Cerebral vascular disease in Children - Correct Answers
✅Blood clotting mechanism includes antithrombin enzyme
activity, protein C, protein S deficiencies, or abnormal factor
IV Leiden.
Hepatitis - Correct Answers ✅Hepatic cell necrosis,
scaring, kupffer cell hyperplasia, and infiltration by
mononuclear phagocytes occur with varying severity.
Bone cells - Correct Answers ✅3 types; Osteoblasts,
osteoclasts, & osteocytes
Osteoblasts - Correct Answers ✅originate from
mesenchymal stem cells (MSC's), alter levels of RANKL and
osteoprotegerin (OPG); the balance of these two cytokines
determines overall osteoclast formation
osteocytes - Correct Answers ✅most abundant cells in
bone, final differentiation stage for an osteoblast;
Transformed osteoblasts that become trapped or surrounded
in osteoid as it hardens. Stored within the lacuna (space
within the hardened bone matrix) Primary function-act as a
mechanoreceptor - how bone responds to changes in weight-
bearing or other stressors on the bone such as hormone
changes, mechanical stressors. Function as endocrine
receptors - Regulates bone metabolism and Parathyroid
hormone (PTH). know when something happens to

mechanoreceptors, osteocytes detect this, send signals to
multiple molecules, and then bone remodeling begins.
Osteoclasts - Correct Answers ✅terminally differentiated
multinucleated bone cells; Responsible for bone resorption,
Resorb bone by secretion of hydrochloric acid, acid proteases,
and matrix metalloproteinases. Resorb bone through the
action of lysosomes filled with hydrolytic enzymes in their
mitochondria
What is bone formation initiated by? - Correct Answers
✅Osteoblasts, Inorganic Calcium phosphate is produced,
Active on the outer surface of bones, forming a single layer of
cells, Responsible for parathyroid hormone and produce
protein call osteocalcin when stimulated by 1,25-dihydroxy-
Vit D3
types of bone tissue - Correct Answers ✅Compact bone
(cortical bone) constitutes 85% of skeleton & Spongy Bone
(cancellous bone) constitutes 15% of skeleton
Joints - Correct Answers ✅Primary function -provide
stability and mobility of the skeleton
Classifications of joints - Correct Answers ✅Connective
structures -Fibrous, Cartilaginous, & Synovial
,Advanced Patho Exam 4 Latest Update
2026 (Questions and Answers-Verified
solutions)
Movement-synarthrosis (immovable joint): Amphiarthrosis
(slightly movable joint), Diarthrosis (freely movable joint)
Fibrous joints - Correct Answers ✅Joints are united directly
to the bone by fibrous connective tissue.
Cartilaginous joints - Correct Answers ✅two types -
symphysis (united by pad or disk of fibrocartilage) &
synchondrosis (hyaline cartilage rather than fibrocartilage
connect the two bones.)
Synovial joints - Correct Answers ✅the most movable and
most complex joints in the body.
disorders of bones - Correct Answers ✅OSTEOPOROSIS,
OSTEOPENIA, & OSTEOMYELITIS
Osteoporosis - Correct Answers ✅most common bone
disease, Develops during remodeling cycle, Characterized by
low bone mineral density, the impaired structural integrity of
the bone, decreased bone strength, and the risk of a fracture.
Mostly seen in white women. Two types: Primary (Idiopathic
osteoporosis) & Secondary
, Advanced Patho Exam 4 Latest Update
2026 (Questions and Answers-Verified
solutions)
primary or idiopathic osteoporosis - Correct Answers
✅develops with age during bone reabsorption and bone
formation
secondary osteoporosis - Correct Answers ✅is caused by
other conditions such as endocrine diseases (hormone
imbalances, diabetes, hyperparathyroidism,
hyperthyroidism), medications (heparin, corticosteroids,
Phenytoin, barbiturates, lithium), tobacco, and ethanol.
Clinical manifestations of osteoporosis - Correct Answers
✅bone deformity, Pain with a fragility fracture, Kyphosis
(caused by vertebral collapse), Diminished Height, Fractures,
Treatment: depends on the underlying cause. Focus on
prevention (Oral Ca)
Osteoporosis is most common in what population? - Correct
Answers ✅women at a rate of one in two women,
Postmenopausal Osteoporosis-estrogen deficiency. 1 in 4 men
experiences osteoporosis. Clinicians use Fracture Risk
Assessment to identify 10 years probability of fracture by
using clinical risk factors along with bone mineral density.
how is osteoporosis measured? - Correct Answers
✅Measured using dual xray absorptiometry (DEXA), What
Your T-score Means - According to the World Health
Organization (WHO):
