regions of the brain
2 hemisperes split saggitally
How many hemisperes does the brain have
What is the cerebrum/functions?
protective layers of the brain
what is the Meninges?
Group of structures in both cerebral hemispheres and diencephalon
what is the limbic system
the stalklike part of your brain that connects your brain to your spinal cord (column of nerve tissue that runs down your spine). It sits toward the bottom of your brain and is part of your central nervous system.
What is th brain stem/functions?
Has outer cortex of gray matter (neural bodies & dendrites)
What is the Cerebral Hemispheres?
Contains primary motor cortex; controls most body movement
Important for planning, conscious thought, decision-making, reasoning and sequencing areas speech/language production
Prefrontal area for memory
What is the Frontal lobe/funtions?
Cell bodies
What is gray matter made up of?
involved inbasic emotions related to survival and the processing of emotions such as fear, anger, problem resolution, mental conflicts, and pleasure; determines which memories are stored and where they are stored in the brain.
What is the Amygdala/functions?
the smallest portion of the brainstem and its most cranial structure. vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation, acting as a sort of relay station for auditory and visual information.
what is the midbrain/functions?
Midbrain, pons, medulla oblongata
what is the brain stem
sits behind the ears and is the second largest lobe. most commonly associated with processing auditory information and with the encoding of memory(long term)
What is the temporal lobe/functions?
Axons
What is white matter made up of?
a region of the forebrain below the thalamus which coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity
What is the Hypothalamus/functions?
Helps to maintain normal rhythm of breathing
Erratic breathing may be injured or damaged pons
What is the pons/functions?
Has outer cortex of gray matter
What is the Cerebellum?
Input from Optic nerve-Contains primary visual cortex
- processes visual information
most is on surface inside central fissur -Outputs to parietal and temporal lobes
What is the optic lobe/functions?
Dura Mater - Arachnoid Layer -Sub Arachnoid space (CSF)-Pia Mater-Gray Matter-White Matter
what are the Layers from Exterior to Interior of the meniges?
What is the hippocampus/functions?
Most inferior part of the brain stem
Adjusts the force and rate of heart beat and depth of breathing
Regulates vomiting, hiccupping (spasm of the diaphragm), swallowing, coughing and sneezing
What is the Medulla Oblongata/functions?
Thalamus, hypothalamus, and epithalamus
Center, deeper region
What is the Diencephalon
What is the parietal lobe/functions?
Inflammation (swelling) of the protective membranes covering the brain and spinal cord
What is meningities?
A rounded mass of tissue that contains several types of nerve cells that are involved in the sense of smell. located on the bottom side of the brain, one above each nasal cavity.
What are the olfactory bulbs/functions?
Why is the brainstem so important?
