somatic/ vs autonomic nervous system Flashcards
Is somatic motor nervous system involuntary or voluntary
voluntary
What is somatic nervous system innervating
innervation of skeletal muscle and leads to voluntary muscle contraction
Is there one or 2 efferent nurons
1 efferent neuron that directly innervates target cells
What is the nuerotransmitter realeased in skeletal muscle
Acetoylcholine
Is autonomic concious or unconcious
unconcoius
What does the autonomic nervous system innervate
innervation of smooth muscle.
is there 1 or 2 efferent neurosn in the autonomic system
2- pregangliotic and post gangliotic
How many neurotransmitters can there be fore autonomic nervous system
the neurotransmitter depends on postgangliotic neuron
What are the two divisions of the autonomic nervous system
Sympathetic and Prasympathetic
Where are the pre gangliotic cells located in sympathetic nervous system and where is the ganglion located
Thoracic and lumbar regions of spinal cord. Ganglion location is close to spinal cord
Where is the pre gangliotic cell bodies located in the parasympathetic divisiona and where is the ganglion division
Pre gangliotic cells located in the brainstem.
Ganglion location is on or close to target organ and
What does the pregangliotic cell realease to postgangliotic neuron (sympathetic division)
Releases acetylcholine onto post gangliotic neuron.
What does the post gangliotic nwuron release to target cells? (sympathetic)
Releases norepinepherine or epinepherine onto target cells.
What does the pregangliotic cell realease to postgangliotic neuron (parasympathetic division)
Releases acetylcholine on postgangliotic neuron
What does the post gangliotic nwuron release to target cells? (parasympathetic)
releases ach onto target cells
