what is the general organization of upper limb?
shoulder girdle (what is it called?; where is it between)
arm: between?
forearm: between?
hand: distal to what?
- pectoral girdle; b/w axial skeleton and shoulder joint
- b/w should joint and elbow joint
- b/w elbow joint and wrist joint
- distal to wrist joint
mnemonic: peck-to- RAL
what are origins
in terms of mobile
and term relationship
- less mobile
- and/or more proximal of a muscle’s attachment
mnemonic: poop doesn’t move
What are insertions?
- more mobile
- and/or more distal of the muscle’s attachment
mnemonic: dingo does move
what is the scapula
it is the shoulder blade
what is the coracoid process:
- what is another name?
- it is a major point of WHAT from WHAT
- it helps to shelter
- crow’s beak
2.weight/stress transfer;
arm to shoulder
- the superior aspect of the shoulder joint
what is in the proximal part of the shoulder joint and it receives what?
- glenoid cavity
- humeral head
mnemonic: glee-noid
scapular notch is crossed by 2 things?
- suprascapular artery and nerve
scapular spine divides what into what
- back of scapula
2. supraspinous and infraspinous fossae
acromion is what of the shoulder and distal end of what
- point
2. scapular spine
humerus head is what type of an enlarged part of WHAT that articulates with WHAT
- proximal
- humerus head
- glenoid (rhtym w/ annoyed) cavity
what is another name for intertubercular groove?
bicipital
what is another name for collar bone?
clavicle
rythms w/ tricycle
clavicle is a WHAT which DOES WHAT and WHY?
- strut
- keeps(Separates) upper limb from thorax
- to allow max mobility
the clavicle transmits and from who to who.
- force
2. from arm to axial skeleton
is clavicle is one of the most commonly fractured bones?
T
What is another name AC joint?
acromioclavicular
acromion + clavicle
the shoulder separation is tearing of HWAT connecting HWAT
what is this really?
- ligaments
- connecting the distal end of the clavicle to the lateral end of the scapula
- dislocation of AC joint
Pectoralis Major
- origin(3)
- insertion
- innervated by
- major actions(2)
- medial, 1/2 of clavicle, sternum and ribs 1-6(upper 6 ribs)
- upper anterior humerus
- medial and lateral pectoral nerves
- adduction and medial rotation of arm (double a)
pectoralis minor
- origin
- insertion
- innervated by
- stabilizes WHAT against WHAT
- allows a WHAT rotation of WHAT
- important landmark for what artery
- can function as what muscle of what
- ribs 3-5
- coracoid process of scapula
- medial pectoral nerve
- scapula; thoracic wall; 5.medial rotation of scapula
- axillary artery
- accessory of respiration
serratus anterior
- origin
- insertion
- innervated
- important in WHAT of WHAT by WHAT against WHAT
- required for WHAT in order to WHAT the arm beyond WHAT
- damage to WHAT or WHAT can cause WHAT
- ribs 1-8
- medial border of scapula
- by long thoracic nerve
- stabilization; scapula; holding it; thorax
- lateral scapular rotation; abduct ; beyond 90 degrees
- muscle; innervating nerve; scapular winging
scapula mnemonic: she cap sings la
which muscle attach the upper limb to the vertebral column?
- trapezius
- latissimus dorsi
- levator scapulae
- rhomboid minor
- rhomboid major
trapezius
- origin? (see trapezoid)
- insertion(3)
- innervated?
- does what 4 things to scapula?
- occipital bone and c7-t12 vertebral spines
- lateral 1/3 of the clavicle, acromion, and the scapular spine
- spinal accessory nerve(CN XI)
- elevates, depress, retract, rotates(ethan the robotic raccon)
Latissimus Dorsi
- origin?(3)
- insertion
- innervated?
- does what 3 things to humerus?
- t7-t12 vertebral spines, iliac crest, inferior ribs
- intertubervular groove
- thoracodorsal nerve
- extend, adducts, and medially rotates
mnemonic: “lady ismu dorsy”
elizabeth adore monkey roti
Levator scapulae
- origin?
- insertion 2
- innervated?
- does what 2 things to scapula?
- vertebrae c1-c4
- medial scapular border, above base of scapular spine
- dorsal scapular nerve
- elevate and medially rotates
mnemonic: evil mother…..
