The whole human body in respect to bones, bony landmarks, muscles, and their actions are connected. Whenever there is a movement, the different parts of the human body moves as one. In general, knowing the importance of the connecting and applying the information can help understand where the injury or soreness of the body is located. In the any allied health profession, understanding how the human body is connected is also very important. This may help understand the pathology and potential treatment of the patient.
Applications/ Example:
For example when lifting the arm out in front of body and up overhead also known as shoulder flexion, there are many muscles, joints, and bones used for the action. The pectoralis major flexes the shoulder.

The long head of the biceps muscle assists other muscles with flexion. The long head origin is at supraglenoid tubercle of the scapula and its insertion is at the tuberosity of the radius and aponeurosis of the biceps brachii. The coracobrachialis is a small muscle that helps in flexing the shoulder. It originates from the coracoid process of the scapula and inserts in the medial surface of the mid-humerus shaft. The teres major and subscapularis muscles assist with other muscles to flex the shoulder. The teres major originates on the inferior angle and lower one-third of lateral border of the scapula while it inserts at the crest of the lesser tubercle of the humerus. The subcapularis originates at the subscapular fossa of the scapula and inserts at the lesser tubercle of the …show more content…
Also using MRI can determine if there is a tear in the tendon.
Another example that uses many body parts is walking. The gastrocnemius and soleus are major muscles in walking. . The gastrocnemius origin is on the condyles of the femur and its insertion is on the calcaneus through the tendon, while the soleus muscle the insertion is the same as gastrocnemius, but its origin is on the posterior surface of the tibia and posterior aspect of head of fibula.
Two minor muscles in walking are the tibialis anterior and tibialis posterior. The tibialis anterior inverts the foot and dorsiflex the ankle. Its origin is on the lateral condyle of the tibia and the insertion is on the medial cuneiform and base of the first metatarsal. The tibialis posterior inverts the foot but plantar flex the ankle. Its origin is on the proximal posterior shafts of the tibia and fibula, while it s insertion is on all five tarsal bones and bases of the some of the
The gluteus maximus originates from both the ilium and the sacrum and inserts on the femur. The gluteus minimus abducts and rotates the thigh outward. The biceps femoris originates from the tuberosity of the ischium and is responsible for abducting the thigh and flexing the hindlimb or in humans the thigh/leg. The gastrognemius originates from the lateral sesamoid bone of the femur and extends the hindfoot in minks and the calves in humans (Scott).
The ability to flex the finger consists of a serial of flexor muscles in the forearm and their tendons are inserted to the bones of finger. The injury of flexor tendon might cause the loss of bending of the fingers or thumb. The flexor digitorum profundus tendon (FDP) attaching to the distal phalanx and the flexor digitorum superficialis tendon banding to middle phalanx well demonstrated the specific type of tendon-to-bone insertion site characterized by the four-zone enthesis.[1] The retinacula (sheath) structures serve as strong fibrous bands wrap around the flexor tendons in order to keep the flexor tendons in place while flexion.
One major injury suffered in the shoulder is to the rotator cuff. The rotator cuff is a group of muscles and its surrounding tendon in the shoulder. These muscles and tendons (rotator cuff) serve to stabilize the shoulder. Many athletes are at risk of injuring the rotator cuff through repetitive impact and sudden movements.
A rotator cuff is simply a group of four tendons and muscles that are located right on the shoulder and on top of the humerus bone. (Source 1) The rotator cuff is what controls the shoulder and allows it to move and be mobile. The four main muscles that consist of the tendons are the supraspinatus, infraspinatus, teres minor, and subscapularis muscles. (Source 2). Too much wear and tear on these muscles (such as too many thrown fastballs) is precisely what causes the rotator cuff to begin to tear, as well as swelling in the tendons.
Kinesiology can be defined as the study of mechanics of body movements, so I think that is very important to know the meaning of movement when studying kinesiology. Everything in kinesiology has to do with the movement. Every action the body takes is a movement which is what kinesiology is. You cannot be successful in the field of kinesiology no matter what you are doing if you do not understand what movement is. It is the study of human movement, performance, and function by applying the sciences of biomechanics, anatomy, physiology, and neuroscience. It looks at movement and which muscles are involved to create movement relating to strength exercising and sports technique. Movement is an act of changing physical location or position or of
Joints which include rotation is the shoulder joint and the hip joint, this allows us to move the bones connecting to that joint in a wide range of directions. This type of rotation can also be broken down into two types of rotation: medial and lateral (internal and external). Ball and socket, condyloid and plane joints allow this type of movement. Internal rotation of the arm is when the arm is flexed but it moves towards the centre (midline) of the body. However external rotation of the arm is when the arm is flexed, but it moves away from the midline of the
“The doctor of the future will give no medication, but will interest his patients in the care of the human frame, diet and in the cause and prevention of disease” by Thomas A. Edison. Chiropractors use hands-on spinal manipulation and other alternative treatments on the spine which will enable the body to heal itself without surgery or medication. Chiropractic care began in 1895 when its founder, Daniel David Palmer, claimed any and all diseases could be healed by nothing more than just his hands. Dr. Palmer examined a janitor who was deaf for 17 years after the janitor felt his back was out of place, so Dr. Palmer gave an adjustment to what was felt to be a misplaced vertebra in the upper back. The janitor then observed that his hearing improved thanks to Dr. Palmer. Chiropractors use manipulation to restore mobility to joints restricted by tissue injury caused by sitting without proper back support. Chiropractic is primarily used as a pain relief alternative for muscles, joints, bones, and connective tissue, such as cartilage, ligaments, and tendons. About 22 million Americans visit chiropractors annually
One of the functions of the rotator cuff muscles and the long head of the biceps, is to pull the head of the humerus down from the acromion process, to prevent impingement. Strengthening the subscapularis, infraspinatus and teres minor can help with this function. Dr. Fishman discovered a technique when doing yoga and experienced relief of his own rotator cuff pain. The technique is based on a headstand in yoga and is called the Triangular Forearm Support.
In organisms, there are three types of muscle. Smooth muscle helps make up the internal workings of our systems, while cardiac muscle builds our heart, supplying us with oxygen through the blood. The third type of muscle, skeletal, is important for locomotion. It attaches bones to bones, joints to joints, and allows movement. Skeletal muscles differ from one part of the body to another. This is due to the fact that we need to use our bodies for different things. While we may need to move our legs at great length, our fingers might not be able to take the same charge.

The soleus, gastrocnemius and tibialis anterior contract isometrically to keep the ankle stable at 90 degrees (Teachpe.com n.d.) (The previous reference identified was used to identify key joint types and muscles throughout my analysis).
Although the external and internal oblique muscles rely on each other to produce movement, they also serve individual purposes.
When performing manual muscle testing for shoulder flexion and abduction, PTA’s typically place their hand at the wrist verses the mid-extremity because placing their hands at the wrist increases the length of the lever thus testing the muscles ability to resist externally applied force overtime and across the bone-joint lever arm system. Shorter lever arms will provide higher testing scores when compared to using longer lever arms, thus changing the point of force application affects the length of the lever arm and therefore the muscle torque.
Skeletal muscle is a muscle that is connected at either one or both extremities of the skeleton to form part of the mechanical system that moves the limbs and other parts of the body. The human body contains more than six hundred skeletal muscles, which establish forty percent to fifty percent of the total body weight. Nevertheless, skeletal muscle performs three important functions which include: force generation for locomotion and breathing, force generation for postural support, and heat production during cold stress. The most obvious function of skeletal muscle is to enable an individual to move freely and breathe. Skeletal muscles are attached to bones by tough connective tissue called tendons. Muscles that decrease joint angles are called
The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
Also, there are two types of muscle. One is voluntary, in which they move when he or she desires. Muscles such as the ones in the arms and legs are voluntary muscles. The second type is involuntary, meaning they are automatically moving by hormones and the nervous system. They are muscles located in the heart, intestines, stomach, and other organs. The muscular system is quite a valuable system because it allows people to move and support weight. The muscular system consists of three types of certain muscle which are the following: skeletal muscles, smooth muscles, and cardiac muscles. The skeletal muscles help allow the body to move. The smooth muscles are encapsulated in organs, such as the intestines and the stomach and are involuntary. Cardiac muscles are only found within the heart and it is also involuntary (Rettner; Your Body’s
