ego and the superego before they are given overt expression. The
permanently unconscious motivational cauldron of the mind. From the id originate all the drives that impel psychic
life. A "residue of countless egos" inherited from prior generations, the id is the amoral beast within us that seeks
only its own gratification through tension discharge. It is powered by the bodily instincts and is wholly irrational.
Analogous to the job of the imperialist and the industrialist, the job of the ego is to dominate it. The term id comes

internalizing behaviors -- behavior excesses displayed by students with emotional and behavior disorders in which actions are
directed inward (e.g., extreme
shyness, hypochondria).

internalizing problems -- psychological difficulties, such as anxiety or depression, that involve a focus on or within the self

internal working model -- a set of expectations derived from early caregiving experiences concerning the availability of attachment
figures, their likelihood of providing support during times of stress, and the self's interaction with those figures. Becomes a model, or a
guide, for all future close relationships.  On the basis of cognitive psychology,
Bowlby sees higher animals as needing a map or model
of the world in the brain, if they are successfully to predict, control, and manipulate their environment. In
Bowlby's environmental model,
telling us about the world, and an organismal model, telling us about ourselves in relation to the world. We carry a map of self, and
others, and the relationship between the two. Although primarily 'cognitive' in conception, the idea of internal working models is
applicable to affective life. The map is built up from experiences and is influenced by the need to defend against painful feelings. Thus an
anxiously attached child may have a model of others in which they are potentially dangerous, and therefore must be approached with
caution, while their self-representation may be of someone who is demanding and needy and unworthy to be offered security. The
relationship with a person's primary caregivers is generalized in internal working models, which leads to a distorted and incoherent
picture of the world, and one that is not subject to updating and revision in the light of later experience. This, in
Bowlby's eyes, is the
basis for transference, and the task of therapy is help the patient develop more realistic and less rigid internal working models.

Internet -- a global network of computers.

motor neurons.

abnormalities like
Klinefelter's, and hormonal causes such as adrenal hyperplasia, androgen insensitivity, testicular
feminization. (Traditionally if a boy had a penis of less than 2.5 cm long, he was made into a girl; if a girl had a clitoris of greater than
0.9 cm, it would be reduced, independent of the cause. Gender surgery was always done in the first two years, but current thinking is to
delay and make a more measured decision.) Sometimes referred to as
hermaphrodite.

intestinal malrotation -- twisting of the intestines so that they can become obstructed

intestinal motility dysfunction -- intestinal walls consist of layers of muscles which relax and contract in a coordinated fashion that
propels food from the
esophagus to the stomach and through the intestines to the anus. A motility disorder occurs when the
intestines don't contract and relax in a coordinated fashion. Symptoms may be difficulty swallowing, heartburn, gas, bloating, nausea,
vomiting, constipation, and diarrhea. These disorders may be associated with
irritable bowel syndrome, diabetes, gastroparesis
(paralysis of the stomach),
esophageal spasms, Hirschsprung's disease, chronic intestinal pseudo-obstruction, scleroderma,
and
achalasia.

intestinal pseudo-obstruction -- a rare condition with symptoms like those caused by a bowel obstruction or blockage. But no
blockage is found. Instead the symptoms are due to nerve or muscle problems that affect the movement of food, fluid, and air through
the intestines. This disorder can occur at any age, but occurs more often in young children and older adults. A
congenital and chronic
form is called
chronic intestinal pseudo-obstruction (CIP). Usually the cause is unknown, but sometimes it is caused by abdominal or
pelvic surgery,
lupus erythematosus, scleroderma, Parkinson's disease, infections, and certain medications. Symptoms are
cramps, abdominal pain, nausea, vomiting, bloating, and constipation.

intestines -- a segment of the alimentary canal extending from the stomach to the anus. It consists of two segments, the large and the
small. The
small intestine is divided into the duodenum, the jejunum, and the ileum. The large intestine consists of the cecum and
the
colon. The small intestine is grayish purple and about 1.5 inches in diameter; 20 -- 23 feet long in an average adult man. The large
intestine is a dark reddish color, and is roughly 5 feet long, on average. The intestines are covered with goblet cells which secrete
mucus which lubricates the passage of food along and protects the intestines from digestive enzymes. The small intestine secretes a
hormone called
secretin, which stimulates the pancreas to produce digestive enzymes. Most food products are absorbed in the small
intestine. The large intestine is responsible for absorption of water and excretion of solid waste.
