Hip flexion/ Knee Extension; Hip extension/ Knee flexion. Major muscles involved include the quadriceps, the inner thigh, the hamstrings and gluteal region. Also, leg strength in the calve muscles is important.

As explained by Opar (3) the hamstring consists of three muscles, biceps femoris (BF), semitendinosus (ST) semimembranosus (SM), this composes a muscle group crossing the hip and knee joint that acts synergistically in extending the hip and flexing the knee.

The longest muscle in the human body is the Sartorius (purported sar-TOR-ee-us). It runs starting from the waist over the front of thigh to the knee. Its design is to flex the hip and knee. The biggest muscle in the body is the gluteus Maximus (professed GLUE-tee-us MAX-si-mus; bottom muscles). It moves the thighbone far from the body and straightens out the hip joint. Skeletal muscles are presumably the most well-known kind of muscle. They are the muscles that throb after strenuous work or activity. Skeletal muscles make up around 40 percent of the body's mass or weight. They balance out joints, help look after carriage, and give the body its general shape. They likewise utilize a lot of oxygen and supplements from the blood supply. Skeletal muscles are appended to bones by extreme, stringy connective tissue called tendons. Tendons are rich in the protein collagen, which is masterminded in a wavy manner so it can extend and give extra length at the muscle-bone

These muscles begin at the ischial tuberosity, which is at the bottom of the pelvis. The muscles meet at the knee joint and end at the lower leg, where they are joined together through connective tissue that attach the tendons to the bones like double-sided tape. The hamstring muscle groups work to help extend the leg back and provide motion at the knee. Due to the crossing

With regards to the lower back, the hamstring muscles are attached to the bottom of the pelvis, in a similar area to the bony points of your buttock you sit

vastus medialis. Collectively the quadriceps muscle is the biggest in the human body and its purpose is to expand the knee. The specific task of the vastus lateralis muscle is to extend the lower leg and allow the body to rise up from a squatting position.(Hannan et al, 2000).

Hip flexors (Psoas major, rectus femoris, sartorius, tensor fasciae latae, pectineus, adductor longus, adductor brevis, gracilis)

The iliopsoas is actually two muscles, the psoas major and the iliacus. They originate in different areas, but come together to form a tendon, hence why they are commonly referred to as one muscle. Unlike many of the anterior thigh muscles, the iliopsoas does not extend the leg at the knee joint.The psoas major originates from the lumbar vertebrae, and the iliacus originates from the iliac fossa of the pelvis. They insert together onto the lesser trochanter of the femur.The iliopsoas flexes the lower limb at the hip joint and assists in lateral rotation at the hip joint.The psoas major is innervated by anterior rami of L1-3, while the iliacus is innervated by the femoral nerve.The quadriceps femoris consists of four individual muscles; three

Two other muscles have origin above the knee. The gastrocnemius muscle is a rather large muscle that has two heads of origin above the knee. The medial head originates just above the posterior medial condyle of the femur. The lateral head has its origin on the posterior lateral surface of the lateral condyle of the femur. These two heads come together to form a large muscle that

The quads include the rectus femoris, and the vastus lateralis, intermedius, and medialis. This muscle group shares a common tendon at insertion. The patellar tendon inserts at the tibial tuberosity, and within this tendon lies the patella. The patella is anterior to the femur-tibia articulation, and this sesmoid bone increases the leverage of the quads by acting as a pulley. The major contributor to the stability of the knee joint is the strength of the quads. The only muscle that assists in extension is the tensor fascia lata.

is the back portion muscle of the lower leg. The muscle group’s structure consists of two main muscles (Gastrocnemius and Soleus).

A couple of muscle groups associated with the gluteus are the gluteus maximus, and the gluteus minimus. Exercises for the gluteus maximus would be squats while exercises that would isolate the minimus would be leg lifts with resistance bands. My experience with both of these were great. While and after doing squats you could really feel the the muscles being workedout from it while doing the leg lifts had a drifferent sensation. The leg lifts with the resistance band felt like I was hitting a whole new muscle because while preforming this exercise the resistance band really helped isolate the gluteus minimus. The next set of muscles are the abdominals. The origin is the superior surface of the pubis around the symphysis and the insertion is the inferior surfaces of the costal cartilages. The workout chosen for this muscle group was the sit up. While preforming the exercise at a slow speed (4 sec from point to point) you can really feel the resistance placed upon your abdominals in a wide range this workout was excellent for this muscle group and I highly recommend it for most clients as long as it is within their parameters.

A cow has many different muscles throughout its skeletal system. The Masseter is a muscle in the cheek that helps the cow with chewing and biting. The Trapezus is a triangular muscle that helps move the front appendages. The appendages is the legs or something that sticks out and needs help moving. The Latisimus dorsi is a long muscle that attaches the humerus bone to the forearm. The abdominal obliques are large muscles that run along its side and aid in supporting the organs used in digestion and reproduction. The gluteals are located in the upper backside region, and it helps with real leg movement. Biceps Femorous is a muscle is found in the rear leg of the cow. The Biceps Brachii helps to allow the cow to flex its front legs.The Triceps

Next, Matt has to push up using all of his strength. Muscle used in this process are the Hamstrings which flex the knee for movement, the soleus, which provides power to the ankle, and the Tibilias anterior, which inverts the ankle. Now, Matt is finally in standing position. In this position, Matt is using his Gluteus Maximus, one of the strongest muscles in the human body, and this allows for movement of the hip & thigh. Also, Matt is using his Hamstrings, Soleus, and Tibilas anterior, which very also used in other positions in the process of standing from sitting position. With all of the different muscles used in this process of standing from sitting position, there were also various nerves that inverted these muscles. For the Quadriceps it would be the femoral nerve, the Fibularis Longus with the Peroneus longus nerve, the Latissimus Dorsi with the Thoracodorsal nerve, the Gluteus medius which uses the superior gluteal nerve, and the gluteus maximus which uses the inferior gluteal nerve, the Internal oblique which uses the both the iliohypogastric nerve and the ilioinguinal nerve. Also, the Trapezius which uses

The muscles in the abdomen are just like other muscles in the body, they are required to work out but at regular intervals like 2-3 non repetitive days a week. These abdominal exercises affect the lower upper and oblique abdominal muscles. These ab exercises help you to get a flatter tummy.
