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.
Name the depression on the ulna into which the humerus inserts?
The depression on the ulna into which the humerus inserts is called the trochlear notch. This forms the hinge joint known as the elbow joint.
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 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 large broad sheet of muscle that originates along the thoracic and lumbar vertebrae and inserts upon the humerus?
The large broad sheet of muscle you are referring to is the latissimus dorsi. It is responsible for movements like shoulder extension, adduction, and medial rotation of the arm.
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 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 muscle originates from the anterior inferior iliac spine of the hip and inserts onto the proximal end of the tibia?
The muscle that originates from the anterior inferior iliac spine of the hip and inserts onto the proximal end of the tibia is the sartorius muscle. This muscle is the longest muscle in the body and is responsible for flexing, abducting, and laterally rotating the hip joint, as well as flexing the knee joint.
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.
What muscle flexes the elbow but neither originates nor inserts on the humerus?
The biceps brachii muscle.
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 is the large broad sheet of muscle that originates along the thoracic and lumbar vertebra and inserts upon the humerus?
Latissimus dorsi
What large muscle originates along the sternum and inserts onto the humerus?
You have the pectoralis major muscle in the chest wall. It arise from the sternum and the clavicle. It is inserted on the lateral part of the bicipital groove.
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.
What is the depression on the ulna into which the humerus inserts?
olecranon fossa
What muscle inserts on the greater tubercle of humerus?
supraspinatus
