The endoderm, the innermost embryonic layer, becomes the digestive organs and other accessory organs such as the liver and pancreas. The ectoderm becomes the epidermis and nervous system. The mesoderm becomes muscles, bones, cartilage, blood, and reproductive organs.
No, muscle tissue is not formed by the endoderm. Muscle tissue is derived from the mesoderm layer during embryonic development. The endoderm gives rise to the lining of many internal organs such as the gastrointestinal tract and respiratory system.
The tongue is derived from the ectoderm germ layer during early embryonic development.
Unlike the rest of the abdominal organs which are derived from endoderm, the spleen is mesodermal in origin.

Diploblastic is generally referred to as "having a body derived from only two embryonic cell layers (ectoderm and endoderm, but no mesoderm), as in sponges and coelenterates".

Oral mucosa is very tough to tolerate all sort of insults or misuses done to it. That is why it is derived from the skin or ectoderm. Mucosa from the gastrointestinal tract is derived from the endoderm.
The three germ layers of a gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the developing embryo through a process known as gastrulation.
Prussian embryologist Robert Remak coined the term "endoderm" in 1835. The endoderm is the innermost of the three primary germ layers of an embryo. The endoderm may also be called the hypoblast.
