45
How is a sprain caused?
By a tear or excessive stretching of a ligament
46
How is a strain caused?
By a tear or excessive stretching of a tendon or muscle
47
What is bursitis?
When the bursa between joints becomes inflamed
48
What is tennis elbow?
When the tendons connecting the forearm to the outside of the elbow are inflamed
49
What are the major bones of the body?

``` Cervical Thoracic Lumbar Sacrum Coccyx ```
51
What is a pivot joint?
A joint that provides rotation of one bone around another (i.e. C1 & C2)
52
What is a hinge joint?
A joint that provides flexion and extension (i.e. elbow)
53
What is a saddle joint?
A joint that provides flexion, extension, adduction, abduction, and circumduction (i.e. between the carpal and metacarpal of the thumb)
54
What is a gliding joint?
A joint that provides gliding movements between two bones (i.e. tarsal bones)
55
What is a condyloid joint?
A joint that can provide flexion, extension, abduction, adduction, and circumduction (in between metacarpals and phalanges)
56
What is a ball and socket joint?
A joint that provides flexion, extension, abduction, adduction, internal and external rotation (i.e. hip)

What are the two types of tissue that exist within human bone?
Compact bone | Spongy bone
66
Where is compact bone located and what is its purpose?
The surface of bones | To protect the bone by allowing it to bear the weight of the body
67
Explain what a spongy bone is.
It contains more spaces than compact bone | Red bone marrow is housed within it
68
What are the major structures of the cardiovascular system?
``` Blood vessels Heart Superior and inferior vena cava Aorta Left and right atrium Left and right ventricle Mitral valve Tricuspid valve Aortic valve Pulmonary valve ```
69
What do blood vessels consist of?
Arteries Arterioles Veins Venules
70
What is the cardiovascular system responsible for?
Pumping 5L of blood through the body at any given time
71
How long does it take for a red blood cell to make its way through the human body?
1 minute
72
What is the function of the superior vena cava?
It collects blood from the upper half of the body
73
What is the function of the inferior vena cava?
It collects body from the lower half of the body
74
What do the superior and inferior vena cava do with the blood they collect?
Take it to the right atrium
75
Is the blood collected by the superior and inferior vena cava oxygen-deficient or oxygen-rich?
Oxygen-deficient
76
What path does the oxygen-deficient bloodafter leaving the right atrium?
``` Tricuspid valve Right ventricle Pulmonary valve Pulmonary artery Lungs Left atrium Mitral valve Left ventrical Aortic valve Aorta Rest of the body ```
77
What happens to the oxygen-deficient blood when it enters the lungs?
It becomes more oxygen rich
78
How does the oxygen-rich blood return to the left atrium?
Via the pulmonary vein
79
What is the function of the cardiovascular system?
Remove metabolic waste Provides nutrients to the body Provides protection from foreign microbes and viruses through white blood cells Keeps our bodies in a state of homeostasis
80
What does exercise condition the sympathetic and parasympathetic nervous systems to do?
It conditions the sympathetic system to become less active during rest and the parasympathetic system to become more active during rest
81
What does the respiratory system consist of?
``` Larynx Trachea Lungs Pleural cavity Pleural membrane Bronchi Bronchioles Alveoli ```
82
What is the process of respiration?
1) Breath: brings oxygen into the lungs 2) External respiration: Oxygen from the blood and carbon dioxide are exchanged within alveoli 3) Internal respiration: Excess carbon dioxide is carried away from the lungs by blood 4) Cellular respiration: Oxygen is used to break down sugar within cells to produce water, ATP, energy, and carbon dioxide
83
When is the sympathetic nervous system activated and what is its purpose?
Early in the exercise session | Increase heart rate and blood pressure as response to stress of exercise
84
When is the parasympathetic nervous system activated and what is its purpose?
Later in the exercise session Help blood pressure and heart rate plateau during the session & decrease heart rate and blood pressure to near resting levels during cooldown
85
What does exercise condition the sympathetic and parasympathetic nervous systems to do? Why?
It conditions the sympathetic system to become less active during rest and the parasympathetic system to become more active during rest It allows the blood pressure and heart rate to remain low and keep them near normal levels during stressful situations
86
What does conditioning of the sympathetic and parasympathetic nervous systems allow the blood pressure and heart rate to do?
To remain low and keep them near normal levels during stressful situations
