16
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
Q

What ribs are the false ribs?

A

Ribs 8-10

These do not directly communicat with the sternum

26
Q

What ribs are the floating ribs?

A

11-12

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

27
Q

What are the features of the ribs?

A

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
Q

What is the pubic symphasis?

A

Where the 2 pubic bones merge

29
Q

What are the positions of the ribs?

A

Resting: downward sloping position

Elevation: expantsion fo the chest wall

30
Q

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

A

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
Q

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

A

Bucket-handle

Rotational axis through the superior costal facet

Transverse diameter (lateral) of teh thorax increases

Rotates on the facets

32
Q

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

A

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
Q

What is the insertion point of the diaphragm?

A

Central Tendon

34
Q

What is the Innervation of the Diaphragm

A

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