Nicotinic N  ANS ganglia
nicotinic M  neuromuscular end plate (M for muscle)

+
+
Mechanisms: they act on Na -K ion channels  depolarize and
evoke action potential

Adrenergic Receptors

 England  alpha 1 in effector tissues

 Never  alpha 2 in Nerve endings
and smooth muscles

 Have  beta 1 in heart

 Some  beta 2 in smooth muscles

 Apology beta 3 in adipose tissue

Dopamine D1 receptor in renal vascular smooth muscles

Mechanisms:

First alpha 1  increases IP3 DAG (like M 1)

Second alpha 2  decreases cAMP (like M 2)

Rest betas and dopamine receptors all increase cAMP

Adrenergic transmission
