I found these questions online to help me study for my Anatomy Exam in the morning so I just wanted to know if anybody knew the right answers! :)

D)

None of the above

14.

Which of the following statements accurately defines extension?

A)

Movement of a limb away from the midline of the body

B)

A motion that increases the angle between two bones

C)

An extension of the sarcolemma that dives into the muscle fiber and surrounds myofibrils

D)

The ability of each muscle to stretch and rotate with each movement

15.

Which of the following statements accurately defines abduction?

A)

Dark regions of the striations in skeletal muscle tissue that consist of thick and thin filaments or thick filaments only

B)

Movement of a limb away from the midline of the body

C)

Light regions of the striations in skeletal muscle tissue that consist of thin filaments only

D)

16.

Which of the following statements accurately defines adduction?

A)

Dark regions of the striations in skeletal muscle tissue that consist of thick and thin filaments or thick filaments only

B)

Movement of a limb away from the midline of the body

C)

Light regions of the striations in skeletal muscle tissue that consist of thin filaments only

D)

Movement of a limb toward the midline of the body

17.

Which of the following statements accurately defines circumduction?

A)

Movement of a part in a cone-shaped radius

B)

A joint where the articular surfaces fit together as a saddle

C)

Having a striped appearance

D)

Both A and C are correct

18.

Which of the following statements accurately defines rotation?

A)

Rotating the radius around the ulna so that the palm faces anteriorly

B)

Tissue made of long, tubular, and striated muscle fibers with multiple nuclei

C)

Movement of a bone about its own axis

D)

13.	Which of the following statements accurately defines flexion?
	A)	A motion that decreases the angle between two bones
	B)	Provides strength for structures that require tensile strength such as tendons, ligaments, joints, and organ capsules
	C)	A motion that increases the angle between two bones
	D)	None of the above

Solution

1 3.option A. A motion that decreases angle between two bones.

Extension is the opposite of flexion where angle increases

14. Option B. A motion that increases the angle between two bones.

15.option B. The movement of a limb away from the midline of the body.

16.D.movement of the limb towards the midline of the body.

17.A. The movement of a part in cone shaped radius.

18.C. Movement of a bone about its own axis.
