Muscle Kinesiology Anatomy & Physiology

Who came up with those LONG names? Many of the names come from Latin and the regional skeletal bones How many skeletal muscles can you name?

Muscle Movement Movement produced by contraction and pulling on attached bone Point of attachment of tendons to bones is called ORIGIN: attachment to INSERTION: attachment to

Group Action: muscles working in groups to produce body movement Prime Movers: (agonist) Muscles primarily involved in Antagonists: Muscles that Synergist: (helper) muscle that

Primary Antagonistic Actions of Muscular system (examples of) 1.Flexion/Extension: 2.Abduction/Adduction: 3.Elevation/Depression: various parts of

Cont. 4.Pronation/Supination: flexor and extenson muscles in 5.Dorsiflexion/Plantar flexion: tibialis anterior and soleus= 6.Inversion/Eversion: tibialis anterior and peroneus longus=

CHARACTERISTICEXAMPLESEXAMPLES IN HUMANS 1.Direction of fascicles relative to midline rectus = transverse = perpendicular oblique = 2.Location (i.e. the bone or body part that a muscle covers) frontal bone tibia 3.Relative Sizemaximus = longus = brevis = Seven ways we name muscles

4.Number of Origins (Heads) biceps = 2 origins triceps = 3 origins 5. Shapedeltoid = trapezius = serratus = orbicularis = Deltoid Trapezius Serratus anterior Orbicularis oris 6. Location of Origin and/or Insertion origin = insertion = Sternocleidomastoid 7.

Kinesiology Homework Using your Textbook, please label the muscles in your muscle packet L3:Create an outdoor (or indoor) exercise/action and describe which muscles are involved. For example: Kicking a soccer ball would involve 4 PM muscles—Which 4?? Create and Chart 3 separate activities
