But most animals have a bilateral symmetry, and develop from three germ layers, an ectoderm, endoderm, and a middle layer of mesoderm, and are triploblastic.
Hewan triploblastik mempunyai 3 lapisan lembaga, yaitu ektoderm (lapisan luar), mesoderm (lapisan tengah) dan endoderm (lapisan dalam).
The endoderm is one of the germ layers formed during animal embryonic development.
Endoderm adalah salah satu lapisan germinal yang terbentuk selama embriogenesis hewan.
The endoderm forms: the pharynx, the esophagus, the stomach, the small intestine, the colon, the liver, the pancreas, the bladder, the epithelial parts of the trachea and bronchi, the lungs, the thyroid, and the parathyroid.
Endoderm membentuk: lambung, usus besar, hati, pankreas, kandung kemih, bagian-bagian epitel dari trakea, paru-paru, faring, tiroid, paratiroid, dan usus.
The mesoderm germ layer forms in the embryo of a triploblastic animal.
Lapisan germinal mesoderm terbentuk dalam embrio hewan triploblastik.
During gastrulation, some of the cells migrating inward contribute to the mesoderm, an additional layer between the endoderm and the ectoderm.
Selama gastrulasi, beberapa sel yang bermigrasi ke dalam berkontribusi pada mesoderm, lapisan tambahan antara endoderm dan ektoderm.
Organs formed inside a coelom can freely move, grow, and develop independently of the body wall while fluid cushions, protects them from shocks.
Organ yang terbentuk di dalam selom dapat dengan bebas bergerak, tumbuh, dan berkembang secara independen dari dinding tubuh sementara cairan menjadi bantalan dan melindungi mereka dari guncangan.
The mesoderm has several components which develop into tissues: axial mesoderm, intermediate mesoderm, paraxial mesoderm, and lateral plate mesoderm.
Mesoderm memiliki beberapa komponen yang berkembang menjadi jaringan: mesoderm intermediet, mesoderm paraksial, mesoderm pelat lateral, dan korda-mesoderm.
The intermediate mesoderm develops into kidneys and gonads.
Mesoderm intermediet berkembang menjadi ginjal dan gonad.
The paraxial mesoderm develops into cartilage, skeletal muscle, and dermis.
Mesoderm paraksial berkembang menjadi tulang rawan, otot rangka, dan dermis.
The lateral plate mesoderm develops into the circulatory system (including the heart and spleen), the wall of the gut, and wall of the human body.
Mesoderm pelat lateral berkembang menjadi sistem sirkulasi (termasuk jantung dan limpa), dinding usus, dan dinding tubuh manusia.
Through cell signaling cascades and interactions with the ectodermal and endodermal cells, the mesodermal cells begin the process of differentiation.
Melalui kaskade pensinyalan sel dan interaksi dengan sel ektodermal dan endodermal, sel mesodermal memulai proses diferensiasi.
The mesoderm forms: muscle (smooth and striated), bone, cartilage, connective tissue, adipose tissue, circulatory system, lymphatic system, dermis, dentine of teeth, genitourinary system, serous membranes, spleen and notochord.
Mesoderm membentuk: otot (polos dan lurik), tulang, tulang rawan, jaringan ikat, jaringan adiposa, sistem peredaran darah, sistem limfatik, dermis, sistem genitourinari, membran serosa, dan notokord.
The ectoderm generates the outer layer of the embryo, and it forms from the embryo's epiblast.
Ektoderm menghasilkan lapisan luar embrio, dan terbentuk dari epiblas embrio.
The ectoderm develops into the surface ectoderm, neural crest, and the neural tube.
Ektoderm berkembang menjadi ektoderm permukaan, bumbung neural, dan tabung saraf.
The surface ectoderm develops into: epidermis, hair, nails, lens of the eye, sebaceous glands, cornea, tooth enamel, the epithelium of the mouth and nose.
Ektoderm permukaan berkembang menjadi: epidermis, rambut, kuku, lensa mata, kelenjar minyak, kornea, email gigi, epitel mulut dan hidung.
The neural crest of the ectoderm develops into: peripheral nervous system, adrenal medulla, melanocytes, facial cartilage.
Bumbung neural dari ektoderm berkembang menjadi: sistem saraf tepi, medula adrenal, melanosit, tulang rawan wajah, dentin gigi.
