Which tissues work together to form muscles?

epithelial
muscular
connective
nerves

The right answers are : muscular  and connective tissues.

Muscular tissues:

Muscle tissue is an association of cells called muscle fibers, differentiated for contraction. The massive contraction of a set of fibers causes the movement of the tissues to which they are attached.

There are three muscle tissues:

*Skeletal muscle tissue is found mainly in locomotor muscles. He is innervated by the voluntary nervous system.

*Cardiac muscle tissue exists only in the myocardium. His rhythmic contraction is involuntary.

*The smooth muscular tissue composes the muscular tunics of the viscera and vessels. It contracts involuntarily in response to stimulation of the autonomic nervous system or secretion of hormones.

Connective tissue.

Connective tissue is one of four types of animal biological tissue that supports, binds, or distinguishes different types of tissues and organs from the body. Great discovery of the end of the twentieth century, 200 diseases all more orphaned than the other connective tissue are now listed. It originates in the mesoderm, at the time of gastrulation, during embryonic development.
