FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

Muscles are all made of the same materials‚ a type of flexile tissue of thousands narrow tissues that make up all the muscles. There are three types of muscle tissue in the human body which are Cardiac‚ Smooth and Skeletal Muscles. Cardiac Muscles are muscles that conduct‚ forced‚ being completely in heart‚ responsible for pumping activity of heart‚ very heavy and solid. Smooth are non band‚ not under voluntary force found in comfortable organs of body accountable for growth like absorption of food

How to Build Muscle 1. Develop a Technique Learn the proper way to do each exercise whether it is pushups or weight training. Developing a solid technique will maximize the workout and strengthen the muscles. Strength training is a method that should not be overlooked because it allows a person to start with minimal weight and add more weight as they progress. This builds more muscle which in turn builds more strength. 2. Machines vs. Free Weights Those weightlifting machines

by the nervous and endocrine systems Skeletal muscle tissue function of most is to move bones of the skeleton (are few that attach to other structures ex--the skin). Muscle tissue is striated b/c alternating light and dark protein bands (striations) are visible when tissue is closer examined. Muscle tissue action is voluntarily/activity can be controlled consciously. Cardiac muscle tissue found only in the heart—forms most of the heart wall. Muscle is striated (like skeletal)‚ and its action is

Muscle contractions happen when muscle fibers are stimulated‚ which can cause one of many types of contractions. Isometric contractions‚ which means that tension happens in the muscle but there is no change in muscle length‚ therefore there is no movement of the muscle itself. An example of Isometric contractions would be strength training‚ such as holding a weight still‚ which happens in the biceps brachii. The biceps brachii the gets more tension‚ but the muscle length stays the same. As for isotonic

When trying to reach your muscle growth goals‚ it is important that you have a customized body building workouts that are meant for you. What it means is that you have to take into consideration of your body type and genes‚ and how your metabolism rate is like when determining your workout routine as well as your muscle building diet. Following blindly without being able to improvise and improve will be as effective as compared to body building workouts just for you. One common mistake that most

Muscle Cars: Past and Present There have been many different car designs throughout the years but none as popular as the muscle cars of the 1960’s. The 1960’s was a golden era for American automakers with the creation of the vintage iron. With that era long gone‚ the automakers were driven to recreate visions of the past. The 1960’s muscle car is the inspiration to the newly resurrected models of 2010 with great style and performance. Muscle cars are an American icon‚ and it still holds true with
