Most of these are cancers of the lymphoid tissues (leukemias and lymphomas), but one fifth of the cancers occur in the stomach, brain, ovary, skin, liver, larynx, parotid gland, and breast.
In most cases, the first sign of mumps is a swelling in the parotid glands; occasionally, mumps may begin with a slight fever, headache, and malaise before the swelling appears.
From the stylomastoid foramen, the nerve enters the parotid gland and divides into an estimated 7,000 nerve fibers that control a wide range of facial and neck activity.
The salivary glands are also called the parotid glands; therefore, mumps is sometimes referred to as an inflammation of the parotid glands (epidemic parotitis).
The doctor will take the child's temperature, gently palpate (touch) the skin over the parotid glands, and look inside the child's mouth.
Sometimes only one of the parotid glands is affected, but both may be inflamed at the same time or one after the other.
The poison is secreted in modified upper labial glands, or in a pair of large glands which are the homologues of the parotid salivary glands of other animals.
These changes are found in senile wasting, in metaplasia of cartilage, in many tumours, especially mixed growths of the parotid gland and testicle, and in various inflammatory granulation ulcers.
Of the salivary glands the parotid is by far the largest, elongated in the vertical direction, and narrower in the middle than at either end.
Salivary glands, of which the most constant are the parotid and the submaxillary, are always present in terrestrial mammals.
