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


highly compressed with great tensile strength


contains collagen fibers


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


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


example of flat bone

irregular bones

bones with complicated shapes


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...


sites of muscle and ligament attachment


a knoblike process usually larger than a tubercle


narrow ridge of bone


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


a line


small, rounded elevation on bone


raised area above a condyle


any pointed projection


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


round "headlike" structure


smooth, nearly flat articular surface


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


armlike bar of bone


canal-like passageway


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


a concavity in a surface (especially an anatomical depression)


any furrow or channel on a bodily structure or part


a long narrow opening


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


tubular shaft that forms the axis of long bones


composed of compact bone that surrounds the medullary cavity

medullary cavity

contains the yellow bone marrow (Fat)


expanded ends of long bones


exterior is compact bone, interior is spongy bone


joint surface is covered with articular cartilage

epiphyseal line

separates the diaphysis from the epiphysis

periosteum, endosteum

two bone membranes


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


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


another word for haversian system


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


mature bone cells


small cavity in bone that contain osteocytes


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