Nervous System Review

Front

What is white matter composed of?

Back

White matter is primarily composed of myelinated axons, which are responsible for transmitting signals between different parts of the nervous system.

Front

Where is the primary auditory cortex located?

Back

The primary auditory cortex is located in the temporal lobe of the brain.

Front

What part of the neuron is observed at a Node of Ranvier?

Back

At a Node of Ranvier, you are observing the axon of the neuron.

Front

What is the function of acetylcholinesterase?

Back

Acetylcholinesterase destroys the neurotransmitter acetylcholine shortly after its release by axon endings, thus terminating the signal.

Front

What structure in the brain controls conscious thought and memory?

Back

The cerebrum controls conscious thought and memory.

Front

What is the role of myelin in the nervous system?

Back

Myelin insulates axons, increasing the speed of electrical signal transmission along the nerve fibers.

Front

What are neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across a synapse from one neuron to another.

Front

What is the function of the cerebellum?

Back

The cerebellum is responsible for coordinating voluntary movements, balance, and motor learning.

Front

What is the difference between the central nervous system and the peripheral nervous system?

Back

The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes all the nerves outside the CNS.

Front

What is the function of sensory neurons?

Back

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