They are formed by the polymerisation of tubulin. Tubulin consists of a alpha-beta heterodimer. They are involved in cell division (12) 5. A loose fibro-fatty connective tissue. It forms the bottom layer of the skin (10) 6. A dense fibroelastic connective tissue. It forms the middle layer of the skin (6) 8. Found in connective tissue, basement membrane, bone etc. It consists of 3 alpha chains wound around each other to form a triple helical structure - this helps to resist stretching forces (8) 9. Covers the outside of the body and lines organs, vessels and cavities. They are tightly packed together in sheets and lay on top of a basal lamina/membrane (10, 6) Down 2. Allows for the movement of small molecules between adjacent epithelial cells. Usually just water and small soluble ions (3, 8) 3. A stratified squamous keratinised epithelium that forms the first layer of skin. Also has hair follicles, sebaceous glands and sweat glands (9) 4. Involved in cell-cell adhesion by linking to intermediate microfilaments within the cytoskeleton (10) 7. Synthesised by epithelial cells. It is a heterotrimer - made up of 3 chains - alpha, beta, gamma. Contains collagen. Contributes to organising the matrix and helping cells to attach to it (7) 10. Found in connective tissue and blood vessels. It consists of tropoelastin chains that have been crosslinked. It confers resilience, i.e. elasticity (7)
