What is first connective tissue in the embryo?
The first connective tissue in the embryo is called mesenchyme. Mesenchyme is a type of embryonic tissue that gives rise to various connective tissues in the body, such as bone, cartilage, and muscle. It also plays a role in the development of organs and blood vessels.
What is mesenchyme tissue?
First, a little background (skip down to the short answer if you already know this) because it helps to first take a couple steps backwards in order to understand. You can trace the major tissue types in the human body back to the embryo, which has three "germ layers" called endoderm (inner layer - differentiates into the "inner" coverings like epithelial linings of organs, etc), mesoderm (middle layer - differentiates into mesenchyme - connective tissue, etc.), and ectoderm (outer layer - differentiates into "outer" protective coverings like epidermis, enamel, but also forms the nervous system).It boils down to this...ectoderm and endoderm form the "parenchymal" tissue or "parenchyma." This tissue is composed of the highly specialized cells that "do the work" in an organ. For example, hepatocytes in the liver are cells that make proteins, make cholesterol, bile salts, etc. Another example would be the parietal cells in the stomach that release hydrochloric acid, and on and on and on.The mesoderm differentiates into the mesenchyme, which is basically "everything else." The cells in these tissues play a support function. For example, mesenchymal tissue aids parenchymal tissues by providing blood, nutrients, structural support in the form of connective tissues.Short Answer: Mesenchyme originates from the mesoderm (loose connective tissue) and eventually differentiates into the body's connective tissues (eg supporting framework in muscle, skin, organs, the ligaments, tendons, cartilage, bone, etc.), AND it also differentiates into blood vesselsand lymphatic vessels that circulate oxygen, nutrients, enzymes/ proteins, hormones, white blood cells, they clear waste, etc. Mesenchyme tissue does the "grunt work." Therefore, these 3 categories essentially play various support roles for the specialized, "functional" (parenchymal) cells in the tissues/ organs.
What type of connective tissue has fibreless matrix?
The type of connective tissue that has a fibreless matrix is known as "embryonic connective tissue," specifically the gelatinous substance called "mucous connective tissue" or Wharton's jelly. This type of tissue is primarily found in the umbilical cord and serves to support and protect the blood vessels. Its matrix is rich in ground substance but lacks the prominent fibers seen in other connective tissues, making it unique in structure and function.
Which is the most atypical connective tissue since it does not connect things or provide structural support?
BLOOD. It does not conncet things or give mechanical support. It is classified as connective tissue because it develops from mesenchyme and consists of blood cells, surronded by a nonliving fluid matrix called blood plasma.
Where does muscle tissue develop?
Muscle tissues are derived from the mesodermal layer of the embryonic germ cells through a process called myogenesis.

What are tissues that bind and support other tissues called?
Tissues that bind and support other tissues are called connective tissues. These tissues have varying degrees of flexibility and strength to provide structural support and stability to the body. Examples include tendons, ligaments, adipose tissue, and cartilage.
What are tough connective tissues called?
Tendons

What are Connective tissues that connects muscle to bone are called?
they are called ligiments
What are the cells called that form skeletal connective tissues?
Fibroblasts.
Differentiation of cells and tissues in the embryo is called?
cellular differentiation
What kind of tissues joins other tissues together?
Connective tissues are responsible for joining other tissues together. These tissues provide structural support and help maintain the physical integrity of organs and body structures. Examples of connective tissues include tendons, ligaments, and cartilage.

What is the layer of glycoproteins that prevents leakage of materials from connective tissues called?
The layer of glycoproteins that prevents leakage of materials from connective tissues is called the basement membrane. It acts as a selective filter, regulating the passage of substances between the connective tissue and the surrounding structures.
What are cancers of connective tissue called?
Cancers of connective tissue are typically referred to as sarcomas. Sarcomas can develop in various types of connective tissues, such as bone, muscle, fat, and cartilage. Examples include osteosarcoma, liposarcoma, and chondrosarcoma.
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.
