11 and 12 meet a full facet at the superior body of T11 and T12, respectively

149
Q

Why don’t ribs 11 and 12 have costotransverse joints?

A

They do not articulate with transverse processes of thoracic spine

150
Q

What are the muscles of respiration?

A

Any muscles that have the ability to change the volume of the thoracic cavity - includes abdominal muscles

151
Q

Primary muscle of inspiration?

A

Diaphragm (elevates lower 6 ribs)

152
Q

What muscles are working during relaxed breathing?

Just the diaphragm

153
Q

A

True: #1-7
False: #8-10
Floating: #11-12

154
Q

What kind of joints are sternocostal?

A

Cartilaginous synchondrosis (amphiarthrotic, gliding)

155
Q

What are the 3 joints of the sternocostal joint?

A
Costochondral joint (rib and cartilage)
Chondrosternal joint (cartilage and sternum)
Interchondral joint (between cartilage of ribs 5-10)
156
Q

What are the 2 intrasternal joints?

A

Manubriosternal joint

Sternoxiphoid joint

157
Q

What is the common term for hyperlordosis?

A

Swayback

158
Q

The lumbar spine moves freely in all directions except…

A

rotation

159
Q

Why does the lumbosacral joint region not allow sagittal plane motions (flexion/extension)?

A

Because the facets have changed from sagittal to frontal orientation

160
Q

Why is the low back injured so often?

A

It needs a lot of stability for weight bearing, but it also allows for a lot of mobility

161
Q

When the lumbar spine performs lateral flexion, what motion is also produced?

A

Contralateral rotation

162
Q

What are the large sheets of fibrous tissue located in the trunk? Where are they located? Function?

A

Thoracolumbar fascia (posterior trunk) and abdominal aponeurosis (anterior trunk)

Functions: attachment sites for muscles; add stability

163

How many layers of thoracolumbar fascia?

A
  1. anterior
  2. middle
  3. deep
