Anatomy 1

Condyle

Rounded process that usually articulates with another bone

Crest

Narrow, ridgelike projection

Epicondyle

Projection situated above a condyle

Facet

Small, nearly flat surface

Fissure

Cleft or groove

Fontanel

Soft spot in the skull where membranes cover the space between bones.

Foramen

Opening through a bone that usually serves as a passageway for blood vessels, nerves, or ligaments.

Fossa

Relatively deep pit or depression

Fovea

Tiny pit or depression

Head

Enlargement on the end of a bone

Linea

Narrow ridge

Meatus

Tubelike passageway within the bone

Process

Prominent projection of a bone

Ramus

Branch or similar extension

Sinus

Cavity within a bone

Spine

Thornlike projection

Sulcus

Furrow or groove

Suture

Interlocking line of union between bones

Trochanter

Relatively large process

Tubercle

Knoblike process

Tuberosity

Knoblike process usually larger than a tubercle

what are bones in the skeletal system

ORGANS

Bones are multifunctional:

Support, Protection, provide points of attachment for muscles, Produce blood cells, and store inorganic salts

bones similarities

structure, development, function

Bones of the Skeletal System vary in

Size and shape

Long bones

long and narrow, have expanded ends

EXAMPLE: FEMUR

\

Short Bone

Cubelike, length = width

Include sesamoid (ROUND) bones

are embedded in tendons

Flat Bone

Platelike, with broad surfaces

\

Irregular Bones

Vary in shape, tent to be connected to other bones

LONG BONE PART:

Epiphysis

expanded end

LONG BONE PART:

Diaphysys

bone shaft

LONG BONE PART:

Metaphysis

between diaphysis and epiphysis, widening part

\

LONG BONE PART:

Articular cartilage

covers epiphysis

LONG BONE PART:

Periosteum

encloses bone; dense connective tissue

LONG BONE PART:

Compact (CORTICAL) bone

wall of diaphysis

LONG BONE PART:

Spongy (cancellous) bone

makes up epiphyses

LONG BONE PART:

Trabeculae

branching bony plates, make up spongy bone

LONG BONE PART:

Medullary cavity

hollow chamber in diaphysis; contains marrow

LONG BONE PART:

Endosteum

lines spaces, cavity

LONG BONE PART:

Bone narrow

red or yellow marrow, lines medullary cavity, spongy bone spaces
