Q

Where does the inguinal ligament run?

A

from the pubic symphasis to the anterior superior iliac spine

17
Q

What does the pectoral girdle provide support for?

A

muscles of respiration, specifically muscles of inspiration

18
Q

What is in the pectoral girdle and what are its contents?

A

provides support for muscles of respiration, specifically the muscles of inspiration

scapula

clavicle

19
Q

What are the three parts of the sternum?

A

manubrium

body (corpus)

xyphoid process

20
Q

What are the three types of ribs?

A

True Ribs (1-7)

False Ribs (8-10)

Floating Ribs (11-12)

21
Q

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

A

central tendon

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

22
Q

What are the functions of the rib cage?

A

provide flexibility and protection

23
Q

What ribs are the true ribs?

A

Ribs 1-7

The costal cartilage of each rib articulates ventrally with the sternum

24
Q

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

A

Articulates ventrally with the sternum

25
What ribs are the false ribs?
Ribs 8-10 These do not directly communicat with the sternum
26
What ribs are the floating ribs?
11-12 The costal cartilage at the ends of these lower most ribs blend into the soft tissue of the chest wall ventrally
27
What are the features of the ribs?
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
28
What is the pubic symphasis?
Where the 2 pubic bones merge
29
What are the positions of the ribs?
Resting: downward sloping position Elevation: expantsion fo the chest wall
30
What are the dimensions that the ribs move when they are elevated?
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
31
What analogy do we have for lateral movement of the ribs?
Bucket-handle Rotational axis through the superior costal facet Transverse diameter (lateral) of teh thorax increases Rotates on the facets
32
What analogy do we have for anterior/posterior dimensional movement of the ribs?
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
33
What is the insertion point of the diaphragm?
Central Tendon
34
What is the Innervation of the Diaphragm
the frenic nerve, coming from the cervical plexus of C3-C5
