The Central Nervous System

What does the Medulla Oblengata do?

• all involuntary actions such as breathing and regulation of heart rate

• all involuntary actions such as walking

• it's the gray matter on the surface of the cerebrum

What is the function of the pons?

• functions as a bridge between the cerebrum and cerebellum

• processes inputs of cerebral cortex and sensory receptors

• controls all involuntary actions

What does the cerebellum do?

• function in arousing and maintaining consciousness

• processes inputs of cerebral cortex and sensory receptors

• deficiency of the neurotransmitters dopamine

What neurons are involved in a reflex arc? Check all that apply.

• sensory

• interneuron

• motor neuron

• connective tissue

What is white matter?

• axons with myelin

• cell bodies, axons without myelin, dendrites, and neuroglia

What is gray matter?

• axons with myelin

• cell bodies, axons without myelin, dendrites, and neuroglia

What is a synapse?

• controls movements of skeletal muscles, speech, and eyes

• gap between neurons that allow action potential to move from one neuron to the next neuron

What part of the brain controls movement of the skeletal muscles?

• cerebellum

• diencephalon

• medualla oblengata

What do Axons do?

• carry information to the cell body

• carry information away from the cell body

What are axons covered in?

• myelin sheath

• capillaries
