These are places on the membrane to which neurotransmitters bind.

Produce myelin sheath for neurons in the CNS

Formed with blood, clear, composed of water, glucose, protein, and several ions

What does the diencephalon include?

relays sensory and motor information, contains nuclei that are reflex areas (vision & hearing)

This is made of glial cells that act as a barrier to the brain.

(T or F) Myelination does not increase speed of the signal.

A deep sulcus is called a

As the inside of the cell changes from negative to positive, it it said to?

This area uses a large storage of knowledge and experience to give words meanings

This sleep is known by changing BP, Respiratory rate, HR, and rapid eye movements. 90-120 min.

This connects the spinal cord with higher brain structures.

This is a broad area concerned with translation of thoughts into words.

The meninges can become inflamed or infected causing

Throughout the white matter there are patches of gray matter called?

The space between axon terminal and the dendrite

What cation leaks out of the Neuron during polarization(resting state)

This lobe receives info from the skin, muscles & participates in speech, taste & reading

Integrating system for ANS regulates temp. water balance, sex, thirst, appetite, some emotions

Part of the diencephalon and cerebrum form a wishbone-shaped area, called the "emotional brain"

This refers to the electrical charge difference across the membrane of the resting neuron

Is the inner layer of the meninges means soft, or gentle mother

During depolarization what cation is allowed to rush in changing the charge of Neuron

This disease is sometimes called "shaking palsy"

These areas are concerned primarily with analyzing, interpreting, and integrating information?

When the neuron stops accepting Na+ and allows K+ to diffuse out of the cell what is happening?

What are the divisions of the nervous system?

Damage to the _____ is associated with a state of deep coma which can be permanent

An axon terminal contains thousands of tiny vesicles that store

Each nerve impulse works like a _______ . Depolarizing adjacent membranes.

Which lobe contains the olfactory area, and the primary auditory cortex?

These are substances that terminate the activity of the neurotransmitters.

What does proprioception mean?

"nerve glue" the most abundant of the nerve cells, support, protect, insulate, and nourish,

The large fiber tract allowing the cerebral hemispheres to communicate is the?

This separates the precentral and postcentral gyrus

Acts as a 'relay station" for most of the lower brain and spinal cord.

Clusters of cells within the PNS

Extending through entire brain stem, & cerebral cortex concerned with the sleep wake cycle.

The cell returns to its negative shape or resting state

What kind of matter is made up of unmyelinated axons, cell bodies, interneurons, and synapses

This formation keeps us awake and focused, helps us ignore background formation.

A deficiency of dopamine within the basal nuclei called

What is a nerve impulse called?

The bulk of the cerebrum is composed of _____ located directly below the cortex

These protrude up into the blood-filled dural sinuses and are involved in the drainage of CSF

In a myelinated fiber, the nerve impulse jumps from what to what? what is this "jumping"

A thin layer of gray matter in the cerebrum called the

This part of the brain "times" events allowing the person to track moving objects

What is neurilemma important in doing?

Produce myelin sheath for neurons in the PNS assist in neurilemma

Found only in CNS; connect sensory and motor nerves

This function uses temporal, parietal and occipital lobes, and normally of the left side.

Where is CSF formed

Lasts much longer- years, decades, or a life time

This part of the brain is also known as the primary somatosensory area.

Gyri are separated by grooves called

These carry information from CNS toward periphery

The middle layer looks like a spider web.

Scattered throughout the white matter are patches of gray matter called?

These help regulate body movement and facial expression

Which of these is protecting the Central Nervous System

This is the largest part of the brain, four lobes, two hemispheres

These are important in transmission of electrical signal, nonmitotic

In the frontal lobe this controls voluntary eye movements and the eyelids

This is a hyporesponsive state with several stages ranging from light to deep.

This is a brain structure responsible for the perception of taste.

Your ability to remember the first words of a sentence so you can finish the sentence.

The outermost layer is thick, tough, connective tissue called

This receives information from the ear?

What is a function of the nervous system?

This is the hearing, smelling, taste, memory storage, & part of speech area

Located at the base of the skull, Mediates reflexes, Coordinates motor activity & sensory input

(T or F) Drainage of CSF must equal its production

In the frontal lobe this directs the muscles of the larynx, tongue, cheeks, and lips to speak

Which of these is not part of the neuron

What does (LOC) mean?

Where is it in the Nervous system that neurotransmitters are stored?

Clusters of cell bodies within the CNS are called

Star shaped cells, present in blood brain barrier, bind blood vessels, acts as phagocytes.

What is this in the picture?

(T or F) Sleep occurs when RAS is inhibited or slowed

Protective role; phagocytosis of pathogens and damaged tissue

Why is white matter white?

The medulla oblongata contains the emetic center also called the?
