NeuroAnatomy Revision Flashcards
Location of the longitudinal fissure?
Separates the right and left cerebral hemispheres
Which fissure separates the cerebrum from the cerebellum?
Transverse fissure
Which lobe is involved in complex learning?
Frontal
Which lobe is involved in language acquisition?
Parietal
Which lobe is involved in processing of visual information?
Occipital
Which lobe is involved in understanding of written word?
Occipital lobe
Which lobe is involved in processing of information associated with hearing and equilibrium?
Temporal lobe
Which sulcus separates the frontal from parietal lobe?
Central
Which sulcus separates the parietal and occipital lobes?
Parieto-occipital sulcus
What does the lateral sulcus separate?
Separates the frontal and parietal lobes from the temporal lobes
Location of the insula?
Region of the cerebrum deep within the lateral sulcus
Function of the insula?
Processes information associated with hearing and equilibrium (is part of temporal lobe)
What is the corpus callosum?
Major bridge of white fibres that connect the two hemispheres of the cerebrum
Location of fornix? Function?
Bridge of white matter inferior to the corpus callosum; links regions of the limbic system (emotional brain) together
Location of the anterior commissure? Function?
Bridge of white fibres found near the anterior tip of the corpus callosum; connects the two hemispheres of the cerebrum
Function of the caudate nucleus?
Basal nucleus; initiates voluntary movements and coordinates slow skeletal muscle contractions (e.g. posture and balance).
Location of the caudate nucleus? Shape?
- There are two – one on each side – sitting astride the thalamus and next to the lateral ventricles (below the cerebral cortex).
- C-shaped structure with head, body and tail.
overall function of basal nuclei?
The “basal ganglia” refers to a group of subcortical nuclei within the brain responsible primarily for motor control, as well as other roles such as motor learning, executive functions, emotional behaviours, and play an important role in reward and reinforcement, addictive behaviours and habit formation.
View of putamen and globus pallidus
What is putamen + globus pallidus known as?
Lentiform nucleus
What structure composes 80% of the diencephalon?
Thalamus
Function of the thalamus?
Major relay point and processing centre for sensory impulses
