Ch 30 ANS Flashcards
Both the somatic nervous system and autonomic nervous system include the _ and _ nervous system components.
central and peripheral
The nervous system is divided into 2 functional systems:
somatic nervous system
autonomic nervous system
In both the ANS and somatic nervous system the sensory pathway consists of 1 neuron coursing from the _ to the _.
receptor
CNS
In the ANS the motor pathway away from the CNS involves _ neurons.
two
A _ is a collection of neuron cell bodies outside the CNS
ganglion
The _ neuron has its cell body in the CNS and courses to the autonomic ganglion
pre-ganglionic neuron
The _ neuron has its cell body in the autonomic ganglion and carries the impulse from that ganglion to the effector.
post-ganglionic neuron
The _ effectors are skeletal and they are voluntary with conscious control.
somatic
The ANS effectors of the body are _ muscle, _ muscle, and _ (exocrine/endocrine). They are involuntary and function without conscious control.
smooth muscle
cardiac muscle
glands
The motor (efferent) system in the ANS is divided into 2 separate systems:
Sympathetic
Parasympathetic
The sympathetic nervous system has short preganglionic and long postganglionic fibers and involves spinal segments:
T1-L2
The SNS has ganglia found near the _ _
spinal cord
The SNS exhibits _ _ where stimulation activates multiple organs at once
unit action
The PNS has long preganglionic and short postganglionic fibers and involves these nerves:
CN III, VII, IX, X
Spinal segments S2-4
The PNS’ ganglia are found near or within the _ _
target organ
