Epithelial
Squamous
Squamous cells have the appearance of thin, flat plates. The shape of the nucleus usually corresponds to the cell form and help to identify the type of epithelium. Squamous cells, for example, tend to have horizontal flattened, elliptical nuclei because of the thin flattened form of the cell. They form the lining of cavities such as the mouth, blood vessels, heart and lungs and make up the outer layers of the skin.
Simple Cuboidal
As their name implies, cuboidal cells are roughly square or cuboidal in shape. Each cell has a spherical nucleus in the centre. Cuboidal epithelium is found in glands and in the lining of the kidney tubules as well as in the ducts of the glands. They also constitute the germinal epithelium which produces the egg cells in the female ovary and the sperm cells in the male testes.
Simple Columnar
Columnar epithelial cells occur in one or more layers. The cells are elongated and column-shaped. The nuclei are elongated and are usually located near the base of the cells. Columnar epithelium forms the lining of the stomach and intestines. Some columnar cells are specialised for sensory reception such as in the nose, ears and the taste buds of the tongue. Goblet cells (unicellular glands) are found between the columnar epithelial cells of the duodenum. They secrete mucus or slime, a lubricating substance which keeps the surface smooth.
Glandular
Columnar epithelium with goblet cells is called glandular epithelium. Some parts of the glandular epithelium consist of such a large number of goblet cells that there are only a few normal epithelial cells left. Columnar and cuboidal epithelial cells often become specialised as gland cells which are capable of synthesising and secreting certain substances such as enzymes, hormones, milk, mucus, sweat, wax and saliva. Unicellular glands consist of single, isolated glandular cells such as the goblet cells. Sometimes a portion of the epithelial tissue becomes invaginated and a multicellular gland is formed. Multicellular glands are composed of clusters of cells. Most glands are multicellular including the the salivary glands.
Stratified
Where body linings have to withstand wear and tear, the epithelia are composed of several layers of cells and are then called compound or stratified epithelium. The top cells are flat and scaly and it may or may not be keratinised (i.e. containing a tough, resistant protein called keratin). The mammalian skin is an example of dry, keratinised, stratified epithelium. The lining of the mouth cavity is an example of an unkeratinisied, stratified epithelium.
CONNECTIVE
Aerolar
Fibrous connective tissue, loosely packed, to hold tissue layers together.
Adipose
Fatty tissue; type of loose connective tissue that stores energy, insulates and cushions the body.
Fibrous
Tissue composed of bundles of collagenous white fibers between which are rows of connective tissue cells.
Bone Tissue
Most rigid connective tissue, Internally supports body structures, very active tissue, heals much more rapidly than cartilage.
Cartilage Tissue
Dense, flexible tissue similar to bone tissue.
Blood Tissue
Constists of blood cells surounded by nonliving fluid matrix called plasma. funcion:transport vehicle for cardiovascular system, carrying nutrients, wastes, respiratory gases, and many other subs thru body.
Hemopoietic Tissue
Produces blood cells that are added to the circulating blood, removes worn out blood cells from the blood stream, red bone marrow, lymphatic tissue, yellow bone marrow.
MUSCLE
Smooth
Smooth muscle tissue is made up of thin-elongated muscle cells, fibres. These fibres are pointed at their ends and each has a single, large, oval nucleus. Each cell is filled with a specialised cytoplasm, the sarcoplasm and is surrounded by a thin cell membrane, the sarcolemma. Each cell has many myofibrils which lie parallel to one another in the direction of the long

Types of Tissue in the body: 1. Epithelial tissues - are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception. 2. Connective tissues - bind structures together, form a framework and support for organs and the body as whole, store fat, transport substances, protect…
TYPES OF TISSUE Charlotte Montgomery-Smith Epithelial Tissue • The sub types of Epithelial Tissue • Simple squamous- can be found in the lining blood vessels, alveoli of lungs and glomerular capsules in the kidneys. • Simple cuboidal- can be found in the kidney tubules and on the surface of the ovaries. • Simple columnar- can be found in the small intestine, large intestine, lining of the uterus, the lining of the uterine tubes and the gallbladder. • Pseudo stratified Columnar- the ciliated…
Types of Epithelial tissues Description Cuboidal epithelia is discovered in the glands, the lining of the kidney tubules and the ducts of the glands. Simple cuboidal cells are functioned to create eggs cells within a woman’s ovaries and sperm cells for men. Further to this, it’s tightly structured together with little space between them. It’s functioned to absorb, secrete and excrete substances. In the intestines the epithelial cell absorbs the nutrients throughout digestion. The epithelial cell…
gained in the Lecture folder materials. 1. List the 4 primary tissue types and give the general characteristics and functions of each one. Connective tissue is the most abundant and the most widely distributed of the tissues and its main function is to support and protect. Epithelial tissue covers the body surface and forms the lining for most internal cavities and its function is to protect, secrete, absorb, and filter. Nervous tissue includes skeletal, smooth and cardiac. They’re used in contracting…
Tissues Alice Christopher Unit 5 Tissues A tissue is made up of cells that have the exact function. The human body contains four basic types of tissue contributing to homeostasis by providing diverse functions including protection, support, communication and resistance to disease. The four main types are epithelial, connective, muscle and nerve. Epithelial Tissue There are two types: Simple Epithelial tissue and Compound Epithelial tissue. These are the tissues that covers the body’s surfaces…
Tissues Epithelial tissues Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the covering or lining of all internal and external body surfaces. Epithelial tissue that occurs on surfaces on the interior of the body is known as endothelium. Epithelial cells are packed tightly together, with almost no intercellular spaces and only a small amount of intercellular substance. Epithelial tissue…

Alexis Gutierrez Mr. Levings 17 September 2014 Tissue Essay There are many parts and components that make up the human body. The smallest parts that make up all the parts of the body are tissues. A tissue is a group of similar cells from the same origin that all carry out the same function. The four main types of tissues that make up our body are muscle cells, nerve cells, connective tissue, and epithelial tissue. These cells all have different functions and they all work together to perform…
