Exploring the Human Nervous System

What are the main parts of a neuron?

• Cell body, dendrites, axon

• Glial cells, axon terminals, myelin sheath

• Nucleus, ribosome, mitochondria

• Cell membrane, synapse, neurotransmitter

What is the function of the axon in a neuron?

• The axon receives signals from other neurons.

• The axon transmits electrical impulses away from the neuron's cell body.

• The axon protects the neuron from damage.

• The axon stores neurotransmitters for later use.

Describe the role of the central nervous system

• The central nervous system only controls voluntary movements.

• The central nervous system processes information and coordinates actions in the body.

• The central nervous system solely regulates body temperature.

• The central nervous system is responsible for digestion and metabolism.

What two main parts make up the central nervous system?

• Liver and kidneys

• Heart and lungs

• Stomach and intestines

• Brain and spinal cord

What is the peripheral nervous system responsible for?

• The peripheral nervous system is responsible for connecting the central nervous system to the rest of the body and facilitating communication.

• Regulating heart rate and blood pressure

• Processing sensory information from the environment

• Controlling voluntary muscle movements

Name one type of neuron and its function.

• Sensory neuron

• Motor neuron

• Glial cell

• Interneuron

How do sensory neurons differ from motor neurons?

• Sensory neurons carry information to the CNS; motor neurons carry information away from the CNS.

• Both sensory and motor neurons carry information to the CNS.

• Motor neurons are responsible for processing sensory information.

• Sensory neurons transmit signals from muscles to the brain.

What is the protective covering of the brain called?

• Neurons

• Meninges

• Skull

• Cerebrospinal fluid

What is the role of neurotransmitters in the nervous system?

• Neurotransmitters act as hormones in the bloodstream.

• Neurotransmitters facilitate communication between neurons in the nervous system.

• Neurotransmitters are responsible for muscle contraction.

• Neurotransmitters store genetic information in neurons.

How does the spinal cord contribute to the nervous system?

• The spinal cord acts as a storage center for memories.

• The spinal cord is responsible for producing hormones.

• The spinal cord transmits signals between the brain and body, processes reflexes, and coordinates motor functions.

• The spinal cord only supports the body structurally.
