What are the two type of nervous system?
Central nervous system + Peripheral nervous system
Central nervous system + Cranial nervous system
Cranial nervous system + Spinal nervous system
Spinal nervous system + Central nervous system
What is the generalised order during a nervous response?
Receptor → stimulus → neurones → effector → response
Response → receptor →neurones → effector → stimulus
Stimulus → receptor → neurones → effector → response
Stimulus → effector → neurones→ receptor → response
Responses are carried out by organs or tissues known as
Stimulus
Responses
Effectors
Receptor
The diagram shows a cell.
What type of cell is shown?
ciliated cell
motor neurone
relay neurone
sensory neurone
The diagram shows a neurone carrying an impulse.
Which answer describes the type of neurone and the direction of impulse?
type of neurone = motor; direction of impulse = towards the spinal cord
type of neurone = motor; direction of impulse = away from the spinal cord
type of neurone = sensory; direction of impulse = towards the spinal cord
type of neurone = sensory; direction of impulse = away from the spinal cord

What type of neurone is shown on this image as purple?
Sensory
Motor
Relay
Synapse
The diagram shows a neurone.

Which statement about light receptors in the retina of a normal human eye is correct?
The cones only work in dim light
The rods are found in the fovea.
There are three types of cone.
There are three types of rod.
Which structure of the eye contains light receptor cells?
Retina
Lens
Cornea
Iris
How does lens help us see objects that are far?
It stays the same
It becomes fatter
It becomes flatter
It becomes more spherical
What do we refer to when we say "accommodation"?
How eye is adapted for converting light
How eye is protected from too much light
How eye reacts to too little light
How eye is adapted to see near or far
What is the main advantage of nervous response over chemical response?
Nervous response is safer
Nervous response lasts longer
Nervous response is unconscious
Nervous response is quicker
What is the chemical used by a neuron to transmit an impulse across a synapse to another nerve cell?
Neurotransmitters
Synapse
Threshold
Impulse
Name structure A
Collecting duct
Proximal convoluted tubule
Distal convoluted tubule
Glomerulus

liver
bladder
pancreas
heart
What are hormones?
specialized cells that destroy bacteria an viruses
chemical messengers that are produced in one type of tissue and cause changes in another type of tissue.
chemical messengers that are produced in bone marrow that are used to control body function.
specialized cells that control growth and metabolism.
