The Muscular System Flashcards
(31 cards)
Aerobic Respiration / Metabolism
The process which cells use O2 to make energy
Insertion
another word for attachment site
Isotonic Contraction
when the tension stays the same but the length changes, this is known as what?
Facial Tissue
muscles are encased in what?
Agonist
another word for ‘prime mover’
Type 1
slow twitch fibers
Action Potential
muscle contractions begin with this:
Synergist
these assist Agonists
Isometric Contraction
when the length stays the same, but the amount of tension changes, this is known as what?
Tendon
muscles are anchored down to the bone by
Myosin
the thick filament part of a sacromere
Concentric Contraction
flexing the bicep to shorten the muscle is know as what type of contraction?
Calcium and Sodium
our muscles need these two elements to produce movement
Proprioceptors
these are responsible for detecting our bodies position in space
Muscle Spindles
Stretch receptors are also know as what
Phasic
muscle type that has high power but low endurance
Golgi Tendon Organ
these detect the amount of tension in a muscle
2A
fast twitch fibers only found in animals
2B
fast twitch fibers only found in humans
Eccentric Contraction
flexing the tricep to lengthen the bicep is known as what type of contraction
Actin
the this filament part of a sarcomere
Antagonist
these perform the opposite action
Trigger points
tender points are often associated with this
Sarcomere
what is the functional unit of muscle tissue
