Central Control of ANS Flashcards
What two plexuses does the ANS control
Myenteric plexus, Submucosal plexus
What organ facilitates the control of emotional states
Hypothalamus
Electrical stimulation of the floor of the 4th ventricle will produce increases
BP, HR, peripheral vasoconstriction, secretion of E
Stimulation of the brain stem controls
Reflexes & vital automatic functions : “Vital Centres” Control of the Circulation & Heart,
Respiration & Lungs,
Swallowing
Stimulation of the Hypothalamus
controls
Global and interdependent functions,
Control of
Thermal & Nutritive economies, Neuroendocrine regulation,
Behavioural activities, appetite, relating to reproduction
Stimulation of the Limbic System controls
Signs & symptoms associated with emotional experience and expression
The midbrain controls
Periaqueductal grey matter: ANS responses to painful stimuli
The Pons controls
Parabrachial nucleus: respiratory & cardiovascular control
The Medulla controls
N. Tractus solitarius: afferents from cardiac, respiratory & GI receptors
Ventrolateral m. area : Control centre for sympathetic preganglionic neurones
The Brain Stem controls
Vital centres important for ANS functioning
What is vitrification
Defaecation
What root values are responsible for mitrification
S2, S3, S4
Where is the inhibitory area located for the mitrification process
Midbrain
Where are the facilitatory areas for the Mitrification process
Pons, Posterior, Hypothalamus
True or False, During the mitrification process, the detrusor muscle relaxes and the urethral sphincter contract
False, it’s the other way around
