pe, stabilizing the joints, producing heat, maintaining good posture.Cardiac muscle are located in the heart. It usually contracts to create the heartbeat,but this is not under a voluntary control. This muscle contracts at a steady rate which is set by a heart’s pacemaker the certain nerves can speed or slow the pacemaker if it’s necessary.Skeletal are located in the muscles that is connected towards the bones. They are able to regulate their contraction and relaxation. They can sometimes contract in a specific response to the reflexes.Smooth muscle are located within the walls of hollow organs like the stomach and the other organs of gastrointestinal tract. it does not have any of the striations therefore they are in voluntary control -it has a involuntary innervation. All the muscle types specialised in movement. The differences between the muscles in skeletal muscle and cardiac muscle is that while being contradicted with muscles to make a heart beat they are not under voluntary control.  However, for smooth muscles they contract involuntarily in action due to being controlled by the autonomic part of nervous system.  The striated muscles between muscles can only be viewed only under a microscope for cardiac muscles and skeletal muscles and smooth doesn’t.Within the Cardiac muscles they consists of numerous of mitochondria and myoglobin whereas the other tissues have mitochondria as well.In addition to this, the three muscles tissues are found in various places for cardiac muscle they are found in the walls of the heart, but they appear to be striated under involuntary control.Muscle cells in the heartMuscle cells in the stomachMuscle cells in arm Each of the muscle tissues consists of these organellesMuscle tissues contains organelles which produces ATP during the aerobic respiration. This ATP is needed to contract the muscle tissues. Without mitochondria your muscle will not have the ability to contract. The significant role of mitochondria is to produce energy to the cells. ATP through the cell respiration regulates the cellular metabolism. As the muscle tissue has high energy requirement they require a force of gravity to produce heat and pumping the blood around the body to move the substances throughout the organs and produce movement of the muscles. This strong activity is functioned by organelles which is called mitochondria.   The cellular power plants change the glucose into adenosine triphosphate,  this molecule has the ability to store numerous amount of energy. The reason why muscle cells have numerous of mitochondria so they can quickly respond to the body movement.The four tissues have a similarity of numerous mitochondria.Muscle tissue contains a Endoplasmic reticulum which has a network of thin membranes that are located in the cytoplasm. The Rough ER consists of ribosomes. They are the transport system to the proteins. Cardiac muscle cells have numerous of cells needed to transportation for the proteins to maintain a proper function. The Endoplasmic reticulum role in the cells folds and transfers numerous proteins that will be carried towards the golgi body apparatus. Most proteins in glycoproteins move to the ER.  The Rough ER are usually covered by ribosomes where all proteins are together. Another organelle that muscle tissue has is a ribosomes which functions as a micro-machine to produce proteins. Ribosomes are made up of special proteins and nucleic acids. In ribosomes the amino acids are described as the heart of the protein production process. Ribosomes retain a certain structure to produce proteins.                               Connective tissueBlood connective tissue                          Bone connective tissue                     Connective tissue  structure performs a function to  support the body and to bind together or connect together all types of tissue. The tissues provide a mechanical framework which is (the skeleton) which is a significant role in this process. There are four sub-tissues in connective tissue. Adipose, blood, bone.In connective tissue they consists of three parts: matrix, fibers. Within the connective tissue there are main cell types in a fibroblasts which are secrete of the matrix are: collagen (fibrous protein), Elastin ( coiled protein which can be stretch), Reticular (another collagen that makes a network)Organelles are often organised in a matter of sub-units in a cell,but for the individual cells they are separately surrounded by their own lipid bilayers. Some organelles that connective tissue include:The golgi body apparatus is an organelle within the connective tissue which functions to adds carbohydrates to the proteins and  produce glycoproteins. They also transfer and modify the lipids which are stored. Mitochondria is an organelle which exists in connective tissue and are responsible for the production of ATP. Within each of the cells a chemical reaction releases energy from the glucose in mitochondria. In tissues and organs it is required for them to have a lot of energy  have numerous mitochondria in their cells.  Within the cells there are many organelles that function in removing any toxins. The organelle which is involved with this process of digestive and removal of toxins is lysosomes. Lysosomes are known as the organelles that contains a digestive enzymes. They are often specialised to perform a function in digesting excess or worn out organelles, and engulfing viruses. This membranous organelle is the largest organelle of the cell. ….Rough Endoplasmic Reticulum. …Smooth Endoplasmic Reticulum. …Ribosome. …Cilia. …Lysosomes.There the four types of components of connective tissues Type I collagen that make a fibers that are located within the most connective tissues with bones & ligaments, tendons;  the skin that has a high concentrations of the type I collagenType II collagen are made of fibers that are not really arranged comparing to  type I fibers. They are located in the cartilage.Type III collagen are made from fibers but these fibers are very narrow  than the specific type I. Type III collagen are from reticulin fibers in the organs they help  to arrange cells within organs.Type IV collagen are made up different networks that help to arrange the basement of membrane. tissuesEpithelial tissues covers the exterior and the interior body surfaces. The covering and the lining are located on the surface such as the skin and hide and the walls of the body cavities, cover all the organs and lining the blood vessels like (capillaries ,arteries and veins; heart.The walls of the alveoli in lungs are made from a layer of flattened epithelial cells.However, the glandular epithelium are forms of glands like sweat glands in the skin, salivary glands, goblet cells inside the lining of the respiratory tract mammary glands and intestinal glands.Epithelial tissue consists of cells that contain  organelles such as mitochondria which functions as the site of cellular respiration. For this tissue, they need more organelles for the protein secretion like Endoplasmic reticulum, ER. Endoplasmic reticulum is known as a 3D system of sheets such as membranes they are continuous with the nuclear envelope, but the membrane are surrounded by flattened sacs like cisternae.Epithelial cells in skin Epithelial cells in the small intestine microscopicComponents of Epithelial TissuesType IV collagen are forms of felt -like network fibers that give a basement membrane its tensile strength. The nidogen and perlecan are two small proteins that are related to the collagen network to laminin. There are numerous of components to basement membrane including the fibronectin.Similarities between epithelial tissues and connective tissues The similarities between connective and epithelial tissues is that both of their function is to work together to form organelles.  Both of the tissues have components, epithelial tissue have a little intracellular matrix whereas connective tissue have a large amount of intracellular matrix. As it is required for support and segregating tissues. These tissues function in a matter of protecting and advancing the cells.  Further in the human body they tend to be developed from the mesoderm. In terms of the location of the tissues they both differ in numerous of ways as they work in a conjunction with each other towards other tissues. The human body is composed of many systems functions to perform their function. Theses are organelles that exists in epithelial tissues The organelle nucleus is found within the epithelial tissue cells usually changes shape according to the cell structure.  The nucleus does this action for the epithelial cells structure to be very close together. In the epithelial cell it contains a appendages known as a cilia. This only occurs in the tissue function. The location that cilia is found in the epithelial tissue as it is found in the Throat.Nervous tissueNerve tissue are made from a spinal cord and brain is the central processing center for all stimuli. Peripheral nervous tissue contains nerves forms of nerve cells called neurons. The nerves are extend throughout the body from the tips of finger to internal organs. The  function of nerve tissue is so the senses conducts and transmit significant information across.Nervous tissue has two major cell types:Neurons can conduct the nerve impulses They are able to support cells like schwann cells that are located in the peripheral nervous system. They are able to form the myelin sheaths which are able to cover the neurons and the neuroglia or glial cells that exists in the brain and the spinal cord.Components of nerve tissue.Myelin is the coating of an axon. The white substance in Myelin surrounds the axon of the nerve cells. It often reacts as a electrically insulating layer.  The cells found in the neuroglia tends to increase the speed of the impulses amongst the axon in the neuronal fiber.Nervous tissue is the central and also the peripheral nervous system. It is composed of neurons and neuroglia cells.The brain is known as the center of the central nervous system. It is found in the skull.Organelles in nervous tissue.Peroxisomes and Endosomes are organelles that exists in the nervous tissue. Peroxisomes and Endosomes are found in everywhere in the cells. They are fundamental.  It is vital to have peroxisomes as it is required for proper brain development and function along with preventing any common diseases that could develop in the future. Whereas endosomes are specialised in sorting and transporting the materials from a cell surface and also transferring any materials from the golgi apparatus the lysosome.
