TISSUES Meaning and
Definition
-
Tissues refer to a group or collection of similar cells that work together to execute specific functions in an organism. These cells share a common embryonic origin, structure, and function. Tissues are the building blocks of organs, which are further organized systems serving larger and more complex roles in the body.
There are four main types of tissues in multicellular organisms: epithelial, connective, muscle, and nervous tissues. Epithelial tissues cover the surfaces of the body, lining structures such as the skin, organs, and blood vessels. These tissues act as protective barriers, regulating the exchange of substances. Connective tissues provide support and connect different parts of the body, including bones, tendons, ligaments, and cartilage. They are made up of cells embedded in an extracellular matrix. Muscle tissues enable movement and contraction, and are responsible for bodily movements such as walking and breathing. Lastly, nervous tissues consist of specialized cells called neurons, which transmit electrical signals throughout the body, allowing for communication and control.
By working together, tissues ensure the proper functioning and maintenance of organs and organ systems. Their precise arrangement and combination play a vital role in an organism's survival and well-being.

Etymology of TISSUES
The word "tissues" originated from the Latin word "tessera" meaning "a small piece" or "a square". In medieval Latin, "tissu" referred to a woven cloth. The word was later introduced into English around the 14th century to describe a fine woven cloth or fabric. As time progressed, the term began to be used to refer to delicate pieces of material, such as those used for wrapping or cleaning. Eventually, "tissue" evolved to its current meaning, denoting a thin, soft paper used for personal hygiene or other purposes.
