The main function autonomic nervous system
maintain homeostatis
Autonomic nervous system is also known as
subconscious or involuntary nervous system
How many neurons are in the somatic efferent pathways
1
How many neurons are in the autonomic pathways
2
The somatic nervous system conducts impulses from where to where
the motor cortex to the c.n.s to the skeletal muscles
The autonomic conducts motor impulses from which part of the brain to where
Hypothalamus to cardiac muscles, smooth muscles and glands
Even though the autonomic system is involuntary can we influence our conscious state
Yes. If we are anxious prior to an exam (can increase heart rate by emotions or thoughts)
In the somatic efferent pathway where does the cell body reside and where does the axon extend to
cell body resides in cns
axon extends to effector organ. it usually follow spinal or cranial nerves.
Always goes to Skeletal muscles.
Does the somatic efferent pathway synapse
no
What are the two neurons in the autonomic pathways called
preganglionic neurons& postganglionic neurons
Where does the preganglionic cell body reside and what does its axon then do
cell body resides in cns
the axon then synapses with the post ganglionic neuron.
Does the somatic pathway have ganglia
no
What is the main difference between the somatic and autonomic pathways
the number of neurons.
Where does the post ganglionic cell body reside and what does the axon do
Cell body resides outside the cns and the axon extends to the effector organ (cardiac, smooth muscle or gland)
What is the neurotransmitter in the somatic pathway called
ACh. Acetylcholine
This neurotransmitter Ach what does it do in the somatic nervous system
it always excitable,
it stimulates
causes muscle contractions
Does this acetylcholine inhibit the somatic nervous system
no , never inhibits only excites.
What is the preganglionic neurotransmitter
