Autonomic Nervous System Flashcards
1
Q
Autonomic Nervous System
A
Controls vital functions such as heart rate, blood pressure, digestive and urinary processes
The sympathetic and parasympathetic divisions of the nervous system work together to maintain homeostasis

A
1. sensory signals from the organs and skin are sent by sensory neurons to the brain.
2. stimuli are integrated at the CNS
3. motor impulses from the neurons are sent out to the autonomic ganglia
4. target tissues receive a motor response
