Q

Infraspinatus

A

O: Infraspinous fossa
I: greater tubercle of humerus (middle facet)
N: suprascapular nerve
F: laterally rotates arm

17
Q

Subscapularis

A

O: subscapular fossa
I: lesser tubercle of humerus
N: upper and lower subscapular nerves
F: adducts and medially rotates arm

18
Q

Long Head of Triceps Brachii

A

originates from infraglenoid tubercle

19
Q

Teres Major

A

O: lateral border of scapula (lower half and inferior angle)
I: anterior side of humerus (medial lip of intertubercle groove)
N: lower subscapular nerve
F: extends and medially rotates arm

21
Q

Shoulder Spaces (general)

A

blood supply and innervation to the shoulder muscles pass anterior to the shoulder joint through spaces to supply muscles located posterior to the shoulder joint.
3 spaces: the quadrangular space, the triangular space, and the triangular interval.

22
Q

Shoulder Vessels

A

quadrangle space- axillary nerve and posterior circumflex humeral vessels
triangular space- circumflex scapular artery (posteriorly)
triangular interval- radial nerve and deep artery of arm (profunda brachii)
suprascapular notch- suprascapular vessels and nerve- artery passes superficial to transverse scapular ligament, nerve passing deep

23
Q

Latissimus Dorsi

A

O: spinous processes of lower thoracic and lumbar verebrae, iliac crest, sacrum
I: intertubular groove of the humerus
N: thoracodorsal nerve
F: extends adducts and medially rotates humerus

24
Q

Serratus Anterior

A

O: Upper ribs (typically 1-8)
I: Medial border of the scapula (anterior side)
N: Long thoracic nerve
F: Protracts and laterally rotates scapula

25
Q

Pectoralis Major

A

O: Clavicular head: medial ½ of clavicle
Sternocostal head: sternum and adjacent costal cartilages
I: Anterior side of humerus (lateral lip of intertubercular groove)
N: Medial and Lateral pectoral nerves
F: Flexes, adducts and medially rotates arm

26
Q

Pectoralis Minor

A

O:Ribs 3-5
I: Coracoid process of scapula
N: Medial pectoral nerve
F: Depresses scapula and assists with protraction

27
Q

Deltopectoral Groove

A

clavi- deltopectoral triangle

lies between medial border of anterior deltoid and lateral edge of pectoralis major

28
Q

Cephalic Vein

A

blood returning from upper extremity to heart

lies within deltopectoral groove

29
Q

Collateral Circulation

A

arterial blood can reach it via multiple routes
often has anastomoses
helps prevent ischemia
common around joints

30
Q

Collateral Circulation for Scapula

A

through dorsal scapular artery or through suprascapular artery to connect with circumflex scapular artery

31
Q

Quadrangular Space

A

It is bounded by:
above/superior: the subscapularis and teres minor.
below/inferior: the teres major
medially: the long head of the triceps brachii
laterally: the surgical neck of the humerus

allows axillary nerve and posterior circumflex humeral vessels (artery and vein) to pass

32
Q

Triangular Space

A

It is bounded by:
the teres major inferiorly
the long head of the triceps laterally
For the superior border subscapularis

contains circumflex scapular artery

33
Q

Supraspinatus

A

O: Supraspinous fossa
I: greater tubercle of humerus (superior part)
N: suprascapular nerve
F: abducts arm (also responsible for initiating abduction)

34
Q

Triangular Interval

A

Two of its borders are as follows:
teres major - superior
long head of the triceps brachii - medial
lateral border- humerus

contains radial nerve and deep artery of the arm (profunda brachii)

35
Q

Long Thoracic Nerve (innervates)

A

serratus anterior

36
Q

Dorsal Scapular Nerve (innervates)

A

rhomboids and some levator scapulae

37
Q

Suprascapular Nerve (innervates)

A

supraspinatus and infraspinatus

38
Q

Median Branch (innervates)

A

(C5-T1) to most of the muscles of the anterior (flexor) forearm and 5 intrinsic muscles of the hand

39
Q

Ulnar Branch (innervates)

A

(C8-T1) to 1 1/2 muscles in the anterior (flexor) forearm and all the remaining intrinsic muscles of the hand

40
Q

Radial Branch (innervates)

A

(C5-T1) to all posterior (extensor) muscles of the arm and forearm; many have significant effects in the hand

41
Q

Musculocutanous Branch (innervates)

A

(C5-C7) to the three muscles of the anterior arm
