What is the spinal cord?
A long thin column of nerves between the brain and peripheral nervous system
13 of 75
What is the brain stem?
The connection between the brain and the spinal cord
14 of 75
What is the brain?
It is divided into three major parts; the hindbrain (lower part), the midbrain, the forbrain
15 of 75
What does the Autonomic Nervous system do?
Regulates involuntary bodily processes including heart rate. It operates automatically without conscious direction
16 of 75
What does the Somatic Nervous system do?
It carries sensory information from sensory organs to the central nervous system and relays motor (movement) commands to muscles, and controls voluntary movments
17 of 75
What does the Sympathetic Nervous system do?
It prepares the body for action and stress. This is called "fight or flight"
18 of 75
What does the Parasympathetic Nervous system do?
It calms the body and helps the body to conserve energy "rest and digest"

24 of 75
What is the primary function of the nervous system?
To control behaviour/regulate bodily processes

What are Neurons that receive information from our sensory organs (e.g. eye, skin) and transmit this input to the central nervous system called?
afferent neurons
27 of 75
What nervous system does voluntary control (decision to drink) use?
Central nervous system and peripheral nervous system
28 of 75
You decide you want to drink, what happens first?
you felt the feeling of thirst due to the Autonomic Nervous system
29 of 75
After you have felt the feeling of first and decided you want a drink what happens next?
You give sensory input to the central nervous system via the somatic nervous system
30 of 75
You have decided you want a drink and given sensory input to the CNS. What happens next?
The information is integrated within the central nervous system
31 of 75
You have decided you want a drink and this information has been integrated in the central nervous system, what happens next?
The CNS gives motor output through the somatic nervous system and then you drink
32 of 75
What nervous system does simple reflects (e.g. motor neuron reflexes) use?
The central nervous system and the peripheral nervous system
33 of 75
You touch a hot iron what happens first?
The axon of sensory neuron detects pain and informs the somatic nervous system
34 of 75
You have touched a hot iron and your somatic nervous system has been informed of pain, what happens next?
The sometic nervous system causes an interneuron in the CNS to excite a motor neuron causing muscular contraction
35 of 75
You have touched a hot iron and the interneuron has excited the motor neuron what happens next?
The motor neuron causes the muscle to withdraw from the source of pain
36 of 75
Does the fight or flight response uses the Central nervous system or the peripheral nervous system?
Both
37 of 75
What happens when you see someone you like?
Your Somatic nervous system informs the CNS you have seen someone
38 of 75
You have seen someone you like and your Somatic nervous system has informed the CNS that you have seen someone what happens next?
The CNS recognises the person and has a sudden strong emotion
39 of 75
You have seen someone you like and the CNS has had a sudden strong emotion, what happens next?
The sympathetic nervous system is activated causing heart rate to increase, pupil dilation, goose bumps, dry mouth and blushing
40 of 75
What are the four neurons you need to know?
sensory neurons, motor neurons, interneurons, pyramidal neurons
41 of 75
What do motor neurons do?
Send signals to parts of the body, e.g. muscle and to direct movement
42 of 75
What do Pyramidal neurons do?
Are involved in many areas of cognition - such as object recognition within the visual cortex
43 of 75
What do sensory neurons do?
