Fill-in-the-blank flashcards to help students review key concepts from the lecture on OIOS tissue and bone structure.

The skeletal system is made up of __, cartilage, ligaments, and various connective tissues.

skeletal bones

The two major divisions of the skeleton are the skeleton and the skeleton.

axial, appendicular

The axial skeleton includes the skull, thorax, and __ column.

vertebral

The __ skeleton comprises all of the appendages attached to the axial skeleton.

appendicular

Bones serve as a major reservoir for essential minerals such as __ and phosphate.

calcium

Erythrocytes (red blood cells) and leukocytes (white blood cells) are produced in the __ marrow.

bone

Muscles __ on bones to produce movement.

pull

Osteocytes are mature bone cells trapped within the __ matrix.

bone

The process of bone formation is known as __.

osteogenesis

Osteoblasts are responsible for __ bone formation.

secreting

The __ are large multi-nucleated cells that dissolve bone matrix.

osteoclasts

The two types of bone tissue are bone and bone.

compact, spongy

Compact bone forms the outer layer of the bone and is characterized as __ and solid.

dense

The structural unit of compact bone is called an __.

osteon

Spongy bone consists of an open network of thin branching plates called __.

trabeculae

In the process of intramembranous ossification, initial bone formation occurs in the __ center.

ossification

The __ is a thin layer of cartilage found between the epiphyses and diaphysis in growing bones.

epiphyseal plate

The increase in diameter of bones during growth is due to __ bone growth.

appositional

The __ line marks the former location of the epiphyseal cartilage, indicating that growth has stopped.

epiphyseal

With aging, bone remodeling becomes unbalanced, leading to __ loss and an increase in fracture risk.

bone density
