Answer 1

-Strataum zonale
-external medullary lamins
-Divided by internal medullary lamina

Question 2

Answer 2

Anterior part
Medial part
Lateral part

Question 3

Explain the anterior part of the thalamus:
-WHt does it contain
-Where it recieves info from
-Function

Answer 3

• Contains Anterior thalamic nuclei
  -Recievs info from mamillothalamci tract
  -Emotion and recent memory

Question 4

Explain the medial part of the thalamus:
-What is the main nucleus
-What is the function :
what does it integrate+ link

Answer 4

-Main nucles: dorsomedial nucleus
Function; integrates sensory info + links to emotion and subjective feelings

Question 5

Explain the lateral part of the thalamus:
-What is it divided into + explain the components in the second one + functioms
-What does the 1 part contain+ what is it connections

Answer 5

-Dorsal tier and ventral tier
Ventral tier :
-Ventral anterior nucleus- Motor infleunce
-Ventral lateral nucleus- Motor coordination
-Ventral posterior nucleus: divided into
-VPM) Ventro postermedial) + VPL (ventro posterolatera)

Dorsal tier contains: lateral dorsal,lasteral posterior,pulvinar

connections: pariteal, occipital, temporal lobes

Question 6

What is the function fo the Ventro posteromedial (VPM) and Ventro posterolatera)

Answer 6

Process sensory information from the head

Question 7

Nsme other thalamic nuclei

Answer 7

Intralaminar
-Midline nuclei?
Reticular nucleus
-relay nucleus

Question 8

Answer 8

Alterness and consciousness

Question 9

-Function
-where it recieves input from
-Its ouput

Answer 9

• Relays auditory
• inpur: inferior colliculus
• Output- auditory radiation which goes auditory cortex

Question 10
