Vertebrate Physiology Study Guide Last Part of Chapter 10 □ Cilia are specialized for odor detection (They have receptors and second messenger machinery □ Mucus from the olfactory glands traps odorants □ Linda Buck identified a large family of odorant receptor genes in rats(1‚000 types); belong to the G protein associated 7-transmembrane receptor family □We only have 400 odorant receptors; the olfactory system appears to use combinations of receptors(words) to greatly reduce the number of

Location: medial/inner structure of the bodyy 3. Organs: bones‚ joints‚ and associated cartilages Muscular System: 1. Function: body movement‚ stabilizing body position/posture‚ generates heat 2. Location: on top of/attached to bones (skeletal) AND in certain organs (smooth) 3. Organs: skeletal muscles and smooth

Often we see that having eyestrain is just the beginning. Whenever you don’t see well other factors will play into it‚ like headaches‚ soreness‚ and fatigue. After working out though‚ we often have lactic acid buildup‚ which will cause fatigue and muscle weakness‚ so we must rule that out. 3. Why is Annie having problems breathing? Breathing is an involuntary function of the respiratory system. In the spinal cord there are nerves that are in charge of these involuntary functions. The apneustic

Week 2 Reading Summary : Chap 1-3 Chapter 1 Anatomy: studies the structure of body parts and their relationship to one another. Can be seen‚ felt‚ examined. Physiology: concerns the function of the body in other words‚ how the body parts work and carry out their life-sustaining activities Complementary of structure and function Function reflect structure‚ what a structure can do depends on is specific form Levels of structural organization: Cells – smallest living unit

Title: Grip Strength and Muscle Fatigue I. Purpose/Hypothesis: In this lab the subject will grip on a scale that measures the amount of force being put on it. We will observe the change in hand strength during continuous grip over time. Then we will also measure hand strength during rapid‚ repetitive gripping. I believe that hand strength will weaken during a continuous grip more than if you were to keep a repetitive grip. II. Procedure: 1. Connect the Hand Dynamomenter to LabQuest and select
