Central Nervous System (CNS)

Meninges

The brain and spinal cord are protected by membranes known as:

Glial cells

The brain's supporting cells are called:

Cerebral cortex

The large, highly convoluted outer surface of the brain is called the:

Occipital lobe

The centers of vision are located in the _______________lobe of the cerebral cortex.

Frontal, parietal, temporal and occipital

Name the 4 lobes of the cerebral cortex:

Broca's area; motor aphasia

Jane has a brain injury. She can speak but her speech is slurred. The part of her brain that is injured is (Broca's area or Wernicke's area). Slurring of speech is called ______________:

Gyri; sulci

The elevated ridges of tissue on the surface of the cerebral hemispheres are called _________________ while the shallow grooves are called __________________.

The brain and spinal cord

The term central nervous system refers to the:

Ventricles

Cavities of the brain are called:

Dura mater

The outermost membrane surrounding the spinal cord:

Astrocytes

Glial cells that help form the blood-brain barrier:

B) Muscle coordination

The main function of the cerebellum is: A) Consciousness B) Muscle coordination C) Homeostasis D) Sense reception

Bathe and support neural tissue and maintain electrolyte balance around neurons.

What is the function of cerebrospinal fluid (CSF)?

Size; density

The ability to locate a stimulus depends on the ______________ and ______________ of the receptive fields.

Paradoxical; beta

REM sleep is also called ________________. The EEG resembles an alert awake brain with _______________ rhythm.

Ependymal cells

Type of glial cell that physically support neurons and form the cerebrospinal fluid.

Dorsal; sensory

The ascending tracts form the ____________ columns and carry _____________ information to the brain.

Dermatome

The area of skin supplied by a pair of spinal nerves:

Muscle force; muscle length

Golgi tendon organs signal ________________ while muscle spindles respond to changes in ________________.

Perception

A sensation combined with an understanding of its meaning ________________.

False. CST neurons are only one synapse away from muscle and are called the final common path.

True or false: Corticospinal tract neurons are two CNS synapses away from muscle.

Vermis, intermediate zone, lateral zone, flucculonodular lobe

Name the 4 functional zones of the cerebellum:

Stimulates the sleep center and inhibits orexin producing neurons.

What is the role of adenosine in the sleep/wake cycle?

Sensorimotor cortex

This includes all parts of the cerebral cortex that act together to control muscle movement.

Wakefulness

Orexin promotes ___________________(wakefulness/sleep)

Primary motivated behavior: directly related to homeostasis. Secondary motivated behaviour: behavior that results in pleasure.

What is the difference between a primary motivated behavior and secondary motivated behavior?
