WGU D203 EXAM LATEST VERSION QUESTIONS AND
CORRECT ANSWERS
The cranium, rib cage, and spinal column make up the axial skeleton, which is
the ANSWER portion of the skeletal system.
The limbs' bones and girdles that are connected to the axial skeleton make up
the appendicular skeleton.
Classification of Bones: ANSWER: Sesamoid, flat, irregular, long, and short
bones
Long bones serve as levers that allow the skeletal muscles to move.
Short bone: ANSWER When articulated together, they permit a limited amount
of variable mobility.
Flat bones: ANSWER They serve as attachment points for muscles and shield
the delicate interior structures.
Because of their intricate shape, irregular bones—ANSWER—cannot be
categorized under any of the other headings.
Small, rounded bony nodules called sesamoid bones are seen in tendons when
they cross angular structures like the knee, hand, wrist, or foot.
A joint is a location in the body where two bones meet.
There are three different kinds of joints: synovial, cartilaginous, and fibrous.
Inflexible layers of dense connective tissue make up fibrous joints, which firmly
hold the bones together.
, cartilaginous joints, which are made up of bones joined solely by cartilage,
provide very little movement.
Synovial joints: ANSWER joints that can move freely
ANSWER joints, which provide little to no mobility, are immobile joints.
Only a limited amount of bone mobility is permitted by the partially moveable
joint.
ANSWER, or moveable joints, are often supported by ligaments and have a
synovial capsule.
ANSWER: Cartilage is a more pliable connective tissue than bone that shields
and prevents bone ends from rubbing against one another.
Bone to bone is connected by a ligament.
ANSWER Tendon: Connects muscle to bone
Bone function-ANSWER-assistance
-defense
-make room in your body for calcium in order to preserve homeostasis.
The red bone marrow produces blood cells through a process called
hematopoiesis.
Classification of Muscles: ANSWER cardiac, smooth, and skeletal
Skeletal muscle: ANSWER A muscle that is joined to the skeleton's bones and
offers the force necessary to move them.
Many of the body's interior organs contain smooth mucle, an involuntary
muscle.
ANSWER: cardiac muscle is involuntary muscular tissue that is exclusive to the
heart.
