Question 14

Superior to inferior order of intercostal vessels

Answer 14

intercostal verin artery nerve inferior to upper rib.
Superior to rib below is collateral branches.

These are sandwiched between innermost layer of intercostal muscle internal.

Question 15

internal thoracic artery

Question 23

Two big branches bifurcating from the SVC

Answer 23

left and right brachiocephalic vein which are in turn fed by hemiazygos veins draining from intercostal veins

Answer 25

anterior, middle, posterior.

Question 26

What demarcates inferior and superior mediastinum

Answer 26

T4 sternal angle

Question 27

Describe the rib

Answer 27

The typical rib consists of a head, neck and body: The head is wedge shaped, and has two articular facets separated by a wedge of bone. One facet articulates with the numerically corresponding vertebrae, and the other articulates with the vertebrae above. The neck contains no bony prominences, but simply connects the head with the body. Where the neck meets the body there is a roughed tubercle, with a facet for articulation with the transverse process of the corresponding vertebrae. The body, or shaft of the rib is flat and curved. The internal surface of the shaft has a groove for the neurovascular supply of the thorax, protecting the vessels and nerves from damage.

Question 28

Describe rib 1

Answer 28

Rib 1 is shorter and wider than the other ribs. It only has one facet on its head for articulation with its corresponding vertebrae (there isn’t a thoracic vertebrae above it). The superior surface is marked by two grooves, which make way for the subclavian vessels.
