Answer 21

…..

Question 22

Papez circuit?

Answer 22

…..

Question 23

Where is it important?

Answer 23

The anterior thalamic nucleus plays a part in allowing us to bring infor from the hippocampus to the frontal cortex and ‘remember things’.

Also allows us to not go into fight or flight response all the time (Eg. burnt toast scenario)

Question 24

Internal capsule location

Answer 24

separates lenticular nucleus from the caudate nucleus

Question 25

Internal capsule structure

Answer 25

More medial aspects contain sensory firbres coming in and lateral aspects contain motor fibres heading out the the body

The bend is called the knee or GENU and the motor fibres heading to the face can normally be found here.
