articular cartilage
what is chronic fatigue syndrome - answer-(Myalgic encephalomyelitis)- a debilitating
and complex disorder characterized by profound fatigue, musculoskeletal pain,
cognitive impairment, unrefreshing sleep, impaired neurologic energy production, and
immune impairments.
what layer of the skin has langerhans-cells with dendritic processes and immune
function - answer-epidermis
what is a vesicle - answer-elevated, superficial, filled with serous fluid, less than 1cm.
Ex-herpes, varicella
, what is a bulla - answer-vesicle greater than 1cm- Ex- blister
what are telangictasias - answer-fine, irregular red lines produced by capillary dilation
Which type of collagen provides the scaffolding of articular cartilage? - answer-Collagen

What is the term for a chronic inflammatory joint disease characterized by stiffening
and fusion of the spine and sacroiliac joints? - answer-Ankylosing spondylitis is the
result of chronic inflammation in the spine and sacroiliac joints resulting in stiffening
and fusion of the spine.
what is osteomyelitis - answer-infection of bone
Describe the most likely route by which the microorganisms reached the patient's bone.
Submit and Compare, displayed below - answer-The microorganisms likely reached her
bone by extension from the nearby infected ulcer at the base of her big toe.
Name the microorganism that is most likely causing the osteomyelitis.
Submit and Compare, displayed below - answer-staphylococcus aureus is the most
common pathogen, although many diabetic foot ulcers are polymicrobial infections.
Describe sequestrum. - answer-Sequestrum is an area of necrotic bone that separates
from the healthy bone.
What is the most common cause of a corner metaphyseal fracture in a child younger
than 12 months of age? - answer-A transverse tibia fracture resulting in a straight
horizontal break across the tibial shaft is a common cause of a corner metaphyseal
fracture in a child under 12 months of age. A transverse fracture is caused by direct
force, often involving the metaphysis, and is considered a sign of suspected physical
abuse, though transverse fractures could be caused by other types of trauma. A spiral
