- Each organised skeletal muscle in our body is made of a number of muscle bundles or fascicles held together by a common collagenous connective tissue layer called fascia.
- Each muscle bundle contains a number of muscle fibres and each muscle fibre is lined by the plasma membrane called sarcolemma enclosing the sarcoplasm.
- Muscle fibre is a syncitium as the sarcoplasm contains many nuclei.

Slow-twitch fibers are also sometimes called type I or red fibers because of their blood supply. Fast-twitch muscle fibers provide bigger and more powerful forces, but for shorter durations and fatigue quickly

Your body has two types of skeletal muscle fibers: slow-twitch (type I) and fast-twitch (type II).
Slow-twitch muscles give you the stamina to nail endurance tasks like distance running. People use fast-twitch muscles in explosive actions, like sprinting, jumping, or playing a cameo in a “Fast and Furious” movie. (If you have furious-twitch muscle fibers, seek medical assistance.)
During aerobic exercises like running or swimming, slow-twitch fibers are the first to contract. But when you’re throwing around heavy kettlebells or playing a sport, you’re using fast-twitch muscles.

An antenna – usually 1/2 wavelength long – split at the exact center for connection to a feed line. Dipoles are the most common wire antenna. Length is equal to 1/2 of the wavelength for the frequency of operation. In an instructable, the formula for calculating antenna length was given as "length in meters =300 / frequency in MHz". The example given was for a Bluetooth antenna with a frequency of 2450MHz. The antenna length was calculated as 300/2450 = 0.1225m = 12cm.

(iii) Asteya or Non-stealing : of anything in life such as money, material, ideas, speeches or writings. We should feel satisfied, whatever God has given us.

We asked prominent voices in education—from policy makers and teachers to activists and parents—to look beyond laws, politics, and funding and imagine a utopian system of learning. They went back to the drawing board—and the chalkboard—to build an educational Garden of Eden. We’re publishing their answers to one question each day this week. Responses have been lightly edited for clarity and length.

Voluntary muscles are long, multinucleated cells, containing sarcomeres arranged into bundles. These muscles are composed of cylindrical fibers and are usually attached to bones and the skin. They play an important role in allowing the body to move by contracting and relaxing and their actions are mainly under the control of the somatosensory nervous system. These voluntary muscles include skeletal muscles.
