Autonomic Nervous System Sympathetic NS Parasympathetic NS “Fight or Flight” “Rest and Digest” Stress

Autonomic Nervous System Sympathetic NS Parasympathetic NS

Sympathetic Nervous System ? Heart Rate? Blood Pressure? Breathing? Digestion? Pupil Size? Sweat? Blood to skeletal muscles?

Parasympathetic Nervous System ? Heart Rate? Blood Pressure? Breathing? Digestion? Pupil Size? Sweat? Blood to skeletal muscles?

Parasympathetic Nervous System Otto Loewi (Dream 1  Dream 2) ? To lab!

Autonomic Nervous System Conscious Control of ANS? 1.Resting Heart Rate = ?? 2.Exercise Heart Rate = ?? 3.Resting Heart Rate = ?? 4.Relaxation/Other Heart Rate = ?? Control of other autonomic functions such as body temperature, breathing, digestive function.
