What is a Sarcoplasmic Reticulum? Sarcoplasmic ... what? I know it's a long word, but it doesn't have to be scary. In this answer the question "What is a Sarcoplasmic Reticulum?" but in layman's terms. Explaining just the things you need to know for your Level 3 Anatomy and Physiology Exam If you watch until the end of the video then i have a special download for you too. Learning Point 1: Where is it? Let's have a quick recap of the sliding filament theory and structure of a muscle. The myofilaments, called actin and myosin, make up the sarcomere. A long row of sarcomeres makes up a muscle fibre or myofibril. The sarcoplasmic Reticulum surrounds each muscle fibre like a net. You can see it in this image as a blue river around the muscle fibre Learning Point 2: What is the Sarcoplasmic Reticulum? Essentially the sarcoplasmic reticulum stores and releases calcium for muscle contractions. If the words still seem to be a little daunting and confusing then breaking them down can help reinforce the name and the meaning. Sarco = Muscle Plasmic = Liquid Reticulum = Net like structure TOP TIP : The main thing you need to know for your Level 3 Anatomy and Physiology Exam is that the Sarcoplasmic Reticulum is responsible for the storage and the releasing of calcium; which is important for muscle contractions. Now you know everything you need to know about the sarcoplasmic reticulum, let's test your knowledge, with this Level 3 Anatomy and physiology Mock Question What Mineral is stored in the Sarcoplasmic Reticulum?

If you are looking to build muscle then you will want to know Myofibrillar hypertrophy or Sarcoplasmic hypertrophy which is better? Understanding this concept will help you to know the difference in hypertrophy that you will gain when training so you can decide whats the most effective way to train. Understanding hypertrophy or building muscle is important but many don't know there is a distinction between hypertrophy in the form of Myofibrillar hypertrophy and Sarcoplasmic hypertrophy. How you train ie intensity or rep range will determine which one of these 2 types of hypertrophy you will stimulate more of. want to just muscle muscle then go for sarcoplasmic hypertrophy as this is the fastest way to build size or to gain muscle fast, looking to get strong then the fastest way to gain strength is through myofibrillar hypertrophy but what if you want to gain size and strength? where you need to incorporate both forms of training and in this video i will explain how to do that and in another video on rep ranges i go into more details how different rep ranges stimulate different adaptations in the body, so you need to work in the right rep range for strength and the right rep range for size. So this will look at the difference between strength training and bodybuilding or calisthenics versus bodybuilding or comparing gaining strength over size.

Two Types of Muscular Hypertrophy There are two types of muscular hypertrophy; sarcoplasmic and myofibrillar. Lets explore both. Sarcoplasmic Hypertrophy Sarcoplasmic muscular hypertrophy involves an increase in the sarcoplasmic volume of a muscle cell with no corresponding increase in muscular strength. A strength increase is something you normally expect with an increase in muscular hypertophy, however sarcoplasmic volume increases serve very little to no functional purpose in terms of strength development. Sarcoplasmic hypertrophy is a response to hard training at relatively high volumes. In order for muscles to increase in size as a result of an increase in sarcoplasmic volume, they have to be trained within a higher repetition range. This is generally in the range of 8-12 and even beyond. This causes sufficient micro-trauma for the muscle to respond. Endurance athletes also experience a small level of sarcoplasmic hypertrophy in response to extremely high volumes of training. Obviously this form of muscular hypertrophy is not desirable for anyone aiming to increase strength or sports performance. Bodybuilders and those wanting beach muscles are likely the only ones concerned with sarcoplasmic muscular hypertrophy. This form or muscle size increase is the main reason you see strength to weight ratio decrease as a person gets larger, even with no evidence of excess body fat. It can seem a mystery to some as to why bodybuilders and frequent gym goers seem to be huge but only moderately strong. Myofibrillar Hypertrophy Myofibrillar muscular hypertrophy is what most people want. This is an increase in the size of the actual contractile proteins, resulting in more available muscle for contraction applied to resistance. This form of muscle increase is commonly seen in athletes that perform dynamic sports or strength and power. Weightlifters experience myofibrillar hypertrophy as a result of their training. When a load is lifted that is beyond 75% of maximum a corresponding increase in contractile proteins occurs in order to adapt and lift a heavier load next time. Myofibrillar muscular hypertrophy is attained through high intensity, lower volume training. However this is not always the case, it is just ideal. A muscle will not increase in strength to any great amount through repetitive lifting until fatigue. It doesn't make sense that lifting something 12 times will increase the amount you are able to lift in one-off efforts that are close to maximum strength. This is why myofibrillar hypertrophy occurs most notably as a result of training in the range of 3-7 repetitions. It's not ideal for a bodybuilder but it will build actual functional strength you can use and not unnecessary bodyweight. The size of the muscle will increase at a slower rate because the hypertrophy involves growth of functional units of muscular tissue as opposed to simply volume.
Myofibrillar Hypertrophy vs Sarcoplasmic Hypertrophy Explained in under 5 Minutes. If you want learn more about myofibrillar hypertrophy and sarcoplasmic hypertrophy then this is the video for you. We will look at what they are what are the differences between myofibrillar hypertrophy and sarcoplasmic hypertrophy and how can we stimulate these types of hypertrophy or muscle growth. You can see this as a kind of Myofibrillar hypertrophy versus Sarcoplasmic hypertrophy but really the best of both worlds will be incorporating both by doing low and high rep work. The world hypertrophy means an increase in muscle tissue and many people don't know it gets broken down further into Myofibrillar and sarcoplasmic hypertrophy but I do think its important to know the difference. How we train may have a difference in how we look and how performance in the gym. Some people will highlight the difference between a powerlifting and a bodybuilder and how some in bodybuilding look massive but are not that strong in comparison to their size and some people don't look that big yet are very strong, I think myofibrillar hypertrophy and sarcoplasmic hypertrophy might have something to do with that. This may impact people doing strength training and wondering why they ae getting stronger but not bigger.

A depolarization (action potential) at a neuromuscular junction travels along the muscle cell membrane (sarcolemma) to transverse tubules (T-tubules). From there the depolarization is propagated along the T-tubules and along the sarcoplasmic reticulum, where Ca ion channels open to release the ions. The Ca ions bathe the sarcomeres, permitting the thick and thin filaments to slide and hence, the muscle to contract.

We're kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin. Your smooth, cardiac, and skeletal muscles create movement by contracting and releasing in a process called the sliding filament model. Your skeletal muscles are constructed like a rope made of bundles of protein fibers, and the smallest strands are your actin and myosin myofilaments. It's their use of calcium and ATP that causes the binding and unbinding that makes sarcomeres contract and relax. Pssst... we made flashcards to help you review the content in this episode!

Excitation contraction coupling is a process through which, excitation of muscles is combined with contraction of the muscles. The excitation process is completed with the help of #T-tubules, which is a system of tubules to takes action potential deep inside a muscle fiber. The nerve fibre can activate the muscle fiber membrane, but the T-tubule or transverse tubules takes the impulse deep inside the muscle fiber. Once the impulse reach inside the cell, it activates the #sarcoplasmicreticulum. Sarcoplasmic reticulum has two parts, a cristae and tubules. The cristae of sarcoplasmic reticulum is attached with T-tubule, and it gets excited by the incoming impulse. Once excited, the sarcoplasmic reticulum secrets Alot of calcium ions, the calcium combines with heads of the cross Bridges of the myosin filaments and cause contraction. Once the contraction of actin and myosin filaments has occurred, the calcium ions are taken up again into the sarcoplasmic reticulum. With uptake of calcium the process of excitation contraction coupling comes to an end.
