Humans and Tails

Man and authors marvel at the complexity of the human body when human and tail study human anatomy in biology textbooks. Characteristics such as our opposite thumb, bipedal walking and cognitive abilities are praised, but humans suffer serious disadvantage. We lack the main accessories that contribute to our daily lives; they can greatly improve the quality of life. One such attachment is the tail; it is that some people are accustomed to their existing lifestyle, and despite their strengths, they avoid any change.

Coccyx or coccyx: Humans do not have visible outer tails clearly because the current version of humans do not need living tree tails like the earliest human ancestry. However, the human bone still has coccyx and coccyx. In the fetus, the tail is absorbed during development. The coccyx is now a muscle anchor, which is not the original cause, so this is why it is considered a residual. "These endocrine cells of the fetal appendix have been shown to produce various biogenic amines and peptide hormones that contribute to various biologically controlled (steady state) mechanisms," Loren G. Martin The professor told Scientific American. It can also be used as part of adult immunity and lymphatic system

The coccyx or coccyx is the residue of the lost tail. Every mammal has a tail at some stage of its development; during the period of human embryogenesis 14 to 22, it exists for 4 weeks. This tail is most prominent in human embryos at 31 to 35 days of age. It still explains why it is not further degraded, and still has some ancillary features, such as muscle junctions, but the coccyx at the end of the spine is the original supporting a balance and activity I lose the function. The coccyx acts as an attachment site for tendons, ligaments and muscles. It can also be used as an insertion point for certain muscles of the pelvic floor. In rare cases, birth defects bring about a short tail structure at birth. Since 1884, 23 infants with this structure at birth have been reported in medical literature. In rare cases, it is judged that the spine and skull are perfectly normal

At the sixth week of pregnancy, the human embryo has a tail with several vertebrae. However, during the next few weeks of development, the tail disappears and over time, the vertebrae merge into the coccyx or coccyx of the adult. The difference between humans and their relatives and other primates is that they have no tail, but it is not clear why monkeys lose their tails. In rare cases, human babies have a tail at birth. In modern medical literature, such tails are vertebra-free and generally harmless, but some are related to the spina bifida (the vertebra does not completely surround the spinal cord). Human baby's tail is usually surgically removed without complications.
