Lecture 29 (Thoracic Spine I)

Question 1

least mobile and most stable part of the spine?

Answer 1

thoracic spine - bc of thoracic spine and attachment to ribs and sternum

Question 2

diaphragm attachments

Answer 2

Xiphoid
Internal surface of inferior 6 ribs
Left crus= L2
Right crus= L3

Question 3

Costal facets of 1st, 10th, 11th, and 12th ribs:

Answer 3

usually have a complete costal facet on upper edge for articulation with rib heads

Question 4

costal facets ribs (2-9),

Answer 4

costal facets are shared by 2 adjacent vertebrae so most thoracics have half-facets situated at both upper and lower borders of body

Question 5

On anterolateral surface of transverse process of upper ten thoracics are

Answer 5

costal facets for articulation with the rib tubercles

Question 6

Superior facets in the lumbar and cervical spine-

Answer 6

Backward, Upward and Medial

Question 7

Main Lymphatic duct

Answer 7

• Originates from the cisterna chyli in the abdomen and ascends through the aortic hiatus in the diaphragm
• Lies anterior to bodies of the 7 inferior thoracic vertebrae
• Duct crosses to left at T4, T5 or T6 posterior to the esophagus
• Enters the junction of the left internal jugular and left subclavian vein

Question 8

Thoracic duct

Answer 8

• Largest lymphatic channel in the body
• Receives lymphatic drainage from lower limbs, pelvis, abdomen, left upper limb, and left side of thorax, neck, head
• Thoracic duct directly related to thoracic inlet (future lecture

Question 9

Right lymphatic duct drains lymph from…

Answer 9

ONLY from the right upper quadrant of thorax

Question 10

Parasympathetics from where?

Answer 10

cranial-saral

Question 11

Sympathetics from where?

Answer 11

THORACOLUMBAR distribution (T1- L2 or 3)

Question 12

if history of sufficient trauma, severe tenderness, deformities, etc do what?

Answer 12

xray and or neurologic eval

Question 13

Structural exam of the thoracic spine

Answer 13

• Step One: Screen to the area of dysfunction using the sweep
• Step Two: localize to the general area using landmarks
• Step Three: localize to the specific level with the rule of three’s
• Step Four: finalize the diagnosis: assessing for either Type I or Type II SDs.

Question 15

T4-T6 - finding TP

Answer 15

Question 17

T10: - finding TP

Answer 17

SPs at the level of the TPs one segment below

Question 18

T11 - finding TP

Answer 18

SPs halfway between that level’s TPs and the one below

Question 19
