Support Neuroglial Cells
Divisions of the Nervous System
Lobes of the Brain
Nerve Impulses
100

Specialized cells that transmit nerve impulses; consist of a cell body or soma, dendrites, and axon.

What are Neurons?

100

Forms membranes around nerve tissue

What is Ependymal cells?

100
Nervous system division that uses cranial nerves and spinal neurons. Includes the brain and spinal cord. Integrates information 
What is the Central Nervous System?
100

Which lobe of the brain is responsible for body movement of the right side of the body?

What is the left hemisphere motor cortex?

100
At the beginning of a nerve impulse the membrane is at what state?

What is resting potential?

200

Branch-like structures that receive signals from other neurons

What are dendrites?

200

Immune functions, digest debris, kill bad bacteria

What are Microglial Cells?

200

Decreases heart rate and promotes digestion (rest and digest response).

What is activation of the parasympathetic nervous system?

200

What lobe of the brain is responsible for the left eye?

What is the right hemisphere occipital lobe?

200
A wave of action potentials traveling the length of an axon is called what

What is nerve impulse?

300

Insulating layer around the axon made by Schwann cells.

What is Myelin Sheath?

300

Makes myelin sheath that provides insulation to the axon. Attached to dendrite and soma to cover axon (in central nervous system)

What are Oligodendrocytes?

300

Components of the autonomic nervous system

What are Sympathetic and Parasympathetic?

300

What lobe and hemisphere is known for being the creative side?

What is the right frontal lobe?

300
When sodium diffuses inward what happens to the charges inside and outside the neruron?

- outside --> + inside 

400

Part of neuron that transmits signals away from the soma to other neurons or muscles.

What is Axon?

400

Connects blood vessels to neurons

What are Astrocytes?

400

Motor neurons, sends signals from the brain to skeletal muscles, voluntary 

What is somatic nervous system?

400

What is responsible for balance and muscle memory?

What is the cerebellum?

400

What are the 2 things that can open and close during a nerve impulse?

What are voltage gated sodium channels and potassium channels?

500

Gaps in the myelin sheath that the signals up to.

What is Nodes of Ranvier?

500

Makes myelin sheath that surround neurons in the peripheral nervous system 

What is Schwann cells?

500

Efferent = exits the brain, sends messages from brain to the muscles and glands, motor neurons for motor output

What is the motor division?

500

What part of the brain stem is responsible for heartbeat, breathing, and blood pressure

What is the medulla oblongata?

500

Major ions (elements) involved in resting potential

What are Sodium (Na+) and Potassium (K+)
