Roles of the different nervous systems Flashcards
What is the role of the nervous system?
Receive info
Process info
Coordinate a response to info
What are the 2 subdivisions of the nervous system
central ns and peripheral ns
The brain and spinal cord are apart of the
central ns
What is the role of the central ns
enables the brain to communicate with the rest of the body by transferring messages through peripheral ns
The spinal cord receives ________ neurons from the PNS and sends it to the brain
sensory
the spinal cord receives ________ neurons from the brain and sends it to the muscles through the peripheral ns
motor
What is the spinal cord
bundle of nerve tissue that links the brain to the rest of the body
The brain helps
process sensory info
coordinate a response to the info
help maintain the body’s life support
The hindbrain is responsible for
movement and balance
What part of the brain controls the problem solving, high order thinking, and is responsible for processing sensory info
forebrain
What does the midbrain do
coordinates movement and sleep
What is the role of the peripheral ns
transmit info to and from the cns
What are the subdivisions of the peripheral ns
autonomic and somatic ns
The upper part of the spinal cord controls
the communication between the upper parts of the body and the brain
What does the lower part of the spinal cord control
communication between the lower parts of the body and the brain
What is the difference between the sensory neurons and the motor neurons
sensory = transfer the sensations from the receptor sites and travel along sensory neural pathways to the brain via the cns motor = are responsible for communicating with the muscles through messages sent from the brain
sensory info is also known as
afferent neurons
Efferent neurons are also
motor neurons
The autonomic ns is responsible for
self-regulating the body and for the communication between the cns and the body’s organs (heart and stomach etc)
Sympathetic and parasympathetic ns are apart fo the
autonomic ns
What is the sympathetic ns responsible for
becomes active when there is a perceived threat and activates the FFF response
The parasympathetic ns is known for
calming the body after action and maintains the body at a balanced state
What is the frontal lobe?
controls higher order thinking
Primary Motor Cortex = controls voluntary movement of skeletal muscles
What part of the lobe processes sensory info and what is the primary area
parietal lobe
Primary somatosensory cortex = controls incoming sensory info
What does the occipital lobe
controls the visual stimuli
Primary Visual Cortex = processing of visual stimuli
What does the temporal lobe control
processing of auditory info
Primary Auditory Cortex
