What muscle agonists antagonists and assisters are involved in shoulder extension and flexion?
The muscles located in the shoulder and move the arm are: the deltoid, teres major, and rotator cuff muscles. The deltoid muscle is like three muscles in one: the anterior fibers flex the shoulder, the lateral fibers abduct the arm, and the posterior fibers extend the shoulder. The rotator cuff muscles are the supraspinatus , infraspinatus , teres minor, and subscapularis . They can be remembered with the mnemonic SITS. The primary function of the rotator cuff muscles is holding the head of the humerus in the glenoid cavity. They act more to assist the other muscles.
What are muscles cells called?
Muscle fibres
What is the role of the spindle fibers?
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.
What organ is made of bundles of fibers?
Muscles are organs that are made up of bundles of fibers. These fibers are responsible for producing movement in the body by contracting and relaxing.
How are muscle fibers arranged to form a muscle?
Muscle fibers can be arranged into two basic structural patterns, fusiform and pinnate. Most human muscles are fusiform, with the fibers largely arranged parallel along the muscle's longitudinal axis. In many of the larger muscles the fibers are inserted obliquely into the tendon, and this arrangement resembles a feather. The fibers in a pinnate (feather) muscle are shorter than those of a fusiform muscle. The arrangement of pinnate muscle fibers can be single or double, as in muscles of the forearm, or multipinnate, as in the gluteus maximus or deltoid.

What is the fiber direction of a cats internal oblique muscles?
The cat's muscle fibers run perpendicular to its internal oblique muscles. The fibers of the external oblique muscles run opposite of the muscles.
What is the most muscles contain?
fibers
What do the middle fibers of the deltoid muscles do?
The middle fibers of the deltoid abduct the arm.
What are muscles?
Muscles are tissues composed of fibers, the contraction of which produces movement in the body.
Why are muscles called fibers?
muscles are called fibres cuz they have alot of fibre in them
Are there fast twitch muscles in your legs?
There are fast twitch muscles fibers in all of your muscles, especially in your legs.
Are muscles made of little fibers?
Yes, muscles are made up of muscle fibers. If you want to know more about muscles go to this site: http://kidshealth.org/teen/your_body/body_basics/bones_muscles_joints.html#
Which of these is not a way of classifying muscles?
the type of muscle fibers
Do muscles fibers stretch during contraction?
No, they contract.
What are muscles cells called?
Muscle fibres
What happen when muscles shorten?
What happens when a muscle shortens is that it is contracting. This is when the fibers of the muscles generate tension.
