Definition of manubrium in English:



Anatomy Zoology
  • 1A handle-shaped projection or part, in particular.

    • ‘The retroarticular process of the articular persists only as the tiny manubrium which remains in contact with the tympanic membrane as it presumably did in Probainognathus.’
    • ‘Some twenty minutes after the accident the patient used a spoonlike earpick to remove a bony fragment from deep in his ear canal and we identified this as the malleus that had been fractured at its manubrium.’
    • ‘The lenticular process is substantially longer than the arm of the manubrium which connects the tympanum to the articular facet.’
    • ‘The manubrium sometimes extends to the insertion of the third costal cartilages.’
    1. 1.1The broad upper part of the sternum of mammals, with which the clavicles and first ribs articulate.
      • ‘All rhinolophoids have an ossified first costal cartilage fused to the manubrium and first rib.’
      • ‘This approach involves incising the skin and subcutaneous tissue overlying the sternum, sawing longitudinally through the manubrium, body, and xiphoid process of the sternum, and cutting into the pericardial sacs.’
      • ‘It's just possible to make out the Angle of Louis, the ridge in the middle of the sword-shaped breastbone where its immature plates, the manubrium and sternal body fused.’
      • ‘The right and left parts of the muscle are joined by a tendon that arises from the manubrium of the sternum.’
      • ‘The medial-caudal migration pathway forms the thymopharyngeal tract, which runs from the angle of the mandible to the manubrium of the sternum bilaterally.’
    2. 1.2The tube that bears the mouth of a coelenterate.


Mid 17th century (as a rare usage in the sense handle): from Latin, haft.
