VAN - vein on top, artery, nerve on bottom

26
Q

Costochondral joint

A

rib to cartilage - no movement

27
Q

Sternocostal joint

A

1st rib is primary cartilaginous joint, rest are synovial plane-type joints

28
Q

Sternoclavicular joint

A

between sternum and clavicle; synovial, saddle-type joint

29
Q

Manubriosternal joint

A

immovable - between sternal body and manubrium

secondary cartilagenous joint

30
Q

Xiphisternal joint

A

primary cartilagenous joint - immovable

between xiphoid process and body of sternum

31
Q

Male breast is located

A

in 4th intercostal space

32
Q

Female breast is located in

A

superficial fascia, is a modified sweat gland
1/3 sits on serratus anterior and 2/3 sits on pectoralis major
vertically from 2nd to 6th ribs, transversely from lateral border of sternum to mid-axillary line

33
Q

Lactiferous ducts

A

open onto the nipple

34
Q

Pectoralis Major

A

O: lateral border of sternum upper 6 costal cartilages, clavicle
I: lateral lip of interubercular sulcus of humerus
N: medial and lateral pectoral nerves (on deep surface)
A: flex, adduct, and rotate arm medially
B: pectoral branch of thoraco-acromial artery

35
Q

Pectoralis Minor

A 
Deep to P. major
O: outer surface of ribs 3-5
I: Coracoid process of scapula
N: Medial pectoral nerve
B: Pectoral branch of thoraco-acromial trunk
A: lowers lateral angle of scapula
36

A

O: lateral surface of upper 8-9 ribs
I: costal surface of medial border of scapula
N: Long thoracic nerve
B: Lateral thoracic artery (on superficial surface of muscle)
A: protracts scapula, holds it against thoracic wall

37
Q

Retromammary Space

A

between lactiferous glands and deep fascia, allows movement of breast

38
Q

Suspensory (Cooper’s) ligament

A

attaches gland to dermis of skin, well developed superiorly

If breast tumor grows here, will pull suspensory ligament in and dimples skin

39
Q

Vasculature to breast

A

Internal thoracic a., lateral thoracic a., and pectoral branches of thoracoacromial trunk

40
Q

Levator Costarum

A

Transverse processes C7-T11 to costal tubercle and costal angle

A

between ribs, innervated by local intercostal nerves (ventral primary ramus of spinal nerve)
11 intercostal spaces

42
Q

External intercostal muscle

A

Elevates ribs
Fibers run anteroinferiorly from upper to lower rib
starts at costal tubercle, runs to costochondral junction
Extends to sternum as external (anterior) intercostal membrane

43
Q

Internal intercostal muscle

A

starts anteriorly
Costal (bony ribs) portion depresses
Chondral (costal cartilage) portion elevates
Fibers run posteroinferiorly from upper to lower rib
Muscle starts at lateral border of sternum, runs to costal angle
Extends to vertebrae as internal (posterior) intercostal membrane

elevates ribs
located in third muscular layer of intercostal space
found internally on poserolateral thoracic walls

45
Q

Subcostal muscle

A

located internally on posterior thoracic wall
crosses more than one intercostal space
elevates ribs
located in third muscular layer of intercostal space posteriorly

46
Q

Transversus thoracics

A

Depresses ribs
Lower sternum to internal surface of 2nd to 6th costal cartilage
Located in third muscular layer of intercostal space anteriorly

47
Q

Parietal pleura

A

lines internal thoracic cavity external to the pulminary pleura, covers diaphragm
attaches to thoracic muscles via endothoracic fascia

48
Q

Neurovascular bundle

housed in the costal groove between the second and third muscular layers

49
Q
