muscles Flashcards
flexion of hip joint is carried out by…
rectus femoris
tricep muscles is an
extensor
contraction happens because of
relaxation and contraction
agonist
aka. ‘Prime mover’ muscle that contracts
antagonist
muscle resists against the agonist, or relaxes
protagonist
aka. synergist, helps assist the agonist
isometric contraction
change the tone without changing the length
isotonic contraction
changing the length without changing the tone
muscle spindle=
contraction
golgi tendon=
relaxation
muscle tone is…
how contracted a muscle is at rest(aka. passive tone)
function of muscle tone…
maintain posture and ready muscles for sudden action
individual fibres and whole muscle
individual fibres can be completely contracted, but a whole muscle can be partially contracted with only some of fibres firing
muscles in back
trapezius, teres major, erector spinae, latissmus dorsi,
muscles in hamstring(posterior upper leg)
bicep femoris, semimembranosis, semitendinosis
