Tissue Types

Tissue Types

1. Epithelial

   • Epithelial Tissues protect the body from losing moisture, internal injuries and bacteria.
   • They come in two types: Covering/Lining Epithelium encases nearly all internal and external body surfaces, such as the outermost layer of the skin and other organs and the lining of lymph vessels and the digestive tract. Glandular Epithelium is responsible for the secretion of hormones and by-products such as stomach acid, sweat, milk, and saliva. 

2. Nervous

   • The nervous system is comprised of these nervous tissues. Nervous Tissues consist of: Neurons, the basic structure of the nervous system, each cell consisting of the cell body, dendrites, and axon. Neuroglia or glial cells help to provide functional support for the neurons, such as anchoring those neurons to blood vessels and insulating them.

3. Connective

   • Connective tissues tend to provide structural support to the body, serving a connecting function. They fill the open space between organs and tissues, and provides structural support as well as metabolic support for other tissues and organs. These tissues are made up of a scatter of cells contained within an extracellular matrix of fibrous proteins. Connective, unlike epithelial is not made of tightly compact cells.
   • Types Of Connective Tissue Loose: Adipose Tissue stores fat. Fibrous: Cartilage is comprised of tightly packed collagenous fibres. Mineralized: Bone contains collagen and calcium phosphate. This gives bones there firmness.

4. Muscle

   • Muscle tissues, differing from the other four stated in the mind map, are able to contract. They come in three types: Cardiac- Found in the heart, intercalated disk enable the cardiac muscle tissue to contract in such a way that it becomes a wave like action. Smooth- Smooth can be found lining the walls of blood vessels and organs like the digestive tract. Smooth Muscle cells are under involuntary control like cardiac muscle tissues. Each of these tissues have a single nucleus located in the centre of the tissue. Skeletal- Can be found attatched to bones, as the name implicates, and causes the movements of the body. These tissues are controlled both voluntary and involuntary.
