Forebrain, midbrain, hindbrain 1 of 24 What are the two main structures of the diencephalon? Thalamus and Hypothalamus 2 of 24 What is the largest portion of the diencephalon? Thalamus 3 of 24 In terms of locality, what part of the diencephalon is the thalamus? Most Dorsal 4 of 24 What connects the two lobes of the thalamus? Bridge of Massa intermedia 5 of 24 What nuclei act as a relay station for non sensory information? Ventrolateral nuclei 6 of 24 What information does the lateral geniculate nucleus and medial geniculate nucleus relay? Sensory 7 of 24 What does the ventrolateral nucleus do? Relays info from cerebellum to primary motor cortex 8 of 24 What does the medial geniculate nucleus do? Relays auditory information from the inner ear, to the auditory cortex 9 of 24 What does the lateral geniculate nucleus do? Relays visual information from the eyes, to the primary visual cortex 10 of 24 Where is the hypothalamus located, in terms of diencephalon locality? Ventral part 11 of 24 What attaches the pituitary gland to the hypothalamus? Pituitary stalk 12 of 24 What are the two main loves of the pituitary gland? Anterior and posterior 13 of 24 Which pituitary gland is considered the "master" gland? Anterior pituitary gland 14 of 24 How does the anterior pituitary gland interact with hormone secretion? Indirectly via hormones 15 of 24 How does the posterior pituitary gland interact with hormone secretion? Directly via synaptic transmission 16 of 24 What is the HPA axis? The stress response 17 of 24 What nucleus secretes CRH? Paraventricular nucleus 18 of 24 What is CRH? Corticotropin Releasing Hormone 19 of 24 What stimulates the anterior pituitary gland to release adrenocorticotropic hormone (ACTH)? CRH : Corticotropin Releasing Hormone 20 of 24 In the HPA axis, what does the ACTH stimulate when it enters the blood? The adrenal cortex to release cortisol 21 of 24 What have rat studies shown about cortisol and epigenetics? Nurturing rat mothers = offspring resilient to stress 22 of 24 How does the hypothalamus affect the posterior pituitary gland? It produces the posterior pituitary hormones and directly controls their secretion. 23 of 24 The hypothalamus controls the anterior pituitary gland via... Hormones 24 of 24
