Cubital Fossa - Contents

Contents

The cubital fossa contains four main vertical structures (from lateral to medial):

  • The radial nerve is in the vicinity of the cubital fossa, located between brachioradialis and brachialis muscles. It is often but not always considered part of the cubital fossa.
  • The biceps brachii tendon
  • The brachial artery. The artery usually bifurcates near the apex (inferior part) of the cubital fossa into the radial artery (superficial) and ulnar artery (deeper)
  • The median nerve

The ulnar nerve is also in the area, but is not in the cubital fossa; it occupies a groove on the posterior aspect of the medial epicondyle of the humerus.

Several veins are also in the area (for example, the median cubital vein, cephalic vein, and basilic vein) but these are usually considered superficial to the cubital fossa, and not part of its contents.

Famous quotes containing the word contents:

    “Such as boxed
    Their feelings properly, complete to tags
    A box for dark men and a box for Other
    Would often find the contents had been scrambled.”
    —Gwendolyn Brooks (b. 1917)

    “Yet to speak of the whole world as metaphor
    Is still to stick to the contents of the mind
    And the desire to believe in a metaphor.
    It is to stick to the nicer knowledge of
    Belief, that what it believes in is not true.”
    —Wallace Stevens (1879–1955)

    “If one reads a newspaper only for information, one does not learn the truth, not even the truth about the paper. The truth is that the newspaper is not a statement of contents but the contents themselves; and more than that, it is an instigator.”
    —Karl Kraus (1874–1936)
