What do sense organs do? |
Contain receptors which detect stimuli |
|
|
What is the pathway of a response to stimuli? |
Receptor - sensory neurone -CNS - motor neurone - effector |
|
|
What is the pathway of a reflex action? How does this differ from a regular response? |
Receptor - sensory neurone - relay neurone - motor neurone - effector
A reflex action bypasses the CNS |
|

Stages of the menstrual cycle |
1 the uterus lining breaks down for 4-7 days
2 the lining of the uterus builds up again from day 7-14, into a thick spongy later full of blood vessels ready to receive a fertilised egg
3 an egg is developed an released from the ovary at day 14
4 the wall is then maintained for about 14 days, until day 28. If no fertilised egg has landed on the uterus wall by day 28, the spongy lining starts to break down and the whole cycle starts again |

Purpose of FSH |
Causes and egg to develop in one of the ovaries and stimulates the production of oestrogen |

Purpose of oestorgen |
Causes the lining of the uterus wall to thicken and grow and stimulates the production of LH/inhibits FSH production |
