Muscles differentiate from which tissue is it ectoderm endoderm mesoderm or a combo of any two?

The mesoderm. It is the forerunner of muscles, most of the skeleton, the circulatory, reproductive and excretory systems, connective tissues and integument.

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.
The heart muscles bones and blood develop primarily from ectoderm mesoderm endoderm the placenta or the gray crescent?
ectoderm
What are structres derived from endoderm?
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.
Muscles differentiate from which tissue?
Mesoderm
What germ layer gives rise to the skeletal muscles?
All from Mesoderm, except the eye muscles that originate from ectoderm
Why is the epithelium derived from ectoderm mesoderm endoderm and connective tissue mesoderm only?
Actually ur question is itself not correct so the 'WHY" part cannot be answered. Epithelial tissue is a lining tissue which can be present in any organ.the mesoderm gives rise to organs like-muscles / bones / connective tissue / blood and lymph vessels / kidney / gonads and the cortex of suprarenal glands. ectoderm-nervous system epidermis and so on and endodermto GIT liver lungs pancreas and GIT so for example if u consider the epithelial tissue of lungs----its derived from endodermas lung as a whole is derived from endoderm.
Where are the mesenchymal cells found?
There are different forms of mesenchymal cells and tissues found almost everywhere in the body, and these tissues can be thought of, broadly, as: connective tissues, blood vessels, and lymphatic vessels.Mesenchymal cells/ tissues originate from the middle embryonic germ layer (there are 3 - endoderm, mesoderm, ectoderm) called the "mesoderm" and differentiate into the body's various connective tissues found in bone, cartilage, ligaments, tendons, muscles, skin, organs, extracellular matrix, as they also form the blood vessels and lymphatic vessels.
8 What structures will each of the 3 germ layers differentiate in to for a developing human embryo?
The ectoderm is the germ layer covering the surface of the embryo and develops into the outer covering of the animal (in our case, our skin) and in some phyla, the nervous system. The mesoderm forms the muscles and most other organs between the digestive tract and the outer covering of the animal. The endoderm, which is the innermost germ layer, lines the developing digestive tube (referred to as the archenteron) and gives rise to the lining of the digestive tract or cavity and organs derived from it, such as the liver and lungs.
Does ectoderm form nervous tissue?
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.
What forms from the three layers of the gastrula?
The primary germ layers (endoderm, mesoderm, and ectoderm) are formed and organized in their proper locations during gastrulation. Endoderm, the most internal germ layer, forms the lining of the gut and other internal organs. Ectoderm, the most exterior germ layer, forms skin, brain, the nervous system, and other external tissues. Mesoderm, the the middle germ layer, forms muscle, the skeletal system, and the circulatory system.
What are the 3 primary germ layers and what do they form in fertilization?
There are 3 primary germ layers: Endoderm, Mesoderm and EctodermENDODERM forms:- respiratory tract (trachea, bronchi, alveoli, lungs),- endocrine glands and organs (thyroid glands, thymus),- urinary system (urethra, urinary bladder),- gastrointestinal tract (liver, pancreas, alimentary canal(EXCEPT mouth, pharynx, TERMINAL part of rectum),- auditory system (epithelium of auditory tube and tympaniccavity)MESODERM forms:- Axial mesoderm (prechordal plate, notochord),- Paraxial mesoderm (Somites: muscles, bones, cartilage),- Intermediate mesoderm (gonads, kidney, adrenal cortex),- Lateral mesoderm: (cardiovascular organs:heart, bloodvessels;connective tissue, mesenchymalcells; limb buds),ECTODERM:- nervous system (spine, peripheral nerves, brain),- tooth enamel,- epidermis- lining of mouth, anus, nostrils- sweat glands- hair, nails
What tissues make up skeletal muscle?
Muscles come embryologically from the mesodermal layer. A few - such as the smooth muscle in nipples and the cilliary muscle in the eye come from the ectoderm Most body musculature comes from the somites (blocks of mesoderm in the embryo). Limb muscle comes from the mesoderm of the limb buds. Lateral plate mesoderm gives rise to some anterior body wall muscles.
