what is the function of the axial muscles (module 10.4a)?

transversus. Axial muscles position the head and spinal column and also move the rib cage for breathing.

The anterior axial muscle that crosses the glenohumeral joint is the pectoralis major muscle.

Function. Gluteus maximus main actions are to extend and laterally rotate the hip joint. Furthermore, upper fibers can abduct the hip whereas the lower fibers can adduct.

Axial/Abaxial: Axial -- directed toward the longitudinal central axis of a limb. Abaxial -- directed away from the longitudinal central axis of a limb.

The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles. In humans an additional function is to transmit body weight in walking and standing.

The muscular system's main function is to allow movement. When muscles contract, they contribute to gross and fine movement. Gross movement refers to large, coordinated motions and includes: walking.

Axial load. Axial loads are applied along the longitudinal or centroidal axis of a structural member. If the action of the load is to increase the length of the member, the member is said to be in tension (Fig. 3.1(a)) and the applied load is tensile.

['Support : It provides a framework to support the organs and tissues of the body.', 'Protection: It protects our internal organs. ... ', 'Movement: It provides a framework for muscles to attach.']

Axial Force is generally defined as the Force acting along the axis of the component / assembly. For example consider a cylindrical Building column/ Square column. ... Every truss element of the structure is designed to take only Axial forces (Either Tension or Compression).

The axial muscles include the muscles of the tail, trunk, and eyeballs as well as a group of muscles called hypobranchial muscles, which separate and migrate from the others during development.

The main function of this chest muscle as a whole is the adduction and internal rotation of the arm on the shoulder joint. Acting independently, the clavicular part helps to flex the extended arm up to 90°, while the sternocostal part facilitates the extension of the flexed arm by pulling it downwards.

The vestibulospinal tract is comprised of a lateral and medial pathway. The function of these tracts is to maintain equilibratory reflexes from the input of the vestibular apparatus. They will reach the axial muscles, i.e. intercostal and back muscles, as well as the extensors of the limbs.
739229
The multifidus muscle is an important stabilizer of the lumbar spine. It functions together with transversus abdominis and pelvic floor muscles for spine stability.
1043668
Axial force is the compression or tension force acting in a member. If the axial force acts through the centroid of the member it is called concentric loading.
1027144
The function of the pectoralis major is different for its different heads. The clavicular head flexes the humerus, and the sternocostal head adducts the humerus. As a whole the action is to adduct and medially rotate the humerus. It also draws the scapula anteriorly and inferiorly.

Benefits: An effective exercise for recruiting the rectus abdominis muscle and increasing its general strength. Functional anatomy: The curl-up involves flexion of the thoracic portion of the spine to lift the weight of the shoulders and head off the floor, using the rectus abdominis assisted by the obliques.

The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. It consists of the skull, vertebral column (including the sacrum and coccyx), and the thoracic cage, formed by the ribs and sternum. The appendicular skeleton is made up of all bones of the upper and lower limbs.
