Anatomy/Physiology Flashcards
Three parts of a Neuron
1: Cell body
2: Axon
3: Dendrites
Three joint motions
1: Roll
2: Slide
3: Spin
5 Skeletal system functions
1: Shape
2: Protection
3: movement
4: blood production
5: store minerals
3 Layers of muscle
Epimysium
Perimysium
Endomysium (deepest)
Slow twitch fibers
1: Increased oxygen
2: Smaller
3: less force
4: Slow fatigue
Fast twitch fibers
1: Less oxygen
2: larger
3: more force
4: fast fatigue
Muscle spindle (Stretch)
1: change In length
2: Stretch reflex
3: Cause contraction
Golgi Tendon (tension)
1: attach to tendons
2: Change in muscle Tension
3: Cause relaxation
Blood flow in heart
1: Right A (no O) pumps into tricuspid
2: Right V (no-O) into Pulmonary valve
3: Left A (O) into Mitral Valve
4: left V (O to body) out Aortic Valve to rest of body
Blood vessels
1: Arteries (Away from heart)
2: Arterioles (Small branches of artery)
3: Capillaries (Small B Vessels O2 exchange Blood/Tissue
4: Venules (Small veins/connect capillaries to larger Veins)
5: Veins (Bring blood to heart from Cap/no O2
Blood functions:
1: Transport O2
2: Transport waste
3: Transport hormones
4: Carries heat
5: Regulates temp
6: clotting protects leaving
7: fights disease in sickness
Heart rate during Exercise
Count the number of beats in 6 seconds and add 0
or x 10
Measure Resting Heart Rate
5 min of complete rest
Cardiac Output
Blood pumped by heart per min
HR x Stroke Vol.
Stroke volume
The amount of blood pumped out of the heart with each contraction
