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

Pregunta 2

Pregunta
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]
Respuesta
  • tentorium cerebelli

Pregunta 3

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

Pregunta 4

Pregunta
The area highlighted in blue is known as the Cerebellar ... ?
Respuesta
  • Vermis

Pregunta 5

Pregunta
The Arbor Vitae refers the the cerebellar grey matter.
Respuesta
  • True
  • False

Pregunta 6

Pregunta
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
Respuesta
  • Molecular
  • Purkinje Cell
  • Granular Cell

Pregunta 7

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

Pregunta 8

Pregunta
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.
Respuesta
  • Inhibitory
  • Excitatory

Pregunta 9

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

Pregunta 10

Pregunta
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?)
Respuesta
  • Thalamus

Pregunta 11

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

Pregunta 12

Pregunta
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.
Respuesta
  • Putamen
  • Globus Pallidus

Pregunta 13

Pregunta
Identify the structures on the diagram below.
Respuesta
  • Putamen
  • Globus Pallidus
  • Caudate Nucleus
  • Internal Capsule

Pregunta 14

Pregunta
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]
Respuesta
  • Substantia Nigra

Pregunta 15

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

Pregunta 16

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

Pregunta 17

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

Pregunta 18

Pregunta
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.
Respuesta
  • black
  • white
  • grey
  • purple
  • midbrain
  • pons
  • medulla
  • cerebral cortex

Respuesta
  • Hypokinesia
  • Hemianopia
  • Aphasia
  • Dementia
