What Is Fixator Muscles?

The following muscles need to be stretched, lack of flexibility in which group causes the most injuries

In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces 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 (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)

As a result of the contractions in the Muscle- Skeletal Longitudinal Section cells and the Muscle- Skeletal Cross Section cells, it allows your muscle to be able to contract in response to nerve stimuli. This means that the movements of most of these muscles are not involuntary, you can control them. Therefore, once the stimulation stops, the muscles relax.

Biceps Brachii - It's attachments are the coracoid process, supraglenoid tuberosity, and radial tuberosity. When it contracts it causes flexion and supination. It's located close to the endangerment site the antecubital. This area is known for housing chronic pain.

Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example, originates at the chin (geneion) and inserts in the tongue (glossus). Some muscles are named for the arrangement of the fascicle groups. For example the rectus abdominus is the straight muscle that is in the adbominus.

The contraction of the extent which the The direction which the bone of the joint move depends on the contraction of the muscle.

MS are important to coordinate and control muscle contractions, and its purpose is to send a signal to the muscle to contract.

The major muscle groups consist of the upper body, Rotator cuff muscle, Upper arm, Quadriceps, Hamstring group, Lower leg and Midsection. The Upper Body consists of the Trapezious muscle which Orgin is located near the base of skull, occipital protuberance and posterior ligaments of neck. The middle spinous process of 7c and T1 - T3. The lower spinous process of T4-T12. The insertion of the upper Trapezius is located in the posterial aspect of the lateral clavicle. The middle Trapezius is located in the medial border

The process begins while a muscle is relaxed in its resting state. “In the resting state,

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

This arrangement means that muscles are able to work together, allowing for one limb to be straightened by one muscle and to be bent by the other. Muscles that bend a limb are called flexors and muscles that straighten a limb are called extensors.

semitendinosus muscle, figure 1, the muscles extending - except the short head of the biceps - ie between two joints of the hip and knee.

The origin: the muscle is fixed to a bone at the point of the origin. It does not contract at this point.

When sitting muscles involved in posture are voluntary muscle fibres which are known as tonic and twitch fibres. Tonic fibres enable you to remain sitting upright whilst sitting due to the voluntary muscles being in a state of tension. These fibres are red in colour due to large amounts of myoglobin (oxygen-transporting pigment of muscle) and have slow contraction characteristic which means they contract slowly but are able to keep going for long periods in time. Tonic fibres can also be found in large numbers

Origin: the major and minor muscles originate from the spinous processes of C7 and T1 and T2 to T5, respectively.
