types of tissues

Types of Tissues in the Body By: Jessica Ruday Connective Tissue Connective Tissue is found throughout our bodies. The four types of tissues are exemplified in nervous tissue, stratified squamous epithelial tissue, cardiac muscle tissue, and connective tissue in small intestine. A fourth serous membrane, the peritoneum, lines the peritoneal cavity, covering the abdominal organs and forming double sheets of mesenteries that suspend many of the digestive organs. These structures help attach muscles to bones and link bones together at joints. Learn about the main tissue types and organ systems of the body and how they work together. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body (Figure 1).

EPITHELIUM … A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Each of these lines of embryonic cells forms the distinct germ layers from which all the tissues and organs of the human body eventually form. After fertilization the zygote gives rise to rapid mitotic cycles, generating many cells to form the embryo. types 1. The skin is an example of a cutaneous membrane. Chapter 1. Just as knowing the structure and function of cells helps you in your study of tissues, knowledge of tissues will help you understand how organs function. Learn more about tissues in this article. Connective tissue is derived from the third germ layer, the mesoderm, which is the same source of origin of muscle tissue. The human tissue is classified into four basic categories: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Nervous Tissue: This is a special kind of tissue which is responsible for receiving, transmitting and … Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern that achieves the tissue’s functions. A tissue membrane is a thin layer or sheet of cells that covers the outside of the body (for example, skin), the organs (for example, pericardium), internal passageways that lead to the exterior of the body (for example, abdominal mesenteries), and the lining of the moveable joint cavities. Three main different types of tissue are follows-Epidermal tissue - It is composed of closely packed cells which have thick walls. Muscle tissue, which responds to stimulation and contracts to provide movement, is divided into three major types: skeletal (voluntary) muscles, smooth muscles, and the cardiac muscle in the heart. These membranes are found lining the external body surface (cutaneous membranes and mucous membranes) or lining the internal body cavities (serous membranes). By definition, tissues are absent from unicellular organisms. Tissue - is a group of similar cells specialized for the performance of a common function. A disruption of the structure is a sign of injury or disease. Try this amazing 4 Types Of Tissue (Science) quiz which has been attempted 1064 times by avid quiz takers. Types of tissues . In the human body there are more than 200 types of cells that are organized to form tissues that can be of four basic types: 1. These all types of tissues derived from embryonic tissue (ectoderm, mesoderm, endoderm) and sometimes they vary according to species. Each type of tissue differ from each other in structure which in turn determines its function. Connective tissue, as its name implies, binds the cells and organs of the body together. Muscle and nervous tissues will be discussed only briefly in this chapter. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Cells are the body’s smallest functional units they are grouped together to form tissues, each of which has specialized functions,e g.blood , muscle Study of tissues is called histology. Meristematic tissues give rise to permanent tissues. The first embryonic cells generated have the ability to differentiate into any type of cell in the body and, as such, are called totipotent, meaning each has the capacity to divide, differentiate, and develop into a new organism. Meristematic Tissue in Plants. Tissues are organized into four broad categories based on structural and functional similarities. Three different types of tissues- epidermal tissues, ground tissue and vascular tissues. Each germ layer is identified by its relative position: ectoderm (ecto- = “outer”), mesoderm (meso- = “middle”), and endoderm (endo- = “inner”). Three serous membranes are found lining the thoracic cavity; two membranes that cover the lungs (pleura) and one membrane that covers the heart (pericardium). Following the cells of the ectodermal germ layer, they too become more restricted in what they can form. Add to favorites 0 favs. - The study of tissues is called Histology - the cells in multicellular animal maybe divided into 2. Membranes are layers of connective and epithelial tissues that line the external environment and internal body cavities of the body. Overview. Body structure and homeostasis. As these cells become specialized, they lose their ability to differentiate into all tissues. These membranes line the coelomic cavities of the body, that is, those cavities that do not open to the outside, and they cover the organs located within those cavities. Mucous, produced by the epithelial exocrine glands, covers the epithelial layer. Each germ layer is identified by its relative position: ectoderm (ecto– = “outer”), mesoderm (meso– = “middle”), and endoderm (endo– = “inner”). The Cardiovascular System: Blood, Chapter 19. Connective tissue integrates the various parts of the body and provides support and protection to organs. The type of connective tissue cell that is the most numerous. The Nervous System and Nervous Tissue, 12.1 Structure and Function of the Nervous System, Chapter 13. Two other types of connective tissue are dense regular tissue and dense irregular tissue. Muscle tissue contracts forcefully when excited, providing movement. Each type of tissue consists of different types of cells, has different functions, and is located in different places. The three types of muscle tissues are such as skeletal, smooth, and cardiac. The three kinds of mature tissues are dermal, vascular, and ground tissues. The cells composing a tissue share a common embryonic origin. Clockwise from nervous tissue, LM × 872, LM × 282, LM × 460, LM × 800. For the linings of important organs to be protected, epithelial tissue helps cover … This type of membrane may be found encapsulating an organ, such as the kidney, or lining the cavity of a freely movable joint (e.g., shoulder). Tissue Membranes. The Four Types of Tissues. There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Epithelial Tissues . A mucous membrane, sometimes called a mucosa, lines a body cavity or hollow passageway that is open to the external environment. 0. There are four types of tissues dispersed throughout the body, as described below. Tissue types. There are two basic types of tissue membranes: connective tissue and epithelial membranes (Figure 3). The term tissue is used to describe a group of cells found together in the body. It is usually present in between the tissues throughout the body. Epithelial tissue provides a covering (skin, the linings of the various passages inside the body). Types of epithelial tissue : 1. Smooth muscle … Dense connective tissue … Cartilage is a type of supporting connective tissue. There may be various sub-tissues within each of the primary tissues. Figure 4.1 Overview of four tissue types: epithelial, connective, muscle, and nervous tissues. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body (Figure 4.2). A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body (e.g., skin), lines an internal body cavity (e.g., peritoneal cavity),  lines a vessel (e.g., blood vessel),  or lines a movable joint cavity (e.g., synovial joint). … Epithelial tissue : covers organs and body cavities, both external and internal, and controls the passage of substances between surfaces.
