longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral

The Deltoid Muscle The deltoid muscle is in the shoulder area, towards the proximal end of the arm. The muscle itself is rounded and triangular in shape, and consists of three main “heads” or muscles fibre strands; the lateral, anterior, and posterior deltoids. It is used for arm extension in all angles and rotation, mainly up and down straight out to the side. The deltoid has three main functions that involve the three individual muscle “strands”. The the anterior deltoid rotates the humerus anteriorly

Acceleration The acceleration phase, takes place from maximal shoulder external rotation until the release of the football with shoulder internal rotation. The non-dominant elbow during the acceleration phases is ripping back. Like a young child ripping their favorite toy away from someone. The non-dominant hand should end up near the non-dominant armpit. The height of the dominant elbow should be maintained above the dominant shoulder with a slight flexion in the elbow. The ‘Little C’ should be

surgical and clinical settings in this specialty, I became fascinated with the diagnosis and treatment of deformities or functional impairments to the movement systems of the body, primarily the skeletal system and its associated structures such as muscles and ligaments. Kinesiology is defined as the study of the principles of anatomy, physiology, and mechanics in relation to human movement. Therefore, orthopedic doctors often diagnose and treat injuries that can be explained by principles of kinesiology

Introduction The goal of this lab was to dissect and isolate the muscles and organs of a cat. Dissection is the act of cutting into a specimen to learn the anatomy of it upon other things. Isolation is the act of separating one body part from another. The groups were to explore different areas of the cat as a class. After observing for six days the students were to know the locations of muscles and organs throughout the specimen. The anatomy of a cat is very similar to a human so it was a perfect

causes of poor posture are muscle tightness and muscle weakness, therefore it is important to design a stretching program to improve muscle length, as well as a resistance training program to improve strength. Prior to commencing exercise our patient is to complete a warm up consisting of low intensity exercise (approximately 40% of heart rate max), for between 7 and 10 minutes, this is followed by a series of dynamic stretching exercises aimed at preparing the muscles for physical activity, improving

First Muscles perform three types of contractions: concentric, eccentric, and isometric. When executing a strength exercise, all three of the muscle contractions are involved. As you perform a movement, the main muscles undergo a concentric contraction while the opposite muscles undergo an eccentric contraction. The adjacent parts of the body that are not in use are stabilized via the isometric contraction. • The strongest phase is during the eccentric contraction which controlling and stopping

3. While performing the off-centre attitude in parallel different groups of muscles contract to produce movement needed to execute this balance. Beginning from the lower half of the body there are primary muscles that contract to produce dorsiflexion of the calcaneus: the tibialis anterior and pernoneous tertius are the agonists and the peroneous longus and peroneous brevis are the antagonists of this action. Although, when dorsiflexion reverses to plantaflexion the roles of agonist and antagonist

Rick Winstead Steve Hammons PTA 150 2/13/15 Brachial Plexus At first glance, the brachial plexus may be a bit intimidating. The nerves arising from it and the muscles of the trunk and upper extremity of which it innervates may seem overwhelming, but as one begins the process of adding all of the components together in an orderly fashion, it begins to be seen in a much more easily understood manner. The first step in this process is to gain a grasp on the basic main structure of the plexus, and

tightnesses in the muscles of the upper and lower regions of the body. By using this method it enables the therapists to predict patterns of weaknesses and tightnesses in the muscular tone, thus creating imbalances in the muscular system and further causing dysfunction in the body's movements. Upper cross syndrome: The facilitated muscles of the upper region of the body are: Upper trapezius fibres, levator scapula, sternocleidomastoid, anterior scalenes and the pectoralis major and minor. The inhibited
