Hypotalamic Function And The ANS Flashcards
What and where is it and what is its function (hypothalamus)?
Autonomic epicenter
Cluster of nuclei
Receives input from limbic, brainstem, visual, circulatory, CSF
Outputs to cerebral cortex, brainstem, spinal cord, endocrine
What is its relationship with the pituitary gland (hypothalamus)?
Hypothalmaus has direct and indirect routes
Direct: posterior pg (vasopressin and oxytocin)
Indirect: anterior pg, hypophyseal portal system (median eminence to infundibular stalk to apg)
What are the clinical manifestations of damage to the hypothalamic and pituitary structures?
Pituitary adenoma
What is the relationship between the hypothalamus and the limbic system?
How does the hypothalamus receive the input it needs to regulate bodily functions?
What are the differences between the sympathetic and parasympathetic components of the ANS?
What are the major parasympathetic nuclei that are influenced by the hypothalamus and what are their functions?
What is the sympathetic circuitry?
What is the autonomic innervation to the pupil?
What are the autonomic afferent connections and how does their circuitry explain referred pain?
How do autonomic control centers work to synergize the parasympathetic and sympathetic components of various processes like pupillary function, respiration and cardiac function?
