What does the Central Nervous System consist of?

• Brain and spinal cord

• Body nerves

• Muscles and glands

• Sensory receptors

Which part of the nervous system controls involuntary bodily functions such as breathing and heartbeat?

• Somatic Nervous System

• Autonomic Nervous System

• Peripheral Nervous System

• Central Nervous System

What is the function of sensory neurons?

• Carry outgoing information from the brain and spinal cord to the muscles and glands

• Detect sensory information

• Carry incoming information from sensory receptors to the brain and spinal cord

• Transmit signals across a synapse from one neuron to another

What is the role of neurotransmitters?

• Protect the neuron and speed up nerve impulses

• Transmit signals across a synapse from one neuron to another

• Detect sensory information

• Control voluntary bodily functions

Which neurotransmitter is involved in regulating hunger and thirst, and the reward pathway and movement?

• Glutamate

• Dopamine

• Serotonin

• GABA

What is synaptic plasticity?

• The process of eliminating unused synapses

• The ability of a synapse to change over time in response to experiences

• The long-lasting weakening of a synaptic connection due to infrequent co-activation

• The growth of additional branches on axons or dendrites to enable new connections

What is the function of the sympathetic nervous system?

• Calms the body, conserving its energy

• Arouses the body, mobilizing its energy in stressful situations

• Controls voluntary bodily functions

• Detects sensory information

What is a reflex response?

• A reaction to a sensory stimulus that involves awareness

• An involuntary reaction to a stimulus

• The process of eliminating unused synapses

• The ability of a neuron to create an alternative synaptic connection with a new neuron

What is an unconscious response?

• A reaction to a sensory stimulus that involves awareness

• A reaction to a sensory stimulus that does not involve awareness

• A reaction to a sensory stimulus that involves thinking

• A reaction to a sensory stimulus that involves decision making

What is the primary role of the parasympathetic nervous system?

• Prepares the body for fight or flight

• Calms the body, conserving its energy

• Controls voluntary movements

• Processes sensory information
