One motor neuron and all the muscle fibers it innervates
Motor neuron
Outside of a muscle
Epimysium
All muscle fibers contract with equal force fully or not at all is what rule?
All or none
I needed too much energy fast. Now I have ...
oxygen debt
Biggest muscle of the body
Gluteus maximus
A chemical released by a neuron
Neurotransmitter
Thick protein filament in sarcomere
Myosin
All muscle motor units have been fully contracted
Maximal stimulus
Many steps including Krebs cycle
Aerobic respiration
2 muscles in upper arm
Biceps and triceps
The repeating unit of a myofibril
Sarcomere
Thin protein filament
Actin
This transmits the action potential down to to the sarcoplasmic reticulum
T tubule
This builds up with anaerobic respiration
Lactic Acid
Jaw muscle
Masseter
Interface between a neuron and another cell
Synapse
Zig zag line that connects to Actin
Z disk
This will roll onto the active sites of myosin to block ATP
Tropomyosin
What can generate energy for 10 seconds in a muscle only?
Creatinine phosphate
This tendon helps you push off with your foot. It comes from the calf muscle
Achilles
Stimuli of increasing strength that create more action potentials in more motor neurons
Submaximal stimulus
zone were only myosin is present when sarcomere is not contracted
H Zone
This neurotransmitter signals a muscle cell
Acetylcholine
To stop contraction I might need this enzyme
Acetylcholinesterase
Smallest muscle in the body
Stapedius
