Question 1

MATCHING
Match the stages of wound healing of a bone with the description of each.Stages may be used more than once.
-Osteoblasts form membranous or woven bone.Enzymes increase the phosphate content and permit the phosphate to join with calcium to be deposited.
A)Callus replacement
B)Hematoma formation
C)Remodeling
D)Procallus formation
E)Callus formation

Accepted Answer

Callus formation is the stage where osteoblasts form membranous or woven bone, and enzymes increase the phosphate content and permit the phosphate to join with calcium to be deposited.

Answer: A and C
 Callus replacement is the stage where the woven bone is replaced by lamellar bone, while remodeling is the stage where the bone is reshaped and strengthened. Both of these descriptions match the stages of wound healing of a bone.

Question 3

Which of the following describes a functional muscle contraction in which the muscle contracts but the limb does not move?
A) Isotonic contraction
B) Isometric contraction
C) Eccentric contraction
D) Concentric contraction

Accepted Answer

Isometric contraction is a functional muscle contraction in which the muscle contracts but the limb or joint does not move, and the length of the muscle remains the same. This type of contraction is useful for maintaining posture and stability.

Question 4

MATCHING
Match the stages of wound healing of a bone with the description of each.Stages may be used more than once.
-Stage of bone healing that requires years to complete.
A)Callus replacement
B)Hematoma formation
C)Remodeling
D)Procallus formation
E)Callus formation

Accepted Answer

Remodeling is the stage of bone healing that requires years to complete as it involves the gradual reshaping and strengthening of the bone to its optimal form and function.

Answer: B
 Hematoma formation is the initial stage of bone healing where blood vessels break and blood pools in the injured area, leading to the formation of a blood clot or hematoma.

Answer: D
 Procallus formation, also known as the inflammatory stage, is the second stage of bone healing where the body initiates an inflammatory response to promote healing and restore tissue function.

Answer: E
 Callus formation is the third stage of bone healing where the body forms a soft callus made of collagen and cartilage to bridge the broken bone ends and provide support for the new bone growth.

Answer: A
 Callus replacement, also known as the bone remodeling stage, is the final stage of bone healing where the soft callus is gradually replaced by hard bone tissue through a process called ossification. This stage can also take years to complete depending on the severity of the injury.

Question 5

In _____ contractions,the muscle maintains a constant tension as it moves.
A) isotonic
B) isometric
C) hypertonic
D) hypotonic

Accepted Answer

Isotonic contractions occur when the muscle maintains a constant tension as it moves, such as when lifting a weight or performing a bicep curl. Isometric contractions, in contrast, occur when the muscle contracts but does not change length, such as when pushing against an immovable object. Hypertonic refers to a condition where the muscle is excessively tense or contracted, while hypotonic refers to a condition where the muscle is insufficiently tense or contracted.

Question 6

MATCHING
Match the stages of wound healing of a bone with the description of each.Stages may be used more than once.
-Fibrin and platelets form a meshwork within the initial framework for healing.
A)Callus replacement
B)Hematoma formation
C)Remodeling
D)Procallus formation
E)Callus formation

Accepted Answer

Hematoma formation is the initial stage of bone healing, during which blood clotting occurs and a hematoma (localized swelling filled with blood) forms at the site of injury.

Answer: D
 Procallus formation is the second stage of bone healing, during which the hematoma is replaced by a fibrous network of cells that secrete collagen and other extracellular matrix components.

Answer: E
 Callus formation is the third stage of bone healing, during which the fibrous network is mineralized to form a hard callus that stabilizes the fracture site.

Answer: C
 Remodeling is the final stage of bone healing, during which the callus is reabsorbed and replaced by new bone tissue that matches the surrounding bone structure. This process can take several months to several years to complete.

Answer: A
 Callus replacement is not a recognized stage of bone healing.

Question 7

MATCHING
Match the stages of wound healing of a bone with the description of each.Stages may be used more than once.
-Stage of bone healing that requires hours to complete.
A)Callus replacement
B)Hematoma formation
C)Remodeling
D)Procallus formation
E)Callus formation

Accepted Answer

Hematoma formation occurs immediately after a bone fracture and lasts for several hours.

Answer: D
 Procallus formation occurs within the first few days after a fracture, as fibroblasts and chondroblasts begin to produce collagen and cartilage.

Answer: E
 Callus formation occurs in the weeks after a fracture, as the newly formed cartilage is gradually replaced by bone tissue.

Answer: A
 Callus replacement occurs several weeks to several months after a fracture, as the newly formed bone tissue is remodeled and strengthened.

Answer: C
 Remodeling of the bone to restore its original shape and strength can take several months to several years to complete, depending on the severity of the fracture.

Question 8

MATCHING
Match the stages of wound healing of a bone with the description of each.Stages may be used more than once.
-Stage of bone healing that requires weeks to complete.
A)Callus replacement
B)Hematoma formation
C)Remodeling
D)Procallus formation
E)Callus formation

Accepted Answer

Callus formation is the stage of bone healing that requires weeks to complete as it involves the formation of a fibrocartilaginous callus around the fracture site.

Answer: A, C
 Callus replacement and remodeling are both stages of bone healing that occur after the initial formation of the callus. Callus replacement involves the replacement of the fibrocartilaginous callus with a bony callus, while remodeling involves the reshaping and strengthening of the bone.

Question 9

Which statement is false about aging and the musculoskeletal system?
A) Haversian systems erode,canals nearest the marrow cavity become widened,and the endosteal cortex converts to spongy bone.
B) The remodeling cycle increases because of a decreased ability of the basic multicellular units to resorb and deposit bone.
C) Cartilaginous rigidity increases because of decreasing water content and increasing concentrations of glycosaminoglycans.
D) Muscle RNA synthesis declines,although the regenerative function of muscle tissue is reportedly normal in the elderly population.
