Divisions of the Nervous System Flashcards
Brain and spinal cord.
Central Nervous System
Nerves and ganglia outside the
CNS.
Peripheral Nervous System
Composed of the brain and spinal cord,
responsible for data processing and
command initiation
Central Nervous System
Includes all nerves outside the CNS, connecting it
to the body for sensory and motor functions
Peripheral Nervous System
Conducts impulses from sensory receptors to
the CNS, monitoring external and internal
conditions
Sensory (Afferent)
Transmits signals from the CNS to muscles and
glands, managing voluntary and involuntary
responses
Motor (Efferent)
Regulates involuntary actions through sympathetic
(“fight or flight”) and parasympathetic (“rest and
digest”) responses
Autonomic Nervous System
Specialized network in the digestive tract that can
function autonomously, though it also integrates
with the CNS
Enteric Nervous System
