What is the effect of parasympathetic stimulation on this salivary glands?
Vanessaw877816
Sympathetic stimulation of your salivary glands suppresses the activity of the glands and salivation decreases. During parasympathetic stimulation you to salivate.

What type of glands are salivary glands?
Salivary glands are exocrine glands.
How many minor salivary glands are there?
There are about 600 to 1,000 minor salivary glands.
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 are intrinsic salivary glands?
Intrinsic salivary glands, located throughout the mouth, keep the mouth moist, while Extrinsic salivary glands secrete serous, enzyme-rich saliva in response to ingested food and the thought of food.
The functional classification of salivary glands is?
Merocrine glands
What is the effect of parasympathetic stimulation on the salivary glands?
The salivary glands work more. They produce more saliva. More enzymes are secreted. The saliva pass to the mouth cavity.
The effects of sympathetic and parasympathetic stimulation of the salivary glands are called?
complementary
Inhibition of parasympathetic nervous system activity causes the salivary glands to become?
hypoactive
Salivary glands?
The salivary glands in mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. Salivary glands can be classified as serous, mucousor seromucous (mixed).In serous secretions, the main type of protein secreted is alpha-amylase, an enzyme that breaks down starch into maltose and glucose, whereas in mucous secretions the main protein secreted is mucin, which acts as a lubricant.In humans, between 0.5 and 1.5 litres of saliva are produced every day. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.The fourth pair of salivary glands, the tubarial glands discovered in 2020 are named for their location, being positioned in front and over the torus tubarius. However, this finding from one study has to be confirmed.
What best demonstrates an example of cooperation of the parasympathetic and sympathetic nervous systems?
The best example of cooperative autonomic effects is seen in controls of the external genitalia. Parasympathetic stimulation causes vasodilation of blood vessels in the external genitalia, and is responsible for erection of the male penis or female clitoris during sexual excitement. Sympathetic stimulation then causes the ejaculation of semen by the penis or reflex contractions of the vagina during an orgasm.
What type of glands are salivary glands?
Salivary glands are exocrine glands.
What body part produces saliva?
The salivary glands in the mouth produce saliva.
How many minor salivary glands are there?
There are about 600 to 1,000 minor salivary glands.
Are The salivary glands located near the pancreas?
No. Salivary glands are close to the Pharynx.
Is salivary glands in human in pairs or single?
Humans have paired salivary glands.
What are the large pairs of salivary gland?
There are three big pairs of salivary glands in addition to many smaller ones. The parotid glands, submandibular glands and sublingual glands are the large, paired salivary glands.
