The Nervous System Flashcards
CNS
Central Nervous System; Processes and responds to information from the PNS.
what is the CNS divided up into
Brain and Spinal Chord
role of the brain in the CNS
master organ, decides what to do with any information
what 3 sections can the brain be split into
forebrain, midbrain, hindbrain
what is the spinal chord
nerve tissue that extends from the base of the brain to the lower back.
role of spinal chord
takes sensory information from PNS to the brain
takes motor information from brain to the PNS
what does S.A.M.E stand for
Sensory Afferent Motor Efferent
What does S.A.M.E mean
Sensory neurons take the Afferent track to the brain
Motor neurons take the Efferent track from the brain
what does PNS mean
Peripheral Nervous System
what can the PNS be divided into
Somatic Nervous System and Autonomic Nervous System
role of PNS
network of nerves, transmits information from muscles glands and sense organs to the CNS.
It also transfers messages from the CNS to the body
what can the somatic nervous system be split into
Sensory neurons and motor neurons
what can the autonomic nervous system be split into
sympathetic and parasympathetic
role of somatic nervous system
responsible for voluntary/concious actions such as picking up a pen or walking somewhere. it carries messages from sense organs.
sensory neurons are important for
sensations
