Your body uses neural circuits to: 1) generate & send electrical signals to your brain and spinal cord about stimuli impinging on you (light, sound, touch, temperature, pH, osmolarity, etc) 2) respond appropriately – by producing responses in various tissues (skeletal muscle, cardiac muscle, smooth muscle, glands, other nerve cells) So let’s learn how: ** nerve cells generate & send signals ** these produce responses in targets the plumber says... Your body also sends chemicals around the body via the blood – ‘hormones’ – to control body functions. 1) hormones reach their targets more slowly, and produce responses that are often slower and more long-lasting (than responses to neural inputs) 2) helps control neural development, digestion, metabolism, stress responses, reproduction 3) help determine cell birth, development, death So let’s learn how: ** hormones alter cell &organ function ** hormonal & neural inputs work together (in some cases) consider 2 approaches to understanding organ systems npb101-w2012-ishida Molecular mechanisms, higher functions (perception, memory, emotion), modeling, diseases are topics for other courses Look around you. Notice that terrestrial vertebrates are collections of cells on dry land. w w w . b l u e p l a n e t b i o m e s . o r g As evolutionary biologists and ecologists, you might ask “why?” For example, if this primate took several days to walk across the landscape shown here, what problems would it face & how will it solve these problems? As physiologists, we will spend this quarter asking “how”? That is, what structures & functions of its body enable it to survive? Loris tardigradus www.smh.com.au/.../2006/06/27/1151174196706 npb101-w2012-ishida To begin with, the concentration of water in the air is less than inside us. To estimate this, compare the H 2 O inside an average person vs. the H 2 O in air even on a humid day Since air is so much “drier”, we tend to lose water....
