Does parasympathetic have postganglionic axons secrete norepinephrine?
No, parasympathetic postganglionic axons secrete the neurotransmitter acetylcholine, not norepinephrine. Norepinephrine is the primary neurotransmitter used by postganglionic neurons of the sympathetic nervous system.
Which autonomic neurons release norepinephrine as a neurotransmitte?
Sympathetic postganglionic neurons release norepinephrine,
Does parasympathetic nerves secrete norepinephrine?
No. They secrete acetylcholine only.
What do cholinergic neurons secrete?
Cholinergic neurons secrete acetylcholine.
Does the sympathetic or parasympathetic secrete norepinephrine?
Sympathetic
Does the Zona fasciculata in the adrenal gland secrete norepinephrine?
No
What are the two neurotransmitters that axon terminals of autonomic neurons release?
The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
All of these neurons release acetylcholine as a neurotransmitter except?
specific cardiac and smooth muscle fibers
What is neurotransmitter of the sympathetic nervous system?
acytelcholine in pre-ganglionic neurons, norepinephrine in most post-ganglionic neurons.
What endocrine glands secrete norepinephrine?
None, nerve endings aren't endocrine glands, are they?
What organ secretes the epinephrine and norepinephrine?
Adrenal gland, specifically its inner cortex.
What is the substance used by motor neurons to transmit stimuli to skeletal muscle?
