Structure Of Bone Tissue Flashcards
Bone tissue exists in two forms (2)
Compact
Spongy
Compact bone called
Spongy bone called
Cortical
Cancellous
Compact make up _ of all bones
Outer covering
Compact bone made up of a series of _ and _
Canals
Passageways
Canals and passageways provide a route for nerves, blood vessels, and _ to extend through bone
Lymphatic vessels
Structural units of compact bones are called _
Osteons
Structural units of compact bones (osteons) are elongated cylinders which lie parallel to _
Long axis of the bone
Osteons are composed of a group of _
Lamellae
Osteons are composed of a group of lamellae of _ arranged concentrically
Lamellae are _
Hollow tubes
Lamellae arranged in way that _ in adjacent lamellae run in opposite directions
Collagen fibers
Collagen fibers running in opposite directions intended to reinforce bone against _
Twisting forces
Each osteon is nourished by _
Blood vessels
Each Osteons is served by _ which run throughout its center
Nerve fibers
Center where nerve fiber runs is called the _
Haversian canal
The _ canals connect blood vessels and nerve supply of the periosteum to those in central canals and medullary cavity
Volksmann’s
The volksmann’s canals connect blood vessels and nerve supply of the _ to those in central canals and medullary cavity
Periosteum
The volksmann’s canals connect blood vessels and nerve supply of the periosteum to those in central canals and _
Medullary cavity
Periosteum is the _
Membrane around bone
Medullary cavity contains _
Bone marrow
Mature bone cells (osteocytes) are located in small cavities between each _
Lamella
Small cavities in which osteocytes live are called _
Lacunae
