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
