http://www.interactive-biology.com - In this video, I show the details of how the bending of the stereocilia on the inner hair cells results in the release of neurotransmitters, which ultimately results in hearing. Enjoy.

http://www.interactive-biology.com - In this video, I talk about the organ of corti, which is found on top of the basiliar membrane inside the cochlea. When the basilar membrane vibrates up and down, that causes the organ of Corti to move up and down, and the tectorial membrane in a windshield wiper-like fashion. This causes the cilia on the hair cells to bend, sending a signal to the brain. Enjoy :)

http://www.interactive-biology.com - In this video, I talk about how the brain processes information on the different pitches that we hear. I'm warning you - it starts off a little scary, but by the end of the video, you will have a good idea of how we hear different frequencies of sound.

http://www.interactive-biology.com - In this video, I show how Sound is accurately transferred to the inner ear. Since there is fluid inside the cochlea, impedance matching needs to take place. It happens due to the 1.3 to 1 ratio of movement between the maleus, incus and stapes and the difference in size between the tympanic membrane and the oval window. Watch the video for a full explanation.

http://www.interactive-biology.com - In this video, I talk about how hearing takes place, starting with the soundwaves entering the ear, hitting the eardrum, and being transfered to the internal ear. Enjoy the process. I hope you can hear it :)

http://www.interactive-biology.com - In this episode, I go into detail about how On Center, Off surround Ganglion cells respond to light that stimulates rods and cones in the center and the surround of the ganglion cell's receptive fields.

http://www.interactive-biology.com - In this video, I talk about the process of lateral inhibition, and how it enhances visual edges. I do that by putting two rectangles next to each other. Watch this video to see what happens.

http://www.interactive-biology.com - In this episode, I talk about receptive field of ganglion cells, showing how rods and cones are connected to bipolar cells that are then connected to Ganglion cells. The more bipolar cells you have connected to Ganglion cells, the larger the receptive field and the less detail you get. The opposite is also true. Watch the video for a thorough explanation.

http://www.interactive-biology.com - In this episode, I talk about the visual processing that happens in the retina, starting with the rods and cones, going to the bipolar cells and then the ganglion cells. Watch to learn how this process works. http://www.interactive-biology.com

http://www.interactive-biology.com - In this episode, I go through the process of how rods and cones respond to light. I use Rods as an example and show how Rhodopsin, Transducin and Phosphodiesterase are involved in the process. Enjoy

http://www.interactive-biology.com - In this episode, I give an introduction to how eyes work. Why do you see what you see? What is the mechanism involved in that process? Watch the video and see :)

http://www.interactive-biology.com - In this episode, I give a general overview of how senses work. I use the example of vision to illustrate a process that applies to all senses. Enjoy!

http://www.interactive-biology.com - In this episode, I talk about the thalamus and the hypothalamus and explain their roles in the nervous system. Enjoy!

http://www.interactive-biology.com - In this video, I talk about the medulla, pons and midbrain, the 3 parts of the brain stem and take a bried look at their functions.

http://www.interactive-biology.com - In this video, I talk about the function of the cerebellum and how it's involved in the coordination of movement.

http://www.interactive-biology.com - In this video, I talk about the 4 lobes of the Cerebrum: The frontal, parietal, occipital and temporal lobes. I also talk about the funfctions they are involved in. Enjoy!

http://www.interactive-biology.com - In episode 24, I respond to Nicodube23's question on How the Myelin Sheaths speed up the Action Potential through the process of Saltatory Conduction. Watch, learn and Enjoy!

http://www.interactive-biology.com - In this video, my wife helps me to demonstrate how reflexes work at the level of the neurons. We look at both the Knee jerk and eye blink reflexes and the mechanism underlying both. Enjoy! http://www.interactive-biology.com

http://www.interactive-biology.com - In this video, I respond to a question that was posted by Akbar on my blog. He asks about the difference between the inactive and closed states of v-gated sodium channels. I illustrate the difference using a box. Enjoy!

http://www.interactive-biology.com - In this episode, I talk about the general mechanism of addiction. How do people get addicted to drugs? Well, watch this video to find out. I also look at specific drugs like caffeine, cocaine, nicotine and LSD. Enjoy :)

http://www.interactive-biology.com - What would the skeletal system be without muscles to move our bones. Muscles are an essential part of what makes us humans and in this lecture, I talk about the three types of muscle, and more importantly, how they work. How does muscle contraction happen at the cellular level? Why does the heart beat on its own? What is actin and myosin and what happens to our muscles in response to exercise? These are a few of the questions I answer in this lecture. http://www.interactive-biology.com

http://www.interactive-biology.com - The skeletal system is an awesome structure, and is essential for the protection of our Internal organs, providing a framework for our bodies, producing blood cells and producing blood cells. In this lecture, I deal with the structure of its two main parts: The axial and appendicular skeletons, how bones are formed and details about the functions associated with the skeletal system. I end the lecture by talking about bone injury and disease, such as Osteoporosis. http://www.interactive-biology.com

http://www.interactive-biology.com - Section 34.1 deals with the Skin, starting with its structure, with the two layers: Epidermis and dermis. I also talk about the functions of the skin, from regulating internal temperature to functioning as a sense organ, producing vitamin D and protecting the underlying tissue. The lecture concludes with a discussion of what happens to the skin in response to an injury. http://www.interactive-biology.com

http://www.interactive-biology.com - In this episode, I talk about the concept of facilitation and explain how it results in a stronger signal in the postsynaptic cell.

http://www.interactive-biology.com/ - In this lecture, I first deal with the functions of the digestive system. We then take a journey through the digestive system by following your food from your mouth all the way through your body and even through the elimination of waste. I also talk about enzymes like amylase in the saliva, pepsin in the stomach and bile from the liver and how those enzymes help in the process of digestion. So go ahead and join me on this journey through the digestive tract. http://www.interactive-biology.com
