Autonomic: control smooth muscle, cardiac muscle, glands and some adipose tissue, involuntary (not always correct, works with endocrine and behavioural state system to maintain homeostasis. Both divisions of the autonomic nervous system innervate most e ector organs. Primary function: regulate organs to maintain homeostasis. Parasympathetic and sympathetic activities tend to be antagonistic: parasympathetic nervous system: rest, sympathetic nervous system: ght or ight response, picture. Autonomic ns works closely with endocrine system to maintain homeostasis. Sensory information goes to homeostatic control centres: hypothalamus, pons, medulla. Wednesday, january 30, 2019: blood pressure, temperature control, water balance. Motor output creates responses: autonomic, endocrine, behavioural. Can also create emotions in uencing autonomic functions: fainting when see a needle, blushing. Some autonomic re exes do not int from the brain: spinal re exes. Autonomic branches: one is excitatory, other is inhibitory.
