Basic Neuroanatomy

Question 1

Parietal Lobe

Answer 1

32

• Somatosensory Cortex
• Gustatory Cortex
• Parietal Association Cortex
• Visiomotor Orientation
• Attention
• Representation of Space

Question 2

Thalamus

Answer 2

13

• Mojor sensory relay nuclei for inputs into the cerebral cortex.
• Nuclei involved in basal ganglia-cortical loops and other specialized nuclear groups.

Question 3

Occipital Lobe

Answer 3

34

• Visual information processing

Question 4

Superior and Inferior Colliculi

Answer 4

7

• Superior - Receives input from the retinal system, playing a role in visuomotor processes. May also play a role in inhibitory reflexive attentional orientation.
• Inferior - Involved in auditory processes.

Question 5

Midbrain

Answer 5

3

• Visual - Superior colliculus, oculomotor nucleus, trochlear nucleas, etc
• Auditory - Inferior colliculus
• Motor coordination - Mesencephalic tegmental nuclei

Question 6

Cerebellum

Answer 6

4

• Maintains interconnectivity between various structures.
• Plays a role in various aspects of coordination ranging from locomotion to skilled movement.

Question 7

Medulla

Answer 7

1

• Various sensory and motor nuclei
• Relays somatosensory information from the spinal cord to the brain (gracile and cuneate nuclei).
• Ventral pyramidal tracts (descending projection axons from brain to spinal cord).

Question 8

Pons

Answer 8

2

• Vast system of fiber tracts interspersed with pontine nuclei - continuations of cortical projections to the spinal cord, brainstem, and cerebellar regions.
• Primary sensory nuclear groups for auditor and vestibular inputs.
• Somatosensory inputs from and motor nuclei to the face and mouth.

Question 9

Pituitary Gland

Answer 9

16

• Helps maintain homeostasis.

Question 10

Hypothalamus

Answer 10

Area between #18 and #22​

• Important for the function of the autonomic nervous system and the endocrine system.
• Controls functions important for maintanence of homeostasis.

Question 11

Nucleus Accumbens

Answer 11

Cortical area to the right of #22

• Part of the basal ganglia
• Associated with the reward system and changing activity due to reinfocers.

Question 12

Corpus Callosum

Answer 12

23

• Bundle of axons connecting the two hemipheres of the cortex.

Question 13

​Frontal Lobe

Answer 13

31

• Contains the prefrontal cortex and the motor cortex.

Question 14

Cingulate Gyrus

Answer 14

30

• A part of the limbic system responsible for emotion and behavior regulation.
