        Muscles
        
        Supraspinatus and Infraspinatus
    - - Deltoideus
      - Teres Major
      - +/- long head triceps
    - - Trapezius
        
        Pars Cervicals
        
        Insertion: Scapula Spine
        
        Origin for P-C -> Fibrous Raphe from C3 to T1-2
        
        Pars Thoracic
        
        Origin: for P.T -> Supraspinous Ligaments of T3-9
        
        Nerve = Acessory Nerve
        
        Function: When both the PC and PT contact together - they elevate the scapula
        
        Individually they protract the limb forward (swing foward)
      - Latissimus Dorsi
        
        Origin: Spinous Process and Thoracolumbar Fascia of Thoracic Verb: 4-13 and L1-7
        
        Insertion: Teres Tuberosity of Humerus
        
        Also inserts on the the aponeurosis medially to the triceps brachii/ trees major/ deep pectoral muscles
        
        Action: Pulls Trunk Foward (When the foot is fixed foward)
        Action: Retracts the limb and flexes the shoulder when the forelimb is free
      - Deep Pectoral
        
        Action: Powerfully retracts the most advanced limb
        Action: Extends the shoulder joint
        Action: Suspends the thorax
        
        Origion: Sternabrae 1-8
        
        Insertion: Inserts on the lesser tubercle (middle of tricipital line) -> Humerus
      - Superficial Pectoral
        
        Action: The superficial pectoral -> adducts the limb.
        Action: The superfical pectoral assists in the suspension of the trunk
        Action: Depending on the location -> the Superficial Pectoral protracts and retracts (move foward and back) the limb
        
        Origion: Cranial End of the Sternum
        
        Proximal 2/3rds of the cranial edge of the humerus shaft
      - Rhomboid
        
        Pars Cervicis
        
        Action: The Rhomboid Muscle draws the scapula against the trunk
        Action: Rotates scapula to retract the limb
        Action: Elevates the scapula
        
        Origion of the Pars Cervicis: Median raphe of the neck C2/3 -> T3
        
        Insertion: Caudal Aspect of the Dorsal border of the scapula
        
        Pars Thoracis
        
        Origin: Spinous Processes of T4-6/7
        
        Pars Capitis
        
        Origion: Thin tendon from Occiput
      - Ventral Serrate
        
        Action: The Ventral Serrate suspends the thorax beteen pectoral limbs (sling like support)
        Action: Little help in forced respirtation
        Action: Manipulates the scapula to advance and retract the limb (medial side)
        
        Origion: Transverse process of C3-7 and 1st -> 8th rib
        
        Inserts: Facises Serrate of the Medial Scapula
      - Brachiocephalicus
        
        Cleidocervicalis
        
        Origin: Clavicular Tendon
        
        Inserts: Aponeurosis over the cranial half of the neck
        
        Cleidomastoideus
        
        Inserts: Mastoid Processes of the Temporal Bone
        
        Cleidobrachialis
        
        Action: Advances the free limb (protracts) -> +/- extends the glenohumeral joint (shoulder joint) -> fixes and depresses the neck + draws the head and neck laterally
        
        Inserts: on the cranial edge of the distal part of the humerus * tendon of insertion of the cleidobrachialis passes between the biceps brachia and the brachialis muscle
      - Omotransverse
        
        Action: The omotransverse protracts the limbs (advances)
        
        Nerve: It's innervated by the accessory nerve
        
        Origin: Wing of the Atlas (C1)
        
        Inserts: Inserts on the dorsal aspect of the scapula spine
  - - - Biceps Brachii
      - Brachialis
    - - Tricep Brachii
        
        Lat
