62
Modality
How you are receiving information. In imaging it could be x-ray, CT, or MRI. Senses are also modalities.

Tibia
68
What is the name of the lateral bone of the 2 in the lower leg?
Fibula
69
Define Axial
Bones of the central axis of the body; skull, vertebral column, sternum, ribs
70
Define Appendicular Skeleton
Bones of the appendages; such as clavicle, scapula, pelvis, and bones creating the arms and legs.
71
Define Homeostasis
The condition of equilibrium (balance) in the body's internal environment due to the constant interaction of the body's many regulatory processes.
72
Which are more common;
| negative or positive feed back loops?
Negative feed back loops
73
Name some positive feed back loops
1. Child birth
2. Loss of blood
3. and other examples I am sure
74
What are the consequences of a positive feed back loop?
"A positive feed back system tends to strengthen or reinforce a change in one of the body's controlled conditions.
75
What are the consequences of a negative feed back loop?
"A negative feedback system reverses a change in a controlled condition."
76
Name some negative feed back loops
An example is if your blood pressure raised due to anxiety, a negative feed back loop would bring it back to homeostasis. Negative feed back loops usually return things to a normal range. (blood glucose, heart rate, ect.)
77
How do negative and positive feed back loops stop?
Negative: When a set pre-existing point is returned to. (temperature, glucose, ect)
Positive: Only stopped by an outside mechanism. (baby is delivered, elements needed to clot blood are depleted, ect)
78
Define Signs
Something that can be observed or measured. Examples are fever, swelling, redness, vomiting ect.
79
Define Symptom
"A subjective change in body function not apparent to an observer." Examples include: nausea, shortness of breath, headache ect.
80
Define Syndrome
"is a group of signs and/or symptoms that commonly occur together."
81
Define Regulatory Processes
I am guessing this is completed through negative feed back systems and is a way of returning systems to homeostasis. It is not defined in the book or study guide.
82
Define Disease
"Any change from a state of health", or a disruption from normal physiology.
83
Give a simple explanation of cause of autoimmune diseases.
In the first few months of life the body decides what is self and what is non-self. Unknown environmental triggers cause T and B cells to create immune response against self-antigens.
(Text book, pg 867)

87
Explain Vector Transmission
If the disease is transmitted by a third party such as a tick and Lyme disease, mosquito and malaria, ect. A vector can be a human.
88
What is a carrier?
"If a vector is a person who does not appear to be ill, they are called a carrier."
89
What is a common vehicle transmission?
"Infection or disease carried through food, water or bodily fluids."
90

infections "from the external environment"
99
Explain significant figures
"Sig fig's assure that we don't create numbers where none existed before. Whichever number in a calculation has the fewest digits is the number of significant figures."
