Bone Structure & Function
This bone type is longer than it is wide and acts as a lever to aid movement.
What are long bones?
These "foremen" cells monitor and maintain bone structure in response to stimuli.
What are osteocytes?
This type of connective tissue attaches a bone to another bone.
What are ligaments?
These joints connect bones with collagen fibers and are mostly immovable.
This is the primary function of the muscular system.
What is movement?
The two types of bone tissue found in most bones; one is dense and smooth, the other is porous.
What are compact (cortical) and spongy bone?
These cells are the "builders" that construct bone by calcifying it.
The less movable a joint is, the more of this quality it possesses.
What is stability?
These joints connect bones with cartilage and can be slightly movable.
What are cartilaginous joints?
Muscles always do this to produce movement.
What is pull?
This term refers to the process of blood cell formation occurring in red bone marrow.
What is hematopoiesis?
These cells regenerate bone by absorbing tissue that is no longer needed.
What are osteoclasts?
The movable bone during a muscle contraction is known as this.
What is the insertion?
All joints in this category are diarthroses (freely movable).
What are synovial joints?
This type of muscle contraction causes a change in the length of the muscle.
What is isotonic?
The basic structural unit of compact bone, shaped like a long weight-bearing pillar.
What is an osteon?
The process of bone tissue formation, which begins in the embryo at week 8.
What is ossification (osteogenesis)?
A movement that decreases the angle of a joint, bringing articulating bones closer.
What is flexion?
This specific synovial joint allows for the most maneuverability, such as in the shoulder.
What is a ball and socket joint?
This classification of muscle is most responsible for producing a specific movement.
What is a prime mover (or agonist)?
These tiny bone struts are found within spongy bone and are precisely oriented to help the bone resist stress; they also create the spaces where red bone marrow is housed.
What are trabeculae?
This four-stage repair process begins with a hematoma and ends with remodeling to ensure the bone does not become brittle due to crystallized calcium.
What is the process of fracture repair?
During a contraction, this point of muscle attachment stays relatively still and acts as the anchor, while the other end moves toward it.
What is the Origin?
Synovial joints contain this fluid-filled space that acts as a lubricant.
What is the joint (articular) cavity?
These specific synergist muscles immobilize a bone's origin to provide a stable base for the prime mover.
What are fixators?
