Thus, in none of the measurements did the humerus exceed the ulna two inches, which in the Caucasian variety is the lowest number. In all the black races the arm is longer in proportion to the stature than in the white.
Struthers, Dr., on the occurrence of the supra-condyloid foramen in the humerus of man. Sturnella ludoviciana, pugnacity of the male. Sturnus vulgaris. Sub-species. Suffering, in strangers, indifference of savages to. Suicide, formerly not regarded as a crime; rarely practised among the lowest savages. Suidae, stripes of the young.
The broken shaft with its blade deep in the thorax had completely severed the head of his humerus, cut two ribs, and killed him by hemorrhage from the pulmonary arteries. Half-grown as he was, he would have made an ugly antagonist for any man. His mother, a fine mature lady of the old school, showed by her teeth and other lineaments her age and respectability.
Cook speaks of a female child born of Indian parents, the fourth birth of a mother twenty-six years old. The child weighed 5 1/2 pounds; the circumference of the head was 14 inches and that of the trunk 13 inches. The upper extremities consisted of perfect shoulder joints, but only 1/4 of each humerus was present.
If they were not all of contemporary date, it is clear from this case, and from the humerus of the Ursus spelaeus, before cited, as found in a floor of stalagmite, that the bear lived after the flint tools were manufactured, or in other words, that Man in this district preceded the cave-bear.
The peripheral portion consists of soft sarcomatous tissue, which invades the overlying soft parts. The articular cartilage long resists destruction. The ossifying sarcoma is met with most often in the femur and tibia, less frequently in the humerus, skull, pelvis, and jaws. In the long bones it may grow from the shaft, while the chondro-sarcoma more often originates at the extremities.
Injuries which act abruptly or instantaneously are illustrated in the crushing of a nerve by the sudden displacement of a sharp-edged fragment of bone, as may occur in comminuted fractures of the humerus. The symptoms include perversion or loss of sensation, motor paralysis, and atrophy of muscles, which show the reaction of degeneration from the eighth day onwards.
The triceps brachii is the principal structure which fills the space between the posterior border of the scapula and the humerus. The several heads originate for the most part on the border of the scapula, the deltoid tuberosity of the humerus and the shaft of the humerus. Insertion of this large muscular mass is effected by means of several tendons to the olecranon.
When the shaft of a long bone is affected, not only deformity, but even fracture may occur. Under these circumstances the humerus and femur appear to be the bones most likely to break; there is an associate deformity of the head, known as "craniotabes," together with pigeon-breast and various spinal curvature.
We can distinctly feel the spine of the scapula and its highest point, the acromion. It distinctly moves under the hand when the arm is rotated. The greater, externally; the lesser in front. The tuberosities of the humerus form the convexity of the shoulder. When the arm is raised, the convexity disappears, there is a slight depression in its place.
