Different Types of Tissues by Mind Map: Different Types of Tissues

1. Connective tissue - underlies and supports other tissue types.

1.1. Proper: Loose; dense (regular, irregular) connective tissue Embryonic: Mesenchymal; mucous connective tissue Specialized: Cartilage; adipose; bone; blood

1.1.1. based upon two characteristics: the composition of its cellular and extracellular components and its function in the body. Tissues are either classified as proper, embryonic, or specialized.

2. Nervous tissue - transmits and integrates information through the central and peripheral nervous systems.

2.1. Neurons Function: transmission of electrical impulses Structure: soma (cell body), axons (transmit impulses away from soma), dendrites (transmit incoming impulses) Organization: ganglia (PNS) and nuclei (CNS)

2.2. Glia Function: support and nourish neurons Astrocytes: support synapses, form a protective barrier around blood vessels Oligodendrocytes: insulate axons and increase impulse projection in the CNS Schwann cells: oligodendrocytes equivalents in the PNS Microglia: defend the nervous system

3. Muscle tissue - contracts to initiate movement in the body.

3.1. Extensible, elastic, contractile, organized into bundles

4. Epithelial tissue - creates protective boundaries and is involved in the diffusion of ions and molecules.

4.1. Highly cellular, function as receptors, form a barrier, minimal extracellular matrix, avascular, innervated,
