Nervous System Fundamentals

What is the master controlling and communicating system of the body?

• The endocrine system

• The nervous system

• The muscular system

• The respiratory system

This is when the nervous system uses its sensory receptors to monitor the changes occurring both inside and outside the body.

• Input

• Integration

• Output

NGSS.MS-LS1-8

This is when the nervous system processes and interprets sensory information and determines what should be done at that moment.

• Input

• Integration

• Output

This is when the nervous system activates effector organs (muscles and glands) to carry out a response.

Which branch of the nervous system contains the brain and spinal cord?

• Peripheral NS

• Sympathetic NS

• Autonomic NS

• Central NS

Which branch of the nervous system consists mainly of nerves that extend from the brain and spinal cord, as well as ganglia?

• Central NS

• Peripheral NS

• Parasympathetic NS

• Autonomic NS

How many neuroglial (or glial) cells are there in the CENTRAL nervous system?

• 2

• 4

• 6

• 8

These types of glial cells are in the CNS. They connect neurons to capillaries and are also used as support. They control the chemical environment around the neuron and help repair if it's injured.

• Oligodendrocytes

• Ependymal

• Astrocytes

• Microglial

These types of glial cells are in the CNS. They have small "thorny" processes for defense and protection of the neuron.

• Astrocytes

• Microglial

• Oligodendrocytes

• Ependymal

These types of glial cells are found in the CNS. They are responsible for forming and circulating cerebrospinal fluid. They have cilia on their surface to help move it through the system.

• Ependymal

• Oligodendrocytes

• Microglial

• Astrocytes
