What is the function of chondrocytes? - ANSWER-Chondrocytes
maintain cartilage and are found in lacunae.
What is the main characteristic of spongy bone? - ANSWER-It
has a honeycomb structure made of trabeculae with spaces filled
with marrow.
What is appositional growth in cartilage? - ANSWER-It is the
growth where new matrix is laid down on the surface of existing
cartilage.
What is interstitial growth in cartilage? - ANSWER-It is the growth
where chondrocytes divide and secrete new matrix from within,
increasing cartilage length.

What is the perichondrium? - ANSWER-A layer of dense
connective tissue that surrounds cartilage and helps resist
expansion.
What is the composition of the extracellular matrix in cartilage? -
ANSWER-It contains glycosaminoglycans (GAGs) like chondroitin
sulfate and hyaluronic acid.
What happens to cartilage growth during adolescence? -
ANSWER-Cartilage growth ends as the epiphyseal plates close.
What is the function of bone markings? - ANSWER-Bone
markings serve as sites for muscle attachment, joint formation,
and passage for blood vessels and nerves.
What runs through the core of an osteon? - ANSWER-The central
(Haversian) canal, which contains blood vessels and nerve fibers.
What are perforating (Volkmann's) canals? - ANSWER-Canals
lined with endosteum that occur at right angles to the central
,3|Page
canal, connecting blood vessels and nerves of the periosteum,
medullary cavity, and central canal.
What are lacunae? - ANSWER-Small cavities that contain
osteocytes.
What is the function of canaliculi? - ANSWER-Hairlike canals that
connect lacunae to each other and to the central canal, enabling
communication between osteocytes.
What are interstitial lamellae? - ANSWER-Lamellae that are not
part of an osteon; some fill gaps between forming osteons, while
others are remnants of osteons destroyed by remodeling.
What are circumferential lamellae? - ANSWER-Sheets of bone
located just deep to the periosteum that extend around the entire
circumference of the shaft, helping long bones resist twisting.
, 4|Page
What is the primary composition of bone? - ANSWER-Bone is
made up of both organic components (like osteogenic cells and
osteoid) and inorganic components (like hydroxyapatites).
What is osteogenesis? - ANSWER-The process of bone tissue
formation, including the formation of the bony skeleton in embryos
and postnatal bone growth.
What is endochondral ossification? - ANSWER-The process
where bone forms by replacing a hyaline cartilage model, forming
most of the skeleton below the skull.
What is intramembranous ossification? - ANSWER-The process
where bone develops from fibrous connective tissue membranes
containing mesenchymal cells, forming cranial bones and
clavicles.
What are the four major steps of intramembranous ossification? -
ANSWER-1. Ossification centers form. 2. Osteoid is secreted and
calcified. 3. Woven bone is formed. 4. Lamellar bone replaces
woven bone.
