Brain
STUDY
PLAY
main divisions of the brain
medulla, pons, midbrain, diencephalon, cerebellum & cerebrum
thalamus function
Relay station for afferent sensory information through connections with the cortex, and plays an important part in sensory, motor, and cognitive functions.
hypothalamus function
hormone secretion, autonomic effects, thermoregulation, food and water intake, rythm of sleep ad waking, memory, emotional behavior
sensory information is processed and relayed to the cerebrum by the
thalamus
what provides the principal link between the nervous and endocrine systems
infundibulum
autonomic centers that control blood pressure, heart rate, and digestion are located in the
medulla oblongata
cerebrospinal fluid
bathes the brain and spinal cord and acts as a shock absorber that protects the central nervous system
the white matter of the cerebellum forms the
arbor vitae
limbic system components
amygdala, limbic lobe, cingulate gyrus, dentate gyrus, parahippocampal gyrus, hippocampus, fornix
The anterior nuclei of the thalamus
control emotion and motivation
the highest levels of information processing occur in the
cerebrum
the two cerebral hemispheres are separated by
longitudinal fissure
divisions of the cerebral hemispheres that are named after the overlying skull bones are
lobes
the cerebral area posterior to the central sulcus is the
parietal lobe
the superior border of the temporal lobe is marked by the
lateral sulcus
the corpus callosum is composed of
commissural fibers
within each hemisphere, deep to the floor of the lateral ventricle, you will find the
basal nuclei
damage to the substantia nigra causes a decrease in the neurotransmitter dopamine; this causes a gradual, generalized increase in muscle tone, which is the main symptom of
Parkinson's disease
the primary motor cortex is the surface of the
precentral gyrus
the visual cortex is located in the
occipital lobe
the auditory cortex is located in the
temporal lobe
the sense of taste projects to the gustatory cortex located in the
anterior insula and frontal lobe
cortical regions that interpret sensory information or coordinate motor responses are called
association areas
the region of the brain responsible for predicting the consequence of events or actions is the
prefrontal cortex
the cardiovascular reflexes are based in the
medulla oblongata
