Step by step
Solved in 3 steps
- Once a sympathetic preganglionic axon reaches a paravertebral ganglion, it can: pass through the paravertebral ganglion without synapsing until it reaches the prevertebral ganglion. O True FalseThe cell bodies of sympathetic preganglionic rHeurons are located in O the dorsal root ganglia the ventral horn small neuronal clusters situated outside of target organs such as the intestines and kidne the intermediolateral cell column of the spinal cordOnce a sympathetic preganglionic axon reaches a paravertebral ganglion, it can: synapse with a post- ganglionic neuron, at the same spinal segment level. O True False
- Circulating glucocorticoids (e.g. cortisol) can inhibit the activity of the HPA axis via the negative feedback loop working on the Hippocampus Amygdala Limbic cortex Thalamus O All of the aboveFor which of the following systems is the neurotransmitter acetylcholine released by neurons at the target tissue? true only for the sympathetic division true only for the parasympathetic division true for both divisions false for both divisionsCharacteristics o Sympathetic Parasympathetic Main function Location of nerve roots Effects on target Organs &physiological processes Heart Bronchioles(airway passages of the lungs) Blood vessels to abdominal organs & skin Blood vessels to skeletal muscle secretion from digestive glands Urine formation/Micturition (urination) pupils of the eye
- Which of the following describes a sympathetic postganglionicaxon?a. long, unmyelinated axonb. short, myelinated axonc. short, unmyelinated axond. long, myelinated axonFigure 35.26 Which of the following statements is false? The parasympathetic pathway is responsible for relaxing the body, while the sympathetic pathway is responsible for preparing for an emergency. Most preganglionic neurons in the sympathetic pathway originate in the spinal cord. Slowing of the heartbeat is a parasympathetic response. Parasympathetic neurons are responsible for releasing norepinephrine on the target organ, while sympathetic neurons are responsible for releasing acetylcholine.In the sympathetic division of the autonomic system: preganglionic neurons originate in the thoracolumbar segments of the cord the preganglionic neurons are unmyelinated the preganglionic neurons are long the neurotransmitter released by the preganglionic neurons is norepinephrine
- Once a sympathetic preganglionic axon reaches a paravertebral ganglion, it can: ascend or descend the sympathetic trunk, to synapse in another paravertebral ganglion. True O FalseBoth sympathetic and parasympathetic preganglionic neurons are cholinergic and secrete the neurotransmitter- O acetylcholine O norepinephrineThe Parasympathetic nerves have : select all Long myelinated pre-ganglionic nerve Short none myelinated post ganglionic nerve Ganglion closed to the organ Ganglion close to the spinal cord
