Exam 11: A: Anatomy of the Muscular System

If one of the sternocleidomastoid muscles contracts,it causes a different movement than if both of them contract.

The occipitofrontalis muscle is actually three muscles.

Tendons anchor muscles to bone by attaching to the periosteum of the bone.

No muscles are both muscles of facial expression and muscles of mastication.

Both the interspinales and the multifundus groups are muscles of the back.

The fascia found on the surface of the muscle is called the superficial fascia.

The internal oblique muscle is the deepest muscle in the abdominal wall.

Fascia is a general term for the fibrous connective tissue found under the skin and around muscle.

The skeletal muscles are unique because they are the only organs made up of one kind of tissue.

A group of skeletal muscle fibers are called fascicles.

The muscles that move the head are paired muscles on opposite sides of the body.

First- and second-class levers are not as common in the body as third-class levers.

The direction of the fibers composing a muscle is not significant to its function.

When a muscle contracts,the bone moved is the bone of insertion.

Muscles make up about 30% to 40% of our body weight.

The latissimus dorsi muscle is an example of a fusiform muscle.

The orbicularis oris surrounds the eye and allows you to blink.

The epimysium,endomysium,and perimysium may all be continuous with ligaments.

The pectoralis major is an example of a convergent muscle.

With aging,connective tissue replaces some muscle fibers,causing decreased muscle strength.
