Cubital Fossa2
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 *Median cubital vein In human anatomy, the median cubital vein (or median basilic vein) is a superficial vein of the upper limb. It lies in the cubital fossa superficial to the bicipital aponeurosis. It connects the cephalic vein and the basilic vein. It becomes promi ...

Cubit
The cubit is an ancient unit of length based on the distance from the elbow to the tip of the middle finger. It was primarily associated with the Sumerians, Egyptians, and Israelites. The term ''cubit'' is found in the Bible regarding Noah's Ark, Ark of the Covenant, Tabernacle, Solomon's Temple Solomon's Temple, also known as the First Temple (, , ), was the Temple in Jerusalem between the 10th century BC and . According to the Hebrew Bible, it was commissioned by Solomon in the United Kingdom of Israel before being inherited by th .... The ''common cubit'' was divided into 6 palms × 4 Finger (unit), fingers = 24 digit (unit), digits. ''Royal cubits'' added a palm for 7 palms × 4 fingers = 28 digits. These lengths typically ranged from , with an ancient Roman cubit being as long as . Cubits of various lengths were employed in many parts of the world in ancient history, antiquity, during the Middle Ages and as recently as Early modern Europe, early modern time ...

Ulna
The ulna (''pl''. ulnae or ulnas) is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. That is, the ulna is on the same side of the forearm as the little finger. It runs parallel to the radius, the other long bone in the forearm. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore, the radius is considered to be the larger of the two. Structure The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It is broader close to the elbow, and narrows as it approaches the wrist. Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a hinge joint with the trochlea of the humerus. There is ...

Cubital Fossa
The cubital fossa, chelidon, or elbow pit, is the triangular area on the anterior side of the upper limb between the arm and forearm of a human or other hominid animals. It lies anteriorly to the elbow (Latin ) when in standard anatomical position. Boundaries * superior (proximal) boundary – an imaginary horizontal line connecting the medial epicondyle of the humerus to the lateral epicondyle of the humerus * medial (ulnar) boundary – lateral border of pronator teres muscle originating from the medial epicondyle of the humerus. * lateral (radial) boundary – medial border of brachioradialis muscle originating from the lateral supraepicondylar ridge of the humerus. * apex – it is directed inferiorly, and is formed by the meeting point of the lateral and medial boundaries * superficial boundary (roof) – skin, superficial fascia containing the median cubital vein, the lateral cutaneous nerve of the forearm and the medial cutaneous nerve of the forearm, deep fascia reinforce ...

Cubital Index
Cubital index is the ratio of two of the wing vein segments of honeybees. The cubital index is used in morphology, the study of form and structure, one way to differentiate species and sub species of living organisms. The pattern of the veins of the fore wings is specific for each breed of bees. The cubital index is consistent for a given race of bee. It can be used to distinguish between similar populations of honeybees and to determine degrees of hybridization. Procedure To obtain reliable average results, at least 100 bee fore wings have to be analyzed. Measurements are taken under a dissecting microscope with a magnification of 10x to 20x.

The genus name ''Apis'' is Latin for "bee", and ''mellifera'' is the Latin for "honey-bearing" or "honey carrying" ... Comparative anatomy Beekeeping ...

Cubital Tunnel
The cubital tunnel is a space of the dorsal medial elbow which allows passage of the ulnar nerve around the elbow. It is bordered medially by the medial epicondyle of the humerus, laterally by the olecranon process of the ulna and the tendinous arch joining the humeral and ulnar heads of the flexor carpi ulnaris. The roof of the cubital tunnel is elastic and formed by a myofascial trilaminar retinaculum (also known as the epicondyloolecranon ligament or Osborne band). Chronic compression of this nerve is known as cubital tunnel syndrome, a form of repetitive strain injury akin to carpal tunnel syndrome (although the role of repetitive stress in causing carpal tunnel syndrome is controversial).
