Building Clay MusclesOrigins & Insertions
• Close eyes, blink, wink
• Closes mouth, grinds, jaw sideways
• Mastication, chewing – strongest muscles in our body
• Flex elbow, flex shoulder, turn a key
• Extends elbow, antagonist of biceps
• Side lifting humerus• Injection site
• Pull shoulder blades together,• Stabilize scapula,• Antagonist to trapezius
Pectoralis major: Flexes, adducts, & rotates humerus
Sternocleidomastoid
• Originates• Sternum• Clavicle
• Inserts• Mastoid process of
temporal bone
• Function• Rotate head• Flex neck• Extend neck
• Trapezius• Scapula toward spine• Rotate scapula• Scapula up or down• Head and neck
• To back or side• Assists breathing
• Arm extension, adduction, medial rotation
Quadriceps (see next slides for detail)-extends knee, flexes hip• Rectus femoris• Vastus medius• Vastus intermedius• Vastus lateralis
Hamstring – (see next slides for detail)flex knee, extend thigh, posture
• Semimenbranosus• Semitendinosus• Biceps femoris
• Plantar flexion• Flex knee• Propulsion• stabilization
Gluteus (see next slides for detail)
• Gluteus minimus• Gluteus medias• Gluteus maximus
• abduct thigh, rotate thigh, stabilization
• abduct thigh, rotate thigh, stabilization
• Extends thigh• Mobilization• Posture • injections
Abdominal muscles (see next slides for detail) – movement, support, protection, breathing• Transverse Abdominal• Exernal Obliques• Internal Obliques and• Rectus Abdominal
