...
Answer
  • Glutamate
  • GABA
  • Glucose-1-Phosphate

Question 10

Question
After information has reached the Deep Cerebellar Nuclei, these areas of grey matter project efferent signals via axons which typically synapse in the [blank_start]Thalamus[blank_end] (which part of the brain?)
Answer
  • Thalamus

Question 11

Question
The main functions of the basal ganglia are to facilitate purposeful movements whilst inhibiting unwanted movements.
Answer
  • True
  • False

Question 12

Question
Within the Basal Ganglia, the Lenticular/Lentiform Nucleus is made up of the [blank_start]Putamen[blank_end] superficially and the [blank_start]Globus Pallidus[blank_end] deep.
Answer
  • Putamen
  • Globus Pallidus

Question 13

Question
Identify the structures on the diagram below.
Answer
  • Putamen
  • Globus Pallidus
  • Caudate Nucleus
  • Internal Capsule

Question 14

Question
As well as the caudate nucleus and the lentiform nucleus, the basal ganglia also consists of the subthalmic nucleus and the substantia nigra. Which of these areas is thought to be involved with Parkinson's Disease? [blank_start]Substantia Nigra[blank_end]
Answer
  • Substantia Nigra

Question 15

Question
The Cerebellum is a Contralateral brain. If there is a lesion in the left side, down the line this will affect right sided structures.
Answer
  • True
  • False

Question 16

Question
In which area of a nerve does saltatory conduction occur, allowing propagation of action potentials?
Answer
  • The Schwann Cells
  • The Axon
  • The Myelin Sheath
  • The Node of Ranvier

Question 17

Question
Infarct to which of the following white matter bands is most likely to cause damage to the structures of the brainstem?
Answer
  • The Corpus Callosum
  • The Internal Capsule
  • The Thalamus

Question 18

Question
The Substantia Nigra is a series of [blank_start]black[blank_end] bands in the [blank_start]midbrain[blank_end] that plays an important role in reward and movement systems.
Answer
  • black
  • white
  • grey
  • purple
  • midbrain
  • pons
  • medulla
  • cerebral cortex

Question 19

Question

Answer
  • Hypokinesia
  • Hemianopia
  • Aphasia
  • Dementia
