The postganglionic neuron arise in the _________or cell body ___________the CNS in which the postganglionic fiber is the ______________and are_______________. 2) In the Sympathetic Nervous System the length of the fibers are ___________preganglionic and ________ postganglionic fibers and are located _______to the _________cord. 3) In the Parasympathetic Nervous System the length of the fibers are _________ preganglionic and ____________postganglionic fibers and are located in the ______________ ______________ _________________. 4) In the Autonomic Nervous System the neurotransmitters used are as follows: Parasympathetic _______ganglionic neurons use - _________________ Parasympathetic _________ganglionic neurons use – _________________ In the: Sympathetic _______ganglionic neurons use – _________________ But: Sympathetic _________ganglionic neurons use –__________________. 5) Sympathetic fibers ___________heart and ______________rate, while __________ digestions and ___________ using _________ &___________as the neurotransmitters. While the Parasympathetic fibers _____________heart and ________________rate and _______ digestion and ________________using ___________________as the neurotransmitter. 6) The Visceral Reflexes are the same components as the ______________reflexes but are always ___________________pathways, in which ________________fibers are found in the ____________cord and ______________nerves, and _______________fibers ________ the gastrointestinal _________________activity. 7) Referred pain is pain ____________that arise from the viscera or the _____________ around the ______________and is _________________by the somatic or _________within that region. This takes place due to the visceral pain ________________travel along the same pathways as _____________pain fibers. 8) Sensory receptors that are classed by location are the Exteroceptors which respond to stimuli that arises ________the body or are found near the body__________and are sensitive to______, pressure, ______, and temperature and include special_________ organs, while Interoceptors respond to stimuli arising __________body and are found in internal ________and blood________ which are sensitive to chemical changes and ______________changes as well as__________. 9) Sensory receptor also classed by location are the Proprioceptors which respond to the degree of ___________of organs and are found in __________muscles, tendons, __________, ligaments, and ______________tissue coverings of bones and muscles and are constantly “advising” the brain of one’s____________ and body position. 10) Simple Receptors can be _____________which have free dendritic nerve endings and respond chiefly to _______________and pain such as ____________discs and hair follicle receptors while ________________receptors which are surrounded by tissue. Examples would be____________ and _____________corpuscles . 11) Endoneurium is the nerve covering around ___________fibers. Fascicles are groups of nerve fibers wrapped in _____________and the epineurium is around entire___________.
