up - abdo part,
horiztonal -sternocostal part and
downwards - clavicular part - Actions - shoulder adduction / medial rotator [ Arm flexion (clavicular head), arm extension (sternocostal head)]

Can change the height and length of the arm / position hand in space
[Superior rad / ulnar - Rotation allows effective positioning]

Stretch superficialis / profondus?
Flexor digitorm superficalis - extend wrist + fingers [pressure on middle finger biases superficalis] - note FDS attaches to the middle phalanges of 2-5 mets
Flexor digitorum profundus - extend wrist + fingers [ pressure on end of finger biases prfondus] note this is where FDP attaches, the distal phalanges of the fingers 2-5
ROM C spine flex extend?
Flexion / extension: 130 in total, 100 from neurtral - chin to chest
Identify two ligaments associated with the joints of Thumb or fingers.
Metacarpophalangeal joints / Carpometacarpal strengthened by: collateral ligs and Palmer ligs
You collide in to ollie palmer - snaping his finger ligaments
attachments biceps / triceps
Morphology - Fusiform, 3 Heads (long head, medial head & lateral head)
O- Infraglenoid tubercle (Long Head)
Lateral side (lateral head), of posterior surface of humerus medial side (medial head) of posterior surface of humerus
I-Olecranon process
An infared beam of light shines on glencoe which prevents lattitude from happening in a medevil castle so ole has to cancel his ticket
Action-
Extension of elbow and shoulder
Nerve - Radial
====
Morphology - Fusiform, 2 Heads (short head and long head)
O- Supraglenoid tubercle (Long Head) Corocoid Process (Short head)
I-Radial Tuberosity
[+bicipital aponeurosis into deep fascia on medial part of forearm]
Super man jumps off glencoe and catches corona virus so jumps in a radioactive tube to get rid of it
Action-
Flexion of elbow and shoulder
Supinator of forearm
Nerve - Musculocutaneous
Route of musc / ax nerve?
see video
greater / lesser tubicle / intertubecular sulcus attachements?
Greater - other rotator cuff muscles
Lesser Tubercle: subscapularis
intertubercular sulcus: lat dorsi, pec majjor , biceps tendon is in this region
surface mark GH joint
coracoid process - lat third of clav then down
Then a laterally and then down 3cm

Adductors:
Pec Major
Lat dorsi
Teres major muscle
degrees ROM at elbow? / end feel

Flexion: 140°-160°
Extension: 0° (up to 10° hyperextension)
End feel
Flexion: soft (soft tissue bulk)
Extension: hard (olecranon in olecranon fossa)
Nerve pecs
pectoral nerve
pecs attachments
(1) - Clavicular part: anterior surface of medial half of clavicle

(3) - Abdominal part: Anterior layer of rectus sheat
Insertion
(1) - Crest of greater tubercle of humerus (lat dorsi inserts inbetween pec major / teres major)
Test the end feel for flexion/extension/abduction and identify the limiting factors GH

Coracobrachials actions?
GHJ flexion / adduction
End feel radial deviation?
hard
Erectus spinae
A
Morph:
- Large complex muscle
- Head down to sacrum
- Located on the posterior side of the trunk
Actions: EXTENSION of the spine, helps with side flexion / rotation
- Longissimus (middle) - level of transverse process - capitis / cervisis / Thoracis / Lumborum
- Ilieocostalis (lateral) - level of rib cage - cervisis, thoracis, Lumborum
- Spinalis (medial) - level of spinous process - capitis, cervisis, thoracis
(ie throaccic spine, cervial , lumbar..)
O: Sacrum, iliac crest, spinous process T11-L5
I: Ribs, all transverse processes, mastoid process (behind the ear)
Santa filling his sac full of rum (1) on the moons crest (2) when he spins around 11 Times (3) and Laughs 5 times (3) so much so that he falls off the moon into a restraunt, he orders ribs (4 ), meets a transexual (5) and maturbates (6) before ramming his nob in the door and breaking his spine (nerves)
Distal / inferior radio ulnar joint – classification, movements, ART, structures ect.. 4 points
- Classification - synovial pivot joint
