Epithelial tissue, also referred to as epithelium, refers to the sheets of cells that line all surfaces of the body. Connective tissue binds together, protects, and supports structures of the body. We will cover epithelial tissue and connective tissue in this module. Muscle tissue and nervous tissue will be covered in the next module.
What are the cells of connective tissue?
The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes. The term "connective tissue" (in German, Bindegewebe) was introduced in 1830 by Johannes Peter Müller. The tissue was already recognized as a distinct class in the 18th century.
What type of connective tissue has elastic fibers?
Elastic connective tissue: Elastic tissue contains elastin fibers in addition to collagen fibers, which allows the tissue to return to its original length after stretching. This tissue can be found in the ligaments that form the vocal cords and the walls of large blood vessels, for example.

Connective tissue is made up of cells, fibers, and a gel-like substance. Types of connective tissue include bone, cartilage, fat, blood, and lymphatic tissue.
What is the function of epithelial cells?
In addition, specialized epithelial cells function as receptors for special senses (smell, taste, hearing, and vision). Epithelial cells are numerous, exist in close apposition to each other, and form specialized junctions to create a barrier between connective tissues and free surfaces. Free surfaces of the body include the outer surface of internal organs, lining of body cavities, exterior surface of the body, tubes and ducts. The extracellular matrix of epithelial tissue is minimal and lacks additional structures. Although epithelial tissue is avascular, it is innervated.
Which layer of the epithelial cell is closest to the basement membrane?
The basal surface is nearest to the basement membrane. The basement membrane itself creates a thin barrier between connective tissues and the most basal layer of epithelial cells. Specialized junctions called hemidesmosomes secure the epithelial cells on the basement membrane.
What are the different types of tissue?
There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
How many types of muscle tissue are there?
Muscle tissue is easily distinguishable by its highly organized bundles of cells. Although there are three types of muscle tissue with unique cell morphologies, the fiber bundles of each tissue type are arranged in parallel oriented on the long axis and are distinct from surrounding connective tissue.

We will cover epithelial tissue and connective tissue in this module. Muscle tissue and nervous tissue will be covered in the next module.
Which tissue supports and connects other tissues?
Supporting and connective tissues: Connective tissues support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body.
What type of tissue contracts to cause movement?
Muscle tissue and nervous tissue will be covered in the next module. Muscle tissue contracts to cause movement, while nervous tissue sends electrical signals to allow communication throughout the body. Four Types of Tissue: The four types of tissues are exemplified in nervous tissue, stratified squamous epithelial tissue, cardiac muscle tissue, ...
How are epithelial tissues classified?
Epithelial tissues are classified according to the shape of the cells and number of the cell layers formed ( (Figure) ).
Which type of tissue defends the body from microorganisms that enter the body?
Defense : Specialized cells in connective tissue defend the body from microorganisms that enter the body.
How are epithelial cells connected?
Epithelial cells are closely connected and are not separated by intracellular material. These cells are held together or interact with each other via junctions, or connections between the cells. Three of these junctions hold the cells together, while one allows for cell-to-cell communication.
How many layers are there in stratified cells?
Stratified: More than one layer of cells, with only the basal layer resting on the basal lamina of the basement membrane. This can be just a few layers or dozens of layers depending on the location.

Other kinds of connective tissues include fibrous, elastic, and lymphoid connective tissues. Fibroareolar tissue is a mix of fibrous and areolar tissue. Fibromuscular tissue is made up of fibrous tissue and muscular tissue. New vascularised connective tissue that forms in the process of wound healing is termed granulation tissue.
Why do adipose cells keep together?
Although there is no dense collagen network in adipose tissue, groups of adipose cells are kept together by collagen fibers and collagen sheets in order to keep fat tissue under compression in place (for example, the sole of the foot). Both the ground substance and proteins (fibers) create the matrix for connective tissue.
What is the difference between dense and loose connective tissue?
Loose and dense connective tissue are distinguished by the ratio of ground substance to fibrous tissue. Loose connective tissue has much more ground substance and a relative lack of fibrous tissue, while the reverse is true of dense connective tissue.

Four main tissue types and their functions
Overview
Connective tissue is one of the many basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. In embryology it develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that envelop the brain and spinal cord are composed of dense inert connective tissue. All connective tissue consists of three main components: fibers (
Types
Connective tissue can be broadly classified into connective tissue proper and special connective tissue. Connective tissue proper consists of loose connective tissue and dense connective tissue (which is further subdivided into dense regular and dense irregular connective tissues.) Loose and dense connective tissue are distinguished by the ratio of ground substance to fibrous tissue. Loose connective tissue has much more ground substance and a relative lack of fibrous tissue, …
Function
Connective tissue has a wide variety of functions that depend on the types of cells and the different classes of fibers involved. Loose and dense irregular connective tissue, formed mainly by fibroblasts and collagen fibers, have an important role in providing a medium for oxygen and nutrients to diffuse from capillaries to cells, and carbon dioxide and waste substances to diffuse from cells back into circulation. They also allow organs to resist stretching and tearing forces. D…
Clinical significance
There are many types of connective tissue disorders, such as:
• Connective tissue neoplasms including sarcomas such as hemangiopericytoma and malignant peripheral nerve sheath tumor in nervous tissue.
• Congenital diseases include Marfan syndrome and Ehlers-Danlos Syndrome.
