FIXATORS are synergists which immobilize the origin of the prime mover so that the prime mover can act more efficiently. For example, the deltoid is the prime mover of arm abduction. The deltoid muscle originates on the scapula, which is a moveable bone. The pectoralis minor, rhomboids, and trapezius muscles attach the scapula to the axial skeleton. When the deltoid contracts to abduct the arm, these other muscles hold the scapula still and therefore act as fixators. http://people.morehead-st.edu/fs/m.mcmurr/231-L11.html this should help you. :) weesa
What else can I help you with?
What muscle ends where Deltoid begins?
The pectoralis major muscle ends where the deltoid muscle begins at the clavicle and scapula. These muscles are important for shoulder movement and stability.
What three muscles of the cat that together correspond to the deltoid muscle of the human?
Cats have three muscles together that correspond to the human deltoid muscle. The muscles are the clavodeltoid, spinodeltoid, and the acromiodeltoid.
What are the 3 muscles used as sites for intramuscular injection?
Intramuscular (IM) injections are typically given in one of three muscles. These muscles are the vastus lateralis, or thigh muscle, the ventrogluteal, or hip muscle, and the deltoid, or upper arm muscle.
How does the deltoid of the cat differ from the deltoid of a human?
The Deltoid in a human is on large muscle and the cat has an upper Clavo Brachialis and a lower Pectoantebrachialis, two muscles instead of one larger one. The Trapezius muscle is one large muscle in humans and in cats is 3 smaller muscles called the Clavobrachialis, Acromiodeltoid, and Spinodeltoid muscles.
Which muscle do not correspond to a human muscle?
When talking about the difference between a human deltoid muscle and a cats deltoid muscle is that in a human it's only one muscle and in cats it is broken into three separate muscles. A cat's deltoid is broken into the clavobrachialis, acromiodeltoid, and the spinideltiod.
What is the function of deltoid ridge?
It is a raised section of the humerus where muscles connect, these muscles are generally used for rotating the arm.
What is the function of the deltoids?
the deltoid has 3 division of fiber, each has its function depending on their location the anterior fiber serves as shoulder flexor, where is the middle fiber for shoulder abduction at frontal plane and the posterior fiber functions as shoulder extensor
What are the four main injection muscles?
The four main intramuscular injection muscles are the deltoid muscle, vastus lateralis muscle, ventrogluteal muscle, and dorsogluteal muscle. While the deltoid muscle site is the upper arm region, the vastus lateralis muscle site is on the thigh. The ventrogluteal muscle is the hip, and the dorsogluteal muscle is situated on the buttock area.
What are some examples of multipennate muscles?
Unipennate lumbricals; Extensor digitorum longus..The triangular deltoid muscle of the shoulder is onethe deltoid muscle is a multipennate not a unipennate, an example of a unipennate is Extensor digitorum longus.
Is the deltoid a skeletal muscle?
The deltoid is an example of skeletal muscle. Some examples of smooth muscle is the muscle lining the GI tract, blood vessels, and the muscles in your eyes that dilate or constrict your pupil. Cardiac muscle is only found in the heart.
What are the pennate muscles of the human body?
Some examples of pennate muscles in the human body include the deltoid muscle in the shoulder, the rectus femoris muscle in the thigh, and the flexor carpi ulnaris muscle in the forearm. These muscles have fibers that run obliquely to the tendon, which allows for greater force generation.
Name the insertion of the primary muscle used?
The primary muscle attached at the point of insertion is the muscle that undergoes the most movement when the muscle contracts. For example, in the bicep curl exercise, the bicep muscle is the primary muscle attached at its point of insertion on the radius bone in the forearm.
