This autonomic function increases digestive motility, decreases heart rate, and constricts the pupils
This autonomic function increases heart rate and vasoconstriction, decreases digestive motility, and is responsible for pupil dilation, piloerection, and sweat gland secretions
The _________ and _________ nuclei send axons down through the infundibular stalk via the supraopticohypophyseal tract.
oxytocin, antidiuretic hormone (ADH)
The Supraoptic and Paraventricular nuclei are both capable of releasing what two substances?
The supraoptic and paraventricular nuclei send axons down through the infundibular stalk via the __________________ tract
Suprachiasmatic Nuclei (SCN)
Responsible for our circadial (daily) 24-25 hour rhythms such as temperature, sleep, light, feeding, etc. Complexly connected to the pineal gland.
Near the infundibular stalk of the intermediate area, contributes axons to the tuberoinfundibular tract.
anterior pituitary, releasing factors

The loss of short-term memory from alcohol...associated with the mammillary bodies.
A thermoregulator; especially as the body cools down...stimulating shivering (piloerection)
Tracts that includes the Supraopticohypophyseal tract and tuberoinfundibular tract...
Which area gives rise to the anterior pituitary (adenohypophysis) and intermediate pituitary?
internal carotid arteries
Most blood to the pituitary and its infundibular stalk comes from the branches off the ___________
Within the infundibular stalk the small arteries break into highly permeable capillaries called ____________
hypophyseal portal veins
