Multicellular
Generic name for an organism which has more that one cell
Tissue
Name for a group of cells which have the same structure and function, working together
Organ
Name for several tissues working together to perform a specific function
Neuron

Levels of organisation
1. Chemical level. 2. Cellular level. 3. Tissue level. 4. Organ level. 5. System level. 6. Organism level.
Skeletal muscle
Attached to the skeleton. Capable of contracting and relaxing. Voluntary control
Smooth muscle
Located in walls of hollow visceral organs, except the heart, appear spindle-shaped and are also under involuntary control
Cardiac muscle
Walls of the heart, appear striated and are under involuntary control
Skeletal (striated)
Under voluntary control. Striated appearance is due to protein fribrils contained within the fused muscle cells
Smooth
Contracts involuntarily and forms the walls of many hollow organs
Cardiac
Only found in the heart
Epithelial tissue
Sit on basement membrane made of collagen and protein
Squamous epithelium shape
Flattened cells on a basement membrane
Squamous epithelium location
Form walls of aveoli in the lungs and line the bowman's capsule of the kidney nephron
Cuboidal epithelium shape
Cubed shape on basement membrane
Cuboidal epithelium location
Found in kidney nephron
Columnar epithelium shape
Column shape on basement membrane. Cells have cilia if lining a tube which substances such as eggs will move through. They are then known as ciliated columnar epithelial cells
Columnar epithelium location
Found lining trachea and the ovaries
Connective tissue function
Binds and supports tissues
Connective tissue structure
Consists of cells, elastic and collagen fibres
Organ system
A group of organs working together with a particular role
