principal tissues - these are epithelium‚ connective tissue‚ muscle and nerve tissue. The following paragraphs describe the main structural features‚ functions and sub-divisions of each type of tissue. EPITHELIUM Epithelium is characterised by closely packed cells and has very little extra-cellular material (ground substance or fibres). Cells are held together by means of desmosomes and tight junctions and form continuous sheets or layers which either cover the body’s outer surface (skin)

Across the board‚ the Total Current Assets is less than the previous year‚ more more than other earlier years. This could indicate that the company may have liquidized some of their assests within the year. Total Assests is greater than the

Slow-Oxidative (Type I) Muscle Fibres Shelby Daye Skeletal muscles are classified as striated and voluntary. They are found in muscles that maintain low-intensity contractions for long periods without fatigue. A single skeletal muscle cell is referred to as a muscle fibre. There are three types of muscle fibres found in the human skeletal muscle system including slow-oxidative fibres‚ fast-oxidative fibres and fast-glycolytic fibres. These three fibres are each defined by their biochemical capacities1

causes the contraction or shortening of skeletal muscle. Muscles contract and shorten and as a result of this they are responsible for the movement of the body. In order to have movement the body needs ligaments‚ tendons muscles‚ joints‚ bones and the neurotransmitter or message sent for movement. Skeletal muscles that produce movement occurs at any given joint‚ only one of the articulating bones will move. The point of articulation‚ or where the muscles and the bones connect‚ is known as a joint
