Brain anatomy Flashcards
What does the brain stem consist of?
The Medulla, Pons, Cerebellum and Reticular Formation
Sulci
The ‘dips’ in the brain’s surface
Gyri
The ‘bumps’ in the brain’s surface
Rhombencephalon
Brain stem
Mesencephalon
Mid Brain; contains tegmentum and tectum
Diencephalon
Between Brain; contains thalamus and hypothalamus
Telencephalon
Endbrain
Tectum
Contains superior and inferior colliculi
Superior colliculi
Visual processing, orientation
Inferior colliculi
Auditory processing, orientation
Thalamus
Acts as a relay station for information destined for the cerebral cortex
Hypothalamus
Controls autonomic and endocrine systems; coordinates homeostasis. Interface between conscious thought and autonomic process.
The Limbic (Border) System consists of:
Cingulate Gyrus, which covers the Corpus Callosum, which is above the Fornix, which is above the Amygdala and Hippocampus, all around the Hypothalamus
The Basal Ganglia consists of;
The Caudate Nucleus, Putamen and Globus Pallidus
The Basal Ganglia consists of;
The Caudate Nucleus, Putamen and Globus Pallidus
What does the Basal Ganglia do?
Appears to be involved in the coordination of motor activity (Parkinson’s affects the Basal Ganglia)
Six layers of grey matter on top of white matter is called
The Neocortex
What is immediately superior to (on top of) the spinal cord head?
The Ventral Tegmental System (the bit between the pons and the hypothalamus)
Association areas
Areas of the brain that are involved in the integration of many types of information
Association areas
Areas of the brain that are involved in the integration of many types of information
Visual processing takes place in
The Occipital Lobe
The Primary Motor Cortex is located
In the Frontal Lobe
The Primary Motor Cortex is located
In the Frontal Lobe
The origin of most NA neurons in the brain (Noradrenaline)
Locus Ceruleus
The origin of most 5-HT (seretonin) neurons in the brain
The Raphe Nuclei
Origin of most DA (dopamine) neurons in the brain
Ventral Tegmental Area (Substantia Nigra)
Origin of most DA (dopamine) neurons in the brain
Ventral Tegmental Area (Substantia Nigra)
What processing occurs in the Cerebellum?
Coordination of and learning of movement
Function of Frontal Lobe
Motor, Planning
Parietal Lobe
Bodily Sensations
Temporal Lobe
Hearing, Visual
Occipital
Vision
The hemispheres are connected via
Corpus Callosum and Anterior Commisure and Massa Intermedia
