1

Prosencephalon becomes

Telencephalon > Cerebrum Diencephalon > Thalamus and Hypothalamus

2

Mesencephalon becomes

Midbrain

3

Rhombencephalon

Metencephalon > Pons and Cerebellum

Myelencephalon > Medulla

4

Ascending Pathways are

Somatosensory

5

2 Ascending pathways 

  • Spinothalamic Tract
  • Dorsal Column Medial Leminiscus (DCML)

6

Spinothalamic Tract is responsible for 

Pain and Temperature 

7

Spinothalamic fibres decussate at

Spinal cord 

8

A lesion in the spinothalamic tract would cause 

Contralateral loss of pain and temperature 

9

Spinothalamic tract is 

Anterior 

10

DCML Pathway is responsible for 

Fine touch, pressure and vibration

11

DCML fibres decussate in 

the medulla 

12

A lesion in the DCML pathway would cause 

ipsilateral loss of fine touch, pressure and vibration sensations

13

DCML pathway is 

Posterior 

14

DCML is split into 

  • Fasciculus cuneatus: Upper limbs and trunk
  • Fasciculus gracilis: Lower limbs and trunk

"You stand with grace"

15

Fasiculus Cuneatus ends at 

T6

16

Descending pathways are 

Somatomotor 

17

2 main descending pathways 

  • Pyrimidal (Corticospinal, Corticobulbar)
  • Extrapyrimidal (Reticulospinal, Rubrospinal)

18

Pyramidal Tracts are 

Anterior

19

Extrapyramidal tracts are 

Anterior 

20

Corticospinal tract is split into 

  • Lateral corticopsinal tract 
  • Anterior corticospinal tract 

21

Lateral Corticospinal tract is responsible for 

Voluntary motor control of the limbs and digits

22

Lateral corticospinal fibres decussate in the 

Medulla (pyramidal decussation)

23

A lesion in the lateral corticospinal tract would cause 

Weakness in ipsilateral limbs and digits

24

Anterior corticospinal tract is responsible for 

Voluntary motor control of the trunk (maintains posture)

25

Corticobulbar tract is responsible for 

Motor control of the muscles of the face, head and neck

26

Corticobulbar tract is associated with 

Cranial Nerves 

27

Rubrospinal tract

controls flexion in the upper limbs 

 

"RuBROspinal as they are bicep curling"

28

Origin of rubrospinal tract is in the 

red nucleus (in the midbrain)

29

Reticulospinal tract 

excites extensor muscles 

30

Decerebrate posture

  • Extension of all upper and lower limbs 
  • Pronation of the wrist
  • Damage to brain, including midbrain

"You De-celebrate because they are dead, or look like it"
