100
The two kinds of protein filaments that produce the striations in muscles.
What are actin and myosin
100
The idea that actin and myosin move over each other to shorten a muscle
What is the sliding filament theory
100
This attaches muscle to bone
What is a tendon
100
The motor neuron and the muscle fibers that it controls
What is motor unit
100
When a muscle loses its ability to contract after prolonged use
What is muscle fatigue
200
Another name for a muscle bundle
What is fascicles
200
These have cross bridges that allow the filaments to move.
What is myosin
200
Layers of fiberous connective tissue
What is fascia
200
Specialized portion of muscle fiber membrane at a neuromuscular junction
What is motor end plate
200
Increasing the number of motor units being activated
What is recruitment
300
The segment of a myofibril that extends from Z line to Z line
What is a sarcomere
300
This is the 1st source of energy for muscle contractions
What is ATP
300
Connective tissue that forms a broad fibrous sheet
What is aponeuroses
300
Neurotransmitter that must be present to stimulate a muscle fiber.
What is acetylcholine
300
Sustained contraction
What is tetanic contraction
400
These make up a muscle fiber
What are myofibrils
400
The delay between when a muscle is stimulated and the time it responds
What is latent period
400
Cell membrane
What is sarcolemma
400
Decomposes acetylcholine
What is acetylcholinesterase
400
Energy from these molecule is used to rebuild ATP for ADP
What is creatine phosphate
500
This section of a muscle fiber is made up only of actin
What is the I band
500
Membranous channel that extends inward from a muscle fiber membrane and passes through the fiber
What is transverse tubule
500
Tissue that extends inward and separates the muscle bundles into small cmopartments.
What is perimysium
500
This toxin can prevent the release of acetylcholine from motor neuron axons and cause illness
What is botulinum (botulism)
500
Where glucose is synthesised from lactic acid
What is the liver
