Fusion

    The union and integration of the instincts and drives so that they complement each other and help the organism to deal effectively with both internal needs and external demands.

RELATED TERMS
--------------------------------------

Integration
The useful organization and incorporation of both new and old data, experience, and emotional capacities into the personality. Also refers to the organization and amalgamation of functions at various levels of psychosexual development.

Drives
A state of internal activity of an organism that is a necessary condition before a given stimulus will elicit a class of responses; e.g., a certain level of hunger (drive) must be present before food will elicit an eating response.

Complement
A series of serum proteins involved in the mediation of immune reactions. The complement cascade is triggered classically by the interaction of antibody with specific antigen.

Organism
A living thing, such as an animal, a plant, a bacterium, or a fungus.

Fusiform aneurysm
A vascular outpouching shaped like a spindle. A fusiform widening of an artery or vein. An aneurysm is a localized widening (dilatation) of an artery, vein, or the heart. At the area of an aneurysm, there is typically a bulge and the wall is weakened and may rupture.

Fusimotor Neuron
Motor neurons which activate the contractile regions of intrafusal muscle fibers, thus adjusting the sensitivity of the muscle spindles to stretch. Gamma motor neurons may be ""static"" or ""dynamic"" according to which aspect of responsiveness (or which fiber types) they regulate. The alpha and gamma motor neurons are often activated together (alpha gamma coactivation) which allows the spindles to contribute to the control of movement trajectories despite changes in muscle length.
