Heart rate
Medulla oblonga
Body temperature
Hypothalamus
Posture
Cerebellum
Ongoing body movement
Basal nuclei of cerebellum
Relaying incoming signals to the cerebrum
Thalamus
Creates memories
Cerebrum
Stores and receives memories
Hippocampus
The sleep/wake cycle
Pineal gland
Your motivation to complete this study guide
Limbic system
Speech
Broca’s/ werniche’s
Vision
Cerebrum/ occipital lobe
Problem solving
Frontal lobe
Hunger pains
Hypothalamus
Septum pellucidum
Separates left and right lateral ventricles
Corpus callosum
Connects left and right cerebral hemi’s
Vermis
Separates left and right cerebellum hemi
Arachnoid granulation
absorption of CSF
Choroid plexus
Production of CSF
Amygdala
Emotions
Prefrontal cortex
Link consequence with action and emotion
Somatic nerve
Senses/ incoming
Motor nerve
Movement outgoing
Mixed nerve
Both directions
Duda mater
Outermost menignge
Dural fold
Infolding of dura
Spinal tap
CSF removed from subarachnoid space around cord
Epidural block
Anthemic added to epidural space
damaged amgydala
No emotion
Motor
Speech area
Cannot speak clearly but can understand
Interpretation area
cannot understand complex commands can speak
Cerebellum
No balance or coordination
Basal nuclei in the mesencephalon
Parkinson’s trouble continuing a motion
Olfactory nerve
Can not smell
Facial nerve, causing it to swell
Bell’s palsy, paralysis on one side, usually reversible over time
Prefrontal cortex
No time sequence or consequence for actions
Pineal glands
Odd sleep/ wake cycle bad circadian rhythm
Corpus callosum
Servere retardation, little or no communication between the hemi’s
What would decreased diffusion across the arachnoid granulation affect the volume of CSF in the ventricles
CSF volume increases, puts pressure on brain- hydrocephalus results
Many water-soluble molecules that are relatively abundant in the blood occur in small amounts or not at all in the extracellular fluid of the Brian. Why?
BBB only lets lipid-based substances pass through the ependymal layer of cells that envelop the cups
The medulla oblongata, if damaged can cause death, whereas similar damage in the cerebrum may go unnoticed. Explain
M.o. Controls vitals and lack will kill you
What exact causes the pain when you have a headache? Why are migraine headaches so intense
Headaches are due to scalp pain referred by neck m. Dehydration
Migraines- more intense cause scalp pain
Why are females better at multitasking when compared to males
Females have a wider
Corpus, and can coordinate the cerebral hemi more effectively as compared to males
At what age does the brain too growing larger
Stops growing around 4 and begins to shrink at 55
Blood pressure
Medulla oblonga
