|
What enzyme cleaves the ester bond? |
Acetylcholinestrase (in the synpatic cleft) |
|
|
What are the two types of cholinergic receptors? |
Nictonic & muscarinic receptors So..although they are both stimulated by ACE, muscarinic is a GPCR and nictonic is a ligand gated |
|
|
Where are cholinergic receptors found in the autonomic nervous system? (on both pre-ganglia and post ganglia nerves) |
In the parasympathetic branch ACH is released in the pre-ganglion, binds to nicotonic (fast moving) Then ACH is released again Binds onto muscarinic at effector organs (in the parasympathetic branch...e.g. the heart) |
|
|
Where does the parasympathetic nerves come out from the CNS? |
-from the medulary and sacrial |
|
|
What do all targets in the parasympathetic nervous system act on? |
Musacrinic acetycholine receptors |
|
|
What neurotransmitters are involved in the sympathetic nervous system? |
ACH in pre-ganglionic, Binds to nicotonic AP produced Releases noradrenaline onto adrenergic receptors |
|
|
What is another way the sympathetic nervous system can be activated? |
ACh binds to muscarinic receptors on the adrenal medulla-> this then released adrenaline into the blood stream, to act of adrenergic effector organs |
