What is the primary function of the parietal lobe?

Back

The parietal lobe primarily focuses on receiving and processing sensory information from the sensory organs.

Front

What are the two main divisions of the nervous system?

Back

The two main divisions of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).

Front

What are Nodes of Ranvier?

Back

Nodes of Ranvier are small gaps in the myelin sheath of a neuron that facilitate the rapid conduction of nerve impulses.

Front

Which part of the brain is responsible for coordination and balance?

Back

The cerebellum is responsible for coordination, balance, and fine motor control.

Front

What does the sacral plexus innervate?

The sacral plexus communicates with the posterior leg and parts of the pelvis.

Front

What is the role of the frontal lobe?

Back

Front

What is the function of the occipital lobe?

Back

The occipital lobe is primarily responsible for processing visual information.

Front

What is the difference between the CNS and PNS?

Back

The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that branch out from the CNS to the rest of the body.

Front

What is myelin and its function in the nervous system?

Back

Myelin is a fatty substance that insulates nerve fibers, increasing the speed of electrical impulses along the neuron.

Front

What is the function of sensory neurons?

Back

Sensory neurons transmit sensory information from the sensory receptors to the CNS.
