Skeletal System Bone tissue

an organ made up of several different tissues working together

the entire framework of bones and their cartilages constitute of

the study of bone structure and the treatment of bone disorders is referred as

osteo means

logy means

give 5 functions of skeletal system

a bone that one has greater length than width

(growing between) bone's shaft or body. Long,cylindrical and main portion of the bone.

(growing over) the proximal and distal ends of the bone.

(between) regions between the diaphysis and epiphyses

(growth plate) a layer of hyaline cartilage that allows the diaphysis of the bone to grow in legth

thin layer of hyaline cartilage covering the part of the epiphysis

Tough connective tissue sheath and its associated blood supply

Peri- means

marrow cavity, hollow, cylindeical space within the diaphysis that contains fatty yellow bone marrow

Medulla means

a thin membrane that lines the medullary cavity.

Endo means

what is the extracellular matrix?

what is the most abundant mineral salt?

it combines with another mineral salt, calcium hydroxide to form crystals of?

mineral crystallizes and the tissue hardens

bone building cells

depends on the crystallized inorganic mineral salts

depends on its collagen fibers

Bone cells are called?

4 types of cells present in bone tissue

unspecialized bone stem cells derived from mesenchyme

synthesize and secrete collagen fibers and other organic components (bone building cells)e

(mature bone cells) main cells in bone tissue and maintain ita daily metabolism

huge cells derived from the fusion of as many as 50 monocytes

breakdown of bone extracellular matrix. normal development, maintenance and repair of bone.

Bone is not completely solid but has many small spaces between its cells and extracellular matrix components

some spaces serve as channels for blood vessels that supply bone cells with nutrients. other spaces act as storage areas for red bone marrow.

80% of skeleton is?

20% of skeleton is?

Strongest form of bone tissue. Provides protection and support and resists the stresses.

Repeating structural units called osteons or?

circular plates

(small channel) filled with extracellular fluid

Between the concentric lamellae are small spaces called?

Trabecular or cancellous bone tissue. Does not contains osteons.Always located in the interior of a bone protected by a covering of compact bone

Filled with red bone marrow and yellow bone marrow

Spongy bone is light, which reduces the overall weight of a bone

Passes through a hole in compact bone called the nutrient foramen

Enter the metaphyses of a long bone

Enter the epiphyses of a long bone

On going replacement of old bone tissue by new bone tissue

The removal of minerals and collagen fibers from bone bt osteoclasts

The addition of minerals and collagen fibers to bone by osteoblasts
