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).
pelvic cavity the space within the walls of the pelvis.

peritoneal cavity the potential space between the parietal and the visceral peritoneum.
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.
