Control and Communication Flashcards
What does the nervous system consist of
the central nervous system and other nerves ( peripheral nervous system )
what does the central nervous system consist of
the brain and the spinal cord
how does the CNS control the body
by receiving information from sense organs and then responding to that information
how is information from the CNS carrier
by nerve cells called neurons
what is the function of the cerebrum
controls memory, reasoning, imagination, conscious thought and intelligence
function of the cerebellum
controls balance and muscular coordination
function for the medulla
controls breathing and heart rate
what is a response to stimuli
can be a rapid action from a muscle or a slower response from a gland
what are the three types of neurons
sensory neurons
inter neurons
motor neurons
what is the function of sensory neurons
to pass the information to the cns
what is the inter neurons function
to operate within the CNS which processes information from the senses that require a response
what is the function of motor neurons
enables a response to occur at an effector
what ways is information carried in the CNS
electrical impulses
chemical messengers
what do electrical impulses do
carries messages along the neurons
what does chemical messengers do
transfer the messages between neurons at synapses
