Main bronchi

15

Which cranial nerves are stimulated in coughing and sneezing?

Sneezing - CNV and CNIX
Coughing- CNIX and CN X

16

Describe the course of the phrenic nerves through the neck and chest

Descend through the neck on the anterior surface of the scalenus anterior muscle and then descend through the chest on the lateral aspects of the fibrous pericardium, anterior to the lung root

28

What is the linea semilunaris and what is the linea alba?

Linea semilunari - where muscle meets aponeurosis
Linea alba - where aponeurosis meets aponeurosis (midline)

29

what are some of the functions of the abdominal wall muscles?

Tonic contractions - posture and support of the vertebral column
Guarding contractions- protects abdominal viscera
Contractions - forced expiration
