Tissue

A collection of specialized cells and cell products that performs a specific function.

There are four types of tissues

The four types of tissues are: Epithelial Tissue, Connective Tissue, Muscle Tissue, and NeuralTissue.

The Four Types of Tissues

Functions, Classifications, Specialization, and where they're found.

The epithelial tissue includes the surface of your skin, covers every exposed surface of the body. It also forms the surface of the skin and line the digestive, reproductive, and urinary tracts. Covers surfaces and line passageways.

  • Functions include: Providing Physical Protection, Controlling Permeability, Providing Sensation, and Producing Specialized Secretions.
  • Classifications include: the cell shape, the number of cell layers between the base and the exposed surface of epithelium.
  • Specializations include: The movement of fluids over the epithelial surface, providing protection and lubrication. The movement of fluids through the epithelium, to control permeability. The production of secretions that provide physical protection or act as chemical messengers.

The connective tissue makes up some of the epithelial tissue, other connective tissues include bone, fat, and blood, which provide structure, store energy reserves, and transport materials throughout the body. It supports weight and interconnects parts of the body.

  • Functions include: Responsible for providing structural support for tissues and organs, which is important for maintaining the body, organs, and tissues.
  • Classifications include: Connecting tissues properly, fluid connective tissues, and supporting connective tissues.

The muscle tissue is specialized for contraction. They possess organelles and properties distinct from those of other cells. There are three types of muscle tissues: skeletal muscle, cardiac muscle, and smooth muscle.

Functions include: Skeletal- forms the large muscles responsible fro gross body movements and locomotion. Cardiac- found in the heart and responsible for the circulation of blood. Smooth- found in the walls of visceral organs and a variety of other locations, where it provides elasticity, contractility, and support.

Classifications include: movement of bones, allow motion and heat production.

The neural tissue, also known as Nervous Tissue, is specialized for the conduction of electrical impulses from one region of the body to another. 98% of the neural tissue in the body is concentrated in the brain and spinal chord, which are the control centers of the nervous system.

Functions include: Sensory input, Integration, Controls of Muscles and Glands, Homeostasis, Mental activity.

Classifications include: supportive cells, our consciousness levels, thought process, electrical impulses.
