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.
Motor neurons' axons are efferent nerve fibers that carry signals from the spinal cord to the effectors to produce effects. Types of motor neurons are alpha motor neurons, beta motor neurons, and gamma motor neurons.There are upper motor neurons and lower motor neurons, with the cell type described above being a lower motor neuron.Upper motor neurons are cortico-spinal interneurons that arise from the motor cortex and descend to the spinal cord where they activate the lower motor neurons through synapses.ypes of motor neurons are alpha motor neurons, beta motor neurons, and gamma motor neurons.
