nosebleeds.
Stenson’s ducts
duct of the parotid salivary gland.
Thrush
A contagious disease caused by a fungus, Candida albicans, that occurs most often in infants and children,
characterized by small whitish eruptions on the mouth, throat, and tongue, and usually accompanied by fever, colic, and diarrhea.

Calor
heat; one of the cardinal signs of inflammation.
Dolor
any condition of physical pain, mental anguish, or suffering from heat. It is one of the four signs of inflammation.
Hyperthyroidism
a condition characterized by hyperactivity of the thyroid gland. The gland is usually enlarged, secreting greater than normal amounts of thyroid hormones, and the metabolic processes of the body are accelerated. Nervousness, exophthalmos, tremor, constant hunger, weight loss, fatigue, heat intolerance, palpitations, and diarrhea may develop. Antithyroid drugs, such as propylthiouracil or methimazole, are usually prescribed. Radioactive iodine may be prescribed in certain cases. Surgical ablation of the gland is sometimes necessary. Untreated hyperthyroidism may lead to death from cardiac failure
Macrocephaly
A condition, either congenital or acquired, in which the head is abnormally large; usually applied to an adult cranium with a capacity of over 1450 mL
Myxedema

Tic
Brief and intermittent involuntary movement or sound
Vertex
: the summit or top, especially the top of the head
Bruit
sound or murmur heard in auscultation, especially an abnormal one
Crepitus
(1) flatulence or the noisy discharge of fetid gas from the intestine through the anus. (2) a sound or feel that resembles the crackling noise heard when rubbing hair between the fingers or throwing salt on an open fire. Crepitus is associated with gas gangrene, rubbing of bone fragments, air in superficial tissues, or crackles of a consolidated area of the lung in pneumonia. (3) a clicking sound often heard in movement of joints, for example, in temporomandibular joint resulting from joint irregularities. Also called crepitation.
Goiter
A noncancerous enlargement of the thyroid gland, visible as a swelling at the front of the neck, that is often associated with iodine deficiency. May be associated with hyperthyroidism, hypothyroidism, or normal levels of thyroid function.
Hypothyroidism
a diminished activity of the thyroid gland with decreased secretion of thyroxin, resulting in lowered basal metabolic rate, lethargy, sleepiness, dysmenorrhea in females, and a tendency toward obesity. Occasionally there is accompanying gingival hyperplasia. The condition is called cretinism in children and myxedema in adults.
