23 slides covering Hormones in human reproduction:
By the end of the powerpoint students would have covered:
4.5.3.4 Hormones in human reproduction
Students should be able to describe the roles of hormones in human reproduction, including the menstrual cycle.
During puberty reproductive hormones cause secondary sex characteristics to develop.
Oestrogen is the main female reproductive hormone produced in the ovary. At puberty eggs begin to mature and one is released approximately every 28 days. This is called ovulation.
Testosterone is the main male reproductive hormone produced by the testes and it stimulates sperm production.
Several hormones are involved in the menstrual cycle of a woman.
Follicle stimulating hormone (FSH) causes maturation of an egg in the ovary.
Luteinising hormone (LH) stimulates the release of the egg.
Oestrogen and progesterone are involved in maintaining the uterus lining.
(HT only) Students should be able to explain the interactions of FSH, oestrogen, LH and progesterone, in the control of the menstrual cycle.
(HT only) Students should be able to extract and interpret data from graphs showing hormone levels during the menstrual cycle.

17 slides covering The Brain.
By the end of the powerpoint students would have covered:
4.5.2.2 The brain (biology only)
The brain controls complex behaviour. It is made of billions of interconnected neurones and has different regions that carry out different functions.
Students should be able to identify the cerebral cortex, cerebellum and medulla on a diagram of the brain, and describe their functions.
(HT only) Students should be able to explain some of the difficulties of investigating brain function and treating brain damage and disease.
(HT only) Neuroscientists have been able to map the regions of the brain to particular functions by studying patients with brain damage, electrically stimulating different parts of the brain and using MRI scanning techniques. The complexity and delicacy of the brain makes investigating and treating brain disorders very difficult.
