Medial rectus muscle

back down to a prone position. In this phase, the same muscles are used as discussed in the pushing up phase, except in the opposite direction. Stabilizers The muscles being discussed are needed to help stabilize the body and keep it straight while doing a push-up. The primary muscles being examined are the abdominal muscles. These muscles are called the rectus abdominis. They are located in the anterior trunk of the midline. This muscle is divided into two sides and is separated by the linea

large muscles, spanning the neck, shoulders and back. CLAVICLE – Clavicular Pectoralis Major Also commonly known as the collar bone, the clavicle is the only long bone in the body that is horizontal, connecting scapula to sternum. Because of its position, the clavicular pectoralis major is commonly referred to as the “upper chest”. CRANIUM – Trapezius (upper) Made of flat bones, along with the mandible it forms the skull. The upper trapezius helps stabilize the head and neck. FEMUR – Rectus Femoris

types of muscles used while bumping a volleyball such as the shoulder, elbow, and knee muscles. The joint used in the shoulder muscle is the shoulder girdle and the action you can do is elevation. When bumping a volleyball, the agonist muscles used are the upper trapezius, rhomboids, and levator scapulae. While the antagonist muscles are latissimus dorsi, pectoralis major and minor, serratus anterior, and trapezius. The bones used are the humerus, scapula, and clavicle. The deep muscle group that

Stewart, 2016). The nerve consists of two different motor fibers: the somatic motor component and the parasympathetic motor component. The somatic motor component controls the movement of four extrinsic muscles and the parasympathetic motor component controls the sphincter pupillae and ciliary muscles (McKinley, O'Loughlin, & Bidle, 2017, p. 44). CN III can be divided into two major branches: the superior division and inferior division (Jaffee & Stewart, 2016). The superior branch is composed of motor

fluid to reduce friction. Each bone in a synovial joint has articular cartilage at the articulating surface. The C-shaped medial and lateral menisci serve to deepen the articulation at the superior surface of the tibia, thus enhancing the bony stability of the joint. Also

Just above at the ankle, the junction must be able to perform dorsal flexion for a strong plié that will allow the body to keep turning. Higher up, the quadriceps femoris muscles provide the strength to perform continuous grands ronds des jambes en l’airs. A developpé devant is held up only with the flexion of this muscle. As the leg carries to à la secondé, followed by a sturdy passé, the quadricep holds strong. This allows the body to turn

also receptors in your muscles and tendons help your body to balance. The receptors in your muscles and tendons are called proprio receptors, these proprio receptors detect how stretched your joints, tendons and muscles are. Secondly it allows movement as muscles cross joints and attach bone to bone. Muscles work in pairs and skeletal muscles can pull in one direction and for this reason they always come in pairs. Due to the fact that two muscles work together, as one muscle in the pair contracts

Jeon-Min Hwang and associates found that the absence of the CHN1 caused the subsequent absence of cranial nerves IV and VI (18). Cranial nerve four, also known as the trochlear nerves, serves to lower the eye as it is adducted by the superior oblique muscles; in
