Human tissue is the biological material that makes up the body of a human being. It is composed of cells, extracellular matrix, and various substances that help the cells to function properly. There are four main types of human tissue: epithelial, connective, muscular, and nervous tissue.

Epithelial tissue is found lining the surfaces of the body, including the skin, blood vessels, and internal organs. It is made up of tightly packed cells that form a protective barrier and help to regulate the exchange of substances between the body and the environment. Epithelial tissue is classified based on the number of cell layers and the shape of the cells. Simple epithelial tissue has a single layer of cells, while stratified epithelial tissue has multiple layers. The cells of epithelial tissue can be squamous, cuboidal, or columnar in shape.

Connective tissue is found throughout the body and provides support, protection, and connection between different body parts. It is made up of cells and an extracellular matrix that consists of fibers and ground substance. There are several types of connective tissue, including adipose (fat) tissue, cartilage, bone, and blood. Adipose tissue stores energy and helps to insulate the body. Cartilage is a flexible, elastic tissue that cushions joints and allows for movement. Bone is a hard, rigid tissue that provides support and protection for the body. Blood is a fluid connective tissue that carries oxygen, nutrients, and hormones to cells and removes waste products from the body.

Muscular tissue is responsible for movement and the generation of force. It is made up of cells called muscle fibers that can contract and relax. There are three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscle is under voluntary control and is responsible for movement of the bones and other structures. Cardiac muscle is found in the heart and is responsible for pumping blood throughout the body. Smooth muscle is found in the walls of internal organs and helps to move substances through the body.

Nervous tissue is found in the brain, spinal cord, and nerves and is responsible for transmitting and processing information. It is made up of cells called neurons and glial cells. Neurons are responsible for transmitting signals through the body, while glial cells provide support and protection for the neurons.

In conclusion, there are four main types of human tissue: epithelial, connective, muscular, and nervous tissue. Each type of tissue has specific functions and is found in different parts of the body. Understanding the different types of tissue is important for understanding how the body functions and for diagnosing and treating various medical conditions.

. The zygote, or fertilized egg, is a single cell formed by the fusion of an egg and sperm cell. The body gets rid of the viral load naturally when external forces, i. Each subtype, in turn, has a special structure and function. Muscle and nervous tissues will be discussed only briefly in this chapter. The lining of the mouth and esophagus are also examples of epithelial tissue. Types of Tissue in Human Body Muscle Tissue As mentioned earlier, human tissue is made up of particular kinds of cells that work together.

Many human cells have the primary job of producing and secreting a particular substance, such as a hormone or an enzyme. Nervous tissue Cells of the nervous system are highly specialized to transmit electrical impulses around the body. Just as cells join together to form tissues, different tissues join together to form organs. The four types of tissues are exemplified in nervous tissue, stratified squamous epithelial tissue, cardiac muscle tissue, and connective tissue in small intestine. There are three basic shapes of epithelial cells, squamous, cuboidal, and columnar. They help in movement, contraction, and other physiological activities.

Mucous, produced by the epithelial exocrine glands, covers the epithelial layer. They are found in the walls of blood vessels and in the reproductive, gastrointestinal, and respiratory tracts. Tissues are either classified as proper, embryonic, or specialized. Cells in the Human Body Based on the tissue they form 1. Different types of tissues form membranes that enclose organs, provide a friction-free interaction between organs, and keep organs together.

Alternatively, epithelial tissue can be involved in absorption, secretion and movement of substances. There are cells suspended in the matrix. But what exactly does that mean? A single organ can have different types of epithelial tissue based on the substances to which different surfaces are exposed. Also Refer:  Epithelial Tissue They are formed by cells which cover the external parts of the body organs and lines the organ surfaces such as the surface of the skin,  the reproductive tract, the airways, and the inner lining of the digestive tract. These tissues often have a protective role, and the extent of friction or abrasion often determines the number of layers of cells. The membrane lines the joint cavity and contains fibroblasts that produce hyaluronan, which leads to the production of synovial fluid, a natural lubricant that enables the bones of a joint to move freely against one another.

The matrix is produced by cells called chondroblasts. The contraction of your pupil and the movement of digested food through your intestines is the work of smooth muscle. They are controlled by Nervous tissue This tissue is mostly present in the entire The nerve cells are the longest cells in the body. The apical side contains protein channels and pumps that move nutrients into the cell. Following the cells of the ectodermal germ layer, they too become more restricted in what they can form.

Epithelial Tissue (Epithelium)

Our tissues can be categorized into four major types: Epithelial, Connective, Muscle, and Nervous. There are three types of loose connective tissue. Muscle tissue is made up of excitable cells that are long and fibrous. The small tunnels, canaliculi, connect osteocytes in the different layers of an osteon. Cartilage can be classified as hyaline cartilage, elastic cartilage, or fibrocartilage. Cells in the human body are of different types based on their structure and function.

Supportive cells These are the cells that are present as support to adjacent cells. Epithelial tissue protects the body and its internal organs, secretes substances such as hormones in addition to mucus, and absorbs substances such as nutrients. This tissue is also found in your fat layers, lymph nodes, and red bone marrow. The study of the shape and arrangement of cells in tissue is called histology. Simple cuboidal epithelia line both those structures. Also Read:Â Â Nervous Tissue They are the main tissue components of the brain and spinal cord in the central nervous system.

Kenhub does not provide medical advice. Loose connective tissue consists of thin, loosely arranged collagen fibers in a viscous ground substance. A serous membrane lines the cavities of the body that do not open to the external environment. Organs are organized into organ systems to perform functions. Because the bone matrix is very dense, the osteocytes get their nutrition from the central canal via tiny canals called canaliculi. Functions of Connective Tissue The connective tissue functions by providing shape and maintains the position of different organs in the body. Stratified squamous epithelia are found in skin, with many dead, keratinized cells providing protection against water and nutrient loss.

A synovial membrane is a type of connective tissue membrane that lines the cavity of a freely movable joint. Connective tissue can be classified as connective tissue proper, cartilage, bone, or blood. And don't forget about the most important muscle of all: the heart. Like skeletal muscle, actin and myosin also give cardiac muscle a striated appearance. One tissue donor can enhance or save the life of more than 50 people! In addition to muscle tissue, we have connective, epithelial and nervous tissue in the body.
