Brain Lab Flashcards
What are the 3 white matter tracts?
Association Fibre
Commissural Fibre
Projection Fibre
Association Fibre
Between gyri in the same hemisphere (arcuate fasciculus)
Commissural Fibre
Between hemispheres (corpus collosium)
Projection Fibre
Descending or Ascending Tract (internal capsule)
Corpus Callosum
white matter tract carrying info between hemispheres
Thalamus
relays almost all sensory input to cortex
Caudate Nucleus
planning the execution of movement, but also in learning, memory, reward, motivation, emotion, and romantic interaction
Third Ventricle
contains CSF
surrounds the intermediate mass
behind the thalamus
Calcarine Sulcus
Marks the region of the primary visual cortex
Recieves info from both eyes at the optic chiasm
What are the anterior and posterior primary visual cortex used for?
Anterior = peripheral
Posterior = central
Mammillary body
Olfactory reflexes
Smells + involuntary actions
Intermediate Mass
Joins to thalami together
Cingulate Gyrus
Part of the limbic system (emotions)
Longitudinal Fissure
Separates Hemispheres
Gyri
Folds
Sulci
Grooves
What are the 3 components of the BRAINSTEM?
Midbrain
Pons
Medulla
What are the 3 components of the HINDBRAIN?
Cerebellum
Pons
Medulla
Oculomotor Nerve
Controls movement of the eyes
Cerebral Peduncles
Thick white matter tracts that carry info between the cerebral cortex and the spinal cord + pons
Cerebral Aqueduct
Carries CSF from the 3rd ventricle to the 4th
Superior + Inferior Canicului
Superior = Sight
Inferior = Sound
Where is CSF secreted from?
Choroid Pleus
Fourth Ventricle
Contains CSF that goes to central canal before leaving to protect the meninges
Cerebellum
Autonomic muscle control
-Smooths movement + balance
Medulla
Centre for cardiovascular + respiratory systems
What fibres pass through the medulla?
Spinal Fibres (cortico)
What fibres synapse at the pons?
Cortico-pontine fibres
What separates the Frontal and Parietal Lobes?
Central Sulcus
What separates the Frontal and Temporal Lobes?
Lateral Fissure
also separates P & T
What separates the Parietal and Occipital Lobes?
Parieto-occipital sulcus
What separates the back part of the Temporal Lobe and the Occipital Lobe?
Pre-occipital Notch
What makes up the Basal Ganglia?
Putamen
Globus Pallidus
Caudate Nucleus
Substantia Nigra
Subthalamic Nucelus
