inferiority complex unconscious feelings of inadequacy, producing shyness or timidity or, as a compensation, exaggerated agressiveness and expression of superiority; based on Alfred Adler's concept that everyone is born with a feeling of inferiority stemming from real or imagined physical or psychological deficiency, with the manner in which the inferiority is handled determining behavior.

primary complex
1. the combination of a parenchymal pulmonary lesion (Ghon focus) and a corresponding lymph node focus, occurring in primary tuberculosis, usually in children. Similar lesions may also be associated with other mycobacterial infections and with fungal infections.
2. the primary cutaneous lesion at the site of infection in the skin, e.g., chancre in syphilis and tuberculous chancre.
QRS complex a group of waves seen on an electrocardiogram, representing ventricular depolarization. Called also QRS wave. It actually consists of three distinct waves created by the passage of the cardiac electrical impulse through the ventricles and occurs at the beginning of each ventricular contraction. In a normal surface electrocardiogram the R wave is the upward deflection; the first downward deflection represents a Q wave and the final downward deflection is the S wave. The Q and S waves may be extremely weak and sometimes are absent.

One abnormality of the QRS complex is increased voltage resulting from enlargement of heart muscle, which produces increased quantities of electric current. A low-voltage QRS complex may result from toxic conditions of the heart, most commonly from fluid in the pericardium. Pleural effusion and emphysema also can cause a decrease in the voltage of the QRS complex.
VATER complex an association of congenital anomalies consisting of vertebral defects, imperforate anus, tracheoesophageal fistula, and radial and renal dysplasia.
ventricular complex the Q, R, S, and T waves of the electrocardiogram, representing ventricular electrical activity. See also atrial complex.

Gol·gi ap·pa·ra·tus

a membranous system of cisternae and vesicles located between the nucleus and the secretory pole or surface of a cell; concerned with the investment and intracellular transport of membrane-bounded secretory proteins, and the synthesis of polysaccharides and glycoproteins.

Golgi apparatus

A network of stacked membranous vesicles, present in most living cells, that stores and modifies proteins and other macromolecules and transports them within the cell or excretes them from the cell. Also called Golgi body, Golgi complex.

Golgi apparatus

A collection of stacked, flattened, cup-shaped sacs situated in the CYTOPLASM of cells near the nucleus and concerned with the movement of materials within the cell. The Golgi apparatus receives protein-containing vesicles from the endoplasmic reticulum, glycosylates them, sorts them into groups for different locations and transports them to other parts of the cell or to the cell membrane for export. (Camillo Golgi, 1843–1926, Italian microscopic anatomist).

Golgi apparatus



a series of cell ORGANELLES consisting of a stack of membrane-lined vesicles called CISTERNAE, first described by Camillo Golgi in 1898 but only clearly defined from studies with the ELECTRON MICROSCOPE. See Fig. 178 . The membranes of the Golgi apparatus are produced from vesicles pinched off from the ENDOPLASMIC RETICULUM and secretory vesicles are formed by the apparatus which move to the periphery of the cell and may carry out EXOCYTOSIS. The apparatus is thought to have a storage role as well as enabling the assembly of simple molecules into more complex ones, for example, the packaging of carbohydrates and proteins into glycoprotein.

This hypothesis offers several possible scenarios: (1) Gd-IgA1-producing B-cell-specific proliferation and survival are enhanced during mucosal infections, (2) B-cell signaling is altered and directly regulates expression and activity of specific glycosyltransferases, and (3) there is a direct signaling effect on the function of the Golgi apparatus in IgA1-producing cells that increases synthesis of Gd-IgA1.
