The Ectoderm is the start of a tissue that covers the body surfaces. It emerges first and forms from the outermost of the germ layers.
The Ectoderm forms: the central nervous system, the lens of the eye, cranial and sensory, the ganglia and nerves, pigment cells, head connective tissues, the epidermis, hair, and mammary glands

∙ 13y agoAt the beginning of week three after fertilization the embryo is in the the form of a bilaminar disc with the epiblast layer on top, continuous with the amniotic cavity and the hypoblast layer below, continuous with the yolk sac. Gastrulation is process by which this bilaminar (2 layer) disc becomes three germ layers: the endoderm, the mesoderm and the ectoderm. The primitive streak forms from a thickened band of epiblast cells. These cells proliferate and migrate in between the two layers. It is therefore the primitive streak which forms the mesoderm (middle layer). The epiblast layer is now the embryonic ectoderm and the hypoblast layer is the embryonic endoderm.

Ectoderm
Is the ectoderm uniformly pigmented?
is ectoderm uniformly pigmented
The three primary germ layers that form during the embryonic development of mollusks are?
The endoderm, mesoderm, and ectoderm
The three types of cells that can form during differentation?
the Mesoderm the Endoderm the Ectoderm This is correct and confirmed by wiki; http://en.wikipedia.org/wiki/Germ_layer
Does ectoderm form tooth enamel?
yes!!
Does the ectoderm form neural tissues?
The ectoderm nearest the embryonic midline - often described as the neuroectoderm - does form into the neural tube, the embryonic structure from which the nervous system develops. However, more lateral ectoderm matures into skin and associated tissues.
What germ layer is nervous tissue found?
Neuronal ectoderm
From which of these layers do hair nails epithelial tissue develop?
Ectoderm
Is the ectoderm uniformly pigmented?
is ectoderm uniformly pigmented
What are the three germ layers of a gastrula?
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.
What is an ectoderm in embryology?
just look up ectoderm by itself you will find it
The three primary germ layers that form during the embryonic development of mollusks are?
The endoderm, mesoderm, and ectoderm
Is the first obvious signthat the nervous system is forming in the embryo is the thickening of the surface ectoderm to form the neural plate?
No
What germ layer does the tissue of the peripheral nervous system develop from?
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
Is epidermis and ectoderm the same thing?
ectoderm is the young epidermis, same with endoderm, it is the young gastrodermis.
What embryonic germ layer is epithelial tissues?
Ectoderm, endoderm, and mesoderm can produce epithelial tissues
