Areolar Tissue is loose connective tissue that consists of a meshwork of collagen, elastic tissue, and reticular fibres - with many connective tissue cells in between the meshwork of fibres. Areolar tissue binds skin to the muscles beneath. This loose connective tissue also forms a link between organs - while also enabling a high degree of movement between adjacent body parts. The key functions of areolar tissue can be summarised as providing: a) Support b) Strength, and c) Elasticity. Nervous Tissue: Nervous tissue makes the nervous system and is composed of specialized cells called neuron. A neuron can be divided into two distinct parts, viz. head and tail. The head is somewhat star-shaped and contains nucleus and some other cell organelles. This is called cyton. There are numerous hair-like outgrowths coming out of the cyton. These are called dendrites. The tail ends in axon terminals. Dendrites receive the nerve impulse, while axon relays the nerve signals.
