FINAL REVIEW PACK COMPLETE QUESTION
SET AND CORE CONCEPT SUMMARY
◉ Which of these is slower and more long-term: Endocrine or
Nervous system? Answer: - Endocrine
◉ Where is the brain stem located? Answer: - Encased by cervical
vertebrae in the neck
◉ What makes up the Brain Stem? Answer: - Medulla Oblongata
- Pons
- Midbrain
◉ Where is the medulla oblongata located? What is it involved in?
Answer: - Right above spinal cord
- SOME involuntary activities (breathing, heart rate, swallowing,
sneezing, vomiting, tears, righting reflex)
,◉ What is the oldest part of the brain? Answer: - Medulla oblongata
◉ What are nuclei? Answer: - Collections of nerve cell bodies with a
common function
◉ What are vegetative functions? What controls most of these?
Answer: - Basic functions needed to survive (respiration, heart rate,
swallowing), without them you're on life support
- Medulla oblongata
◉ What is the Righting Reflex? Answer: - Proprioception that allows
our body to keep track of our spatial configuration
- We naturally prefer to be upright
◉ What are "Pyramids"? Answer: - Crossing over of nerve tracts
◉ T/F: The right side of the brain controls the right side of the body,
and the left side of the brain controls the left side of the body
Answer: - False, the right controls the left and the left controls the
right
,◉ What is the pons involved in? What's another name for the pons?
Answer: - Relay center between cerebrum (thought) and cerebellum
(motor/motion)
- Relay between PNS and center control
- Also controls respiration
- AKA the "Bridge"
◉ What is the midbrain involved in? What's another name for the
midbrain? Answer: - Controls eye movements
- Takes in vision/auditory input
- AKA "Mesencephalon"
◉ What is the RAS? What is it involved in? Answer: - Reticular
Activating System
- Activates the body/makes it conscious or wakes it up
- Keeps you alert
, - Communicates to all higher areas in the brain
◉ Is arousal/sleep gradual or all at once? Generally describe how
sleep works? Answer: - Gradual
- RAS wakes you up in increments
- You don't suddenly fall asleep, it happens in 4 stages (4 = REM)
◉ Where is the reticular formation located? Answer: - Right outside
medulla oblongata
◉ What two conditions can result from problems with the RAS?
Answer: - Narcolepsy (RAS randomly shuts down)
- Insomnia (trouble falling asleep)
◉ What is an EEG? Answer: - Electro encephalogram
- Put electrodes all over the skull and measure electrical signals and
patterns in the brain
