Brain Anatomy

Question 1

Grey Matter

Answer 1

Neuron cell bodies are organized into these sections, where neural processing occurs

Question 2

White Matter

Answer 2

bundles of myelinated axons connecting regions within the brain or spinal cord

Question 3

Cortex

Answer 3

Outer region of the brain (mostly gray)

Question 4

gyri

Answer 4

ridges

Question 5

sulci

Answer 5

grooves

Question 6

Cerebrum

Answer 6

higher-order processing. In humans its responsible for sensory perception, learning, language, memory, and conscious behavior

Question 7

corpus callosum

Answer 7

axons connecting the right and left cerebral hemispheres

Question 8

Thalamus

Answer 8

filters and relays sensory information to the cerebrum

Question 8

Cerebellum

Answer 8

Fine-tune motor control by comparing outgoing motor commands with sensory information about the actual ongoing movements achieved

Question 9

Hypothalamus

Answer 9

Regulation of homeostatic set points including temperature regulation, thirst, hunger, etc

Question 10

Brainstem

Answer 10

Contain centers vital to control of respiration, cardiovascular regulation, and digestive tract (e.g. swallowing vommitting)

Question 11

Midbrain

Answer 11

coordinates reflex responses to sight (brainstem)

Question 12

Pons

Answer 12

Regulates non conscious functions like breathing and sleep cycle (brainstem)

Question 13

Medulla Oblongata

Answer 13

Where brain and spinal cord connect, helps regulate things like heartbeat and breathing (brainstem)

Question 14

Olfactory bulb (two)

Answer 14

Receives signals from olfactory receptors. Tracts carry information from here to regions of the brain that process smell
