Autoimmune Disorder

A disorder in which the immune system attacks the body’s own cells.

B Cell

A type of immune cell that fights intruders by producing antibodies.

Cognitive Theory

Theory that states a person identifies an emotion based on a cognitive assessment of the stimulus situation.

Congenital Insensitivity to Pain

A condition present at birth in which the person is insensitive to pain.

Cortisol
