Q.C. Science Department
The cerebrum is involved in _______________________________ and ___________________ (particularly the
arms and legs).
It also helps us to register __________________________
And to make _______________________
_______________________ portion of the brain
Consists of 2_____________________________ (left and right)
Responsible for intelligence, memory, consciousness, reasoning, acquired skills (mathematics, speech, playing
music)
It is this part that is also thought to be responsible for our ________________________________.
Roles of the cerebellum
•
•
Dark ridged structure at the back of the brain beneath the __________________________
Controls _____________________, ___________________________ and coordination of
_________________.
Roles of the medulla oblongata
•
•
•
Controls _________________________involuntary responses. e.g. Heartbeat and breathing.
________________________________ center of the brain.
Controls _________________________________, coughing, swallowing, yawning, sneezing and vomiting.
The Hypothalamus and the pituitary gland
•
•
Hypothalamus- Controls ___________________________. The hypothalamus monitors blood-sugar levels,
temperature control, water balance and carbon dioxide levels in the blood.
The pituitary gland ( _______________________________) produces hormones in response to this. Controls
growth and the other endocrine glands.
•
Nerves that run from our sense organs (RECEPTORS) to our CNS (carrying information about the environment).
Nerves that run from our CNS to our effectors (either _____________ or __________)
Lesson #2
Lesson Objectives:
1. Differentiate between neurons of the nervous system
2. Describe how reflex actions help protect the body from damage.
3. Explain the route through a reflex arc.
There are three types of neuron:
____________________________ neurons- detect changes in the environment, send signals to CNS.
______________________________ neurons- Pass signals from the sensory to the motor neuron.
______________________________neurons- send signals to muscles and glands.

Nervous System
Q.C. Science Department
Sensory neurons carry impulses from the receptor to the CNS. Receptors detect stimuli and convert them to an electrical
impulse. Sense organs are receptors.
Associate/Intermediate/Relay/ Connector neuron forms a link between sensory and motor neuron. They are located in
the brain and spinal cord. They also run throughout the CNS connecting the brain and spinal cord.
Motor neuron carry nerve impulse from the CNS to effectors. Effectors bring about a response to stimuli. Muscles and
glands are effectors
Grey matter is made up of __________________________ (and nuclei).
White matter is made up of ______________________________
When a _____________________________ is stimulated, it sends a signal to the _________________________ nervous
system, where the brain co-ordinates the_______________________________.
Sometimes a very quick response is needed, one that does not need the involvement of the brain. This is a reflex action.
An _______________________ response to a stimulus
Reflex actions are involuntary quick responses to a
stimulus.
•
•
•
•
Innate
_____________________________
_____________________________
Done in response to an environmental stimulus.
Reflex actions are part of the autonomic system.
This is the _________________________________ part
of the body that also controls heart rate, breathing rate,
digestion and sexual arousal.

Types of Reflexes
Grade:___
Nervous System
Date:______________________
Q.C. Science Department
____________________________ reflexes are inherited and do not have to be learnt.
Examples:
knee-jerk reflex
Pupil reflex
____________________
_______________________
Producing saliva
Response to pain
_________________________reflexes are actions which have to be learnt before they become automatic.
Examples:
Talking
reading
___________________
playing an instrument
driving a car
____________________________
Conditioned reflex
This is a type of learnt reflex where the response has no natural relationship to the stimulus.
Example: Pavlov’s dog producing saliva in response to a bell.
