- - - - Neuromuscular Junction
        
        Components of Sacromere
        
        Actin(thin)- Contains tropopin and tropomyosin
        
        Tropopin- binds with CA+2
        
        Tropomyosin- prevent from forming cross bridge
        
        Atp release phosphate and ADPane when cocking back
        
        Cross bridge forms, ATP and Tropomyosin attach
        
        Myosin(thick), myosin binding sites have atp
        
        Sacromatic reticulum- Houses CA+2
        
        T Tubules- Nerve impulse travels through this
        
        Cisternae- between T tubules
        
        Neurotransmitters- ATP, Norepinephrine, epinephrine
        
        Neuron-
        
        Synaptic cleft- Gap between membranes of neuron & muscle fiber
        
        Synaptic vesicles- houses neurotransmitters
        
        Mitochondria-
        
        Synapse- Axon of motor neuron
        
        Motor neuron- Axon
        
        Motor end plate- sarcolemma tightly folded
- - - - Atrophy- Decrease in muscle mass
      - Hypertrophy- Increase in muscle mass
- - - - Movement of viscera, vasoconstriction
      - Striations- Absent
      - Location: Walls of blood vessels
      - Single nucleus
      - Involuntary
      - Self excisitng rhymatic- single unit
- - - - Neck
        
        Sternohyoid
        
        Sternocleidomastoid
  - - - Arm
        
        Palmaris Longis- pinky side
        
        Flexor carpi ulnaris- right,
        
        Triceps brachii- beneat bicep brachii
        
        Brachioradialis- Forearm
        
        Deltoid- Shoulder
        
        Brachialis- Muscle next to biceps brachii
        
        Flexor carpi radialis- right
        
        Prontar teres
        
        Biceps Brachii- Upper arm
    - - Hamstrings
        
        Calf Muscles
        
        Tibialis Anterior
        
        Gastronemius
        
        Extendor Digitorium Longus
        
        Fibularis Longis
        
        Satorius
        
        Tensor fascia lata
        
        Vastus lateris
        
        Vastus medialis
        
        Gracillis
        
        Soleus
        
        Adductor longus
        
        Iilliposoas
        
        Petineus
        
        Illiobial tract
- - - - Stimulated by membrane impulse
      - Uses ATP from cellular respiration
      - Involve reaction between myosin and actin
      - Uses ATP and Calcium Ions
