Field of Medicine Medicine Program Lecture : (Autonomic Nervous System 2 ) Dr : (Mohamed Talal) Date : 13/10 /2024 functions of sympathetic nervous system on abdomen : Liver: glycogenolysis ( hyperglycemia ). increase metabolic rate. increase fibrinogen synthesis ( limit bleeding ). functions of sympathetic nervous system on abdomen : Pancreas: Stimulates glucagon secretion. inhibits insulin secretion. functions of sympathetic nervous system on abdomen : Adrenal medulla: secretion of 80% adrenaline – 20% noradrenaline. Adrenaline Noradrenaline Greater effect on : Greater effect on Cardiac contractility ( β1) arterial blood pressure ( VC via α1 ) functions of sympathetic nervous system on abdomen : Gastrointestinal tract: Inhibition ( relaxation ) of wall. contraction of sphincters. functions of sympathetic nervous system On pelvis : Rectum: (retention of feces) inhibition of wall. contraction of internal anal sphincter. functions of sympathetic nervous system On pelvis : Urinary bladder: (retention of urine) inhibition of wall. contraction of internal urethral sphincter. functions of sympathetic nervous system On pelvis : Male genitalia: Ejaculation.
