The Cell
This is a collection of cells that have similar structure and function together as a unit
What is tissue?
The celtral dogma of molecular biology states the DNA is transcribed into this
What is RNA
This occurs when a cell shrinks
What is Atrophy
This is one of the four common causes of cell injury.
What is hypoxia/trauma/toxin/pathogens
This is when oxygen is insufficient for normal function of our tissues
What is hypoxia
These are specialized intracellular structures that carry out specific functions to sustain life
What are organelles?
To maintain life and normal cell function, individual cells need to be in_______
What is homeostasis?
This occurs when a cells change from one type of functional cell to another type of functional cell
What is metaplasia
This type of tissue/cell can only survive a for 2-3 minutes without oxygen.
What are brain cells / nervous tissue?
This is when an inadequate blood supply to an organ or part of the body results in cellular injury
What is ischemia?
The plasma membrane is made up of this
What is a phospholipid bilayer?
All cells control or regulate the synthesis of proteins from DNA. This is called what?
What is Gene expression?
This is defined as disorderly growth.
What is dysplasia?
This organelle is the most susceptible to injury
What is mitochondria?
These are a bulge of the plasma membrane of a cell, characterized by a spherical, "blister-like" morphology.
What is a bleb?
This is how a cell controls which genes, out of the many genes in its genome, are “turned on”
What is gene regulation?
mRNA moves through ______ diffusion
What is Brownian diffusion?
This type of cellular adaptation can be either benign or malignant.
What is neoplasia?
This is the most common indicator of potentially reversible cellular injury; it involves cellular swelling
What is hydropic degeneration?
This is an area of necrotic tissue that commonly is invaded by bacteria. Smells terrible
What is gangrene?
This man discovered the cell
Who is Robert Hooke
These cells do not have nuclei.
What are erythrocytes?
This adaptation involves a loss of differentiation and a reversion to a more immature (undifferentiated) form
What is anaplasia?
These are the four fundamental underlying mechanisms of cellular injury (name at least 3)
What are ATP depletion, permeabilization of cellular membranes, disruption of biochemical pathways, and damage to DNA?
When a large number of cells in the area die; such as a MI
What is infarction?
