Convey signals from the central nervous system to muscles
What is the function of dendrites in a neuron?
Receive messages from other cells
Which division of the peripheral nervous system is responsible for involuntary control of glands and smooth muscle?

What type of control does the sympathetic division of the autonomic nervous system exhibit?
Fight or flight
What is the function of the myelin sheath in neural transmission?
Insulates the axon and speeds up the transmission of information
Which type of neuron carries messages from the CNS to muscles for movement?
Motor neurons
What is the role of sensory neurons in neural transmission?

What is the direction of transmission from the dendrites to the axon terminal in neural signaling?
Electrical/neuron
What process involves excess neurotransmitters being re-absorbed by the pre-synaptic neuron?
