Swole
Thin covering of connective tissue around a muscle
What is fascia
Cytoplasm of Muscle Fibers
What is Sarcoplasm
Functional unit of muscle, contracts
What is a sarcomere
Sarcoplasmic Reticulum holds this
What is Calcium
Muscle wasting away
What is atrophy
Muscle that is striated, voluntary, and multi-nucleated
What is Skeletal Muscle
These bind to actin filaments
What are myosin heads
Connective Tissue in and Closely surrounding a muscle
What are Epimysium, Perimysium, and Endomysium
I band
What is thin filaments, Light band, composed of this actin filaments
Plasma Membrane of muscle fibers
What is sarcolemma
Connective Tissue COVERINGS over skeletal muscles
What are Fascia, Tendon, Aponeurosis
FTA= future teachers of America
A band
Thick and thin filaments, Dark band
Sarcolemma invagination that helps internalize the muscle impulse
What is a T tubule
Surrounds the fascicles within a muscle
What is Perimysium
Myofibrils made up of these
What are thin actin filaments and thick myosin filaments
Fascicles are
What are bundles of muscle fibers
Surrounds muscle fibers
What is endomysium
H zone
Center of A band, thick filaments only
Enzyme that breaks down the neurotransmitter of skeletal muscle contraction:
what is Acetylcholinesterase
Z line
Anchors thin filaments, boundary of sarcomere (runs from Z disc to Z disc) , Center of I band
The regulatory protein that senses calcium
What is troponin
Muscle fiber unit that extends from one z-line to the next z-line
What is a sarcomere
The regulatory protein that blocks myosin from binding to actin
What is tropomyosin
M Line
Anchors the thick filament center of A band and center of sarcomere
this is the neurotransmitter
what is acetylcholine (ACh)
