Chapter 3 Flashcards
autonomic nervous system
half of PNS
controls self regulated actions of internal organs and glands
2 parts: sympathetic and parasympathetic
basal ganglia
forbrain
a group of structures linked to the thalamus in the base of the brain and involved in coordination of movement
brainstem
controls the flow of messages between the brain and the rest of the body
controls basic body functions such as breathing, Midbrain. Pons. Medulla Oblongata
central nervous system
brain and spinal cord
central sulcus
separating the parietal lobe from the frontal lobe
cerebellum
hindbrain
balance
cerebral cortex
the outer layer of the cerebrum, composed of folded gray matter
important role in consciousness
cerebrospinal fluid
clear, colorless body fluid found in the brain and spine
produced in ventricles of the brain
acts as a cushion or buffer for the brain’s cortex protection to the brain inside the skull
computerized axial tomography
CAT scan
inject color into blood and take xrays
corpus callosum
a broad band of nerve fibers joining the two hemispheres of the brain
cranial nerves
Allow the medulla to control sensations from
the head, muscle movements in the head,
and many parasympathetic outputs
electroencephalograph
EEG
records electromagnetic activity
best temporal resolution
evoked potentials
recorded from the nervous system following presentation of a stimulus
detected by EEG
forebrain
most prominent part of brain, with two cerebral hemispheres outer portion is known as the “cerebral cortex” thalamus hypothalamus cerebral cortex hippocampus
frontal lobe
executive, motor, working memory, personality
speech production
*speech and language
fMRI
Functional magnetic resonance imaging
oxygen consumption in the brain provides moving, detailed picture
comparison tasks are used
**best spatial pictures
gray matter
layered (6)
each layer serves different function
hindbrain
medula, pons, cerebellum
hippocampus
forms part of the limbic system and is primarily associated with memory and spatial navigation
temporal lobe
