6 Types of tissues: epithelial and muscular

When similar cells group together and perform a function, they form a tissue. Tissues are formed by groups of specialised cells. There are different types of tissue.

The four types of tissues in multicellular organisms are epithelial tissue, muscular tissue, connective tissue and nervous tissue.

Epithelial tissue covers body surfaces and lines organs. They are also the main tissue in glands. Their functions include absorbing, secreting and transporting substances.

Muscular tissue is made up of elongated muscle cells in parts of the body that move, such as the heart. Their function is to contract and relax in order to produce movement.

• Connective tissue supports, protects and maintains the form of the body and its organs and transport nutrients between tissues and organs. For example, bone and cartilage.

• Nervous tissue coordinates and controls many of the body’s activities. It is found in the brain, spinal cord and nerves.

2 Write a definition of nervous tissue and connective tissue in your notebook.
