Bone and Skeletal Tissue Review

Front

Cells that dissolve the bony matrix.

Back

Osteoclasts are specialized cells that break down bone tissue by dissolving the bony matrix.

Front

A narrow slit-like opening in bones is called a ___________.

Back

Fissure is a narrow slit-like opening in bones that allows for the passage of nerves and blood vessels.

Front

Blood vessels use what type of canal to go horizontally?

Back

Perforating canals (also known as Volkmann's canals) are channels that allow blood vessels to travel horizontally through bone.

Front

What is the outer covering of bone that covers the diaphysis and is the location where muscles attach?

Back

Periosteum is the dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

Front

What kind of tissue is the forerunner of long bones in the embryo?

Back

Hyaline cartilage serves as the precursor to long bones during embryonic development.

Front

What is the functional unit of compact bone?

Back

Osteon (or Haversian system) is the structural unit of compact bone, consisting of a central canal surrounded by concentric lamellae.

Front

What is the role of osteoblasts in bone tissue?

Back

Osteoblasts are cells responsible for bone formation; they synthesize and secrete the bone matrix.

Front

What is the term for the small channels that connect lacunae in bone tissue?

Back

Canaliculi are tiny channels that connect lacunae, allowing for communication and nutrient exchange between osteocytes.

Front

What type of cartilage is found at the ends of long bones?

Back

Articular cartilage is a smooth, white tissue that covers the ends of bones where they come together to form joints.

Front

What is the primary mineral found in bone?

Back

Hydroxyapatite is the primary mineral component of bone, providing strength and rigidity.
