  • Bronchial respiration

    The sound of normal breathing as heard over the primary air passages in a healthy individual.  

  • Brudzinski’s reflex

    In cases of meningitis, when the patient’s head is flexed, it leads to flexion of the ankle, knee, and hip as well. Another way to conduct this test is by flexing one leg at the hip joint, which results in automatic flexion of the other leg.  

  • Brucellergen reaction

    A skin response caused by injecting antigens from Brucella bacteria into the skin layer, used to diagnose undulant fever.  

  • Bipolar pressure

    Pressure applied to both ends of a bone, occasionally employed to distinguish a bone fracture from mere contusions. This is because applying moderate force to both ends of the bone will elicit pain at the fracture site if one exists.  

  • Back-pressure effect

    The accumulation of blood in the venous system due to the heart’s inability to transfer blood from the venous system to the arterial system as rapidly as it is received.  

  • Bronchoscopic position

    The patient reclines horizontally with the head tilted backward to align the larynx and trachea in a straight line. This positioning allows for the insertion of the bronchoscope.  

  • Bronchial pneumonia

    Inflammation, frequently characterized by patchy distribution, that has extended from infected bronchi to the lung tissue. Also known as bronchopneumonia.  

  • Black plague

    The disease that ravaged Europe during the 14th century, known as the “plague,” earned its name due to the frequent occurrence of hemorrhages.  

  • Buccal occlusion

    The orientation of a premolar or molar tooth that is situated beyond the normal alignment of occlusion.
