ANS - Exam 3

Neuroanatomy - ANS

Primary control center of ANS hypothalamus
ANS input from cortex is largely conveyed to hypothalamus via the amygdala
pupillary constriction centers in midbrain
micturition centers in pons
cardiac & pulmonary centers in medulla
heart afferents vagal & glossopharyngeal from carotid body & sinus to solitary nucleus
Pain with sympathetics T1-T4 on left
Control centers in medulla react to input from hypothalamus & baro- & chemo-receptors
Parasympathetics dorsal motor X
parasympathetics pass to ganglion cells
ganglion cells innervate primarily nodes slowing the heart
sympathetics T1-T4 reach heart directly from chain or ascending then descedning as cardiopulmonary splanchnic nn.
parasympathetics cause erection
sympathetics cause emission
somatic reflexes cause ejaculation
bladder pain travels with lumbar & pelvic splanchnics (ps) & ascends in the spinothalamic tract
bladder fullness in wall with ps to spinothalamic tract
bladder fullness in trigone with ps to dorsal columns
bladder parasympathetics cause contraction of internal urethral sphincter & relaxation of detrusor
bladder somatic motor fibers from the Onuf nucleus
Onuf nucleus contracts the external sphinter via the perineal branch of the pudendal n.
Bladder cerebral control centers are in the superior frontal gyrus
Bladder pontine centers contract the external urethral sphincter & relax the external uretheral sphincter & contract the detrusor
Bladder low level distension stimulates Onuf nucleus
High level distention inhibits Onuf nucleus & sympathetic
Parkinson's disease resting tremor
Parkinson's disease difficulty initiation movement
Parkinson's disease due to loss of dopaminergic neurons in substania nigra
Huntington's disease (Chorea) inability to stop moving
Huntington's diease (Chorea) due to genetic defect which causes cellular loss in the striatum (especially the caudate nucleus)
Hemiballismus flailing of limbs on 1 side
Hemiballismus due to damage to the subthalamic nucleus
