Cards

Term
Radial pulse
Definition
Most common source of the pulse found in the wrist
Term
Brachial artery
Definition
Most significant blood vessel in the upper arm for finding blood pressure
Term

Adenosine triphosphate

(ATP)

Definition
Chemical required for proper muscle function and responsible for metabolism, muscle contraction, and the ability of the cell to synthesize proteins
Term
ATP
Definition
Used to repair tissue and turned into glycogen or stored as fat
Term
ADP
Definition
ATP stored until it combines with phosphocreatine during intense muscle contraction
Term
Anaerobic glycolysis
Definition
Sugar can broken down into lactic acid, ethanol. and ATP
Term
Downside of anaerobic glycolysis
Definition
Generates pyruvic acid causing cramping and fatigue
Term
Aerobic production of ATP
Definition
Sugars are converted into ATP using oxygen
Term
Aerobic glycolysis
Definition
Helps evacuate toxins and acids from the muscles preventing fatigue and cramping
Term
Kilocalorie
Definition
Amount of energy required to raise the temperature of 1 kg of water by 1 degree C
Term
Caloric expenditure
Definition
Amount of calories burned by the human body
Term
Caloric intake
Definition
Sum total of calories consumed by the body
Term
Caloric deficit
Definition
Number of calories that must be burned in order for a person to lose weight
Term
Energy balance
Definition
Consuming same amount of calories as one burns
Term
Simple carbohydrates
Definition
Comes from nature such as fruit and honey
Term
Complex carbs
Definition
Contain more vitamins,minerals, and nutrients
Term
Proteins
Definition
Essential for creation of DNA and formation and maintenance of body tissue
Term
Bones
Definition
Composed of approx. 1/4 protein
Term
Saturated fats
Definition
Solid at room temperature and associated with heart disease
Term
Monounsaturated fats
Definition
Healthy fats
Term
Polyunsaturated fats
Definition
Useful in blood clotting and found in fish and plant oils
Term
Triglycerides
Definition
Found in vegetable and animal fats and oils
Term
Motor unit
Definition
Motor neuron and its corresponding muscle cells
Term
Golgi tendon organ
Definition
Made up of collagen that connect the body of a tendon to muscle fibers
Term
Golgi tendon organ (GTO)
Definition
Muscle contracts, this stretches?
Term
Muscle spindles
Definition
Stimulated whenever muscles are lengthened or shortened
Term
Proprioceptive sense
Definition
Body's unconscious perception of its own movement and its position within the physical world
Term
Kinesthetic sense
Definition
Body's ability to note and take account of the movements and its various parts
Term
Slow twitch fibers
Definition
More efficient in their use of oxygen and get energy from aerobic glycolysis; long-term, low intensity exercise
Term
Fast twitch fibers
Definition
Generate energy quickly through anaerobic glycolysis; quick violent movements
Term
Static
Definition
holding muscle in extended position for 30 secs-1 min
Term
Dynamic
Definition
Muscle is brought into its stretched position through series of short, violent motions; increased risk of injury
Term
Cardiac output
Definition
Total volume of blood pumped from heart
Term
SV X HR=
Definition
Cardiac Output (Q)
Term
Stroke volume
Definition
amount of blood pumped by an individual contraction of the heart
Term
Respiration
Definition
exchange of oxygen for carbon dioxide within the cells of the body
Term
Aerobic capacity
Definition
abililty of blood to carry oxygen throughout the body
Term
Systolic BP
Definition
amount of force produced when heart contracts
Term
Diastolic BP
Definition
pressure of blood in arteries when heart is relaxing
Term
Steady state
Definition
meeting all of body's oxygen needs during exercise
Term
Muscular hypertrophy
Definition
increase in size and number of muscle cells
Term
Muscular atrophy
Definition
decrease in size and number of muscle cells
Term
CHD
Definition
gradual diminshment of blood to heart, caused by narrowing or blocking of coronary artery
Term
Law of inertia
Definition
body at rest or in motion will tend to stay at rest or in motion unless acted upon by some other force
Term
Law of acceleration
Definition
force acting on the body is equal to the mass of the body multiplied by acceleration
Term
Law of action and reaction
Definition
two bodies come into contact with one another their impact on one another is equal in magnitude and opposite in direction
Term
Mass
Definition
quantity of matter in an object
Term
Force
Definition
push or pull that is exerted on an object; has both magnitude and direction
Term
Force
Definition
mass X acceleration
Term
Friction
Definition
force created by an object's contact with the ground as it moves
Term
Center of mass
Definition
perpendicular to ground along same line as geometric center of the base if the individual wants to have maximum stability
Term
Sagittal plane
Definition
divides between right and left sections
Term
Frontal plane
Definition
divides between front and back sections
Term
Transverse plane
Definition
divides into upper and lower sections
Term
agonist
Definition
muscle that initiates movement
Term
antagonist
Definition
opposite of agonist; restores joint to its normal arrangement
Term
synergist
Definition
performs or assists in performing motion performed by agonist; restrains agonist when muscle is too strong
Term
diaphsysis
Definition
central shaft of bone
Term
ephiphyses
Definition
two knobby ends of a bone
Term
alveolar structure
Definition
fibers are arranged to best handle stress on the bone
Term
diaphysis
Definition
contains bone marrow and blood cells are produced here
Term
periosteum
Definition
outside of bone that carries blood vessels and assists in repairing fractured bones
Term
ball and socket joint
Definition
connecting surface is rounded and other concave
Term
hinge joint
Definition
convex surface of one joint fits against the concave surface of the other; occurs in one plane
Term
gliding joint
Definition
connecting surfaces are flat so movement is limited
Term
ellipsoid joint
Definition

oval-shaped section of one bone fits into an elliptical cavity in another; allows for movement in 2 planes;

 ex: wrist

Term
pivot joint
Definition
pointed or rounded area in one bone fits into a ring-like structure on another; rotation is only movement
Term
saddle joint
Definition
both connecting surfaces are shaped like saddles, and fit together snugly; occur in 2 planes; ex: thumb
Term
joint capsule
Definition
sleeve that surrounds a joint, preventing any loss of fluid and binding together teh ends of the bones in the joint
Term
sarcomere
Definition
smaller units in a muscle cell
Term
Muscle contraction
Definition
nerve stimulates the muscle and the thin filaments compress within the sarcomere
Term
sliding filament theory
Definition
myosin pulls actin closer together resulting in decrease in the length of the muscle (contraction)
Term
summation
Definition
number of stimuli produce a response that a single stiumulus could not produce by itself
Term
tetanus
Definition
permanent contraction of a muscle; ex: lockjaw
