Test 6 - Nervous System (23)

Part of the brain that controls the most basic functions of life

• cerebrum

• cerebellum

• brainstem

• diencephalon

Brain is surrounded by membranes called

• thalamus

• meninges

• cerebellum

• medulla

part of the neuron that holds the major cell organelles like the nucleus

• axon

• dendrite

• cell body

• terminal

division of the peripheral nervous system that carries impulses away from the brain and connects to a muscle or gland to cause a response

• sensory/afferent

• motor/efferent

• somatic

• autonomic

which of the following is not one of the sections of the brain stem

• cerebellum

• medulla

• pons

• midbrain

an action potential consists of multiple steps - the first two parts are ___ (when the Na+ moves into the cell changing the cell to positive) and ___ (when the K+ moves out of the cell changing the cell back to negative)

• hyperpolarization, depolarization

• hyperpolarization, impulse

• repolarization, depolarization

• depolarization, repolarization

which is not one of the basic functions of the nervous system?

• detecting a change/stimulus

• rapidly sending signals from one part to another

• determining a response

• producing major body fluids

neuroglial cells help the neurons to function better, cells that produce myelin sheath along the axons (to send faster messages) are called

• astrocytes

• ependymal

• oligodendrocytes/schwann cells

• microglial

the neuroglial cells that connect the neuron to the blood vessel to control the chemical environment of the neurons/brain are called

• astrocyte

• ependymal

• oligodendrocyte/schwann cell

• microglial

a rapid, predictable response that is extra fast because it can be interpreted by the spinal cord is called a

• synapse

• reflex

• efferent response

• smooth muscle
