Neuroanatomy

Question 1

Limbic Cortex:

Answer 1

• Involved in processing emotions and some types of memory

Question 2

Insular Cortex:

Answer 2

• Autonomic visceral functions and taste

Question 3

Thalamus:

Answer 3

• Relay station
• Receives information from basal ganglia, cerebellum and all sensory systems except olfactory; processes the information, relays the selected information to the specific areas of the cerebral cortex

Question 4

Relay Nuclei:

Answer 4

• Convey information from the sensory systems, the basal ganglia, or the cerebellum to the cerebral cortex
• All relay nuclei are found in the ventral tier of the lateral group

Question 5

Association Nuclei:

Answer 5

• Process emotional and some memory information or integrate different types of sensation
• Found in the anterior thalamus, medial thalamus, and dorsal tier of the lateral thalamus

Question 6

Nonspecific Nuclei:

Answer 6

• Regulate consciousness, arousal, and attention
• Receive multiple types of input and project to widespread areas of cortex; this includes reticular, midline, and intralaminar nuclei

Question 7

Cerebellum:

Answer 7

• Primary site of coordination
• Called little brain
• Connects to the brainstem via peduncles
• Cerebellar lesions affect ipsilateral function
