Nervous System: Match the following definitions with the appropriate terms. The part of a neuron that receives signals is called the ______. When a neuron releases neurotransmitters, it can then "clean them up" by taking them back, which is called ______. Another way that neurons can "clean up" neurotransmitters after they're released is by breaking them down, which is called ______. Large molecules that can help break down neurotransmitters are called ______. The part of the neuron that sends signals is called the ______. a. enzymes b. metabolization c. axon d. dendrite e. reuptake

'Match the concept with the correct section of the nervous system: Central nervous system Consists of the brain and spinal cord Responsible for sending sensory messages to the CNS and sending motor messages to muscles and glands Autonomic nervous system Parasympathetic nervous system 3. Responsible for voluntary control: sense receptors send messages to the CNS and impulses travel from the CNS to effectors (muscles) Peripheral nervous system Sympathetic nervous system Responsible for involuntary control: controls glandular secretions (enzymes and hormones) and the function of smooth and cardiac muscles Somatic nervous system 5. Activated in emergencies and in times of stress 6. Activated when the body is calm, at rest and digesting a meal'
