Q

Agonist vs. Antagonist

A

Q

Origin vs. Insertion

A

Origin = attaches to the bones which are more “stationary” (axial skeleton)

Insertion = Attaches to the bone that is moved most

Q

Parts of the Muscle

Study These Flashcards
A

Made up of groups of muscle fibers called fascicles surrounded by a connective tissue layer called perimysium

22
Q

All or None Principle

Study These Flashcards
A

The muscle or nerve responds completely or not at all.

23
Q

Sliding Filament Theory

Study These Flashcards
A

The thin actin filaments slide between the thick myosin filaments – the filaments do not contract themselves so they stay the same length. This causes the sarcomeres to shorten in length, in turn shortening the muscle fibres and causing contraction.

24
Q

The Reflex Arc

Study These Flashcards
A
  • Involuntary, instant response to a stimulus.
  • stimulus receptor
  • Sensory neuron (afferent)
  • Interneuron (efferent)
  • Motor neuron
  • Effector organ (effector)
25
Aerobic vs. Anaerobic Systems
AEROBIC - fueled by oxygen ANAEROBIC - fueled by energy stored in muscles
26
The 3 Metabolic Pathways
ATP-PC Glycolysis Cellular Respiration
27
ATP-PC
10-15 seconds (sprinting, jumping, weightlifting)
28
Glycolysis
15 seconds - 3 minutes (200-800 meter runs or a shift in hockey)
29
Cellular Respiration
120 seconds and beyond (marathons)
30
Pyruvate and Lactic Acid
Pyruvic acid = supplies energy to living cells through the Kerbs cycle Lactic acid = A chemical your body produces when your cells break down carbohydrates for energy.
31
Slow Twitch vs. Fast Twitch Muscle Fibres
SLOW TWITCH - red - generate tension slowly - longer FAST TWITCH - pale - Tense and relax quickly - Low endurance
32
4 Layers of the Heart Muscle
The sac surrounding the heart (pericardium) Allows the heart to expand and contract. - Outer layer (epicardium) - Muscle tissue (myocardium) - The final layer of tissue inside the heart (endocardium)
33
The function of the Atria and Ventricles
Ventricles = pump blood out of the heart and into either systemic or pulmonary circulation. Atria = receives blood returning to the heart from other areas of the body.
34
Parts of the Vascular System
The heart, blood and blood vessels
35
Cardiac Output
the product of heart rate (HR) and stroke volume (SV)
36
Heart Rate
The number of times your heart beats per minute. Normal resting heart rate = 60 to 100 beats per minute.
37
Stroke Volume
The volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction.
38
Blood pressure
The pressure of blood pushing against the walls of your arteries.
39
Systolic vs. Diastolic
SYSTOLIC VS. DIASTOLIC PRESSURE (Both are types of blood pressure) Systolic Pressure =measures the pressure in your arteries when your heart beats. Diastolic Pressure = measures the pressure in your arteries when your heart rests between beats.
40
Conductive Zone vs. Respiratory Zone
Conducting zones = (nose to bronchioles) form a path for the conduction of the inhaled gases Respiratory zone = (alveolar duct to alveoli) where the gas exchange occurs.
41
Role of the epiglottis?
Allows air to pass into the larynx and lungs
42
How are O2 and CO2 moved around the body?
O2 = dissolved in the blood and chemically combined to hemoglobin. CO2 = is carried physically dissolved in the blood and chemically combined with blood proteins.
43
What is an Oxygen Deficit?
It occurs when the body needs more oxygen than is immediately available to produce energy.
44
Define RICE
Rest, Ice, Compression, Elevation
45
What's the difference between 1st, 2nd, and 3rd degree sprains
1st - damage to fibres/stretching 2nd - partial tearing of ligament 3rd - complete tear of ligament
46
3 types of muscle contraction
1. Concentric 2. Isometric 3. Eccentric
47
Cellular respiration involves what energy pathways?
- Glycolysis - Kreb's cycle - Electron Transport Chain
48
Afferent vs Efferent
Afferent = Carries info from sensory receptors to the central nervous system. Efferent = Carries motor info away from the central nervous system.
49
Dislocation versus separation
BOTH ARE SHOULDER INJURIES Dislocation - when arm bone loses contact with shoulder blade Separation - occurs between the shoulder blade to the collar bone
50
Labrum vs meniscus
Lambrum - shoulder/hip Meniscus - knee
51
Acl vs mcl
Acl - anterior cruciate ligament located on legs frontal part of body Mcl - medial collateral ligament located on the inside of the leg pointing inwards towards the body (bigger than ACL)
