Neuro Flashcards
Cerebellum function
Coordination and precision of motor Attention Language Fear Pleasure
Medulla function
Balance
Movement of vital systems eg resp
Pons function
Relay station between cortex/midbrain to cerebellum
Pattern eg walking
Tectum
Where and what
Dorsal , posterior of midbrain
Cerebral aqueduct to 4x colliculi
Superior- visual, inferior- auditory reflexes
Visuospatialauditory frequency maps
Tegmentum
Where
What
Ventral anterior if midbrain
Cerebral aqueduct to cerebral peduncles (connect to forebrain,, anterior tips =crus cerebri)
Red nucleus- input from motor cortex and cerebellum . Output to rubrospinal tract
Substantial nigra- parkinson
Nucleus acumbens- reward
Cerebral aqueduct surrounded by
Peri aqueductal grey
Reduces and modifies pain
Basilar supply
Cerebellum
Bit of back and bottom of cerebrum
Pons
Midbrain
Bilateral supply
Vertebral supply
Upper spinal cord
Inferior cerebellum
Medulla
Somatic vs autonomic synapse
Somatic no synapse after leaving cns
Autonomic synapse after cns — myelinated then unmyelinated
Sympathetic- In sympathetic chain
Para- nearer effector
Neurotransmitter and receptor type
- somatic at effector
- autonomic
- symp at synapse
- symp at effector
- parasymp at synapse
- parasymp at effector
Somatic- ach at muscarinic
Autonomic
Symp- ach at nicotinic
- noradrenaline at adrenergic
Parasymp- ach at nicotinic
- ach at muscarnic
Forebrain name
Prosencephalon
Forebrain parts x2
What is each made of
Telencephalon
- cerebrum, cerebral hemispheres
Diencephalon
- thalamus epithalamus hypothalamus
Midbrain
Mesencephalon
Midbrain made of
Tegmentum, cerebral peduncles
Hindbrain
Rhombencephalon
