1.     Describe the functions of the hypothalamus and hippocampus. What part of the brain are these structures located in?

The Hypothalamus is located near the pituitary gland.  The function of the Hypothalamus is releasing hormones, regulating body temperature, food intake, water balance, heart rate, blood pressure (BP), the menstrual cycle, and circadian rhythms. The Hippocampus is located in the temporal lobe. And its functions are long term memory, particularly of places and this is also used for learning purposes as well.

How are beta cells related to proteins and DNA?

Cell migration is essential throughout our lives, from early embryonic development to homeostasis through our adult lives. However, cell migration needs to be controlled and aberrant cell migration can have severe clinical consequences, including cancer. It has been reported that stiff tissues result in more aggressive cancer development than soft tissues, meaning that the composition of our tissues, including the extracellular matrix has a profound effect on our susceptibility to cancer. Using your understanding of lectures 29-33, what components and properties of extracellular matrix affect tissue stiffness and what properties of cell behaviour are likely to be affected by that stiffness.
