The neuromuscular system Flashcards
neuromuscular system
the nerves and the muscles working together in order to produce different movements
Type 1 slow oxidative
a slow twitch muscle fibre used during endurance events
Type 11a fast oxidative glycolytic
a fast twitch muscle fibre with some resistance to fatigue
Type 11x fast glycolytic
a fast twitch muscle fibre capable of producing a powerful contraction
motor unit
made up of a motor neurone and skeletal muscle fibres
motor neurone
nerve cells located in the mtor unit, recieve impulses sent from the brain
wave summation
repated nerve impulses resulting in a stronger contraction
tetanic contraction
a number of motor units recieving impulses at the same time, resulting in a more powerful contraction
spatial summation
a number of motor units reciving impulses at the same time, resulting in a more powerful contraction
PNF
Proprioceptove Neuromuscular facilitation, an advanced stretching technique
Proprioceptors
receptors found in the muscles tendons and joints, relay message to the brain regarding muscle movement
muscle spindles
a proprioceptor the detects tension and signals for a muscle to relax
isometric contraction
when a muscle contracts without any movement at a joint
