E2 Perception of stimuli
E.2.1 Outline the diversity of stimuli that can be detected by human sensory receptors, including
mechanoreceptors, chemoreceptors, thermoreceptors and photoreceptors.
Details of how each receptor functions are not required.
E6 Further studies of behaviour
E.6.1 Describe the social organization of honey bee colonies and one other non-human example.
Detailed structural differences and the life cycle of honey bees are not expected.
Honey bee colony
Honey bee colonies are organ
E5 The human brain
E.5.1 Label, on a diagram of the brain, the
medulla oblongata, cerebellum, hypothalamus,
pituitary gland and cerebral hemispheres.
I. cerebrum / cerebral hemisphere
V. spinal cord / medulla
E3 Innate and learned behaviour
E.3.1 Distinguish between innate and learned behaviour.
Innate behaviour develops independently of the environmental context, whereas learned behaviour
develops as a result of experience.
E.3.2 Design experiments to investi
E4 Neurotransmitters and synapses
E.4.1 State that some presynaptic neurons excite postsynaptic transmission and others inhibit
Some presynaptic neurons excite postsynaptic transmission.
Some presynaptic neurons inhibit postsyna
H.2.1 State that digestive juices are secreted into the alimentary canal by glands, including salivary
glands, gastric glands in the stomach wall, the pancreas and the wall of the small intestine.
food is digested as it passes along the alim
H3: Absorption of Digested Foods
H.3.1 Draw and label a diagram showing a transverse section of the ileum as seen under a light
microscope. Include mucosa and layers of longitudinal and circular muscle.
H.3.2 Explain the structural features of an epitheli
Discuss the concept of brain death and the use of pupil reflex in testing for brain death (6)
Whole brain death is brain stem and cerebrum;
Failure of pupil to respond to light indicates brain stem death;
w/p brain stem function, life cannot cont
Distinguish between mode of action between steroid hormones and protein hormones
steroid hormones enter cell while protein hormones bind to specific membrane receptors / steroid hormones can pass through
cell membranes while protein hormones cannot;
Neurobiology and Behaviour
E.1 Stimulus & response:
E.1.1 Define the terms stimulus, response, and reflex in the context of animal behavior.
A stimulus is a change in the environment (internal or external) that is detected by a receptor and elicits a re
H6: Gas Exchange
H.6.1 Define partial pressure: pressure exerted by each by each gas in a mixture of gases
In air, oxygen excerpts approx 21% of the total pressure.
Oxygen partial pressure = total pressure X 21%
At low pO2,hemoglobin is not fully satura
H4: Functions of Liver
H.4.1 Outline the circulation of blood through liver tissue, including the hepatic artery, hepatic portal
vein, sinusoids and hepatic vein. The difference in structure between sinusoids and capillaries should also be
H5: Transport System
H.5.1 Explain the events of the cardiac cycle, including atrial and ventricular systole and diastole, and
Contraction of chambers=systole, relaxation=diastole
Contraction of atrium wall
