Nervous Tissue The nervous tissues are specialized with no intercellular space. They are found in the brain, spinal cord, and nerves. These are the main components of the nervous system. The nervous system function to regulate and controls bodily functions. The nervous system consisting two parts- Central Nervous System and the Peripheral Nervous system (We will read about it in a separate post) Functions of Nervous Tissue These tissues are responsible for the coordination and controlling of many body activities by stimulating muscle contraction, creating awareness of the environment, and…

Muscular Tissue
Muscular Tissue The Muscle tissue is soft and it makes different types of muscles in animals, which gives the ability of muscles to contract. Muscular tissues are also referred to as myopropulsive tissue. Muscular tissues are formed during embryonic development by the process of myogenesis. The muscle tissues are mesodermal in origin except for the ciliary muscles of the eyes which are of ectodermal origin. The study of Muscles is called Myology. The muscle cells are elongated, slender, and spindle-shaped, fiber-like cells. The muscle tissue contains contractile proteins called actin…

Connective tissues The term connective tissue was introduced in 1830 by Johannes Peter Muller. The tissue was already recognized as a distinct class in the 18th century Connective tissues are the most abundant and widely distributed tissues of complex animals. These are mesodermal in origin. They perform the special function of linking and supporting and protecting other tissues/organs of the body. Features of Connective tissues: The connective tissues have variations from soft connective tissues to specialized types like cartilage, bone, adipose, and blood. In All connective tissues, the cells secrete…

Epithelial tissue The term “epithelium” was introduced by Frederic Ruysch in 1703. Epithelium tissue is made up of one or more layers of cells that are compactly arranged with a little intracellular matrix. Important features of Epithelial tissue: The Epithelial tissues line the external surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. It is also known as covering tissue. All glands are made up of epithelial cells. Functions of epithelial cells include secretion, selective absorption, protection, Transcellular…

Classification of Animal Tissues Animal Tissues In multicellular animals, a group of similar cells along with intercellular substances perform a specific function. Such an organization is called tissue. The tissues arise from the undifferentiated cells of Primary Germ Layers i.e. Ectoderm, Mesoderm, and Endoderm. Features of tissues: These tissues form an organ like – the stomach, heart, and kidneys by organizing themselves in specific forms. These organs together form organ systems like the digestive system, respiratory system, etc. The study of tissues is called Histology. The English word ’tissue’ is…
