is ectoderm uniformly pigmented
Gastrulation is defined as a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm. These develop into the respiratory and digestive organs.
Agnatha are ancient jawless fish that include lampreys and hagfish. They are also probably the earliest vertebrates and have ectoderm.
The Ectoderm

the three germ layers on a squid are the ectoderm, endoderm and mesoderm
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.
is ectoderm uniformly pigmented
Yes, chordates have three primary tissue layers: ectoderm, endoderm, and mesoderm. These layers give rise to different organs and systems in the body during development.
From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm. Each of the three layers develops into a different part of the embryo: the endoderm into the respiratory, auditory, and digestive system; the mesoderm into the skeleton and muscles; and the ectoderm into the skin, tooth enamel, and nervous system.
just look up ectoderm by itself you will find it
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
That is correct. In case of the embryo, you have three layers, in initial period. The cells from the ectoderm enter the mesoderm to form the neural tube. So the neural tube is formed by invagination of the ectoderm in the mesoderm. Your nervous system is developed from this neural tube.In vertebrates, ectoderm gives rise to hair, skin, nails or hooves, the lens of the eye, the epithelia (surface, or lining, tissues) of sense organs, the nasal cavity, the sinuses, the mouth (including tooth enamel), the anal canal and nervous tissue, including the pituitary body.
ectoderm is the young epidermis, same with endoderm, it is the young gastrodermis.
