Submucosa In the gastrointestinal tract, the submucosa is the layer of dense irregular connective tissue or loose connective tissue that supports the mucosa, as well as joins the mucosa to the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).mall intestinal submucosa (SIS) is submucosal tissue in the small intestines of vertebrates. SIS is harvested (typically from pigs) for transplanted structural material in several clinical applications, typically biologic meshes. They have low immunogenicity.

Subcutaneous tissue The subcutaneous tissue (from Latin subcutaneous, meaning beneath the skin), also called the hypodermis, hypoderm (from Greek, meaning beneath the skin), subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates. layer of tissue lies immediately below the dermis of vertebrate skin. It is often referred to as subcutaneous tissue though this is a less precise and anatomically inaccurate term. The hypodermis consists primarily of loose connective tissue and lobules of fat.

What are the names of the tissue layers of the stomach? The submucosa is a layer of dense connective tissue. It contains blood and lymph vessels, and is infiltrated by lymphoid cells, mast cells and macrophages. The muscle layer (muscularis) is composed of smooth muscle fibers. The fibers are oriented in three main directions. The external layer is longitudinal, the middle layer is circular and the internal layer is oblique. The serosa , a thin layer of serous membrane, is the outermost layer of stomach wall.

- Epithelial tissue is one of the four basic tissue types. Several features characterize epithelial tissue and distinguish it from connective tissue, muscle tissue, and nervous tissue. 1  Epithelial tissue covers surfaces with an uninterrupted layer of cells. Within the epithelium, the narrow spaces between cells are sealed off from the external environment by cell junctions near the free surface of the cells. 2  Compared to ordinary connective tissue, epithelial tissue has very little interstitial fluid. 3  Epithelial tissue is polarized.

- Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue. The other three types are connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body. There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal. These can be arranged in a single layer of cells as simple epithelium, either squamous, columnar or cuboidal, or in layers of two or more cells deep as stratified (layered), either squamous, columnar or cuboidal.

- Epithelial Tissue. 1  Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. 2  Epithelial cells form the thin layer of cells known as the endothelium, which is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. For example, the skin is composed of a layer of epithelial tissue (epidermis) that is supported by a layer of connective tissue. 2  It protects the internal structures of the body from damage and dehydration.

Epithelium Epithelium. Epithelium is a tissue composed of sheets of cells that are joined together in one or more layers. Epithelia cover the body surface, line body cavities and hollow organs, and form glands. simple epithelium is composed of a single layer of cells, all of which contact a nonliving basement membrane below. A stratified epithelium is composed of two or more cell layers.

Connective tissue Connective tissue (CT) is one of the four types of biological tissue that supports, connects or separates different types of tissues and organs in the body. It develops from the mesoderm. The other three types are epithelial, muscle, and nervous tissue. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue.

The Anatomy and Physiology of Animals/Tissues Worksheet The Anatomy and Physiology of Animals/Tissues Worksheet. 1. A tissue is: a collection of nuclei / a collection of organelles / a collection of cells / a collection of organs. 2. The four major tissue types are: epithelial / fat / connective / bone / muscle / nervous / blood. 3. Epidermal tissue: protects and supports the body / covers body surfaces / is responsible for movement / lines hollow organs / transmits nerve impulses / forms glands. 4. The inside of blood vessels is lined with: cuboidal epithelium / squamous epithelium / transitional epithelium / columnar epithelium.

- Simple epithelial tissue is composed of a single layer and stratified epithelial tissue composed of two or more layers. Connective Tissue. Connective tissue binds structures together, provides support and protection, fills, spaces, produces blood cells, and stores fat. The body uses this stored fat for energy, insulation, and organ protection.

- Epithelial tissues are classified according to the number of cell layers that make up the tissue and the shape of the cells. Simple epithelium is composed of a single layer of cells while stratified epithelium contains several layers.ntroduction to histology (Part 1). Tissues are composed of similar types of cells that work in a coordinated fashion to perform a common task, and the study of the tissue level of biological organization is histology. Four basic types of tissues are found in animals.

Tissue (biology) In biology, tissue is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.unctions of epithelial tissue: 1  the cells of the body surface form the outer layer of skin. 2  inside the body, epithelial cells form the lining of the mouth & alimentary canal & protect these organs. 3  epithelial tissues help in absorption of water & nutrients.

What Are Tissues? - Types & Explanation A tissue is one of the building blocks of an organism--either animal or plant. An organism is comprised of tissues, which are made up of individual cells. These cells share a similar structure (how they're built) and function (what they do).The study of tissues is a field known as histology.pecific epithelial tissue types consist of the combination of the cell shape and number of cell layers. For example, simple cuboidal epithelial tissue describes tissue that is one cell layer thick, with cells that are cube-like in appearance.

- Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. In this tissue, cells are flattened, joined tightly together, and stacked. The major function of this tissue type is protection, as it is found in areas that undergo wear-and-tear. This tissue comes in two types, keratinized and non-keratinized.

Human skin The skin consists of three layers of tissue: the epidermis, an outermost layer that contains the primary protective structure, the stratum corneum; the dermis, a fibrous layer that supports and strengthens the epidermis; and the subcutis, a subcutaneous layer of fat beneath the dermis that supplies nutrients to the other two layers and that cushions and insulates the body.

Submucosa The submucosa is a thin layer of tissue in various organs of the gastrointestinal, respiratory, and genitourinary tracts. It is the layer of dense irregular connective tissue that supports the mucosa and joins it to the muscular layer, the bulk of overlying smooth muscle. The submucosa is to a mucous membrane what the subserosa is to a serous membrane.
