Phase 2. Youâll add foods back to your diet, until you learn how many carbs you can eat while still losing weight. Phase 3. Go to this level when you have about 10 pounds left to lose. Youâll learn how to maintain weight loss and lose the last few pounds.
The term autonomic nervous system (ANS) refers to collections of motor neurons (ganglia) situated in the head, neck, thorax, abdomen, and pelvis, and to the axonal connections of these neurons (Figure 1).rain and spinal cord pathways regulating autonomic outflow. Preganglionic neurons for parasympathetic and sympathetic autonomic outflow are located in the brainstem and in thoracic, upper lumbar and sacral regions of the spinal cord (Figure 1). Several different brain centres control these preganglionic neurons.
C. The axons of the motor neurons of the somatic nervous system extend from the CNS synapse directly to an effector and release acetylcholine, whereas autonomic pathways consist of two sets of motor (efferent) neurons. 1.. The axon of the first (preganglionic) motor neuron of the ANS extends from the CNS and synapses in a ganglion with the second neuron. 2. The second (postganglionic) motor neuron synapses on an effector.
