Remember This
What is memory?
This disability damages myelin, interrupting neural impulses.
What is multiple sclerosis?
The brain and the spinal cord make up this system.
What is the central nervous system?
60% of the brain is composed of this.
What is white matter?
This structure is located in the lower back of the brain and about the same size as a fist.
What is the cerebellum?
The amygdala houses emotional memories and the cerebellum houses this type of memories.
What are procedural memories?
The speed of impulse transmission does this as more layers of myelin are wrapped around an axon.
What is increase?
This system contains structures that focus on basic functions necessary for survival.
What is the limbic system?
This is the percentage of sensory information being filtered out by the thalamus.
What is 99?
This is the place where unconscious reflexes are controlled.
What is the spinal cord?
This is composed of sensory memory and working memory.
What is short-term memory?
These cells wrap around axons creating layers of cell membrane that make up myelin insulation.
What are glial cells?
The limbic system is composed of these four structures.
What are the thalamus, hypothalamus, amygdala, and hippocampus.
The brain consumes approximately this percentage of overall calorie intake.
What is 20%?
What is the brain stem?
These three factors increase long-term retention.
What are frequency, intensity, and duration?
The speed of impulse transmission slows when this thins, or decreases in thickness.
What is myelin?
A coma can be the result when this system is damaged.
What is the reticular activating system?
Myelin is a fatty sheath made of 80% lipids and 20% of this.
What is protein?
The amygdala is located deep within this portion of the brain.
What is the temporal lobe?
Physical and chemical changes occur each time the brain stores this.
What is new information?
People begin to lose myelin in this area during their senior years, slowing down cognitive processes and making learning more difficult.
What is the cerebral cortex?
This part of the limbic system holds immediate memories
What is the hippocampus?
The cerebellum accounts for 10% of the brains volume but over 50% of these.
What are neurons?
This part of the brain secretes hormones that regulate internal parts of the body.
What is the hypothalamus?
