The artery will then be felt pulsating, but hidden by the costo-coracoid membrane, which acts as its sheath.
Stage of Metatheria, or Marsupialia, are direct descendants of Prototheria; but they show higher development by the reduction of the coracoid bones and the interclavicle.

It arises above from the coracoid process, and thence passes downwards towards the internal surface of the humerus into which it is inserted, more or less high up, according to the species.
It arises above from a tubercle at the base of the coracoid process, which surmounts the glenoid cavity of the scapula.
Its coracoid process is represented by a peculiar bone--the coracoidean or coracoid bone--which we shall describe later on when we come to the study of the clavicle and of the anterior region of the shoulder (see p.
The coracoid process is represented by a small tubercle, slightly curved inwards; this tubercle is situated above the glenoid cavity, at the inferior part of the cervical border.
Furthermore, a bone named thecoracoid joins the scapula to the sternum; this bone, often fused with the scapula, where it contributes to the formation of the glenoid cavity, represents in birds the coracoid process of the human scapula.
Above this cavity, on the lower part of the cervical border, is situated a tubercle which reminds us of the coracoid process of the human scapula.
The coracoid bone, like the fourchette which it reinforces, offers to the wings a degree of support proportionate to the efforts developed by those limbs; for this reason it is thick and solid in birds of powerful flight.
The tubercle which represents the coracoid process is curved inwards more strongly than that of the dog, thus resembling more closely the appearance of this process in the human being.
In the place of the rabbit's coracoid process, is a coracoid bone (co.
The clavicles are also well developed, and vestiges of the precoracoid and of the sternal end of the coracoid are often found.
The coracoid is a short bone attached above to the scapula and below to the presternum; it forms a large part of the glenoid cavity.
Considerable remains of the sternal end of the coracoid are also found.
There is no precoracoid (epicoracoid) or interclavicle, and the coracoid is reduced to form a mere process of the scapula, not coming near the sternum.
The dorsal end is continuous with an area of unossified cartilage which separates the coracoid and scapula and forms part of the glenoid cavity.
The clavicles are very long and strong, and the scapula has a long spine and coracoid process.
Clavicles are well developed, and the scapula and coracoid are nearly at right angles to one another.
If the head of the humerus be dislocated forwards beneath L, Plate 11, the coracoid attachment of the pectoralis minor muscle, it must press out of their proper place and put tensely upon the stretch the axillary vessels and plexus of nerves.
Even in the undissected body the coracoid process may be felt as a fixed resisting point at that cellular interval between the clavicular attachments of the deltoid and great pectoral muscles.
F, Plate 16, usually marks, may take place at any part of the member between the bend of the elbow and the coracoid process in the axillary space.
It is equally evident, after a detailed comparison, that the single coracoid element of the Ganoids represents the three elements developed in the generalized Teleosts (Cyprinids, etc.
The element of the Dipnoan's shoulder-girdle, continuous downward from the scapula, and to which the coracoid is closely applied, may be named ectocoracoid.
The coracoid of Polypterids is also evidently homologous with the corresponding element in the other Ganoids, and the latter consequently must be also coracoid.
Having the form of a trapezoid; trapezoidal; as, the trapezoid ligament which connects the coracoid process and the clavicle.
Defn: The anterior part of the coracoid (often closely united with the clavicle) in the shoulder girdle of many reptiles and amphibians.
Defn: Situated under the coracoid process of the scapula; as, the subcoracoid dislocation of the humerus.
Defn: A process from the middle of the coracoid in some animals.
It is, however, probable that all species of the genus retained a tiny rudiment of wings in greatly dwindled scapulo-coracoid bones.
In some birds, the albatross, for example, the coracoid is short and stout, while in others extra bracing is obtained from the wishbone.
Obviously the greater the strain the greater the need of strengthening or bracing the coracoid to resist it, and there are in the shoulder girdle of a bird various devices looking towards this end.
Coracoid nearly as long as acromion, slender, a little curved upward, irregular and somewhat expanded at the end.
The coracoid is as long as the acromion, nearly straight and horizontal, but expanded at the end.
The part of the girdle lying dorsal to the articulation of the limb is termed scapular in the case of the pectoral limb, iliac in the case of the pelvic, while the ventral portions are known respectively as coracoid and ischio-pubic.
The coracoid is however a real vertebral element (hæmapophysis), and in monotremes, birds and reptiles it is in the adult a large and separate bone.
But there is no teleological reason why the coracoid process of the scapula should in all mammals develop from a separate centre.
In Amphibia the two halves of the shoulder girdle are each formed as a continuous plate, the ventral or coracoid part of which is forked, and is composed of a larger posterior and a smaller anterior bar-like process, united dorsally.
It forms a rod with a dorsal scapular and ventral coracoid process.
The scapulo-coracoid plate soon becomes cartilaginous, while at the same time the clavicular bar ossifies directly from the membranous state.
The coracoid process becomes in the course of development gradually reduced.
The coracoid process is however well developed in the Selachioid Ganoids, and the Siluroid Teleostei.
This process, known as the coracoid process, is held by Sabatier to be the praecoracoid; while this author also holds that the upper third of the glenoid cavity, which ossifies by a special nucleus, is the true coracoid.
It is formed by a fenestration of a primitively continuous cartilaginouscoracoid plate (Hoffmann).
A praecoracoid, partially separated from the coracoid by a space, is present in Struthio.
It is on all hands admitted that the scapulo-coracoid elements of the shoulder girdle are formed as a pair of cartilaginous plates, one on each side of the body.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "coracoid" in a variety of sentences. We hope that you will now be able to make sentences using this word.
