The bullet entered from the front, grooved the under surface of the acromial end of the clavicle with increasing depth, and eventually perforated the posterior margin of the bone, raising the compact tissue in an angular manner.
Words are omitted that have ambiguous or technical meanings not expressible in lay language. acromial (acromion)
The bullet has passed obliquely beneath the acromial end, rising to perforate the posterior compact margin, and producing one of the diamond-shaped openings sometimes occurring in compact bone with the passage of bullets at a low rate of velocity.
The bullet entered 2-1/2 inches below the acromial end of the right clavicle and emerged over the 9th rib in the posterior axillary line.
The tense cords of the brachial plexus of nerves, F, Plate 8, which will be found, for the most part, ranging along the acromial border of the artery, are a much surer guide to the vessel.
_Entry_, 1 inch from the left axillary margin in the first intercostal space; _exit_, at the back of the right arm 1-1/2 inch below the acromial angle; both pleuræ were therefore crossed.
The thoracoacromial artery (a. thoracoacromialis; acromiothoracic artery; thoracic axis) is a short trunk, which arises from the forepart of the axillary artery, its origin being generally overlapped by the upper edge of the Pectoralis minor Projecting forward to the upper border of this muscle, it pierces the coracoclavicular fascia and divides into four branchespectoral, acromial, clavicular, and deltoid.
The deltoid (humeral) branch, often arising with the acromial, crosses over the Pectoralis minor and passes in the same groove as the cephalic vein, between the Pectoralis major and Deltoideus, and gives branches to both muscles.
The acromial branch runs lateralward over the coracoid process and under the Deltoideus, to which it gives branches; it then pierces that muscle and ends on the acromion in an arterial network formed by branches from the transverse scapular, thoracoacromial, and posterior humeral circumflex arteries.
Where there is only one epiphysis, the nutrient artery is directed toward the other end of the bone; as toward the acromial end of the clavicle, toward the distal ends of the metacarpal bone of the thumb and the metatarsal bone of the great toe, and toward the proximal ends of the other metacarpal and metatarsal bones.
