Most common transmitter substances found in motor and sensory NANC fibers nerve endings are
[A] substance P
[B] Purines
[C] Nitric oxide synthase
[D] Peptides
NANC fibers
NONADRENERGIC NONCHOLINERGIC NEURAL CONTROL
- Autonomic effector tissues – gut, airways, bladder
- Autonomic effector tissues contain nerve fibers that do not show the histochemical characteristics of either cholinergic or adrenergic
fibers. - Both motor and sensory NANC fibers are present.
- Peptides are the most common transmitter substances found in these nerve endings
- Other substances found in these nerve endings – nitric oxide synthase and purines
