Human Physiology/Senses ← The Nervous System — Human Physiology — The Muscular System → Senses Are the physiological methods of perception. The senses and their operation‚ classification‚ and theory are overlapping topics studied by a variety of fields. Sense is a faculty by which outside stimuli are perceived. What are Senses? We experience reality through our senses. A sense is a faculty by which outside stimuli are perceived. Many neurologists disagree about how many senses

Background information: 1) What is diffusion? Movement of a particular type of molecule from an area of high concentration to an area of low concentration. 2) How is diffusion used by living cells? Living cells bring in food‚ water and oxygen‚ and excrete wastes through the process of diffusion 3) List two body systems in vertebrates that are dependent on diffusion Digestive system and respirational system 4) What is meant by the term metabolism the chemical processes that occur within a

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers

Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass. 349 out of 2.37 million males aged 5-24 were reported to have DMD or BMD in the United States. This means that about 15 of every 100‚000 males aged between 5-24 were affected that year. Also‚ a close friend of mine had muscular dystrophy so it played a role in my life. I wanted to know if it could be cured and if not was there any treatments for it. Muscular dystrophy could potentially be cured through

1. Paracrine signaling A) involves secreting cells acting on nearby target cells by discharging a local regulator into the extracellular fluid. B) requires nerve cells to release a neurotransmitter into the synapse. C) occurs only in paracrine yeast cells. D) has been found in plants but not animals. E) involves mating factors attaching to target cells and causing production of new paracrine cells. 2. Which of the following is true of synaptic signaling and hormonal signaling? A)

Unit II Test Review Chapter 4 BB Notes Cells Under the Microscope Cells are microscopic in size. Although a light microscope allows you to see cells‚ it cannot make out the detail that an electron microscope can. The overall size of a cell is regulated by the surface-area-to-volume ratio. 4.2 The Plasma Membrane The plasma membrane of both prokaryotes and eukaryotes is a phospholipid bilayer. The phospholipid bilayer regulates the passage of molecules and ions into and out of the cell. The
