6.0 neuro - diencephalon Flashcards
what are the regions of the diencephalon
epithalamus (pineal gland, habenula), thalamus (dorsal thalamus), hypothalamus, ventral thalamus (subthalamus)
what kind of information passes through the thalamus
all sensory information prior to cortex except olfaction
what is the largest part of the diencephalon
dorsal thalamus
connections of the dorsal thalamus
motor, sensory and limbic cortex, reticular activating system of the brain stem
where is the thalamus
midline structure w two hemispheres
what is the thalamus
relay center for all incoming motor and sensory (not smell) information
what are the main functions of the hypothalamus
control of the pituitary gland, control of the autonomic nervous system and a variety of survival behaviors (eating, drinking, sleeping, sexual behavior, parental behavior, aggression)
what is the function of paraventricular nuclei
produce oxytocin and vasopressin
what is the function of supraoptic nuclei
produce oxytocin and vasopressin
where are oxytocin and vasopressin released
onto the capillaries of the posterior pituitary
how does the hypothalamus control the anterior pituitary
secreting release factors into the hypophyseal portal system
what is the function of suprachiasmatic nuclei
regulate circadian rhythms
pathway of information for circadian rhythms
retina, suprachiasmatic nuclei, paraventricular nuclei, intermediolateral cell columns, superior cervical ganglia, pineal gland, melatonin secretion
what is thermoregulation
maintenance of core body temperature
function of the posterior nucleus
heat conservation
