what is the function of the rhomboid muscle?

Rhomboid major. The rhomboid major muscle is located in the back region and helps keep the scapula, or shoulder blade, attached to the ribcage. It also rotates the scapula and retracts it towards the spinal column.

What is the relationship between muscle function and bones? Muscles use bones as levers to bring about body movements. What are two functions of a bone marrow's cavity? To provide a side for hematopoiesis and a storage site for minerals.

The deltoid muscle is responsible for the brunt of all arm rotation and allows a person to keep carried objects at a safer distance from the body. It is also tasked with stopping dislocation and injury to the humerus when carrying heavy loads.

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.

Function. The action of the anterior and middle scalene muscles is to elevate the first rib, they also flexes and laterally bends the neck to same side. The action of the posterior scalene is to elevate the second rib and tilt the neck to the same side.

The function of occipitofrontalis muscle is to elevate the eyebrows and wrinkle the forehead skin with its frontal part, and to retract the scalp with its occipital part.

Its main function is to bend your forearm toward your upper arm. It also aids in turning your palm up and down. Although a standard pushup doesn't target the biceps muscle, changing the position of your hands can make this muscle play a larger role in the movement.

The muscular system's main function is to allow movement. When muscles contract, they contribute to gross and fine movement.

(Right arm.) In human anatomy, the supinator is a broad muscle in the posterior compartment of the forearm, curved around the upper third of the radius. Its function is to supinate the forearm.

Function. The deltoid muscle (acromial part) is the principal abductor of the arm at the glenohumeral joint. However, it can only do so, when the arm is already abducted beyond fifteen degrees. This initial part of abduction is produced by the supraspinatus muscle.

The infrahyoid muscles are responsible for the positioning of the hyoid bone along with the suprahyoid muscles. They play an active role in swallowing and the movement of the larynx. More specifically, all infrahyoid muscles (except the sternothyroid) depress the hyoid.

The function of skeletal muscle is to contract to move parts of the body closer to the bone that the muscle is attached to. Most skeletal muscles are attached to two bones across a joint, so the muscle serves to move parts of those bones closer to each other.

Rotatores muscles are a set of short muscles located laterally along the vertebral column, attaching between the transverse and spinous processes of thoracic vertebrae. As a result, the rotatores function as stabilizers, extensors and rotators of the spine.

The bones form joints and act as levers, allowing muscles to pull on them to produce movement. The bones of the skeleton provide surfaces for the attachment of muscles.

Function. The primary actions of this muscle include the stabilization, depression, abduction or protraction, internal rotation and downward rotation of the scapula. It elevates the ribs for deep inspiration when the pectoral girdle is fixed or elevated.

The pectoral girdle stabilizes the upper limbs on the thorax and allows a range of mobility at the shoulder. Malformations impair these functions and distort the appearance of the upper chest and back. The pelvic girdle transfers upper body weight to the lower limbs by articulating with the spine.
