The cubital fossa, antecubital fossa, chelidon, or inside of elbow is the area on the anterior side of the upper part between the arm and forearm of a human or other hominid animals. It lies anteriorly to the elbow (antecubital) (Latin cubitus) when in standard anatomical position. The cubital fossa is a triangular area having three borders. [1]
The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. [1] The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus.
In anatomy, a fossa (/ ... Cubital fossa (a.k.a. Antecubital fossa or chelidon) Olecranon fossa; In the lower limb: Fossa ovalis (thigh) Trochanteric fossa;
At the cubital fossa, this nerve is deep to the pronator teres muscle and is the most medial structure in the fossa. The nerve passes into the forearm . The ulnar nerve , origin C8-T1, is a continuation of the medial cord of the brachial plexus .
In human anatomy, the median cubital vein (or median basilic vein) is a superficial vein of the arm on the anterior aspect of the elbow. It classically shunts blood from the cephalic to the basilic vein at the roof of the cubital fossa. It is typically the most prominent superficial vein in the human body, and is visible when all other veins ...
Cubital relates to the cubit or ulna and may refer to: Cubital fossa, the triangular area on the anterior view of the elbow joint of the arm; Cubital index, the ratio of two of the wing vein segments of honeybees; Cubital tunnel, channel which allows the Ulnar nerve (commonly known as the "funny bone") to travel over the elbow
The bicipital aponeurosis is superficial to the brachial artery and the median nerve, but deep to the median cubital vein. This protection is important during venipuncture (taking blood). It is one structure that has to be incised during fasciotomy in the treatment of acute compartment syndrome of the forearm and elbow region.
The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle.It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow.
