What is the cauda equina?

Lower lumbar, sacral and coccygeal nerve roots that descend after conus medullaris

13

What is the filum terminale?

Thread of pia mater that attaches to coccyx

14

L3

16

Where is the inferior termination of subarachnoid space?

S2

17

Where is the superior termination of the subarachnoid space?

Superior sagittal sinus

18

Sacral hiatus (S5)

19

Where is the superior termination of the epidural space?

Foramen magnum

20

What does the subarachnoid space contain?

Cerebrospinal fluid

21

At which levels of the spinal cord is lateral grey horn present?

T1 to L2

22

At which levels of the spinal cord is cuneate fascicle present?

Above T6

23

At which levels of the spinal cord is gracile fascicle present?

All levels

24

Where is the gracile fascicle?

Medial part of dorsal white column

Which level of spinal cord has the most white matter and why?

Cervical
Because it contains axons travelling to the entire body

Which spinal cord levels have ventral grey horn enlargements and why?

Cervical and lumbar
Accumulation of motor neurons for innervation of limbs
