Explores the major characteristics of the skeletal and muscular systems. Discusses the number of bones in the human body, describes their different shapes and sizes, and illustrates how bones need muscles to move. Talks about different kinds of joints, and gives examples of how we use joints everyday.
Athletes demonstrate their flexibility in this look at our ingeniously designed muscular-skeletal system. Discusses muscle and bone interaction, their structure, purpose, and function. Comments on technological studies on motion.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ms. Frizzle takes the class with her when she brings the Magic School Bus to the body shop for repairs. While there, Ralphie wants to use extra parts at the shop to make a robot. Ms. Frizzle then teaches the class how bones, muscles and joints all work together to help us move.
Imagine if there were electronics able to prevent epileptic seizures before they happen, or electronics that could be placed on the surface of a beating heart to monitor its functions. The problem is that such devices are a tough fit. Body tissue is soft and pliable while conventional circuits can be hard and brittle--at least until now. Materials scientist John Rogers at the University of Illinois Urbana-Champaign is working to develop elastic electronics.
Tongue taste areas The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system. The tongue's upper surface (dorsum) is covered in taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is the enabling of speech in humans and vocalization in other animals. The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum) that results in a groove, the median sulcus on the tongue's surface. There are two groups of muscles of the tongue. The four intrinsic muscles alter the shape of the tongue and are not attached to bone. The four paired extrinsic muscles change the position of the tongue and are anchored to bone. Do you have good taste? In this video segment, Dr. Linda Bartoshuk explores the sense of taste in humans - why we have it, and what happens when we lose it. Learn why the sense of smell is also important to our experience of food. Footage from NOVA: "Mystery of the Senses: Taste".
Shows how the cerebellum coordinates muscle activity and how position sensors in the muscles and joints and the balancing mechanism of the inner ear function. The motions of a water-skier show the physical, interconnected structure of muscles, joints, and organs. The role of joints is explained, and a look at the interior of a human knee shows clearly how lubricating fluid is produced.
Hurricanes are nature's engines of death and destruction, the costliest natural disaster on earth. Explains how and where hurricanes formed; uses live footage to show the forces of wind, weather, and storm surge, and the damage they can do. Compares current information with historical knowledge and notes how forecasting has greatly improved. Explores how meteorologists work to understand and predict these brutal storms.
Storyteller Heather Forest uses song, pantomime, games, and discussion to introduce young students to the human body. Talks about key body parts and how they move; how the heart, lungs, and brain keep the body running; how the bones, joints, and muscles hold the body up and help it move; and how our senses help us enjoy the world. Introduces principles of healthy eating, daily exercise, and adequate rest.
In this episode, host Dianna Cowern investigates the biomechanics of butts. What activates one's butt muscles more, running or squatting? How effective are bridges as a workout? How much can individuals change the shape of their bodies with exercise? Dianna and Dr. Rowley conduct various experiments to answer these questions about anatomy and physiology. Part of the "Physics Girl" series.
Explains why the body needs regular supplies of air and how these get to the body. The camera follows the process of breathing through the ultra-thin membrane of the lung into the blood, showing how the varying demand for oxygen is met by the exchange of information between the brain and the chest muscles and how the body rids itself of carbon dioxide.
With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.
Shows how the brain coordinates functions to make simple but lifesaving decisions. Provides an overview of how the cortex assesses incoming information, sends outgoing messages to the muscles, and stores "maps" of the world and the body. Also outlines how circuits of nerve cells operate in the brain and how individual nerve cells function.
Shows the human body systems: lungs, heart, and skeleton. Demonstrates the structures of the lungs, heart, and arteries and veins. Explains exchange of gas in the lungs, ventilation of the lungs, and how the heart works as a pump. Also discusses the role of the skeleton in providing support, protection, and anchorage for muscles, the importance of bone marrow, and the importance of calcium in giving strength to bones.
Functional electrical stimulation technology (FES) is designed to interface technology with muscles and nerves in an attempt to restore some level of function for people with central nervous system disabilities. Visits several experimental programs that are using implanted electrodes, controlled by external computer devices, to enable people with spinal cord injuries to stand, transfer, and, under controlled conditions, even walk.
New developments in gene editing reveals that wild plants can be put on the fast track for domestication and the grocery store. Advances in astronomy have captured the inner working of the rare star known as luminous blue variables. Other segments include the use of macrophages to help heal injured muscles and new evidence shows that wildlife is thriving in the suburbs. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
With support from the National Science Foundation, aerospace engineer Michael Philen and his team at Virginia Tech are investigating the biomechanics of fish locomotion, in hopes of contributing to the next generation of robotic fish and underwater submersibles. They’re studying how fish use their muscles to swim efficiently and execute underwater maneuvers, such as darting around in perfectly synchronized schools. They’re also developing new smart materials, such as a bioengineered hair that is modeled after the hair cell sensors on the side of fish that allow it to detect minute changes in water flow. Part of the National Science Foundation Series “Science Nation.”
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. At this year's Teacherathalon, Ms. Frizzle squares off with Mr. Sinew, a muscle-bound gym teacher. Sinew easily wins the first of the three events. Thinking there's a problem, the kids go inside Ms. Frizzle to check her out. The bus takes them through her lungs to the bloodstream, where they get pumped through her heart to her calf muscle. But when Frizzle's leg muscle collapses from the strain of winning the second event, the kids discover that her red blood cells can't get oxygen to her muscles fast enough. Can the kids help Frizzle recover in time to win the final race?
