Flashcards in Sacrococcygeal Joint Deck (20):
1

What joint classifications are present at the sacrococcygeal joint?

- cartilaginous (amphiarthrosis) symphysis
- fibrous (amphiarthrosis) syndesmosis

2

What is different about the intervertebral disc of the sacrococcygeal joint?

it is a true fibrocartilage similar to the symphysis pubis but lacks the nucleus pulposus, annulus fibrosus, and cartilage end plates of intervertebral discs

3

What lig represents the continuation of the anterior longitudinal lig at the sacrococcygeal joint?

the anterior sacrococcygeal lig

4

What are the attaching sites for the anterior sacrococcygeal lig?

the vertebral bodies form about S3 to Co2-Co3

5

List in order from cranial to caudal the ligs forming the anterior boundary of the spinal column.

- anterior atlanto-occipital lig
- anterior atlanto-axial lig
- anterior longitudinal lig
- anterior sacrococcygeal lig

6

What lig represents the continuation of the posterior longitudinal lig at the sacrococcygeal joint?

the deep posterior sacrococcygeal lig

7

What are the attaching sites for the deep posterior sacrococcygeal lig?

the vertebral bodies from about S3 to Co1

8

List in order from cranial to caudal the ligs forming the anterior boundary for the spinal canal.

- membrana tectoria
- posterior longitudinal lig
- deep posterior sacrococcygeal lig

9

What lig represents the homolog of the ligamentum flavum at the sacrococcygeal joint?

the superficial posterior sacrococcygeal lig

10

What are the attaching sites for the superficial posterior sacrococcygeal lig?

the medial margins of the sacral hiatus and sacral cornu down to the back of the vertebral body of Co1

11

List in order from cranial to caudal the ligs forming the posterior boundary of the spinal canal.

- posterior atlanto-occipital lig
- posterior atlanto-axial lig
- ligamentum flavum
- superficial posterior sacrococcygeal lig

12

What forms the closure for the spinal canal inferiorly?

the fusion of the deep posterior sacrococcygeal lig with the superficial posterior sacrococcygeal lig

13

What is the homolog of the intertransverse lig at the sacrococcygeal joint?

the lateral sacrococcygeal lig

14

What are the attaching sites for the lateral sacrococcygeal lig?

the inferior lateral margin of sacrum and the transverse process of Co1

15

What is the homolog of the capsular lig at the sacrococcygeal joint?

the intercornual lig

16

What are the attaching sites for the intercornual lig?

the sacral cornu and the coccygeal cornu

17

What does the sacral cornu represent?

the inferior articular process and facet of S5

18

What does the coccygeal cornu represent?

the superior articular process and facet of Co1

19

What common ligs are represented at the sacrococcygeal joint?

- anterior longitudinal lig
- posterior longitudinal lig
- intervertebral disc
- ligamentum flavum
- capsular lig
- intertransverse lig

20
