Cardiac & Vascular Disorders – Self-Quiz I Info from notes on 01/22/2013 ------------------------------------------------- Top of Form Name the 4 chambers of the heart‚ and where they receive blood from: Name the 3 muscle layers of the heart‚ give an example of where you would find these: Name the 2 AV Valves (Atrioventricular) and the 2 SV Valves (semilunar). Valves keep blood flowing in one direction‚ keeping blood in one chamber until the next chamber is ready. The first heart

NPB 101L Final Exam Review Lab 2 – Skeletal Muscle 1. Describe basic setup a. What was manipulated? Intensity‚ frequency b. What was measured? Twitch tensions c. What concepts were investigated? i. Frog‚ sciatic nerve‚ gastroc‚ d. What was investigated? i. Effects of stimulus frequency and intensity on contraction-the more intensity‚ the higher the twitch tension. The more freq- the more twitch tension (By ~4.0pps we start to see summation of the twitches and by ~15pps we see no single twitches

that can be stimulated by odor molecules. When stimulated‚ the golf protein stimulates the release of a cyclic AMP catalyzing enzymes. Upon catalyzing‚ the cyclic AMP acts as a transmitter signaling the opening of sodium ion channels resulting in depolarization of the receptor cells. Olfactory sensory information travels from the axon through the cribriform plate holes and mitral cell synapse. The mitral cells are located in the olfactory bulbs encompassing the olfactory tract. The data then travels

So by the constraints 1 < Cc < 3‚ we can conclude that the testing soil is not well-graded‚ but poorly graded. And the Cu obtained is 7.0513 > 6‚ which implies that the sample should be sand but not gravels. Furthermore

If the membrane reaches the trigger point‚ known as Threshold‚ what electrical potential will be generated? Action potential. b. During the depolarization phase‚ voltage-gated Na channels open and Na enters the cell. 4. What are the two processes that stop the potential from rising above +30 mV? a. Inactivation of voltage gated Na channels b. Opening of voltage gated K channels 5. a. The opening
