3

what are the divisions of the mediastinum

superior and inferior mediastinum. This is between t4 and T5

4

what separates the inferior from the superior mediastinum

the transthorracic plane

5

how many sections of the inferior medistinum are there? What are they

anterior, middle and posterior mediastinum

6

what does the thorax communicate with

the neck

7

superior aperture of the thorax is also known as

thorracic outlet

8

what is the anteiror boarder of the thorax

upper border of the manubrium

9

sibsons fascia

10

there is a chance that you could puncture the lungs

11

a person is stabbed in the neck, is there a chance that thier lungs can be damaged

yes

what is a cervical rib

transvrse process extends posteriorly

13

what is thorracic inlet syndrome

transverse process of c7 extends laterally and compresses lower trunk of bracial plexus and subclavian artery

14

what are symptoms of thorracic inlet syndrome

vascular compromise of the upper limb due to subclavian artery

diminished radial pulse
Unilateral - dif in pulse b/n R and L limbs. Bilateral difference in Femoral pulse

neural pressure on lower trunk causes pain down medial forearm hand and wasting of muscles

15
