Activity B:Learning the Autonomic Nervous System
Fill in the blanks below.
The Autonomic Nerovus System is a ___________________ (voluntary, involuntary) system. Its two divisions are the _________________ and _______________. The system's effectors are the _____________________, ____________________ and _______________________. In these system there are _____________ (one, two) motor neurons between the CNS and the effectors. The first motor neuron is also called the ________________ (preganglionic, postganglionic) fiber. This fiber is always _________________ (myelinated, unmyelinated) and always releases the neurotrnasmitter_______________ (norepinephrine, acetylcholine). When both divisions of the Autonomic Nervous System act on an organ it is called ______________ (duel, singular) innervation. Parasympathetic preganglioinc cell bodies are located in two areas. One is in the brain and its fibers travels out in cranial nerves _______________, _______________, ________________ and _______________. A second location is the _____________ (anterior, lateral) gray horn of segments ____________ through __________ of the spinal cord. The Sympathetic preganglionic cell bodies are found in the _____________ (anterior, lateral) gray horns of segments ___________ through _______________ of the spinal cord.
