sliding filament theory Flashcards
1
Q
sarcolemma
A
plasma membrane that surrounds a muscle fiber
2
Q
sarcoplasm
A
cytoplasm of a muscle cell
3
Q
sarcomere
A
units of skeletal muscle containing myosin and actin
4
Q
sarcoplasmic reticulum
A
transport electrochemical substances involved in muscle activation
5
Q
motor unit
A
a motor neuron, its pathway, and the muscle fibre it stimulates
6
Q
all-or-none principle
A
the principle that the neuron either fires at 100% or not at all
7
Q
sliding filament theory
A
the muscle as a whole contracts, not shortens through an overlapping of actin and myosin filaments
8
Q
what does the sliding filament process result in?
A
shorting of the sarcomere (muscle contraction)
