ANS Flashcards
ans divisions
sympathetic, parasympathetic and enteric
enteric is controlled via what fibers
sympathetic and parasympathetic
sympathetic pathway
Preganglion (ach) -> nicotinic arch receptor (ach) -> adrenargernic receptor (NE) or cholinergernic / muscarinic receptor (ach)
NE receptor
a1, a3, b1 and b2
parasym pathway
preganglion (ach) -> nicotinic receptor (ach) -> muscarinic receptor
parasym pathway
preganglion (ach) -> nicotinic receptor (ach) -> muscarinic receptor
parasym pathway
preganglion (ach) -> nicotinic receptor (ach) -> muscarinic receptor
Whats the b1 and b2 receptor for
B1 - heart rate
B2 - broncho dilation
How does adrenaline and noradrenaline enters the blood
Via adrenal medulla
What controls the ANS
Brain stem, forebrain, hypothalamus
What is b blocker used for
To prevent the binding of b1 receptor for hypertension patient
How to treat asthma
Using b2 binding drug to promote bronchodilation
Frontal lobe functions
Coordination, behaviour, memory
Prefrontal association area function
Planning and elaborate thoughts
Lesion at prefrontal ass. Area
Cant plan and change in behavior and personality
Parietal lobe function
Receive sensory info`
Temporal function
Receive info of hearing, tasting and smelling
Wernicke’s area function
Language interpretation
Broca’s area function
Speech production
Occipital lobe function
Receive visual info
How does wernicke’s and broca’s communicate
Via arcuate fasciculus
Hippocampus function
Memory
Anterograde amnesia
Cant make new memory
Retrograde amnesia
Cant retrieve old memory
What control sleep
Brain stem + nuclei (suprachiasmastic)
Melatonin is secreted via
Pineal gland
Nonrem is
No rapid eye movement - it is when we have the slow waves
What are the 4 stages of sleep
Drowsy, light sleep, moderate to deep sleep and deep sleep `
Narcolepsy
