Exempel på hur man kan använda ANTRUM i en mening

• Somatostatin is secreted by delta cells at several locations in the digestive system, namely the pyloric antrum, the duodenum and the pancreatic islets.
• The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum).
• Gastrin is a linear peptide hormone produced by G cells of the duodenum and in the pyloric antrum of the stomach.
• The most common technique of a pancreaticoduodenectomy consists of the en bloc removal of the distal segment (antrum) of the stomach, the first and second portions of the duodenum, the head of the pancreas, the common bile duct, and the gallbladder.
• Maxillary antrum or antrum of Highmore, the maxillary sinus, a cavity in the maxilla and the largest of the paranasal sinuses.
• The mastoid antrum (tympanic antrum, antrum mastoideum, Valsalva's antrum) is an air space in the petrous portion of the temporal bone, communicating posteriorly with the mastoid cells and anteriorly with the epitympanic recess of the middle ear via the aditus to mastoid antrum (entrance to the mastoid antrum).
• Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.
• The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla.
• The endoderm lines the future auditory tube (pharyngotympanic Eustachian tube), middle ear, mastoid antrum, and inner layer of the tympanic membrane.
• The stylomastoid artery enters the stylomastoid foramen and supplies the tympanic cavity, the tympanic antrum and mastoid cells, and the semicircular canals.
• Between the posterior wall of the external acoustic meatus and the posterior root of the zygomatic process is the area called the suprameatal triangle (Macewen), or mastoid fossa, through which an instrument may be pushed into the tympanic antrum.
• The tympanic antrum is bounded above by a thin plate of bone, the tegmen tympani, which separates it from the middle fossa of the base of the skull, below by the mastoid process, laterally by the squama just below the temporal line, and medially by the lateral semicircular canal of the internal ear, which projects into its cavity.
• The surface of the subarcuate fossa is lined with dura mater and lodges the endolymphatic sac and duct, as well as a minute artery and vein; some veins from the mucosa of mastoid antrum enter the cranial cavity at the subarcuate fossa to drain at the superior petrosal sinus - they are remnants of larger subarcuate veins of childhood and represent a possible route of intracranial infectious spread.
• In the temporal bone, between the posterior wall of the external acoustic meatus and the posterior root of the zygomatic process is the area called the suprameatal triangle, suprameatal pit, mastoid fossa, foveola suprameatica, or Macewen's triangle, through which an instrument may be pushed into the mastoid antrum.
• Infections in the middle ear easily spread into the mastoid air cells through the aditus ad antrum, resulting in mastoiditis, a potentially dangerous and life-threatening condition.
• The Pyraustinae are characterised by atrophied spinula and venulae in the tympanal organs; a narrow fornix tympani; a longitudinal groove with androconial scales on the male mesothoracic tibiae; an often spinose antrum; and a sella (a medially directed clasper on the inside of the valvae), and an editum with modified setae on the male valvae.
• The pyramidal eminence is situated inferior to the aditus to mastoid antrum, immediately inferior to the oval window (fenestra vestibuli), and anterior to the vertical portion of the facial canal.
• The aditus to mastoid antrum (otomastoid foramen) is a large, irregular opening upon the posterior wall of the tympanic cavity by which the mastoid antrum (situated posteriorly) communicates with the epitympanic recess of the tympanic cavity (situated anteriorly).
• On Water's view radiograph, polypoid mass can be observed hanging from the floor into the maxillary antrum, classically known as teardrop sign, as it usually is in shape of a teardrop.
• As a follicle grows in size and the antrum develops, more layers of cumulus oophorus cells accumulate around the oocyte to aid in the acrosome reaction and sperm penetration into the oocyte.
