What are the three types of ribs and their corresponding numbers?

True (vertebrocostal) ribs: 1-7
False (vertebrochondral) ribs: 8-10
Floating (free) ribs: 11-12

1

Passive expiration

Muscles relax, intrathoracic volume decreases, and intrathoracic pressure increases, intra-abdominal pressure decreases

2

Passive inspiration

Muscles contract, intrathoracic volume increases, and intrathoracic pressure decreases, intra-abdominal pressure increases

3

"Pump handle movement"

Anteroposterior (AP) dimension - anterior ends of ribs and sternum (especially inferior end) rise like a pump handle

4

"Bucket-handle movement"

Transverse dimension - thorax increases slightly raising the most lateral parts of the ribs (especially the most inferior ones)

5

Vertical dimension

Increases during inspiration and the diaphragm descends and returns to normal position during expiration

6

Intervertebral joint type

Secondary cartilaginous

7

Costovertebral joint type

Synovial plane

8

Costotransverse joint type

Synovial plane

9

Sternocostal joint type

1st rib: primary cartilaginous (synchondrosis)
2-7th ribs: synovial plane

10

Sternoclavicular joint type

Synovial saddle

11

Costochondral joint type

Primary cartilaginous (synchondrosis)

12

Interchondral joint type

Synovial plane

13

Manubriosternal joint type

Secondary cartilaginous (symphysis)

14

Xiphisternal joint type

Primary cartilaginous (synchondrosis)

15

What are the two openings of the inguinal canal?

Deep (internal) ring and superficial (external) inguinal ring

16

Manubrium alignment with vertebrae

T3-T4

17

Sternal angle alignment with vertebrae

Intervertebral disc of T4 and T5

18

Body of the sternum alignment with vertebrae

T5-T9

19

Xiphoid process alignment with vertebrae

T10

20

What are the main constituents of the spermatic cord?

Ductus deferens, testiculary (gonadal) artery and vein, cremaster muscle, and genital branch of genitofemoral nerve

21

What runs under the costal groove of the rib?

Intercostal VAN (inferior border) which then splits into the collateral VAN (superior border of rib below)

22

Sacroliliac joint

Anterior - synovial
Posterior - syndesmosis

Movement = slight gliding and rotary movement

23

Pubic symphysis

Secondary cartilaginous (symphysis)

24

Lumbosacral joint

1. Intervertebral joint
2. Zygapophysial (facet) joint

25

Sacrococcygeal joint

Secondary cartilaginous (symphysis)

26

Typical ribs

3-9th

27

Atypical ribs

1, 2, 11, and 12
