Neuroanatomy Lecture III

What are the three lobes of the cerebellum called?

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]

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

The area highlighted in blue is known as the Cerebellar ... ?

The Arbor Vitae refers the the cerebellar grey matter.

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

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

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.

Purkinje cells inhibit Deep Cerebellar Nuclei via the production of the neurotransmitter ...

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?)

The main functions of the basal ganglia are to facilitate purposeful movements whilst inhibiting unwanted movements.

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.

Identify the structures on the diagram below.

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]

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

In which area of a nerve does saltatory conduction occur, allowing propagation of action potentials?

Infarct to which of the following white matter bands is most likely to cause damage to the structures of the brainstem?

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.

An insult to the Lentiform Nucleus of the Basal Ganglia is most likely to cause which of the following clinical features?
