n.

The space bounded by the bones of the pelvis and pelvic girdle.

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.

oral cavity

the cavity of the mouth, made up of a vestibule and oral cavity proper.

pelvic cavity

the space within the walls of the pelvis.

pericardial cavity

the potential space between the epicardium and the parietal layer of the serous pericardium.

peritoneal cavity

the potential space between the parietal and the visceral peritoneum.

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.

uterine cavity

the space within the uterus communicating on either side with the uterine tubes and caudally with the vagina.

pelvic abscess

commonest in horses as a result of a rectal tear during a manual examination. The tear is only mucosa deep and the infection is deposited in the pelvic fascia where an abscess develops. This has the potential to erode into the peritoneal cavity. The syndrome begins as a toxemia and fever caused by the local abscess but a common sequel is the abrupt appearance of severe abdominal pain and toxemic shock.

pelvic bone

os coxae, comprising the ilium, ischium and pubis. See also Table 10.

pelvic canal

the canal from the pelvic inlet to the pelvic outlet.

pelvic cavity

the space bounded by the bones of the pelvis.

pelvic girdle

the bony ring formed by the pair of hip bones fused at the symphysis and their firm articulation with the sacrum, and in some species one or two coccygeal vertebrae.

pelvic inlet

the cranial opening of the pelvis.

pelvic intestinal hernia

see pelvic hernia.

pelvic ligaments

include the dorsal sacroiliac, the sacrotuberal and the iliolumbar ligaments.

pelvic limb

the hindlimb.

pelvic nerve

see Table 14.

pelvic organs

includes reproductive organs, urinary bladder, ureter, rectum.

pelvic outlet

the caudal opening of the pelvis, guarded by the pelvic diaphragm.

pelvic plexus

the autonomic plexus that is distributed to the pelvic viscera that consists of the cranial vesical plexus, the middle genital plexus and the caudal hemorrhoidal plexus, located on the ventrolateral surface of the rectum. It innervates the urinary bladder, prostate, ductus deferens and cranial urethra. It is supplied by the hypogastric and pelvic splanchnic nerves.

pelvic splanchnic nerves

see nervi erigentes.

pelvic symphysiotomy

surgical separation of the symphysis in immature animals as an aid in dystocia due to maternal pelvic inadequacy.

pelvic urethra

that part of the urethra that passes through the pelvis.

pelvic viscera

includes urinary bladder and pelvic ureters and urethra, rectum, prostate, seminal vesicles, vas deferens and ampullae in males, and vagina cervix and uterus, possibly ovaries, in the female.
