Skeletal Cartilage

Contains no blood vessels or nerves

Skeletal cartilage

surrounded by the perichondrium

hyaline, elastic, fibrocartilage

three types of skeletal cartilage

Hyaline cartilage

provides support flexibility and resilience

Hyaline cartilage

most abundant skeletal cartilage

Articular Hyaline Cartilage

covers the ends of long bones

Costal Hyaline cartilage

connects the ribs to the sternum

respiratory hyaline cartilage

makes up larynx

nasal hyaline cartilage

supports the nose

elastic cartilage

similar to hyaline cartilage, but contains elastic fibers

elastic cartilage

found in the external ear and the epiglottis

fibrocartilage

highly compressed with great tensile strength

fibrocartilage

contains collagen fibers

fibrocartilage

found in menisci of the knee and intervertebral disks

Appositional, Interstitial

two ways cartilage grows

Appositional growth

cells in perichondrium secrete matrix against the external face of existing cartilage

Interstitial growth

lacunae bound chondrocytes inside cartilage divide and secrete new matrix, expanding from within

During normal bone growth, during old age

When does calcification occur?

Axial, appendicular

Two skeletons of the body

Axial Skeleton

bones of the skull, vertebral column, and rib cage

appendicular skeleton

bones of the upper and lower limbs, shoulder, and hip

Long bones

longer than they are wide

Humerus

example of a long bone

Short bones

cube shaped bones of the wrist and ankle

short bones

bones that form within tendons (patella)

Flat bones

thin flattened, and a bit curved

sternum

example of flat bone

irregular bones

bones with complicated shapes

vertebrae

example of irregular bone

Support, mineral storage, protection, movement, blood cell formation

5 functions of bones

sites of attachment, joint surfaces, conduits for blood vessels and nerves

bone markings serve as...

projections

sites of muscle and ligament attachment

tuberosity

a knoblike process usually larger than a tubercle

crest

narrow ridge of bone

trochanter

Very large, blunt, irregularly shaped process (the only examples are on the femur)

line

a line

turbercle

small, rounded elevation on bone

epicondyle

raised area above a condyle

spine

any pointed projection

process

a natural prolongation or projection from a part of an organism either animal or plant

head

round "headlike" structure

facet

smooth, nearly flat articular surface

condyle

a round bump on a bone where it forms a joint with another bone

ramus

armlike bar of bone

meatus

canal-like passageway

sinus

any of various air-filled cavities especially in the bones of the skull

fossa

a concavity in a surface (especially an anatomical depression)

groove

any furrow or channel on a bodily structure or part

fissure

a long narrow opening

foramen

Round or oval opening through a bone

compact bone, spongy bone

textures of bone

compact bone

dense outer layer of bone

spongy bone

honeycomb of trabeculae filled with yellow bone marrow

diaphysis, epiphysis

long bones consist of two parts

diaphysis

tubular shaft that forms the axis of long bones

diaphysis

composed of compact bone that surrounds the medullary cavity

medullary cavity

contains the yellow bone marrow (Fat)

Epiphysis

expanded ends of long bones

epiphysis

exterior is compact bone, interior is spongy bone

epiphysis

joint surface is covered with articular cartilage

epiphyseal line

separates the diaphysis from the epiphysis

periosteum, endosteum

two bone membranes

periosteum

double layered protective membrane on the outside of the bone

dense connective tissue

outer layer of periosteum is made of

osteoblasts, osteoclasts

inner osteogenic layer of periosteum is made of

nerve fibers, blood, lymphatic vessels

periosteum supplied with

nutrient foramina

nutrients enter the bone via

sharpey's fibers

periosteum secured to the bone by

endosteum

delicate membrane covering internal surfaces of the bone.

short, irregular, flat bones

thin plates of periosteum covered compact bone on the outside, with endosteum covered spongy bone on the inside

Short, irregular, flat bones

have no diaphysis or epiphyses

short, irregular, flat bones

contain bone marrow between the trabeculae

hematopoietic tissue

red marrow

medullary cavity and all areas of spongy bone

hematopoietic tissue in infants is found:

diploe of flat bones, head of the femur, head of the humerus

red marrow in adults

haversian system

another word for osteon

osteon

another word for haversian system

lamella

weight bearing, column like matrix tubes composed mainly of collagen

haversian or central canal

central channel containing blood vessels and nerves

volkmann's canals

channels lying at right angles to the central canal, connecting blood and nerve supply of the periosteum to that of the haverisan canal

osteocytes

mature bone cells

lacunae

small cavity in bone that contain osteocytes

canaliculi

hairlike canals that connect lacunae to each other and the central canal
