When the platelets bind to a clot, they release serotonin, where it serves as a vasoconstrictor and helps to regulate hemostasis and blood clotting. Serotonin also is a growth factor for some types of cells, which may give it a role in wound healing.erotonin's presence in insect venoms and plant spines serves to cause pain, which is a side-effect of serotonin injection.

The salivary glands are made up of a number of different types of cells. The type of cancer you have is named after the type of cell the cancer started in. This means that your doctor will tell you which salivary gland your cancer started in â the parotid, submandibular, sublingual or minor salivary glands.
There are 3 pairs of major salivary glands: 1  Parotid glands: These are the largest salivary glands and are found in front of and just below each ear. 2  Sublingual glands: These glands are found under the tongue in the floor of the mouth. 3  Submandibular glands: These glands are found below the jawbone...alivary gland cancer is a rare disease in which malignant (cancer) cells form in the tissues of the salivary glands. The salivary glands make saliva and release it into the mouth. Saliva has enzymes that help digest food and antibodies that help protect against infections of the mouth and throat.
