Parts of the Central and Peripheral Nervous System

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

PNS stands for

• Parallel Nervous System

• Peripheral Nervous System

• Physical Nervous System

• Pressure Nervous System

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 Peripheral Nervous System is divided into the Somatic System and the Autonomic System

• True

• False

This system detects stimuli with receptors.

• Somatic

• Autonomic

• Peripheral

• Sympathetic

Sensory neurons and Motor neurons are apart of what system?

• Somatic

• Sympathetic

• Autonomic

• Central nervous system

An impulse is travelling along an axon. It reaches a synapse, what happens next?

• The impulse jumps the gap to the dendrite of the next neuron and continues on its way

• Neurotransmitters are released into the synapse, which bind to the next neuron, generating an impulse in that neuron

• Dopamine is released into the synapse, which binds to the next neuron, generating an impulse in that neuron

• The impulse waits while the next neuron prepares itself to receive the signal
