The muscle system (names of all the muscles and categorized based on…

- - - - temporalis is the close jaw
      - Masseter closes the jaw
      - sternocleidomastoid flexes the neck or rotates the head.
  - - - Adductor Muscles adduct the thigh.
      - Gluteus Maximus is the booty.
      - Tibialis Anterior is the invert toe and dorsiflexes.
      - Extensor Digitorium Longus extends is toes.
      - Sartorius flexes the thigh on the hip
      - Quadracep group extends the knee, flexes the thigh.
      - Hamstring extends the hip when trunk is fixed
      - Gastrocnemius is the calf muscle .
      - Soleus is the calf, heel used for walking.
- - - - Synapse is the connection between nerve with muscle and other organs.
        
        Axon is the long portion of the nerve release a chemical called a neurontransmitter.
        
        Neurotransmitter is chemical messenger stored and released by synaptic vesicles into synaptic cleft.
        
        Synaptic cleft is a gap between neuron and sarcolemma.
        
        Acetylcholine is a neurotransmitter for skeletal muscle.
        
        Axonal termials ends of axon many branches, synaptic end bulbs are found in axonal terminal.
        
        Motor end plates are region across synaptic cleft rom the synaptic end bulbs
  - - - Action potentials are no longer generated so the Ca++ channels is SR close
