ANS Flashcards
The nervous system is divided into two systems:
Somatic nervous system
Autonomic nervous system
Both the somatic and the autonomic nervous system include ___ and ____ components
Central nervous system
Peripheral nervous system
In both the ANS and the somatic systems the _____ consists of one neuron coursing from the receptor to the CNS
sensory (afferent)
In the somatic system, the ______ pathway consists of one neuron coursing from the CNS to the effector
Motor (efferent)
In the ANS, the motor pathway from the CNS involves two neurons:
Pre and post ganglionic neuron
Defined as a collection of neuron cell bodies outside the CNS
ganglion
Name of a neuron that has its cell body in the CNS and courses to the autonomic ganglion is
pre-ganglionic neuron
Neurons hat has it’s cell body in the autonomic ganglion and carries the impulse from that ganglion to the effector
post ganglionic neuron
Somatic effectors are ____ muscles
skeletal
Somatic skeletal muscles are _____ and under conscious control
voluntary
The ANS effectors of the body are _____ muscle, ___ muscle and ___
smooth; cardiac; glands (exocrine and endocrine)
The ANS effectors of the body are ___ and function without any conscious control
involuntary
The motor (efferent) component of the ANS is divided into 2 separate systems
Sympathetic
Parasympathetic
“Fight or flight”
sympathetic nervous system
Sympathetic nervous system involves spinal segments:
T1-L2
