What is a sensory neurone? - CORRECT ANSWER-A neurone that
carry information from the receptors to the CNS.
What is a relay neurone? - CORRECT ANSWER-Neurones that carry
impulses from the sensory neurone to the motor neurone.
What is a motor neurone? - CORRECT ANSWER-Neurones that carry
information from the CNS to the effectors.
What is the nervous system? - CORRECT ANSWER-It is a system that
allows you to react to your surroundings.
How do signals travel across a synapse? - CORRECT ANSWER-The
chemical or neurotransmitter diffuses across the synapse and
binds to a complementary receptor on the neurone
(postsynaptic). This causes an electrical impulse to travel down
the next neurone.
,What is a synapse? - CORRECT ANSWER-A gap between two
neurones.
What is the thermoregulatory centre of the brain? - CORRECT
ANSWER-Near the hypothalamus, monitors the temperature of
blood.
Describe the stages in a reflex arc. - CORRECT ANSWER-Stimulus-
>Receptor->sensory neurone->CNS (relay neurone) -> motor
neurone -> effector -> response
Name responses that reduce body temperature. - CORRECT ANSWER-
Hairs lie flat, sweat and blood vessels get wider(vasodilation)
What happens during vasodilation? - CORRECT ANSWER-The blood
vessels supplying the skin dilate (widen). This helps to transfer
energy to the environment.
Name responses that increase body temperature. - CORRECT
ANSWER-Hairs stand up, no sweat, shivering and blood vessels
constrict(vasoconstriction)
What happens during vasoconstriction? - CORRECT ANSWER-The
blood vessels supplying the skin constrict to close off the skins
blood supply.
What is the body's core temp? - CORRECT ANSWER-37 degrees
Celsius
,What are hormones? - CORRECT ANSWER-Chemical messengers that
travel in the blood to target organs.
Compare and Contrast the endocrine (hormone) system and the
nervous system. - CORRECT ANSWER-Nervous is faster acting than
the endocrine system.
Hormones have longer lasting effects compared to electrical
impulses. Nerves act on a very specific area whereas hormones
act more general.
What does the thyroid gland do? - CORRECT ANSWER-Produces
thyroxine which is involved in regulating metabolism.
What do the adrenal glands do? - CORRECT ANSWER-Produce
adrenaline which is used to prepare the body for fight or flight.
What is the role of the pancreas? - CORRECT ANSWER-Produces
glucagon and insulin which are involved in regulating glucose
levels in the blood.
Name the hormone that is released if blood sugar is too high. -
CORRECT ANSWER-Insulin
What does insulin do? - CORRECT ANSWER-It makes the liver
convert glucose into glycogen. This causes blood glucose levels
to decrease.
Name the hormone that is released if blood sugar is too low. -
CORRECT ANSWER-Glucagon
, What does glucagon do? HINT GLU-COSE-GONE - CORRECT
ANSWER-It makes the liver convert glycogen to glucose. This
causes the blood glucose level to increase.
What is type I diabetes? - CORRECT ANSWER-When the pancreas
produces little or no insulin.
What is type II diabetes? - CORRECT ANSWER-When a person
becomes resistant to their own insulin. Being overweight can
increase your chances of type II diabetes.
How can type I diabetes be treated? - CORRECT ANSWER-Insulin
injections, limiting intake of foods rich is simple carbohydrates
e.g. sugars and regular exercise.
How can type II diabetes be treated? - CORRECT ANSWER-It can be
controlled by eating a carbohydrate controlled diet and getting
regular exercise.
What is the role of the kidneys. - CORRECT ANSWER-Kidneys make
urine by taking unwanted waste products out of your blood.
They are involved in selective reabsorption.
Name three things that are re-absorbed by the kidneys into the
blood. - CORRECT ANSWER-Glucose, water and ions.
Name three things that are removed from the body in the urine.
- CORRECT ANSWER-Urea, water and ions.
