Types of Tissue
Cell Differentiation
Epithelial Tissue - The cells of epithelial tissue
pack tightly together and form continuous
sheets that serve as linings in different parts
of the body. Epithelial tissue serve as
membranes lining organs and helping to keep
the body's organs separate, in place and
protected. Some examples of epithelial
tissue are the outer layer of the skin, the
inside of the mouth and stomach, and the
tissue surrounding the body's organs.
Connective Tissue - There are many types of
connective tissue in the body. Generally
speaking, connective tissue adds support and
structure to the body. Most types of connective
tissue contain fibrous strands of the protein
collagen that add strength to connective
tissue. Some examples of connective tissue
include the inner layers of skin, tendons,
ligaments, cartilage, bone and fat tissue. In
addition to these more recognizable forms of
connective tissue, blood is also considered a
form of connective tissue.
Muscle Tissue - Muscle tissue is a
specialized tissue that can
contract. Muscle tissue contains the
specialized proteins actin and myosin that
slide past one another and allow
movement. Examples of muscle tissue
are contained in the muscles throughout
your body.
Nerve Tissue - Nerve tissue contains two
types of cells: neurons and glial
cells. Nerve tissue has the ability to
generate and conduct electrical signals in
the body. These electrical messages are
managed by nerve tissue in the brain and
transmitted down the spinal cord to the
