manubrium

body (corpus)

xyphoid process

Question 20

What are the three types of ribs?

Answer 20

True Ribs (1-7)

False Ribs (8-10)

Floating Ribs (11-12)

Question 21

What is the insertion of the diaphragm and what nerve innervates it? ?

Answer 21

central tendon

phrenic nerve, from the cervical plexus (C3- C5)

Question 22

What are the functions of the rib cage?

Answer 22

provide flexibility and protection

Question 23

What ribs are the true ribs?

Answer 23

Ribs 1-7

The costal cartilage of each rib articulates ventrally with the sternum

Question 24

Where does the costal cartilage articulate for the true ribs (1-7)

Answer 24

Articulates ventrally with the sternum

Question 25

What ribs are the false ribs?

Answer 25

Ribs 8-10 These do not directly communicat with the sternum

Question 26

What ribs are the floating ribs?

Answer 26

11-12 The costal cartilage at the ends of these lower most ribs blend into the soft tissue of the chest wall ventrally

Question 27

What are the features of the ribs?

Answer 27

head: articulates with the thoracic vertebrae, 2 at a time Neck Tubercle: posterior surface, 3rd articulator point with thoracic vertebrae adn touches the transverse process Angle Shaft (body): biggest part of hteh rib Costal End: ventral end, ends by the sternum

Question 28

What is the pubic symphasis?

Answer 28

Where the 2 pubic bones merge

Question 29

What are the positions of the ribs?

Answer 29

Resting: downward sloping position Elevation: expantsion fo the chest wall

Question 30

What are the dimensions that the ribs move when they are elevated?

Answer 30

In a lateral dimension Anterior posterior dimension This creates a space in the anterior and poster ior directsion and a space laterally with the chest wall

Question 31

What analogy do we have for lateral movement of the ribs?

Answer 31

Bucket-handle Rotational axis through the superior costal facet Transverse diameter (lateral) of teh thorax increases Rotates on the facets

Question 32

What analogy do we have for anterior/posterior dimensional movement of the ribs?

Answer 32

Pump handle Rotational xis through the superior and inferior costa facets ribs are more forward and upward with the sternum Helps to show that there is more space to be gained from the lower ribs when there is a lateral movement

Question 33

What is the insertion point of the diaphragm?

Answer 33

Central Tendon

Question 34

What is the Innervation of the Diaphragm

Answer 34

the frenic nerve, coming from the cervical plexus of C3-C5
