Parts of the Nervous System

Which part of the neuron is labelled F?

• Myelin Sheath

• Dendrite

• Axon

• Cell Body

• Axon Terminal

Which term matches the following definition. a specialised cell transmitting nerve impulses. It is the most common cell in the nervous system.

• Central Nervous System

• Peripheral Nervous System

• Neurons

The part of the body that contain the nerve tissue (contains neuron cells) that connects the olfactory epithelium (smell receptors ) to the brain is the:

• olfactory epithelium

• mucus

• olfactory tract

• amygdala

Which part of the neuron is where the nucleus is located?

• Cell body

• Dendrite

• Axon

• Myelin sheath

Which part of the neuron is a thread-like structure that carries impulses to other neurons?

• Cell body

• Dendrites

• Axon

• Myelin sheath

Which part of the neuron is a fatty layer that insulates the axon and sometimes a dendrite?

• Cell body

• Dendrites

• Axon

• Myelin sheath

The Peripheral Nervous System is made up of

• the brain and spinal cord

• all of the neurons in the body

• the neurons outside of the brain and spinal cord

• the neurons in your arms and legs

What does the somatic system do? (the somatic system is part of the Peripheral Nervous System)

• It speeds up functions of the body ready for fight or flight

• it slows down functions of the body ready for rest and digest

• It consists of all the neurons outside of the Central Nervous System

• It is used for actions that you control (reaching out and grabbing something) and sensing stimuli

The Central Nervous System is made up of

• the cerebellum and cerebrum

• the brain and spinal cord

• the brainstem and spinal cord

• cerebrum and spinal cord

How does the body prevent damage to the fragile brain and spinal cord?

• the brain is kept floating in the skull so it can absorb impacts

• the brain and spinal cord are enclosed in bone (skull and spinal column) to protect it

• the spinal cord is kept safe by being hidden behind other body organs and muscles

• The brain isn't as protected as the spinal cord
