marrow cavity (medullary cavity) the cavity that contains bone marrow in the diaphysis of a long bone; called also medullary canal.
nasal cavity the proximal portion of the passages of the respiratory system, extending from the nares to the pharynx; it is divided into left and right halves by the nasal septum and is separated from the oral cavity by the hard palate.
oral cavity the cavity of the mouth, bounded by the jaw bones and associated structures (muscles and mucosa).

pleural cavity the potential space between the two layers of pleura.
pulp cavity the pulp-filled central chamber in the crown of a tooth.
cavity of septum pellucidum the median cleft between the two laminae of the septum pellucidum. Called also pseudocele, pseudocoele, and fifth ventricle.
serous cavity a coelomic 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 portion of the ventral body cavity situated between the neck and the diaphragm; it contains the pleural cavity.
tympanic cavity the major portion of the middle ear, consisting of a narrow air-filled cavity in the temporal bone that contains the auditory ossicles and communicates with the mastoid air cells and the mastoid antrum by means of the aditus and the nasopharynx by means of the auditory tube. The middle ear and the tympanic cavity were formerly regarded as being synonymous.
uterine cavity the flattened space within the uterus communicating proximally on either side with the fallopian tubes and below with the vagina.
