- Hormones
- Follicle stimulating hormone (FSH) - Brain
- Lutenising hormone (LH) - Brain
- Oestrogen and Progesterone - Ovarys
- Oestrogen is secreted from the pituitary gland
- FSH causes the eggto rise - and more secretion of oestrogen
- Oestrogen contributes to the secretion of LH

- Nerves
- The nervous system
enables us to react
to our surroundings.
It consists mainly of
the brain, the spinal

("neurones" and
receptors.
- A reflex is a movement in response to a stimulus.

- The nervous system is a
network of nerves that flow
around your body and allow

around you.
- Effector - a
part of the

produces a
response
following a
stimulus
- Receptor - recieves the pain signal
- Relay - passes the message
- Sensory neurone -
- Motor neurone - neurone that connects the muscle to
the spine
- The connection of two neurones is called a synapse
