What Is a Shoulder Sling?

Shoulder straps are also called shoulder clothes. They used to refer to Greek clothes. Modern clothes are part of clothes. Shoulder clothes are clothes of the Greeks in the sixth century BC. They are made of wool or linen, 18x6 feet of cloth, hanging from the left shoulder, hanging from the front, the other parts around the back, from the right armpit to the front, and then hanging Left shoulder, hang the other end behind. Shoulder clothing was originally the only clothing for men, and later, underwear or gowns were worn under the shoulder clothing. This can be seen in statues from the fourth and fifth centuries BC.

Later, in Roman times, and especially in the time of Jesus, shoulder garments became the clothes of educated or mentored. Will Jesus and his disciples pass through? In any case, Jesus and the disciples in the portraits of the past put on their shoulders to show their mentorship.

By the second century, the shoulder clothing was still 3: 1 (18X6 feet). Church clergy also used shoulder garments. In the fourth century, ordinary people gradually stopped using shoulder clothes. Only distinguished people still used shoulder clothes as uniforms, including church clerics1; and for convenience, folded the shoulder clothes into 12 to 9 inch wide shoulder straps. Later, because of the round dress (like today's sacrifice), instead of wrapping a part of the shoulder strap around the right armpit, the entire shoulder strap was hung on both shoulders, with both ends hanging from the left shoulder: front panel (Chest part) draped around the left shoulder to the back,

Vertebrates support the bones of the forelimbs. The evolution of shoulder straps in vertebrates of various classes is relatively complicated, with large variations in bone mass and the addition of membranous bone, usually not directly connected to the spine, but connected to the spine through ligaments and muscles.

The cartilage fish's shoulder strap is just a semi-circular cartilage rod that runs across the ventral surface of the chest.

The bones of the teleost fish are hard bones. In addition to the 3 basic bones of the scapula, coracoid and clavicle, there are 3 additional bones. In modern quadrupeds (terrestrial animals above amphibians), the cartilage primitive bone is basically composed of 3 pairs of bone fragments, that is, the scapula, black beak bone, and anterior black beak bone.

Among the three pairs of bone fragments, the most constant is the scapula. The other two pairs change more or less. One or both pairs are missing. Except for the clavicle, most of the reptiles have interclavicular bone, which is retained until the original mammals. . Birds adapt to flying life. The shape of the shoulder straps is special. The clavicle on both sides is connected in a "V" shape, which is elastic and acts as a crossbar. The lowest monopods in mammals still retain the reptile shoulder straps. The placental mammals have degenerated into the coracoids, the anterior coracoids and the interclavian bones have disappeared, and only the scapulae remain. The species retains the clavicle. Most of the species that are good at fast running and jumping, the clavicle is mostly degraded.
