Flashcards in Medulla Deck (12):
1

The medulla contains which ventricle?

4th

2

The pyramids are made of...

Corticospinal tracts that decussate in the inferior part

3

The olives are made of...

Inferior olivary nuclei that are associated with the cerebellum

4

The medulla is mainly involved in...

Movement, sensory processing and cognitive tasks

5

Damage to the medulla is associated with...

Decreased ability to perform highly specialised tasks

6

Inferior cerebellar peduncles

Two ridges carrying the olivocerebellar fibres which connect the cerebellum and the medulla

7

What are the prominences found either side of the midline in the fourth ventricle?

Medially - nucleus of the hypoglossal nerve
Laterally - nucleus of the vagus nerve

8

What are the four vertical ridges found posterior to the middle medulla?

Two medial - fasiculi grascilis
Two lateral - fasciculi cuneatus

9

Where are the gracile and cuneate nuclei usually seen on a Weigert?

Seen as pale clusters in a middle medulla section

10

Which cranial nerve nuclei are found in the medulla

X - vagus
XI - spinal accessory
XII - hypoglossal

11

Decussation of the pyramids

deviation in the anterior midline sulcus which corresponds to the decussation of 80% of pyramidal fibres to form the anterior and lateral corticospinal tracts

12

Where are the spinocerebellar tracts found?

in the lowest part of the medulla
