NR507. Advanced Pathophysiology

Chemicals secreted by cells - answer hormones
neurotransmitters
cytokines

Three Methods of Communication between cells - answer Gap junction
chemical secretion
Remote Signaling

remote signaling - answerchemicals secreted can travel near or far to a specific cell

chemical secretion - answercells secrete chemicals into the bloodstream

gap junction - answerA type of intercellular junction in animals that allows the passage
of materials between cells.

signal transduction - answerA series of molecular changes that converts a signal on a
target cell's surface to a specific response inside the cell.

cellular metabolism - answerall of the chemical reactions that are part of maintaining
cellular function

Anabolism - answerMetabolic pathways that construct molecules, requiring energy.

catabolism - answerMetabolic pathways that break down molecules, releasing energy.

anaerobic metabolism - answerThe metabolism that takes place in the absence of
oxygen; the principle product is lactic acid.

aerobic metabolism - answerThe cellular process in which oxygen is used to metabolize
glucose. Energy is produced in an efficient manner with minimal waste products.

temperature
stimulate nerve endings = pain

Antigen - answerlarge molecules that are foreign to the host

PAMP - answerpathogen-associated molecular pattern- molecular pattern on surface of
bacteria, viruses, and other microbes

DAMP - answerdamage-associated molecular pattern - proteins that are released from
human cells when they are damaged

PRR - answerPattern Recognition Receptors. Receptors that recognize PAMPs or
DAMPs

Diapedesis - answerpassage of blood cells (especially white blood cells) through intact
capillary walls and into the surrounding tissue

Chemotaxis - answerCell movement that occurs in response to chemical stimulus in the
direction of the Ag

the primary phagocytic WBCs - answerneutrophils and monocytes
