➖Epithelial tissues are the covering and protective tissues in the animal body.
➖Epithelial tissue covers almost all organs and cavities within the body.
➖Epithelial tissue also forms a barrier to keep different body systems separate.
➖Epithelial tissue cells are closely packed (as shown in the image given above) and form a continuous layer.
🍪𝗖𝗼𝗻𝗻𝗲𝗰𝘁𝗶𝘃𝗲 𝗧𝗶𝘀𝘀𝘂𝗲
➖Connective tissues are made up of the cells those are separated by non-living material, and known as an extracellular matrix.
➖This matrix could be either liquid or rigid.
➖Connective tissues are further divided as −
◆Fibrous connective tissue
◆Skeletal connective tissue and
◆Fluid connective tissue

➖Tendons are the example of fibrous connective tissue.
➖Bone is an example of a skeletal connective tissue.
➖Bone forms the framework and provide supports to the body.
➖Blood is an example of fluid connective tissue.
➖Blood has a fluid (liquid) matrix known as plasma.
➖In plasma, the red blood cells (RBCs), the white blood cells (WBCs), and the platelets are remaining suspended.
🍪𝗠𝘂𝘀𝗰𝘂𝗹𝗮𝗿 𝗧𝗶𝘀𝘀𝘂𝗲
➖Muscular tissue largely consists of elongated cells, and also known as muscle fibers.
➖The muscular tissue is accountable for the movements in our body.
➖The muscular tissue contains special proteins known as contractile proteins; and this protein helps in contraction and relaxation and supports free movement.
🍪𝗡𝗲𝗿𝘃𝗼𝘂𝘀 𝗧𝗶𝘀𝘀𝘂𝗲
➖The brain, spinal cord, and nerves all are composed of the nervous tissue.
➖Cells of the nervous tissue are extremely particular and sensitive for being stimulated and then transmitting the stimulus swiftly from one place to another within the body.
➖The cells of nervous tissue are known as nerve cells or neurons.

➖Nerve impulses allow us to move our muscles whenever we want to do so.
