  1. First ribs & costal cartilage

  2. Manubrium 

  3. Body of T1 vertebrae

300

What are the origins & insertions of the levator ani muscles?

  1. Levator Ani:

    1. Origin: Pubis, Internal obturator fascia (Tendinous arch)

    2. Insertion: Anococcygeal ligament, coccyx

300

What are the origins & insertions of the respiratory diaphragm? 

It attaches to:

  1. Sternal part: Xiphoid process

  2. Costal part: Inner surfaces of ribs 7–12

  3. Lumbar part: L1–L3 vertebral bodies via crura (tendinous anchors)

The respiratory diaphragm is the only muscle in the body that possesses this unique relationship to the sagittal plane

What is "crossing the midline?"

300

Name three cylindrical structures that travel through the inferior thoracic inlet

Caval opening (T8) – for the inferior vena cava

Esophageal hiatus (T10) – for the esophagus & vagal nerves

Aortic hiatus (T12) – for the aorta

400

The relationship between thoracic volume and intrapulmonary pressure is proportional or inverse, and why? 

  1. What is inverse? As volume increases (air rushes in), pressure drops, which helps us pull air in from the outside. Air wants to move from high pressure places to low pressure ones.
