Sympathetic + Parasympathetic Nervous Systems Flashcards
Strengths + accelerates heartbeat
Heart in sympathetic nervous system
Skin + viscera blood vessels in sympathetic nervous system
Constrict arteries
Raises blood pressure
Heart, lung + skeletal muscle blood vessels in sympathetic nervous system
Dilate arteries to allow more blood flow
Digestive tract in sympathetic nervous system
Slows down peristalsis to decrease digestion
Urinary bladder in sympathetic nervous system
Relaxes the bladder wall
Bladder and anal sphincters in sympathetic nervous system
Causes contraction
Bronchial tube muscles in sympathetic nervous system
Muscles relax to dilate air passages for easier breathing
Iris muscles in sympathetic nervous system
Radial muscles contract to dilate the pupil
Sweat glands in sympathetic system
Increases sweat secretion
Liver in sympathetic nervous system
Stimulates breakdown of glycogen into glucose
Salivary glands in sympathetic nervous system
Decreases saliva secretion
Tear glands in sympathetic nervous system
Little effect
Adrenal medulla in sympathetic nervous system
Stimulates Adrenalin secretion
Kidney in sympathetic nervous system
Decreases urine secretion
Heart in parasympathetic nervous system
Weakens and slows down heartbeat
Viscera and skin blood vessels in parasympathetic nervous system
Dilate arteries
Lowers blood pressure
Kidney in parasympathetic nervous system
Increases urine secretion
Adrenal medulla in parasympathetic nervous system
No effect
Tear glands in parasympathetic nervous system
Increases tear secretion
Salivary glands in parasympathetic nervous system
Increases saliva secretion
Liver in parasympathetic nervous system
Has little effect on glucose release
Sweat glands in parasympathetic nervous system
Has little effect on secretion
Iris muscles in parasympathetic nervous system
Circular Iris muscles contract which constricts the pupil
Bronchial tube muscles in parasympathetic nervous system
Muscles contract which causes air passages to constrict
Bladder and anal sphincters in parasympathetic nervous system
Causes relaxation
Urinary bladder in parasympathetic nervous system
Contracts bladder wall
Digestive tract in parasympathetic nervous system
Speeds up peristalsis which increases digestion
Heart, lung and skeletal muscle blood vessels in parasympathetic nervous system
Constricts arteries which reduces blood flow
