MGMT 2103 UARK Exam 3 Manno A&P.Final Exam Test 2024\2025.
functional organization
this organization of the nervous system is based on what type of information is carried and its direction
sensory nervous system
also known as the afferent nervous system
afferent
toward CNS
somatic sensory and visceral sensory
two branches of sensory nervous system
somatic sensory
detect stimuli we consciously perceive
visceral sensory
detect stimuli we do not consciously perceive
motor nervous system
also known as the efferent nervous system
efferent
away from CNS
somatic motor and autonomic motor
two branches of motor nervous system
somatic motor
"voluntary" nervous system
autonomic motor
"involuntary" nervous system
sympathetic and parasympathetic
two divisions of the autonomic nervous system
dendrites
short, small tapering processes that branch off the soma
graded potentials
dendrites transmit which potentials toward the soma?
soma
defined by presence of nucleus
graded potentials
soma transmits which potentials toward axon hillock?
axon
single, longer process extending away from soma
, MGMT 2103 UARK Exam 3 Manno A&P.Final Exam Test 2024\2025.
action potentials
axon transmits which potentials?
axon hillock
junction between soma and axon where action potentials are initiated
synaptic knobs
small bulb-like endings at tips of axon branches that transmit signals to other neurons, muscles, glands
structural classification
which classification of neurons is based on number of neuronal processes emanating from soma?
anaxonic
only dendrites, no axon
unipolar
single, short process emerges from soma and branches like a "t"
bipolar
two process extend from soma: one dendrite and one axon
multipolar
many dendrites and a single axon
functional classification
which classification of neurons is based on direction action potential travels relative to CNS?
sensory neuron
neurons that carry incoming information from the sensory receptors to the brain and spinal cord
interneuron
central nervous system neurons that internally communicate and intervene between the sensory inputs
and motor outputs
motor neuron
a neuron that sends an impulse to a muscle or gland, causing the muscle or gland to react
presynaptic and postsynaptic neurons
two neurons that are in both chemical and electrical synapses
chemical synapse
nerve impulse transmitted with assistance of a chemical neurotransmitter across a synaptic cleft
synaptic cleft
narrow gap between two neurons
neurotransmitters
are released from synaptic vesicles and bind to postsynaptic receptor
chemical synapse
there's a delay (~0.3-0.5 ms) in the transmission of information with this synapse
