Q

Elbow flexing

A

Prime mover: biceps brachii
Antagonist: triceps brachii

17
Q

Flexion Vs Extension

A

Flexion- brings parts together
Extension- straightens parts out

18
Q

Abduction v adduction

A

Abduction- taking away from midline
Adduction- bringing parts toward midline

19
Q

Pronation vs Supination

A

Pronation- turning palm so it faces down
Supination- turning palm so it faces up

20
Q

Elevation vs Depression

A

Elevation- raising up
Depression- lowering

21
Q

Circumduction vs Rotation

A

Circumduction- moving part so it follows circular path
Rotation- moving part around axis

22
Q

Inversion vs Eversion

A

Inversion- soles inward, facing each other
Eversion- soles outward going away from each other

23
Q

Origin vs the insertion

A

Origin- attatchment of a muscle tendon to the stationary bone
Insertion- attatchment of a muscle tendon to the moveable bone

24
Q

Sternocleidomastoid (Origin and insertion)

A

Origin: sternum and clavicle
Insertion: mastoid process

25
Q

Trapezius (origin and insertion)

A

Origin: occipital bone and cervical vertebrae
Insertion: clavicle and scapula

26
Q

Pectoralis minor (origin and insertion)

A

Origin: upper ribs
Insertion: coracoid process

27
Q

Deltoid (origin and insertion)

A

Origin: actomion proces and spine of scapula, clavicle
Insertion: humerus

28
Q

Pectoralis major (origin and insertion)

A

Origin: clavicle, sternum and costal carilage of ribs
Insertion: humerus

29
Q

Biceps Brachii (origin and insertion)

A

Origin: glenoid cavity and caracoid process
Insertion: radius

30
Q

Triceps Brachii (Origin and insertions)

A

Origin: 1 scapula, 2 humerus
Insertion: ulna

31
Q

Set up of the abdominal wall (superficial to deep) and why is contraction different

A
  1. External Oblique
  2. Rectus Abdominus
  3. Internal Oblique
  4. Transverse Abdominus
    *Contraction decreases volume of abdominal cavity and increases pressure
32
Q

Biceps Femoris (Origin and insertion)

A

Origin: femur and pelvis
Insertion: fibula and tibia

33
Q

Sartorius (Origin and insertion)

A

Origin: lateral anterior ilium
Insertion: medial tibia

34
Q

Quadriceps femoris (Origin and insertion)

A

Origin: Ilium and femur
Insertion: Patella

35
Q

Gastrocnemius (Origin and insertion)

A

Origin: femur
Insertion: Achilles tendon
