Reticular substance of brain stem
Which level of CNS functions is responsible for walking movements and withdrawal from painful objects?
Spinal cord level
What is the role of synapses in information processing in the CNS?
Blocking weak signals and allowing strong signals to pass
Which part of the nervous system has a complex synaptic arrangement called a glomerulus?
Subcortical circuits
What type of transmitters cause most acute responses of the nervous system?
Small-molecule, rapidly acting transmitters
What is the function of neuropeptides in the nervous system?
Prolonged actions such as changes in the number and size of synapses
Where are neuropeptides synthesized in the nervous system?
In the neuronal cell body
Which part of the CNS is responsible for thought processes and conscious awareness?
Higher brain or cortical level
What is the role of synaptic transmission at chemical synapses?
Involves several steps, including action of the transmitter substance on the postsynaptic neuron
Where does transmission of sensory information to the brain occur in the nervous system?
Both peripheral nerves and reflex arcs
