dendrite
What is the branch part of the neuron that receives messages and sends them to the cell body?
axon
What is the branch part of the neuron that transports messages away from the cell body?
neuron

reflex
When a movement causes the spinal cord to interpret an impulse from the brain from sensory receptors this movement is called a ________.
spinal cord
Which part of the body is made up of bundles of neurons that carry impulses from all parts of the body to the brain and from the brain to all parts of the body?
homeostasis
The regulation of steady, life-maintaining conditions inside an organisms is called ________.
stimuli
The senses act as the body's alert system, reacting to ________ and transmitting impulses to the brain.
