neuron function
a neural function IS WHEN MOTOR NUERONS ATTACH THEMSELVES TO MUSCLE FIBERS, WHICH CREATES A MOTOR UNIT. in order for a skeletal muscle to contract it must get a signal from the nervous system called the motor neuron. MOTOR NUERONS CONTROL THE INTENSITY OF THE CONTRACTIONS OF THE MUSCLES.
TYPES OF FIBERS
FAST-TWITCH FIBERS- FAST TWITCH FIBERS ENABLE A GREATER CAPACITY FOR POWERFUL BURST SUCH AS SPRINTING.
SLOW-TWITCH FIBERS- SLOW TWICTH FIBERS ENABLES FOR LONG ENDURANCE AND ANAROBIC ACTIVITY. |
