Psychology Chapter 3 Notes Quiz

Which of the following functions is the human nervous system involved in?

• Thinking

• Breathing only

• Digesting food only

• Producing hormones only

What makes learning and memory possible in humans?

• The digestive system

• The nervous system

• The respiratory system

• The circulatory system

What is the main function of dendrites in a neuron?

• Carry the message away

• Produce energy for the cell

• Receive information from other neurons and pass the message through the cell body

• Insulate and protect the axon

How many axons does a typical neuron have?

• Many

• None

• Only one

• Two

Why is the presence of myelin important for the axon?

• It helps the cell body produce energy

• It allows dendrites to receive messages

• It insulates and protects the axon

• It branches out from the axon

Based on the structure of a neuron, explain why having many dendrites but only one axon is beneficial for neural communication.

• Many dendrites allow the neuron to receive information from multiple sources, while a single axon ensures the message is sent in one clear direction.

• Many axons would confuse the message.

• One dendrite and many axons would speed up communication.

• Having only one of each is more efficient.

What is a synapse?

• A junction between the axon terminals of one neuron and the dendrites of another neuron.

• The main body of a neuron.

• The part of the neuron that receives messages.

• The process of sending messages in both directions.

What do neurons use to send messages across synapses?

• Hormones

• Neurotransmitters

• Enzymes

• Blood cells

Which part of the nervous system transmits sensory images to the central nervous system and is activated by touch, pain, changes in temperature, and changes in body position?

• The Automatic Nervous System

• The Somatic Nervous System

• The Digestive System

• The Endocrine System

What is the main function of the Automatic Nervous System?

• Transmitting sensory images to the brain

• Regulating vital functions such as heartbeat, breathing, digestion, and blood pressure

• Allowing us to feel pain and pressure

• Maintaining posture and balance
