Mini - assignments for biological rhythms 1. Outline what we mean by an endogenous pacemaker (3) Endogenous rhythms are rhythms that aren’t imposed by the environment but generated from within the organism. Since many of our biological cycles follow an approximation 24-hour rhythm‚ even in the absence of external stimuli‚ it follows that there must be some kind of internal biological clock. 2. What is the name given to external events that play a role in rhythmic activities? Give
Premium Circadian rhythm Sleep Menstrual cycle
Controlled by a tear drop shaped area in the hypothalamus called The Suprachiasmatic Nucleus (SCN) All other clocks take their cue from SCN. The SCN itself is kept in synch with day-night patterns by a hormone ‘Melatonin’ secreted by the Pineal gland. Insomnia is correlated with and has been treated with low Melatonin levels • Way to test these cycles: Free running experiments. Here you very carefully remove people from the natural environmental stimuli. You take them to a building

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. Anatomy: The branch of science concerned with the bodily structure of humans‚ animals‚ and other organisms‚ esp. as revealed by dissection. Physiology: The branch of biology that deals with the normal functions of living organisms and their parts. Anatomy and physiology are connected in

connection has become an integral part of modern medicine (Goodwin‚ 2008). His dualist view‚ asserted the mind was ethereal and autonomous in relation to the physical and strictly material body‚ and to account for their interaction‚ he proposed the pineal gland was where the intersection of the two transpired (Goodwin‚ 2008).

Descartes states that the mind and the body are two separate entities that possess different characteristics.
