The sagittal suture joins the parietal bones.
Correct Answer
TExplanation
The sagittal suture is a dense fibrous joint that connects the two parietal bones of the skull. It runs along the midline of the skull, from the anterior fontanelle (soft spot) to the posterior fontanelle. This suture allows for slight movement between the parietal bones during childbirth and skull growth in infants. In adults, the sagittal suture becomes completely fused, providing stability and protection to the brain. Therefore, the statement that the sagittal suture joins the parietal bones is correct.Rate this question:

Sesamoid bones protect tendons from wear and tear and may improve the mechanical advantage at a joint by altering the direction of pull of a tendon.
Correct Answer
TExplanation
Sesamoid bones are small bones that are embedded within tendons. They act as protective shields, reducing friction and preventing excessive wear and tear on the tendons. Additionally, sesamoid bones can alter the direction of pull of a tendon, which can improve the mechanical advantage at a joint. This means that the tendon can exert more force and have a greater effect on joint movement. Therefore, the statement that sesamoid bones protect tendons from wear and tear and improve the mechanical advantage at a joint is true.Rate this question:

The sacral promontory projects anteriorly from the apex of the sacrum
Correct Answer
base of the sacrumExplanation
The sacral promontory is a prominent bony ridge that projects anteriorly from the apex of the sacrum. It is located at the uppermost part of the sacrum, forming the anterior boundary of the pelvic cavity. The base of the sacrum, on the other hand, refers to the broad, upper surface of the sacrum that articulates with the last lumbar vertebra. Therefore, the correct answer is "base of the sacrum" because the sacral promontory does not project from the base but rather from the apex of the sacrum.Rate this question:

The tubercle of a rib articulates with demifacets on the bodies of adjacent vertebrae
Correct Answer
head of a ribExplanation
The head of a rib articulates with demifacets on the bodies of adjacent vertebrae. The head of a rib is the rounded end that connects to the vertebral column. It has two facets, one that articulates with the superior demifacet on the body of the vertebra above, and another that articulates with the inferior demifacet on the body of the vertebra below. This allows for a stable and flexible connection between the ribs and the vertebrae, facilitating movements such as breathing.Rate this question:
