1

Which sections of the spinal cord demonstrate Lordosis?

Cervical and Lumbar

2

What sections of the spinal cord demonstrate Kyphosis?

Thoracic, Sacral

3

1) not important

2) Body

3) Lamina

4) Superior Articular Process

5) Transverse process

6) Spinous Process

7) Body

8) Vertebral foramen

9) Costal facet

10) Lamina

4

What structure does the spinal cord pass through in the vertebrae? 

 

Vertebral foramen 

5

State the branching process of a spinal nerve, using the 8th cervical nerve as an example. Start with the anterior and posterior roots.

  • The anterior and posterior roots emerge from the spinal cord
  • The posterior (sensory) root then gives rise to the spinal ganglion
  • The anterior root then merges with the ganglion, merging to form the spinal nerve
  • The spinal then seems to give off a branch which is the posterior rami of the spinal nerve, leaving the main major part of the nerve which is the Anterior Ramus of the spinal nerve

6

Underneath what sturcture of the vertebral body would you expect the dorsal and ventral ramus to fuse

The Pedicles

7

What type of joint is between the articular facets of the spinal cord?

Synovial

8

State the number of spinal nerves for each section

Cervical 8

Thoracic 12

lumbar 5

Sacral 5

Coccygeal 1

9

Which group of spinal nerves travel OVER their respective spinal vertebrae?

Cervical

10

What group of spinal nerves travel under their respective vertebrae?

T, L, S, Co.

11

What structure deliniates the spinal cord from the brain?

The medulla

12

What vertebrae are the typical marks for a new-born infant with regards to the end of the spinal cord?

  • L3/L4

13

Where does the spinal cord end (vertebrally) in an adult?

L1/L2

14

What embyrological structure is the precusor to the dorsal horn in the spinal cord?

  • Alar plate

15

What embyrological structure is the precusor to the ventral horn?

Basal Plate

16

The butterfly shape in the spinal cord is which matter?

The GREY matter

17

The part of the spinal cord that surrounds the butterfly is what matter?

White matter

18

The grey matter has 3 divisions - also known as horns. State them

Posterior

Intermediate

Anterior

19

State the function of the neurones in the anterior spinal cord

Motor function

20

State the function of the neurones in the posterior grey horn

Sensory

21

State functions of the neurones in the lateral horn

Sympathetic funcion and parasymapthetic function

22

What is the name of the white matter between the dorsal horns?

Dorsal funniculus

23

What is the function of dorsal funniculus?

Primarily contains sensory pathways - those associated with light touch and pressure

 

24

What is the functin of the lateral funiculus?

Primarily contains the motor pathways

25

What is the function of the ventral funiculus?

Primarily motor but also pain and temperature pathways

26

Which region of the spinal cord has the largest ratio of grey to white matter?

Sacral

27

At which level does the spinal cord display a lateral lorn adjacent to the intermediate horn?

Thoracic

28

State the layers of meninges from most superficial to deep

Dura mater

Arachnoid Mater

Pia Mater

29

State the two main functions of the meninges

- Mechanical support

- Framework for blood vessels.

30

The dura mater has two layers - state them

  • Periosteal layer
  • meningeal layer
