Clockwise from nervous tissue, LM × 872, LM … Four Types of Tissue Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. It has semisolid consistency and consists of reticular cells, monocytes, and lymphocytes. Figure 1 illustrates how tissues … This tissue is of two types as. Epithelial tissue; Connective tissue; Muscular tissue; Nervous tissue. Neuroglia play an essential role in supporting neurons and modulating their information propagation. Epithelial tissue … They help in the contraction and relaxation of man organs like lungs, stomach, uterus, etc. It is made of fibroblasts, mast cells, macrophages, and fat cells. Some epithelial cells secrete mucous. These cells include fibroblasts, fat cells, mast cells, and also white blood cells like the macrophages, plasma cells, etc. True | False. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. (Areolar tissue, adipose tissue). Created by. As the name indicates, these are present in the heart. are spindle or cone-shaped in structure. Based on the shape of lower layer cells, the epithelium is again differentiated as stratified squamous epithelium, stratified cuboidal epithelium, columnar stratified epithelium, and pseudostratified columnar epithelium. Other movements are involuntary. Collectively, organ systems work together to for a organism for function properly. they are under the control of our will. Connective tissue is diverse collection of tissues that support and connect other tissues, but also have protective functions. 2. The blood cells include. A disruption of the structure is a sign of injury or disease. Organs are organized into organ systems to perform functions. Supply of oxygen and nutrient to all the body. For example, the epithelial cells of the small intestine releases digestive enzymes. They are controlled by the brain. Further, the upper layer cells might be keratinized, dehydrated to protect from heat, microbes, wear and tear, chemicals, etc. If there is any damage to them in between, it can lead to loss of their function forever. They are; nerve, epithelial, connective, and muscle. Neuroglial tissue is a binding tissue around the neurons. There are two types of connective tissue: Loose connective tissue holds structures together. The blood cells include, The plasma consists of 90% water, and remaining includes, It is harder and stronger than prior tissue types. Epithelial tissue, also referred to as epithelium, refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. This cilium moves the mucus towards the throat. Each tissue type also has sub-classifications. Some epithelia often include structural features that allow the selective transport of molecules and ions across their cell membranes. This muscle helps to pump blood by the heart.

Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body. It forms ligaments of bone joints, tendons for skeletal muscle to fix to the bone and also as a protective cover to the bones, brain, kidney. This connective tissue is of different types as. Cells are cuboidal or columnar in a relaxed state. The Four Types of Tissues. Stratified epithelium (multiple layers of cells), 45%) and plasma (55%). Figure 4.2. Some Rights Reserved. But when there is load, they stretch and become flat to accommodate the substance (urine). Nervous Tissue: This is a special kind of tissue which is responsible for receiving, transmitting and … But the difference is, they have branches. They are controlled by the brain. Note that there are also subclassifications of these, and also a couple other general classifications. Such changes can be detected through histology, the microscopic study of tissue appearance, organization, and function. They are voluntary i.e. The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous. Liquid connective tissue (examples of tissue is blood, Electrolytes (Sodium, potassium, magnesium, calcium, etc), Nutrients like glucose, amino acids, lipids, Defense against disease-causing pathogens. Epithelial tissue : covers organs and body cavities, both external and internal, and controls the passage of substances between surfaces. Organs are organized into organ systems to perform functions. Homeostasis. Examples: blood; bone; adipose (fat); cartilage. They help in moving from one place to another. Muscle cells are excitable, meaning they generate a current when stimulated. Connective tissue… The cells in these tissues are widely dispersed from each other in a matrix (substance) which has fibers. The cells in the lower layers continually divide pushing those in upper layers towards the surface. They also have bands or striation along the length. These are of many types like adipose tissues, reticular tissue, etc. A tissue is a group of similar cells that carry out a specialized function. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. In the trachea, they have cilia on their free surface. Terms in this set (4) Epithelial.
