What is the layer of epidermis that has pigment-producing melanocytes?
Melanocytes are present in basal layer of epidermis .
Which embryonic germ layer is bone derived from?
The mesoderm
What type of cell is responsible for the color and tone of our skin?
There are cells within the bottom layer of the epidermis (the stratum basale or stratum germinativum) called melanocytes. Melanocytes secrete a pigment called melanin which is responsible for giving our skin its color. Their main function though is to shield the nuclei of the keratinocytes (the main cells of the epidermis) to protect them from ultraviolet radiation from the sun. That's why we appear to tan in the sun.
Where is the location of melanocytes and Markel cells?
The melanocytes are the melanin-producing cell in the bottom layer of the epidermis of the skin. Merkel cells are receptor cells found in the skin of vertebrates. They aid in the ability to sense light touch.
What blastocyst produce the primordial germ cell?
Gastrula (early gastrula follow the blastula in the development sequence) ~ As a result of gastrulation, a three-layered embryo forms, each layer corresponding to a primary germ layer from which all body tissues develop.
What is the layer of epidermis that has pigment-producing melanocytes?
Melanocytes are present in basal layer of epidermis .
What do the melanocytes do?
Melanocytes are located in the bottom layer of the skin's epidermis, middle layer of the eye, inner ear, meninges, bones and heart. Melanocytes function is to produce melanin, which is the pigment primarily responsible for skin color.
The intestinal tract develops from which embryonic germ layer?
It develops from the endoderm germ layer
What marks the beginning of a germ layer development an embryo?
Gastrulation is first step towards germ layer development .
What layer in the eye contains melanocytes to dimish glare?
the choroid
What do the melanocyte do?
Melanocytes are located in the bottom layer of the skin's epidermis, middle layer of the eye, inner ear, meninges, bones and heart. Melanocytes function is to produce melanin, which is the pigment primarily responsible for skin color.
What germ layer is the tongue?
endoderm
Melanocytes lie within which layer of the skin?
stratum basale and upper dermis
What layer that contains melanocytes to diminish glare as light enters the posterior cavity?
choroid
From what germ layer does the mesoderm arise?
endoderm
What germ layer is the larynx derived from?
Ectoderm
Is trophoblast is present even as germ layer formation is occurring in human?
If your question is 'Is the trophoblast present during germ layer formation (i.e. gastrulation) ?' then the answer is YES
