Muscle Vocab Flashcards
Principal contractile proteins, make thin filaments
Actin
muscle opposing/reversing movement
Antagonists
“shoot-like” indirectly attaches muscle to bone, cartilage, or another connective tissue covering
Aponeurosis
made of sheets of connective tissues found below skin
Fascia
the movable attachment of a muscle as opposed to its origin
Insertion
cells in brain + spinal cord that help us move
Motor Newron
A wave of excitation transmitted through tissue
Muscle Impulse
contractile organelles found in the cytoplasm of muscle cells
Myofibrils
principle contractile proteins found in muscle make up thick fibers
Myosin
attached to the “immovable” bone, anchor/leverage
Origin
synaptic vesicles filled w/ a chemical
Neurotransmitter
temporary oxygen shortage in body
Oxygen Debt
muscle responsible for causing much movement
Prime Mover
process by which different motor units activated to control muscle contraction
Recruitment
Basic contractile unit of myocyte “muscle fiber”
Sarcomele
