cavity

1. a hollow or space, or a potentional space, within the body (e.g. abdominal cavity) or one of its organs (e.g. cranial cavity).

2. in teeth, the lesion produced by dental caries.

absorption c's

cavities in developing compact bone due to osteoclastic erosion, usually occurring in the areas laid down first.

amniotic cavity

the closed sac between the embryo and the amnion, containing the amniotic fluid.

cranial cavity

the space enclosed by the bones of the cranium.

dental cavity

1. the central space, often branched or multiple in compound teeth, of each tooth; carries the nerve and blood supplies to the teeth.

2. the defect caused by decay on a tooth surface. Called also caries.

glenoid cavity

a depression in the ventral angle of the scapula for articulation with the humerus.

infraglottic cavity

the space in the larynx caudal to the vocal folds; reflects the shape of the cricoid cartilage.

medullary (marrow) cavity

the cavity, containing marrow, in the diaphysis of a long bone; called also medullary canal.

nasal cavity

the proximal part of the respiratory tract, within the nose, bisected by the nasal septum and extending from the nares to the pharynx. Much of the cavity is occupied by the turbinate bones or conchae which also divide it into dorsal, medial and ventral meatuses. The common meatus is the narrow, vertical passage close to the nasal septum. The rostral end of the cavity just inside the nostril is the nasal vestibule, and the caudal part opening into the pharynx is the nasopharyngeal meatus.

pleural cavity

the potential space between the parietal and the visceral pleura.

pulp cavity

the pulp-filled central chamber in a tooth; called also dental cavity.

serous cavity

a celomic cavity, like that enclosed by the pericardium, peritoneum or pleura, not communicating with the outside of the body and lined with a serous membrane, i.e. one which secretes a serous fluid.

tension cavity

cavities of the lung in which the air pressure is greater than that of the atmosphere.

thoracic cavity

the body cavity situated between the neck and the diaphragm.

tympanic cavity

the cavity of the middle ear.

Patient discussion about Mouth (human).

Q. What is the treatment for tongue cancer? My Father in Law is 65 and has just been diagnosed with tongue cancer. What treatment will he be undergoing? What are his survival rates?

A. Treating tongue cancer will depend on the size of the cancer and whether or not it has spread to the lymph nodes in your neck. The best treatment for very small tongue cancers is surgery. Most very small cancers of the oral tongue can be quickly and successfully treated by surgical removal leaving behind little cosmetic or functional change. For larger tumours that have spread to the lymph nodes in the neck, you will most likely have a combination of surgery and radiotherapy.

Q. What are the effects of alcoholism on the oral cavity? I have to make a presentation on this topic, and I would like to know what are the main pathological effects of chronic alcoholism on the oral cavity, I know that it is a carcinogen, but it mainly acts as a promoter, is there any cancer that is caused by alcohol abuse?

A. alcohol can interact harmfully with several medications commonly used in dental treatment. Alcohol intensifies the depressant effect of barbituates and tranquilizers creating a higher risk of deep sedation and unconsciousness. Following treatment, the ability to drive may be impaired. Medications used to control high blood pressure and angina have a dilating effect on the blood vessels which is intensified by alcohol.

The result is a higher likelihood of low blood pressure and fainting. Even the action of aspirin is intensified by alcohol, causing excessive bleeding by disrupting clot formation
