B
T/F
pectoris major lies superficial to pectoris minor
T
which muscle a superficial muscle that sweeps around the lateral aspect of the thoracic cage
A)pectoris minor
B)Pectoris major
C)Serratus anterior
C
Using muscles such as Pectoris maj
Pectoris min, Serratus anterior in breathing may indicate?
respiratory distress.
A patient arriving at A&E is using their accessory muscles of breathing. Which muscles are these, and what does this tell you about the patient?
Pectoris maj
Pectoris min
Serratus anterior
sternocleidomastoid
Respiratory distress
- Which lymph nodes are usually affected first by the spread of breast cancer and why
most lymph is drained from axillary nodes which contains 5 groups of lymph nodes
Most important group is apical (at apex of breast) since it receives lymph from the other collections of axillary nodes
axillary nodes are therefore usually first affected by metastases
