Week 6 (test 3) Flashcards
What is the fornix tract responsible for?
connects the hippocampus to the mammillary bodies
hippocampus –> fornix –> mammillary bodies –> mammillothalamic tract –> anterior and dorsal thalamus
What is the dorsal longitudinal fasciculus responsible for?
major output for parasympathetic ANS control from the paraventricular nucleus
What is the hypothalamospinal tract responsible for?
major output for sympathetic ANS control from the paraventricular nucleus
What is the median forebrain bundle responsible for?
connects the ventral tegmental area, amygdala, hypothalamus, striatum (nucleus accumbens), and cortex
involved in the reward system
What is the suprachiasmatic nuclei (SCN) responsible for?
master circadian clock
What are the Preoptic anterior nucleus (POA) and posterior nuclei responsible for?
Control thermal regulation via antagonistic interactions
What is the Paraventricular nucleus (PVN) responsible for?
master regulator of ANS control and endocrine (neuro and adeno) control
What is the Dorsomedial nucleus (DMH) responsible for?
Integrates circadian rhythms, energy consumption, feeding and body weight to regulate ANS functions including cardiac and blood pressure responses and interacts with the PVN to reduce glucocorticoid release for energy regulation.
What is the ventromedial nucleus responsible for?
acts as a satiety center
What are the mammillary bodies responsible for?
Aids conversion of memory from short- to long-term; target of the fornix.
Describe the process of thermoregulation inculing the peroptic anterior nucleus, posterior nuclei, the paraventricular nuclui, and the dorsal longitudinal fasciculus. Also discuss how PGE2 affects this cycle
Describe the pathway for melatonin secretion
