Lesson 2 Interim Review

Front

What part of the nervous system processes and interprets information?

Back

Central nervous system (CNS) is responsible for processing and interpreting information.

Front

What is the primary role of the myelin sheath?

Back

The myelin sheath speeds up electrical signals along the axon.

Front

What do sensory neurons do?

Back

Sensory neurons transmit information from sensory receptors to the central nervous system (CNS).

Front

What do motor neurons control?

Back

Motor neurons control muscle movement and response.

Front

What is the purpose of a CT scan ordered by a neurologist?

Back

A CT scan is used to visualize brain structures for abnormalities.

Front

Define the central nervous system (CNS).

Back

The central nervous system (CNS) consists of the brain and spinal cord, and it processes information.

Front

What is the function of sensory receptors?

Back

Sensory receptors detect stimuli from the environment and send signals to sensory neurons.

Front

Explain the role of neurotransmitters in the nervous system.

Back

Neurotransmitters are chemicals that transmit signals across synapses between neurons.

Front

What is the function of the peripheral nervous system (PNS)?

Back

The peripheral nervous system (PNS) connects the CNS to the rest of the body, including limbs and organs.

Front

What is the role of the axon in a neuron?

Back

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