
I can:

State that the CNS is made up of the brain and the spinal cord

Describe the function of the CNS as processing information from the
senses and bringing about appropriate responses

State that the CNS allows communication between cells in a
multicellular organism.

State that a stimulus is a change in conditions and is detected by
receptors.

Describe the role of sensory neurons as passing information to the
CNS.

Describe the role of motor neurons as enabling a response to occur.

State that responses brought about by the CNS may be fast, such as
those from a muscle or slow, such as those from a gland.

Explain that reflex actions are fast automatic responses which
require no input from the brain.

Describe examples of reflex actions, for example the pupil of the eye
becoming smaller in bright light to protect the sensitive cells at the
back of the eye from damage

Explain that reflex actions are important to protect the body form
harm

Describe a reflex are as the passage of an impulse from a sensory
neuron, across a relay neuron to a motor neuron

State that electrical impulses move along neurons

Describe a synapse as a gap between neurons that allows chemicals to
transfer form one neuron to another.

State that hormones are chemical messengers

State that endocrine glands release hormones into the bloodstream
where they travel to target tissues

State that target tissues have cells with special receptors for the
hormones on their surface

Explain that only tissues with a corresponding receptor will be
affected by a specific hormone.

State that a change in blood glucose levels is detected by the
pancreas

State that glucose can be stored as glycogen in the liver

Explain that when blood glucose level increases, the pancreas releases
more insulin, which travels to the liver where it activates enzymes in
the liver cells to convert glucose into glycogen

Explain that when the blood glucose level decreases, the pancreas
releases more glucagon, which travels to the liver where it activates
enzymes in the liver cells to convert glycogen into glucose.

Describe type 1 diabetes as a disease caused by lack of insulin causing
high blood glucose levels, treated by injecting insulin

Describe type 2 diabetes as a disease caused by lack of response to
insulin causing high blood glucose levels treated by diet and exercise

Explain that it is important to control blood glucose levels since, if
they are high, they can cause damage to blood vessels and affect the
functioning of the eyes and kidneys in particular

State that uncontrolled blood glucose levels can cause problems with
osmosis in cells.
