The hip flexor contains seven main muscles, two of the muscles are Iliacus and the Psoas Major (found in the abdomen). They are more commonly referred as the Iliopsoas. The Iliacus operates on the pelvic crest and goes all the way to the femur. The third main muscle is the Sartorius goes down the thigh in the anterior compartment. Four out of seven is the Vastus Rectus or the Rectus Femoris, is one of the four quadriceps muscles of the human body.…
It is the largest part of the thigh. The fibres run in a 12-15 degrees lateral direction to the Femur. If it has extreme tightness, it can cause real pain and discomfort because it may push the Patella out of place. Vastus Intermedialis: its Fibers run nearly in a directly vertical line and contribute to the full extension of the knee. Due to this, it is the hardest muscle out of the four to extend even further after the knee is fully extended, it cannot be further stretched by hip extension.…
There are three types of muscles in the human body: cardiac muscle, smooth muscle and skeletal muscle. For the purpose of our lab we will be focusing only on skeletal muscle. Skeletal muscle is the only voluntary muscle tissue found in the human body. They're attached to bones by tendons and are responsible for all the movements that are consciously controlled such as writing, walking, running, etc. [1].…
Calf strains are a very well known problem for runners, soccer and basketball players, gymnasts, and dancers, and even more common in athletes who are advancing in age. The calf muscle consists of nine different muscles; the gastrocnemius, soleus, and plantaris muscles attach onto the heel bone and they all work together to produce the upward and downward motion of the foot (calf raise). The other six muscles cause knee, toe, and foot movements in different directions, however those muscles are not relevant to this particular study. The muscle we focused on was the gastrocnemius muscle during a calf raise. A calf muscle strain is graded according to the amount of muscle damage that has occurred: Grade 1 is mild or partial tearing of a few muscle…
The insertion is at the lesser trochanter. The illiacus origin is the iliac fossa and the insertion is at the lesser trochanter. These muscles flex the trunk toward the thigh. The muscles that are relaxed during the movement of the trunk flexion are longissimus, illiocostalis, multifidi, rotatores, semispinalis capitis, spinalis, interspinalis, and intertransversarii. Multifidi, rotatores, semispinalis capitis, interspinalis, and intertransversarii were mentioned earlier in this analysis.…
1. The Jendrassik maneuver played a major role on the patellar reflex. One of the prevailing hypotheses has to deal with the alpha-gamma co-activation theory. It states that the alpha motor neurons activates the motor tone, which leads to the spindles providing feedback to the brain. This process is done by the gamma motor neurons, who are in charge of controlling the stimulation of the cerebellum.…
1. The figure in the question shows the motor and sensory topographic organization through the use of a homunculus. The homunculus in the motor system figure is correct in both pathways due its somatosensory nature. There is evidence though that while this map technically is correct in broad terms, the M1 somatotopic map is much more complex and non-linear then this. It was originally thought that the motor system had sequential operations that were encoded at each step by a different neuronal population and its only role was that of which muscles to contract, when, and with how much effort.…
Psychology Lab Research Question: Why do older adults show a decrease on postural control? Hypothesis: Older adults with decreased knee or ankle threshold joint position sensation would show decreased postural control. • Threshold joint position is a test of sensory sensitivity used to quantify each subject’s proprioceptive abilities Methods: • 22 women and men, 70 yoa or older • all subjects had threshold joint position testing at ankle (plantar and dorsiflexion) and knee joints (flexion and extension) - Subjects were told to press a stop button the moment they detected movement in the joint - performance was measured in degree of joint rotation that occurred prior to their sensing movement - This data was used to categorize subjects…
Muscles involved in PFPS consist of overall hip and leg muscles, mainly the vastus lateralis and vastus medialis. Tendons involved comprise of tendons and ligaments that surround and stabilise the knee with emphasis on the quadriceps tendon, patella tendon, patella retinaculum and iliotibial band. Bones involved start from the hip till the feet with emphasis on the patella, femur, tibia and patellofemoral joint, which encompasses the trochlear groove and femoral condyles.…
The text was primarily intended for engineering students in their sophomore or senior years in college who have a strong mathematical background and are interested in pursuing an engineering degree. Students that are in the natural sciences or health professions also use this source for practice if they possess the appropriate mathematical skills. It also presents information about biomedical systems and biomedical technologies. Enderle…
Introduction Some people believe that we have only one type of muscle in our bodies that help us with all different types of tasks, however; not only do our bodies have different muscle types, they also contain different muscle fibers that are used for different activities. Skeletal muscle contain three types of muscle fibers: slow twitch, fast twitch oxidative, and fast twitch glycolytic. Most muscles in our bodies have different combinations of these muscle fibers, although our body recruits different muscle fibers for different activities. The first muscle fiber to be recruited are slow twitch fibers, are also known as Type I. “Slow twitch muscle fibers are the smallest in diameter, contain the least amount of actin and myosin, and allow…
INTRODUCTION The proteins actin and myosin is the caused of excitement of skeletal muscle. It can be made chemical, electrical and mechanic. When the muscles are use many times to the maximum force, the muscle will decline. That decline is called muscle fatigue.…
Tennis Serve Analysis The all important tennis serve; people say it’s the hardest part in tennis; that the server wins the point and so people need to know how to do it well. In this presentation I will compare and contrast my tennis serve with a professional to highlight my weaknesses and to provide recommendations through different types of practice and feedback to improve my serve. The major weakness in my tennis serve is the incorrect balance of weight in the prep phase, no snap of the wrist in the impact phase, no follow through motion in the recovery phase and an inconsistent ball toss. To improve on my serve I will use different types of practice relative to my flaws and feedback.…
More specifically, the muscles of the leg that are developed…
Using a non-causal filter from G_F=G^(-1)/G_filter (2.65), might solve the problem. As the transfer function of mathematical model is in first order, the transfer function of filter can be chosen such that:…
