The mesoderm layer consists of cells that give rise to structures such as muscles, bones, blood, and connective tissues in the developing embryo. It plays a crucial role in providing structural support and facilitating movement in the organism.
Mesoderm, specifically the visceral mesoderm layer consisting of mesoderm and endoderm.
The three primary tissue layers found in invertebrates are: Ectoderm: the outermost layer responsible for covering the body surface. Mesoderm: the middle layer giving rise to muscles, organs, and connective tissues. Endoderm: the innermost layer that develops into the digestive tract.
Connective tissues primarily develop from the mesoderm germ layer. The mesoderm gives rise to various connective tissue types, including bone, cartilage, blood, and adipose tissue. Some connective tissues, like those found in the head, may also have contributions from the ectoderm and neural crest cells, but the mesoderm is the principal source for most connective tissues in the body.
The notochord is an adult structure that is not derived from the same primary germ layer as the others. While structures like muscles, bones, and connective tissues derive from mesoderm, the notochord originates from the mesoderm but later forms from the embryonic ectoderm.
The three primary germ layers in the gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). Each layer gives rise to different tissues and organs in the developing embryo.
The heart is derived from the mesoderm, along with skeletal muscles and some other body organs.

Bone is derived from the mesoderm germ layer during early embryonic development. Mesoderm gives rise to the skeletal system, including bones, cartilage, muscles, and connective tissues.

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.
mesoderm The mesoderm forms: skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood (lymph cells), the kidney, and the spleen.
