IOTA 2 & 3 Flashcards
Where does the spinal cord end at the brain?
At the Foramen Magnum - Cervicomedullary junction
What are components of the Brainste,?
Caudal: Medulla
Middle: Pons
Rostral: Midbrain
What separates the pons and the medulla?
Pontomedullary junction : cranial nerves 6,7,8
CN 6 exits - efferent
CN 7 enters and exits
CN 8 enters - afferent
What divides the midbrain and the pons?
Pontomesenphalic junction
What divides the midbrain and the duecephalon?
Midbrain-diencephalic junction
What structures make the diencephalon ?
Thalamus+ inter-thalamic adhesion (gateway to cortex)
Hypothalamus
What structures make the Cerebrum?
Cerebral hemisphere + Diencephalon
The cerebellum is inferior to?
Cerebrum
What are the 3parts of the brain?
Cerebrum = forebrain
Cerebellum
Brain stem
What are the 2 areas of the Forebrain (Cerebrum)
Diencephalon (deep in the brain) + Cerebral hemisphere
Components of Autonomic nervous systems?
Sympathetic nervous system
Parasympathetic nervous system
What are the components of the Cerebral hemisphere?
Cerebral cortex - surface cell bodies neurones
Basal nuclei - deep cell bodies
Hippocampus & amygdala - deep cell bodies : in medial-temporal lobe of brain
Function of hippocampus
Memory
What structure of the brain is responsible for emotions?
Amygdala
What a structures make the Limbic system?
Hippocampus + amygdala
This system is part of the Limbic lobe as this is connected to hippocampus and amygdala
