difference between ectoderm, mesoderm and endoderm
Answers
Explanation:
The difference is that basically the mesenchyme forms a part of the mesoderm. Here are some more details and explanations.
The mesoderm is “the middle layer of the three primary germ layers of the embryo, lying between the ectoderm and the endoderm. From it are derived the connective tissue, bone and cartilage, muscle, blood and blood vessels, lymphatics and lymphoid organs, notochord, pleura, pericardium, peritoneum, kidney, and gonads.”
The mesenchyme is “[mes- + Greek ‘enchyma’ infusion] the meshwork of loosely organized embryonic connective tissue in the mesoderm from which are formed the connective tissues of the body, and also the blood vessels and lymphatic vessels.”
“Mesenchymal cells are able to develop into the tissues of the lymphatic and circulatory systems, as well as connective tissues throughout the body, such as bone and cartilage. A sarcoma is a malignant cancer of mesenchymal cells.”
