, Symp. vs Parasym. nerves
A DRUG can act via:
- CNS (centers),
- Ganglia (non-specific),
- Neuron (neuronal events),
- Receptor (receptor events).
,SYMPATHETIC DIVISION
, ADRENERGIC RECEPTORS
Def. : Adrenoceptors are membrane-bound receptors coupled with G
proteins, specific to adrenaline, noradrenaline & their antagonists.
Location: - CNS (central),
- Nerve endings (presynaptic),
- Effector organs (postsynaptic).
