Cell and tissue types

http://en.wikipedia.org/wiki/Connective_tissue
Connective tissue (CT) is a fibrous tissue and the most diverse tissue.^[1] It is one of the four traditional classes of tissues (the others being epithelial, muscle, and nervous tissue). CT is found throughout the body.
The special CT subtype includes cartilage,bone, adipose tissue, blood, hematopoietic tissue (tissue that makes blood cells), and lymphatic tissue, as well as the most abundant protein in mammals, Type-I collagen, which makes up about 25% of the total protein content of the mammalian body.

http://en.wikipedia.org/wiki/Muscle_tissue
Muscle tissue is one of four basic biological tissues present in animals. It is a soft tissue that composes muscles.

http://en.wikipedia.org/wiki/Nervous_tissue
Nervous tissue is the main component of the nervous system - the brain, spinal cord, and nerves-which regulates and controls body functions. It is composed of neurons, which transmit impulses, and the neuroglia cells, which assist propagation of the nerve impulse as well as provide nutrients to the neuron.
 
http://en.wikipedia.org/wiki/Epithelium
Epithelial tissues line the cavities and surfaces of structures throughout the body, and also form many glands. Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport and detection of sensation. In Greek "epi" means, "on, upon," and "thele" meaning "nipple".


http://en.wikipedia.org/wiki/Neuron
A neuron ( /ˈnjʊərɒn/ newr-on; also known as a neurone or nerve cell) is an electricallyexcitable cell that processes and transmits information through electrical and chemical signals. A chemical signal occurs via a synapse, a specialized connection with other cells. 
 
http://en.wikipedia.org/wiki/Neuroglia 
Glial cells, sometimes called neuroglia or simply glia (Greek γλία, γλοία "glue"; pronounced in English as either /ˈɡliːə/ or /ˈɡlaɪə/), are non-neuronal cells that maintainhomeostasis, form myelin, and provide support and protection for neurons in the brain, and for neurons in other parts of the nervous system such as in the autonomic nervous system.
Microglia -  are specialized macrophages capable of phagocytosis that protect neurons of the central nervous system.
Macroglia 

• CNS: Astrocytes ("star", many functions, blood-brain barrier, ion homeostasis, nutrient support), Oligodendrocytes ("few branches", insulate axons), Ependymal cells, Radial glia, 

• PNS: Schwann cells, Satellite cells, Enteric glial cells
