Exploring the Nervous System

What is the nervous system responsible for?

• The nervous system is responsible for coordinating bodily functions and processing sensory information.

• Producing hormones and enzymes

• Regulating body temperature and digestion

• Transporting oxygen and nutrients

Define the term 'neuron'.

• A neuron is a specialized cell that transmits information in the nervous system.

• A neuron is a type of muscle cell.

• A neuron is a type of blood cell.

• A neuron is a hormone that regulates mood.

What are the main parts of a neuron?

• Axon, soma, action potential

• Soma, synapse, neurotransmitter

• Cell body, dendrites, axon

• Dendrites, myelin, glial cells

What is the function of the central nervous system?

• To filter toxins from the blood.

• To produce hormones that regulate metabolism.

• The function of the central nervous system is to process information and coordinate bodily functions.

• To store memories and experiences.

Name the two main divisions of the nervous system.

• Sympathetic Nervous System and Parasympathetic Nervous System

• Central Nervous System and Peripheral Nervous System

• Autonomic Nervous System and Somatic Nervous System

• Cerebral Nervous System and Spinal Nervous System

What role does the peripheral nervous system play?

• The peripheral nervous system controls only voluntary muscle movements.

• The peripheral nervous system is responsible for hormone production.

• The peripheral nervous system only processes sensory information.

• The peripheral nervous system connects the central nervous system to the rest of the body, enabling communication and coordination.

What is a neurotransmitter?

• A neurotransmitter is a type of electrical signal sent by the heart.

• A neurotransmitter is a protein that builds cell membranes.

• A neurotransmitter is a chemical messenger that transmits signals between neurons.

• A neurotransmitter is a type of hormone that regulates mood.

What is a synapse?

• A synapse is a type of neurotransmitter.

• A synapse is a hormone that regulates mood.

• A synapse is a muscle fiber that contracts.

• A synapse is the connection point between two neurons that facilitates communication.

Describe the process of nerve impulse transmission.

• Nerve impulse transmission occurs only in the brain.

• Nerve impulses are transmitted through chemical signals only.

• Nerve impulses travel at the speed of light.

• Nerve impulse transmission is the process by which electrical signals are propagated along neurons and communicated to other neurons or muscles.

How do sensory neurons differ from motor neurons?

• Sensory neurons transmit signals from muscles to the brain.

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

• Sensory neurons only function in the peripheral nervous system.

• Motor neurons are responsible for processing sensory information.
