The place on the stationary bone that is connected via tendons to the muscle is called the origin. The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position.

If you were to trace your finger across the wave in the diagram above, you would notice that your finger repeats its path. At any given moment in time, a particle on the medium could be above or below the rest position.

A third class lever is a system in which the fulcrum is at the end of the lever and the effort is between the fulcrum and the load at the other end of the lever. In the abdominal region, there are several sets of wide, flat muscles.

Muscles that need a lot of strength to perform their function—like leg or arm muscles—have many muscle cells in each motor unit. In vertebrates, voluntary muscles require action potentials electrical signals in their nerves to initiate every contraction.

Motor Units Nerve cells called motor neurons control the skeletal muscles. These muscles make up an antagonistic pair. The positive ions form an electrochemical gradient to form inside of the cell, which spreads throughout the sarcolemma and the T-tubules by opening even more ion channels.

If the motor neuron provides many nerve impulses in rapid succession, the muscle may enter the state of tetanus, or complete and lasting contraction. Synergists are muscles that help to stabilize a movement and reduce extraneous movements.

When we exert ourselves more than normal, the extra muscle contractions lead to a rise in body temperature and eventually to sweating.

What substance are nails made of? The human body is an amazing structure which contains a wide range of complex parts and processes.

As the antagonist for this motion, the triceps brachii muscle extends the arm at the elbow. There are three classes of levers, but the vast majority of the levers in the body are third class levers.

A wave is a repeating pattern. In the leg, there are muscles called adductors whose role is to adduct pull together the legs. The outside layer of skin on the human body is called the?

Tendons in the legs of mammals serve as springs, reducing the energy cost of running: Answer as many questions as you can before scrolling down to check your answers.

The bones that make up your spine are called what? Muscles of the human forearm anterior view, superficial layer. The Wave Equation A transverse wave is a wave in which the particles of the medium are displaced in a direction perpendicular to the direction of energy transport.

A muscle with three origins is a triceps muscle. Finally, the direction in which the muscle fibers run can be used to identify a muscle.

Oxygen debt or recovery oxygen uptake is the name for the extra oxygen that the body must take in to restore the muscle cells to their resting state. Similarly, the amplitude can be measured from the rest position to the trough position.

The two holes in your nose are called? Its gross appearance is familiar as meat or as the flesh of fish. Sarcomere Structure Sarcomeres are made of two types of protein fibers: The bones around your chest that protect organs such as the heart are called what? Holding an object still and maintaining posture are also the result of isometric contractions.

In vertebrates, all voluntary muscles are striated, and all involuntary muscles are smooth, except for cardiac muscle, which is involuntary but striated. There are three types of muscle tissue: Some muscle fibres are several centimetres long, but most other cells are only a fraction of a millimetre long.

The breast muscles are the main muscles of the wings, which are used by chickens only for occasional short bursts of flight. Tropomyosin is moved away from myosin binding sites on actin molecules, allowing actin and myosin to bind together.

The wave shown above can be described by a variety of properties. Also, learn more about advances in DNA health testing that help us understand genetic risk of developing early-onset primary dystonia.A longitudinal wave is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport.

A longitudinal wave can be created in a slinky if the slinky is stretched out horizontally and the end coil is vibrated back-and-forth in a horizontal direction. ANATOMY ATLASES & IMAGE DATABASES Anatomy Atlases & Image Databases Related Centers. FOR CT, CAT, MRA, MRI, X-RAY, ULTRASOUND ETC.
