The Amazing Wonders of the Brain Flashcards
1
Q
3 Primary Divisions of the Brain
A
Forebrain, Midbrain, Hindbrain
2
Q
Forebrain Parts
A
Cortex (Cerebral Hemispheres, Corpus Callosum)
Basal ganglia
Limbic system
3
Q
Midbrain Parts
A
Amygdala
Hippocampus
Thalamus
Olfactory bulbs
Hypothalamus
*sensory and motor functions
4
Q
Hindbrain Parts (Lower)
A
Medulla
Pons
Cerebellum
Reticular Formation
5
Q
- Controls life-sustaining functions: heartbeat, breathing, swallowing
- Great damage = death
- First “swelling” located at the top of spinal column
- Sensory nerves coming from left & right cross over, left info goes to right brain vv
A
Medulla
6
Q
- ____ means “bridge” between cerebellum and upper brain sections
- Crossover of motor nerves information
- Left-right body movement coordination
- Sleep, dreaming, arousal
- Larger “swelling” above the medulla, big bump in the brain stem
A
Pons
7
Q
- Network of neurons running through the middle of the medulla and the pons
- Selective attention, alertness to change in information
- Implicated in comas in humans
A
Reticular Formation
8
Q
- Stimulates the upper part of the brain, keeping people alert and awake
- Car swerving in front of you, mother hearing her baby cry at night
A
Reticular Activating System (RAS)
9
Q
- Controls all involuntary, rapid, fine motor movement, posture, balance (walking, skating, dancing, musical instrument)
- Reflexes, skills, habits (automatic)
- Little brain: base of the skull, behind pons
A
Cerebellum
10
Q
- Damaged cerebellum: tremors, unsteady walk, slurred speech, dizziness, muscle weakness
- Unable to walk, stand, move spoon
A
Spinocerebellar degeneration
11
Q
Influence motor control and learning motor skills
A
Basal ganglia
12
Q
Cognitive and emotional processing
A
Cingulate cortex
13
Q
Limbic
A
“Limbus” or margin
14
Q
Limbic system (Midbrain)
A
Amygdala
Thalamus
Hypothalamus
Hippocampus
Cingulate Cortex
Olfactory bulbs
15
Q
“Inner chamber”
A
Thalamus
