Exam 2 Flashcards
What is the most rigid part of the vertebral column?
*Thoracic spine Facet joints
How is the thoracic spine aligned?
*In a mild kyphosis
What is the resting position of the thoracic spine/facets?
*Midway between flexion and extension (upright posture)
What is the closed pack position of the Thoracic spine?
Extension
What is the capsular pattern of the Thoracic spine?
*side flexion and rotation equally limited, extension
What is the mobile platform for thoracic movement?
- Thoracic Spine Facet Joints
- Upper extremities via ST and SC joints
- Cervical Spine
What does the sternum (breast bone) made up of?
- Manubrium, body, Sternum
* Sternal Notch of the Manubrium
What does the manubriosternal joint (sternal angle) align with?
*2nd rib
What does the xiphosternal joint align with?
- T9 vertebrae
* T7 ribs
What does the xiphoid process align with?
- T9 vertebra
* T6 dermatome
What is the norm for the infrasternal angle and what is the cause of a large or small one?
- Norm: 90 dg
- > 90 dg: tightness in internal obliques
- < 90 dg: tightness in external obliques
Would an upper chest breather have a larger or smaller angle?
*Less than 90 dg because they don’t expand the lower ribs
What can be palpated in the anterior ribs?
*Costochondral Junctions
How do you palpate the first rib?
*Posterior while sitting and/or prone
What are the characteristics of ribs 2-12?
- Most rounded inferior rib felt anterolaterally is the 10th rib and it’s costochondral junction
- Inferior and posterolateral to that is the tip of rib 11, ending just anterior to mid-axillary line
- Rib 12, inferior and medial to rib 11, it is about an inch or so below rib 11 about 2-4 inches from the spinous process
Which ribs have angles and where are they found?
- Ribs 2-10 have them
- 1st rib doesn’t possess an angle and 11th and 12th are slight if present
- 3-4 cm lateral to the tips of the transverse process
