Sympathetic and Parasympathetic Nervous Systems Unit 12: Assignment 2 Summary Lesson

Unit 12: Assignment 2 The Nervous System The Endocrine System The inter-relationship between the nervous and endocrine system

Nervous System Central Peripheral Brain/Spinal Cord Cranial/peripheral nerves (reflex actions) Somatic Autonomic Nervous System Nervous System (voluntary actions) (regulatory) Parasympathetic Sympathetic

Sympathetic Nervous System Stressful Situations Danger ‘Fight or Flight’ Neurotransmitters: Acetylcholine (Ach) and Noradrenaline. Heart, breathing, vision, muscle activity increases

Parasympathetic Nervous System Returns systems to ‘normal’ Relaxes after a stressful situation Neurotransmitter: Acetylcholine. Reduces activity in heart, lungs, muscles, digestive system.

Heart Sympathetic: Parasympathetic: Increases heart rate Increases cardiac output Useful in stressful situations to supply blood to muscles for respiration – energy. Parasympathetic: Decreases cardiac output Decreases heart rate Returns heart to normal after stressful situation.

Salivary Gland Sympathetic: Stimulates amylase production Increases digestion Facilitates breakdown of starch into glucose Respiration Parasympathetic: Stimulates watery secretions

Lungs Sympathetic: Relaxes smooth muscles of bronchioles More air can get into lungs More oxygen for respiration Parasympathetic: Contracts smooth muscle of bronchioles Returns system to normal following high stress.

Eye Sympathetic: Ciliary muscles in pupil dilate More light can enter the eye Heightens vision Parasympathetic: Ciliary muscles in pupil constrict Less light can enter the eye
