specificity
Which is NOT true of the cytoskeleton?
it includes peroxisomes and proteasomes
Which of the following are true of the cell? Select all that apply.
1: Proteins carry out the functions of the cell membrane
2:Lysosomes are the digestive system of the cell
3:Microfilaments are thin, threadlike cytoplasmic structures
Which are true of the cell membrane? Select all that apply.
1: Controls the transport of materials from the outside fluids to within
2:Helps with the conduction of electrical currents in nerve and muscle cells
3: Aids in the regulation of cell growth and proliferation
Which are false of the mitochondria? Select all that apply.
1/4
,1: They are found far from the site of energy consumption.
2:They control free radicals.
High blood pressure is an example of which of the following?

hypertrophy is an increase in the size of an organ or tissue caused by an increase in the number of cells
True
Lack of nerve stimulation can cause cells to atrophy
True
A patient complains of chest pain and an elevated blood pressure. What are these examples of?
signs and symptoms
2/4
,Which of the following is true of a test's sensitivity?
If negative, it can safely be assumed that the person does not have a disease
Chemical agents (poison, alcohol) are examples of which of the following?
Etiologic factors
Define tertiary prevention and give an example:
Tertiary prevention occurs after a disease has been diagnosed and clinical intervention is needed to reduce
complications or deterioration. One example is the use of certain medications one must take after a heart attac
to help reduce the risk of a future event or death.
Compare and contrast the two types of gangrenous necrosis.
In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark
brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a form
of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is moist,
black, and under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by bacterial
action. The spread of tissue damage is rapid.
Explain what necrosis is and give an example and description of one type of necrosis.
necrosis is cell death to an organ or tissue with still being apart of a living person. An example of this would be
luiquefactive necrosis. this is when the cells die and the catalytic enzymes do not get destroyed after the cells
death. This could cause necrosis

List the 4 types of tissue found in the body. Pick 2 and give a description and example of each.
Epithelial tissue- covers the body's outer surface, it is avascular and gets its o2 from the capillaries found in the
neighboring connective tissues, and example of this is simple squamous tissue which means one layer of thin
cells.
Muscular tissue
Nervous tissue- is found all throughout the body, helps with communication between tissues and the central
nervous system. it aids in the functions of the body due to internal and external stimuli, helps with movement,
and electrical signaling. neurons are an example of this, they aid in communicating to other cells in the body,
they are held and supported by glial cells.
Connective tissue
What term means "cell eating" and engulfs and then kills microorganisms or other particulate matter?
Phagocytosis
What is the term to describe when cells use energy to move ions against an electrical or chemical gradient?
Active transport
