Gluteals are the group of muscles comprising of your buttocks. Out the four muscles in your buttocks‚ there are only 3 groups of muscle that can be found on your buttocks. These muscles are gluteus maximus‚ medius and minimus. The fourth group which is the smallest one is the tenor fasciae latae muscles that can be found in the anterior area of the body. Functioning together‚ the gluteal muscles handle most of the motions of the upper leg‚ which includes rotation of the thigh‚ and abduction and turning

The two main processes involved in muscle contraction are cross-bridge cycling and the length-tension relationship‚ which normally function to maximize contraction in the muscle. Beginning with the activation of a motor unit‚ the ions flow from the motor unit towards the muscle fibers that it innervates by the motor neuron in the same way as a normal muscle would. However since the tissue is damaged‚ the force that is generated by these muscle fibers will not be as great‚ leaving the fibers less

Advance Preparation—ATP Muscle Kit 1. Order the ATP muscle kits (Carolina) to be delivered no more than seven days before the lab. One kit provides generously for eight students. Extra vials of the chemical solutions can be ordered separately (Carolina) and will reduce waiting time. Just before the lab begins‚ cut the muscle bundles into 2-centimeter lengths and place in a petri dish in the accompanying glycerol. 64 Exercise 11 R E V I E W S H E E T NAME ____________________________________

Muscle In this experiment‚ you will explore how muscles work. You will also examine some of the properties of muscle fatigue. In this experiment‚ you will electrically stimulate the nerves in the forearm to demonstrate recruitment‚ summation‚ and tetanus. Written by staff of ADInstruments. Background The skeleton provides support and articulation for the body. Bones act as support structures and joints function as pivot points. Skeletal‚ or striated‚ muscles are connected to the bones

Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

We have three types of muscles in our bodies‚ skeletal‚ smooth and cardiac. Each type of muscle performs different functions in our bodies. Some of the characteristics of our muscles are that they respond to stimuli‚ they are able to shorten in length‚ they stretch when they are pulled and they tend to return to their original shape after contracting or extending them. Muscle contractions occur when our nervous system sends a signal via the neuromuscular junctions the signal arrives at the end bulb
