Very detailed explanation of the nerve impulse within a muscle. Shows how the action potential reaches the synapse and moves across to the receptors on the next nerve's dendrites. Shows changing of the ions to change the action potential. Animation with narration. Grades 9-12. 2:18 min.
The Urinary System
The urinary system is concerned with the formation and elimination of urine. In an adult, more than 2,500 pints of blood passes through the kidneys each day. Blood enters via the renal arteries and is filtered to remove most of the waste products of metabolism. Seven pints of filtrate are produced every hour. Purified blood returns to the body circulation via the renal veins. The filtering process is carried out by more than two million tiny kidney units, or nephrons, which produce a highly conc
Many of the body's most basic functions are regulated by the endocrine system—eight different glands located throughout the body. The endocrine system constantly and quietly does its work—secreting liquid chemical messengers called hormones. These chemicals manage muscle growth and digestion, as well as energy, reproduction, and more. This 3-D animation shows the hormones as they move through the body. Grades 7-12. 1:02 min.
Short video clip shows how a vein contains one-way valves that work in conjunction with skeleto-muscles. When the sceleto-mucles contract, the valve open and blood is forced toward the heart. When the sceleto-muscle relaxed, the valve closed to prevent the backflow of blood away from the heart. Grades 5-12. 19 sec.
Student Review of the Major Skeletal Muscles
This video uses a model to point out each of the major human skeletal muscles using the proper pronunciation, although the student stumbles a bit over the names at times. It would be a good video for students to use as a review before a lab muscle practical. All student made video with sound.

Pronounce the Muscles (Part 2)
Video has a list of major muscle names, beginning with letters G through M. The narrator pronounces the muscle names, and then allows the student to practice pronunciation. Words are a little blurry. Grades 9-12. 3:29 min.
Pronounce the Muscles (Part 3)
Video has a list of major muscle names, beginning with letters O through R. The narrator pronounces the muscle names, and then allows the student to practice pronunciation. Words are a little blurry. Grades 9-12. 2:48 min.
Pronounce the Muscles (Part 4)
Video has a list of major muscle names, beginning with letters S through Z. The narrator pronounces the muscle names, and then allows the student to practice pronunciation. Words are a little blurry. Grades 9-12. 4:21 min.
Shows how ATP molecules are used to make the myosin move and push the actin fiber to make the muscle contract. Narrated animation with labels for the parts; very detailed. Grades 9-12. 58 sec.
Magic School Bus Gets Energized
Join Ms. Frizzle and the class as they learn more about the different sources of energy. The class plugs their Double-Trouble Wheel of Wonder, the hottest ride at the school carnival, when their electricity fails. No electricity, no ride! Carlos' younger brother Mikey helps them discover that there are other sources of energy besides electricity. Using wind, water, the heat of the sun, falling rocks, and their own muscle power, the class gets the Ferris wheel running. Run time 22 minutes.
Charming Snakes- Cobras in the Dark
Cobras are one of the most poisonous snakes in the world. Their most
distinctive feature is their hooded head which they raise to intimidate
prey as it spreading their hood makes them look larger.
Cobras usually eat rodents, eggs, and frogs; but they also eat other
snakes such as rat snakes. Their venom is a neurotoxin and when injected
into prey, it paralyses the animal by shutting down the function of the
nervous system, which ultimately leads to cardiac
Role of the Sarcoplasmic Reticulum in Muscle Cells
The instructor in this video, Sal Khan, discusses the role of the sarcoplasmic reticulum in controlling calcium ion concentrations within the muscle cell. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
Cat Dissection: Thorax
Cat muscle review of the chest region: Pectoralis major, pectoralis minor, xiphuhumeralis, & serratus ventralis. Student produced.
Review of Cat Muscles of the Back and Posterior Arm
Specific muscles of the back and posterior arm of a dissected cat are reviewed with proper pronunciation. Origin, insertion, and functions are given. This would make a great review for students preparing for a cat muscle practical. Color video with sound. Run time 05:43.
Cat Muscles of the Upper Arm
This video shows the arm muscles of a cat as well as the function(s) of each individual muscle, including the 3 parts of the triceps. biceps, brachialis, and brachioradialis. Student produced video of instructor review.
Review of Cat Muscles of the Anterior Leg
Specific anterior muscles of the leg of a dissected cat are reviewed with proper pronunciation by a professor. Origin, insertion, and functions are given. This would make a great review for students preparing for a cat muscle practical. 3:51 min. Color video with sound.
Review of Cat Organs and Blood Vessels
Professor reviews major blood vessels. Comparisons to human anatomy are made. Trachea, larynx, spleen, pancreas, and kidneys are also identified. This would make a great review for students preparing for a cat muscle practical. Color video with sound. Run time 07:01.
