There are basically two types: physical ( The basic unit of all nervous tissue is the The third class of tissues includes those contributing to the body’s support and A fourth class of tissues includes reproductive tissues, hemopoietic tissues, and tissue fluids. The most important reproductive tissues are the gonads (ovaries and testes), which produce the gametes (eggs and sperm, respectively). Hemopoietic tissues produce the cellular components of the blood. Among the important tissue fluids are lymph, This article was most recently revised and updated by

• A tissue is a group of cells with the same origin that serve a similar function. • Tissues are found in animals and plants. • The four main types of animal tissues are connective, nervous, muscle, and epithelial tissues. • The three main tissue systems in plants are the epidermis, ground tissue, and vascular tissue. Animal Tissues Muscle is one of the types of animal tissue. Dlumen / Getty Images There are four basic tissues in humans and other animals: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. The embryonic tissue (ectoderm, mesoderm, endoderm) from which they derive sometimes varies, according to species. Meristematic Tissue Actively dividing cells are meristematic tissue. This is the tissue that allows a plant to grow. The three types of meristematic tissue are apical meristem, lateral meristem, and intercalary meristem. Apical meristem is the tissue at stem and root tips that increases stem and root length. Lateral meristem includes tissues that divide to increase the diameter of a plant part. Intercalary meristem is responsible for the formation and growth of branches. Permanent Tissue Permanent tissue encompasses all cells, living or dead, that have stopped dividing and maintain a permanent position within a plant. The three types of permanent tissue are simple permanent tissue, complex permanent tissue, and secretory (glandular) tissue. Simple tissue is further divided into the parenchyma, collenchyma, and sclerenchyma. Permanent tis...

Recall that tissues are groups of similar cells group of similar cells carrying out related functions. These tissues combine to form organs—like the skin or kidney—that have specific, specialized functions within the body. Organs are organized into organ systems to perform functions; examples include the circulatory system, which consists of the heart and blood vessels, and the digestive system, consisting of several organs, including the stomach, intestines, liver, and pancreas. Organ systems come together to create an entire organism. Epithelial Tissues Epithelial tissues cover the outside of organs and structures in the body and line the lumens of organs in a single layer or multiple laye...

Eschrichtius robustus) breaching. In size animals are outdone on land by plants, among whose foliage they may often hide. In contrast, the photosynthetic algae, which feed the open oceans, are usually too small to be seen, but marine animals range to the size of whales. Diversity of form, in contrast to size, only impinges peripherally on human awareness of life and thus is less noticed. Nevertheless, animals represent three-quarters or more of the species on Earth, a diversity that reflects the flexibility in feeding, defense, and reproduction which Animals move in pursuit of food, mates, or refuge from predators, and this movement attracts attention and interest, particularly as it becomes apparent that the behaviour of some creatures is not so very different from

Animal Tissue In animal tissues, there is a cytoplasmic NADP+-linked isocitric dehydrogenase (ICD), which is not associated with the mitochondrial NAD+-linked ICD or other enzymes of the TCA cycle. From: Clinical Biochemistry of Domestic Animals (Sixth Edition), 2008 Related terms: • Virus • In Vitro • Therapeutic Procedure • Patient • Tissues • Human Tissue Animal and plant tissues are usually prepared for elemental analysis by destruction of the organic matrix by oxidation, either in a furnace (dry ashing) or by the use of oxidizing acids (wet ashing). The two methods have similar outcomes in most respects, except that there is a tendency for volatile elements such as As and Se and even Cd to be lost during dry ashing, especially if the temperature is allowed to rise above 500°C. The normal outcome is for the elements to be nebulized from a dilute solution of hydrochloric acid. Matrix effects are not usually troublesome in this sector, although some materials high in calcium, potassium or phosphorus may require special attention. Figures 9 and 10 show the applicabilities of ICPMS and ICPAES for plant material. Concentrations of elements in animal tissues are broadly similar, although there are contrasts in certain cases.

Extracellular fluids contain large amounts of SCN −, and it is concentrated by certain types of ...

A tissue is a group of cells connected to each other that collectively perform similar functions in an organism. All contents of the body including structures and various organs are made of tissues. The animal body comprises four basic types of tissues, all of which vary in their origin and function. They are: • Epithelial Tissues: Made up of tightly packed cells layer together, epithelial tissues line the body surface. Their functions include protection, absorption, and secretion. Epithelial tissues can be found in the lining of the mouth and nose, digestive system lining, and the skin. • Muscle Tissues: These are of three types, smooth • Nervous Tissues: Made up of neurons (nerve cells in the brain), these tissues form the entire nervous system, including the spinal cord and the brain. • Connective Tissues: Made of various cells that are involved in lending support to the body, connective tissues are namely the fat, bone, blood and cartilage in an animal body. (Image will be uploaded soon) Epithelial Tissues These tissues form the lining of body surfaces and also account for glands. The cells along these tissues are tightly connected to each other. The epithelium does not contain blood vessels and hence depends on the other connective tissues to derive its nutrients and other essentials. It is found along the edges of the organs and has two prominent surfaces, namely, the apical surface which is on the exterior and lies open to the body cavity, and the basal surface whic...
