What are the muscles in the abdominal wall? (4)
External oblique, internal oblique, transverse abdominus, rectus abdominus
What are the muscles involved in thigh movement? (9) (4 are groin muscles)
Psoas major, gluteus maximus, gluteus medius gluteus minimus, tenso fascia lata, [adductor longus, adductor magnus, gracillis, pectineus]<– groin muscles

What are the muscles involved in foot movement? (5)
Tibialis anterior, extensor digitorum longus, fibularis longus, gastrocnemius, soleus
Agonist
the “prime mover”, the muscle that is contracting
Antagonist
Muscle that is relaxing and causes movement opposite to agonist
Elbow Extension
Prime mover: triceps brachii
Antagonist: biceps brachii
Elbow flexing
Prime mover: biceps brachii
Antagonist: triceps brachii
Flexion Vs Extension
Flexion- brings parts together
Extension- straightens parts out
Abduction v adduction
Abduction- taking away from midline
Adduction- bringing parts toward midline
Pronation vs Supination
Pronation- turning palm so it faces down
Supination- turning palm so it faces up
Elevation vs Depression
Elevation- raising up
Depression- lowering
Circumduction vs Rotation
Circumduction- moving part so it follows circular path
Rotation- moving part around axis
Inversion vs Eversion
Inversion- soles inward, facing each other
Eversion- soles outward going away from each other
Origin vs the insertion
Origin- attatchment of a muscle tendon to the stationary bone
Insertion- attatchment of a muscle tendon to the moveable bone
Sternocleidomastoid (Origin and insertion)
Origin: sternum and clavicle
Insertion: mastoid process
Trapezius (origin and insertion)
Origin: occipital bone and cervical vertebrae
Insertion: clavicle and scapula
Pectoralis minor (origin and insertion)
Origin: upper ribs
Insertion: coracoid process
Deltoid (origin and insertion)
Origin: actomion proces and spine of scapula, clavicle
Insertion: humerus
Pectoralis major (origin and insertion)
Origin: clavicle, sternum and costal carilage of ribs
Insertion: humerus
Biceps Brachii (origin and insertion)
Origin: glenoid cavity and caracoid process
Insertion: radius
Triceps Brachii (Origin and insertions)
Origin: 1 scapula, 2 humerus
Insertion: ulna
Set up of the abdominal wall (superficial to deep) and why is contraction different
- External Oblique
- Rectus Abdominus
- Internal Oblique
- Transverse Abdominus
*Contraction decreases volume of abdominal cavity and increases pressure
Biceps Femoris (Origin and insertion)
Origin: femur and pelvis
Insertion: fibula and tibia
Sartorius (Origin and insertion)
Origin: lateral anterior ilium
Insertion: medial tibia
Quadriceps femoris (Origin and insertion)
Origin: Ilium and femur
Insertion: Patella
Gastrocnemius (Origin and insertion)
Origin: femur
Insertion: Achilles tendon
