Ch 1/2
The body part lateral to your nose
What are the ears?
The organelle where mRNA is made into proteins
What is a ribosome?
The genetic instructions for the synthesis of proteins
What are genes?
The cell type responsible for storing and synthesizing lipids
What are adipocytes?
The most superficial layer of the dermis, primarily made of areolar tissue
What is the papillary layer?
The physiological change that leads to more change in the same direction
What is a positive feedback loop?
The definition of osmosis
What is the movement of water from a high concentration to low concentration?
The nitrogenous base NOT found in DNA
What is uracil (U)?
The striated, involuntary tissue
What is cardiac muscular tissue?
The stratum corneum is made up of this protein
What is keratin?
The collective term for all decomposition reaction occuring the human body
What is catabolism?
The ability of a solution to alter how a fluid moves in or out of a cell
What is tonicity?
The process of turning genes on and off depending on what protein needs to be made
What is gene regulation?
The specific tissue that secretes mucus and propels it with cilia.
What is pseudostratified columnar epithelium?
The muscle whose contraction causes goosebumps in response to fear or the cold
What is the piloerector muscle?
The minimum energy required for a reaction to occur that is lowered by the use of enzymes
What is activation energy?
The difference in the amount of solutes across a membrane (or two areas)
What is a concentration gradient?
The process through which DNA is read and copied into mRNA
What is transcription?
The cell and stubstance that promotes vasodilation during inflammation
What is mast cells and histamine?
The tube that holds hair, which extends into the subcutaneous layer
What is a follicle?
The condition characterized by a low concentration of protons in the blood
What is alkalosis?
The response of a red blood cell in a hypotonic solution
What is swell/burst?
The entire process of protein synthesis
What is...
DNA is unzipped; complimentary bases are added to create a strand of mRNA; mRNA leaves the nucleus and travels to a ribosome on the rough ER; at ribosome, mRNA is turned into several amino acids; strings of amino acids link to become proteins in the rough ER
The steps (or phases) of wound healing
What is...
Inflammation (blood pools into wound, vasodilation, immune cells, clotting proteins, and more blood arrives) -> blood clot forms, as does scab -> white blood cells digest tissue debris -> blood clot is removed but scab remains -> new capillaries and collagen fibers enter -> epithelium regenerates, dermis undergoes fibrosis -> remodeling?
To sweat with wetness on the skin
What is diaphoresis?
