Lecture 8- Neuroanatomy Flashcards
The fluid filling the brain’s ventricles is called
cerebrospinal fluid
The lateral dividing line between the frontal and temporal lobes is called the:
sylvian fissure
The dips or folds in the brain are called
Sulci
The cerebral cortex consists of how many main cortical layers?
6
The x, y, z coordinates that are used to define regions in the brain refer to the position relative to the
anterior commissure
A brain slice along the horizontal plane is commonly referred to as a/an
Axial section
Which region literally means “little brain” and, if extensively damaged, can lead to deficits in motor coordination?
cerebellum
The calcarine sulcus is in the
occipital lobe
CNS
Brain Spinal cord
PNS
Somatic nervous system Autonomic nervous system
Autonomic nervous system
Sympathetic nervous system Parasympathetic nervous system
Sympathetic nervous system is…
excitatory
Parasympathetic nervous system is…
inhibitory
What divides the frontal and parietal lobes?
central sulcus
what divides the parietal and occipital lobes?
parieto-occipital sulcus
The highest frontal gyrus is called?
Superior frontal gyrus
Name da Brain!
If i were to slice your head from ear to ear, what would this be called?
Coronal / Frontal
If i were to slice your brain between the hemispheres, from nasion to inion?
Sagittal
Where is the orbital gyri?
On the medial surface of the brain, surrounding the eyes.
What is the basal ganglia made up of?
Caudate, Putamen, Globus pallidus
Where is the internal capuse and what does it transfer?
White matter tract in the inferomedial part of each hemisphere. It carries information past the basal ganglia, separating the caudate nucleus and thalamus from the putamen and globus palliuds. It carries motor information from the PMC to the lower motor neurons in the spinal cord.
What is the association tract?
Carries information within a hemisphere
What is the commisure tract?
Carris info between hemispheres
