What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?

The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.


What muscle originates on scapula and proximal humerus and inserts on olecranon process?

The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.


What bone is the semimembranosus connected to?

The semimebranosus is part of the hamstring group and originates at the ischial tuberosity and inserts into the proximal tibia.


Where does the piriformis muscle originate an insert?

The piriformis originates at the anterior sacrum and inserts at the greater trochanter of the femur.


What muscle originates on the distal anterior humerus and inserts onto the coronoid process of the ulna to cause arm reflexion?

The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.


What is the origin and insertion of the gluteus maximus?

Origin: the gluteus maximus originates from the posterior inferior surface of the sacrum and coccyx, and the posterior medial surface of the ilium.Insertion: the gluteus maximus inserts into the gluteal tuberosity on the posterior aspect of the femur, and the anterior aspect of the lateral tibial condyle.


What is the strongest protractor of the scapula?

The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.


Which muscle protracts and depresses the scapula?

The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.


Is it normal to have muscles on your shins?

In human anatomy, the tibialis anterior is a muscle that originates in the upper two-thirds of the lateral surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. Its acts to dorsiflex and invert the foot.


Is the distal attachment of a muscle the origin?

Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.


Moves the scapula forward and downward?

The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.


What bone do the muscles of the rotator cuff originate?

The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
