25
Latissimus dorsi
Large muscle which extends from the thoracic and lumbar vertebrae Helps pull the body upwards when climbing, draws shoulders/arm down and backwards
26
Errector Spinae
Runs down the length of the vertebrae Extends the spine and holds the body upright
27
Pectorals
Cover the chest Draws the arm and shoulder in towards the chest
28
Intercostals
In-between the ribs, running obliquely downwards Muscle of respiration, used to increase the thoracic cavity when breathing normally
29
Rectus abdominis (6 pack)
Extends the whole length of the front of the abdomen & is divided into 4 sections Flexes the trunk forwards, extends the spine and maintains upright posture
30
Obliques (corset)
Extends laterally from sides of the abdomen Flexes the trunk, when acting alone it twists the trunk
31
Diaphragm
Mid chest separating the thoracic and abdominal cavities Muscle of respiration, flattens to increase the thoracic cavity when breathing in, causing the ribs to rise
32
Quadriceps (rectus femoris, vastus lateralis, vastus medialis and vastus intermedius)
Front of thigh Flexes the hip and extends the knee
33
Adductors (longus, magnus and brevis)
Inner thigh Adducts the hip and rotates the hip
34
Abductors (Tensor fascia latae)
Outer / lateral thigh Flexes and abducts the thigh
35
Sartorius
Crosses the front of the thigh to the inner knee Flexes and laterally rotates the hip joint, used to sit cross legged
36
Tibialis anterior
Down the shin On the lateral side of the tibia Flexion and inversion of the foot (drawing sole inwards)
37
Gluteals
Buttocks Abducts and rotates femur, extends the knee
38
Hamstrings (biceps femoris, semimembranosis semitendonosis)
Back of thigh Extends the hip and flexion of the knee
39
Gastrocnemius
Back of calf Flexes the knee and the foot, used for propelling the body when walking
40
Soleus
Deep in the back of the calf, below gastrocnemius Flexes the foot
41
Deltoid
Caps shoulder Lifts, extends, and rotates the arm
42
Biceps
Front upper arm Flexes the forearm and turns palm upwards
43
Triceps
Back upper arm Extends the forearm
44
wrist flexors
Anterior forearm – comprises of 3 muscles Flexes the wrist, drawing it towards the forearm
45
Wrist extensors
Back of forearm – comprises of 3 muscles Extends and straightens the wrist and hand
46
Brachioradialis
Thumb side of forearm Flexes the elbow
47
Brachialis
Front of lower part of the upper arm, crossing the elbow Flexes the forearm
48
Body systems = Skeletal system
Bones / Joints Support / structure Movement Produces blood cells (red bone marrow) Mineral deposit Detoxification (stores toxic heavy metals)
49
Skull / cranuim
Protects brain
50
Spine
Several sections - Cervical (neck), thoacic (ribs), lumbar (lower back), sacrum, coccyx (tail) Facilitates movement Protects spinal chord
51
Ribs
Protect lungs Form thorax / thoracic cavity
52
Sternum
Breast bone
53
Pelvis
Supports reproductive organs 3 sections - ilium, ischium, pubis
54
Scapula

Found in fingers & toes
66
Joints
Most body joints are synovial - contain synovial fluid Several types of synovial joints - different planes of movement
67
Saddle joint
Thumb - rock back and forward and side to side (flexion and extension) but limited rotation.
68
Gliding joint
