33.1 and 33.2 The Nervous System

The Central Nervous System is made up of which TWO parts (pick two)

• Brain

• Axons

• Senses

• Spinal Cord

The three main regions of the neuron are

• sensory, inter- and motor

• cell body, axon, dendrites

• membrane, cytoplasm, genetic material

Impulses are sent through the nervous system using

• the immune system

• electrical and chemical changes

• radio and wireless signals

• blood cells

The three kinds of neurons are

• sensory, inter- and motor

• cell body, axon, dendrites

• membrane, cytoplasm, genetic material

What is the order in which neurons send impulses in a reflex arc?

• Interneuron

• Sensory neuron

• Motor Neuron

Dendrites

• receive signals and impulses and send them to cell body

• take nerve impulses from the cell body to other neurons / muscles

• contains the nucleus and organelles to keep this specialized cell functioning

Axon sections

• receive signals and impulses and send them to cell body

• take nerve impulses from the cell body to other neurons / muscles

• contains the nucleus and organelles to keep this specialized cell functioning

The cell body of a neuron

• receive signals and impulses and send them to cell body

• take nerve impulses from the cell body to other neurons / muscles

• contains the nucleus and organelles to keep this specialized cell functioning

Damaging this part of the brain potentially disrupts the ability to do higher-order things such as making complicated plans.

• hypothalamus

• cerebellum

• cerebrum

• brain stem

Neurons are a type of

• dendrite

• membrane

• organelle

• cell
