Gross Anatomy of the Muscular System Purpose: What is the purpose of this exercise? The purpose of this exercise is for students to identify and name the major muscles of the human body. Students will also understand the muscle actions correspond with their locations in the body. Are there any safety concerns associated with this exercise? If so‚ list what they are and what precautions should be taken. There are some safety concerns with this exercise. Gloves‚ masks and goggles

Axial muscles are skeletal muscles of the Trunk or Head . 2. The Trapezius is a large superficial muscle that extends from the occipital bone to the lower thoracic vertebrae and to the spine of the scapula. (Include sketch of muscle location in the box provided.) 4. The actions of the trapezius are Its functions are to move the scapulae and support the arm . 5. The Pectoralis major is a fan-shaped muscle on the chest

and strength exercised are essential. After immobilization‚ strengthening is needed to make sure there will be no instability when the athletic/ patient returns to activity.(5) The foundation for all shoulder joint activity is due to a stable scapula. Muscle strengthening exercises to help with scapular control‚ include: scapular depressions (for the trapezius‚ and pectoralis minor)‚ rows (for the rhomboids and middle trapezius)‚ pushups with a plus and scapular punches ( for the serratus anterior)

Pectoral Girdle‚ which is the basis of the shoulder joint‚ is connected to the axial skeleton by the sternoclavicular joint. It also holds the clavicle‚ which is connected to the axial skeleton‚ the scapula‚ which stabilizes the shoulder and the humerus together. However‚ the humerus is also connected to the scapula at the glenohumeral joint‚ which is a ball and socket joint‚ and allows the movement of the shoulder. The humerus is then connected to the humeroulnar and Radiohumeral joints‚ known as the elbow

afflicted arm closely to his body. On further examination‚ the child’s scapula and clavicle had totally dissipated and were no longer there to support the shoulder‚ making his right arm appear to hang lower the left. After the initial inspection of the child an MRI was ordered shown that the reaming scapula had turned into vascularized soft tissue‚ which had not shown up on an x-ray. In this case‚ the disease only effected the scapula and clavicle of the right side of the body‚ and did not affect the
