Week 1 - Neuro anatomy

Question 1

Cerebrum

Answer 1

what you picture for “brain”
largest part of the brain
divided by deep grooves (2 halves)
two halves communicate with each other

Question 2

cerebral cortex

Answer 2

gray matter, outter most layer of brain

Question 3

corpus callosom

Answer 3

thick track of nerves at base of fissures
how the hemispheres communicate

Question 4

fissure

Answer 4

deep grooves
divide brain into hemispheres

Question 5

messages to and from the body and the brain are handled by …

Answer 5

Opposite sides (left vs right)

Question 6

Frontal lobe

Answer 6

located in front of the central sulcus
deals with:
executive function, reasoning, planning, organization, problem solving, emotion regulation, impulse control, sustained attention, short term memory, parts of speech/language, and motor movement

Question 7

Central Sulcus

Answer 7

thick band that separates the frontal and parietal lobes

Question 8

Parietal Lobe

Answer 8

located below the lateral fissure
concerned with: perception and processing of sensory information –> auditory stimuli (hearing) and memory (hippocampus), taste, pain, texture, and temp.

Question 9

Temporal Lobe

Answer 9

located behind the central sulcus
hearing, language, memory, emotion

Question 10

Broca’s area

Answer 10

located towards frontal lobe

Question 11

Wernicke’s area

Answer 11

located towards the temporal lobe (behind Brocas)

Question 12

Occipital Lobe

Answer 12

Located at the back of the brain –> behind temporal and parietal lobe
understanding and processing visual images and connecting them to the images stored in memory (why we can recognize images when we see them)
also visual-motor planning

Question 13

Cerebellum

Answer 13

combines sensory information from the eyes, ears, and muscles to help coordinate movement

Question 14

brainstem

Answer 14

links brain to the spinal cord
Vital to life: heart rate, blood pressure, breathing and sleep

Question 15

Limbic system (midbrain)

Answer 15

thalamus
hypothalamus
hippocampus
basil ganglia
amygdala

Question 16

Thalamus

Answer 16

“gate keeper” for messages passed between the spinal cord and the cerebrum
all info from senses travels through it before being sent to “brain” to interpret
“relay station”

Question 17

Hypothalamus

Answer 17

controls emotions, regulates body temp, and controls functions such as eating or sleeping

Question 18

hippocampus

Answer 18

sends memories to be stored in ares of cerebrum and also recalls memories later on

Question 19

Basil Ganglia

Answer 19

processes information on movement and then has the brain tell you the best possible response to a given situation;
if someone throws a ball up –> you catch it
if someone kicks a ball to you –> you kick it back
(which action to respond to movement)

Question 20

Amygdala

Answer 20

mediates aspects of emotion and memory;
used to only be thought to be involved in fear and unpleasant emotions; but now we know that it is also associated with positive emotions elicited by rewarding stimuli
