Does the arector pili muscles receive direct parasympathetic innervation?

Arector pili muscles get innervation from sympathetic out flow. But the neurotransmitter is acetylcholine. So functionally the nerve supply is parasympathetic.

Does the skin receive parasympathetic innervation?
Skin structures get innervation from sympathetic out flow. But the neurotransmitter is acetylcholine. So functionally the nerve supply is parasympathetic.
Which target tissues does not receive dual innervation?
most blood vessels
What organs does not receive parasympathetic input?
Skin Adrenal medulla
Are most innervated blood vessels receive only sympathetic nerve fibers?
Most of the viscera get nerve supply from both sympathetic and parasympathetic systems.
Which cranial nerves innervate salivary glands?
Parasympathetic innervation to the salivary glands is carried via cranial nerves. The parotid gland receives its parasympathetic input from the glossopharyngeal nerve (CN IX) via the otic ganglion, while the submandibular and sublingual glands receive their parasympathetic input from the facial nerve (CN VII) via the submandibular ganglion. These nerves release acetylcholine and substance P, which activate the IP3 and DAG pathways respectively.Direct sympathetic innervation of the salivary glands takes place via preganglionic nerves in the thoracic segments T1-T3 which synapse in the superior cervical ganglion with postganglionic neurons that release norepinephrine, which is then received by β-adrenergic receptors on the acinar and ductal cells of the salivary glands, leading to an increase in cyclic adenosine monophosphate (cAMP) levels and the corresponding increase of saliva secretion. Note that in this regard both parasympathetic and sympathetic stimuli result in an increase in salivary gland secretions.[3] The sympathetic nervous system also affects salivary gland secretions indirectly by innervating the blood vessels that supply the glands.

What is Dual innervation in terms of autonomic nervous system?
DUAL INNERVATION: One organ can receive impulses from both sympathetic and parasympathetic motor neurons (dual innervation); one division increases activity of organ, other division decreases activity of organ. While some organs are innervated by just one division, most vital organs receive dual innervation which means they receive instructions from both the sympathetic and parasympathetic divisions.
How can sympathetic and parasympathetic fibers exert antagonistic effects?
Sympathetic fibers convey impulses that stimulate our "fight or flight" response. Parasympathetic are just the opposite, you might say they are for "rest and digest". They are both firing at the same time but depending on your environment and emotional state, one will dominate over the other. Sympathetic and parasympathetic fibers release different neurotransmitters, which bind to different receptors. Three structures that receive sympathetic innervation are the adrenal glands, arrector pilli muscles, and sweat glands.
Does single innervation control heart rate?
