    • ‘We took blood from the radial artery and the median cubital vein.’
    • ‘The ulnar nerve passes medial to the olecranon process and behind the medial epicondyle in the cubital tunnel.’
    • ‘The cubital fossa (anterior surface of the elbow) was palpated and the median cubital vein was readily located, facilitated by the Sailor repeatedly making a fist.’
    • ‘Placement of the cuff for brachial pressure measurement was approximately 3 cm above the cubital fossa.’
  • 2Entomology
    Of the cubitus.

    • ‘Hence, the basal displacement of the cubital veins of Archimelzira is convergent with Sciaridae and basal Cecidomyiidae like Catotricha Edwards, 1938.’
    • ‘The possibility of a close relationship with the Sciaridae is raised by the extreme cubital displacement towards the base of the wing in the New Jersey amber genus Archimelzira.’


Late Middle English: from Latin cubitalis, from cubitus ‘cubit’.
