Connective tissue (CT) is one of the four types of biological tissue that support, connect, or separate different types of tissues and organs in the body.The other three types are epithelial, muscle, and nervous tissue.Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system the outer membranes, the meninges, that cover the brain and spinal cord are composed of connective tissue.onnective tissue (CT) is one of the four types of biological tissue that support, connect, or separate different types of tissues and organs in the body.
a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. Other types of bonds include metallic bonds and hydrogen bonding.
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. Ionic Bonds An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
