Cell differentiation is the process in which a generic embryonic cell develops into a specialized cell to do a particular job or function which has been triggered by the body or the actual cell itself by signals. The signals are sent to the cell receptor, which interprets the message through a signal transduction pathway. This pathway converts the message into something that the cell is able to recognize and understand. This is how a cell learns its functions and purpose. Cell differentiation allows the human body to produce more complex cells to then make specific types of tissues and organs. Without cell differentiation, no organism would be able to survive as cell differentiation is very vital for any living creature as it’s needed to make unique cells …show more content…
Muscle tissues are different from connective tissues as they’re specialised to be able to contract. They are stretched out and are often known as ‘muscle fibres’. Muscle tissues contain mitochondria which produce ATP. This helps the muscles to contract, so this is why muscle tissue contains more of this than the connective tissue as some of their functions are different from each other. There are three types of muscle cells; skeletal, cardiac and smooth muscle tissue. The skeletal muscles are attached to bones and cause contraction which is how bones are able to move. Cardiac muscle also contracts to force blood out of the heart and around the body. Smooth muscle is found in a number of organs, including the reproductive organs, the lining of the bladder, the digestive tract and the respiratory tract. The smooth muscle in the lining of the bladder contracts to force the urine out of the bladder. Other examples of contraction in muscle tissues are peristaltic movement to move faeces down the digestive system and the contraction of smooth muscle found in the trachea and bronchi which decreases the size of the air
