The adult human skeleton consists of 206 named bones.

Infants have more bones because not all bones have fused.

Axial skeleton – 80 bonesLongitudinal axis (center of the body)Bones arranged along the axis: skull bones,

auditory ossicles, hyoid bone, ribs, breastbone, and backbone

Appendicular skeleton – 126 bonesUpper and lower limbs (extremities), girdles

(connect limbs to axial skeleton)

Depressions and OpeningsSites allowing the passage of soft tissue

(nerves, blood vessels, ligaments, tendons) or formation of joints.

ProcessesProjections or outgrowths on bone that form

joints or attachment points for connective tissue, such as ligaments and tendons).

Fissure – narrow slitForamen – opening (hole)Fossa – shallow depression (trench)Sulcus – furrow (groove)Meatus – tubelike opening (passageway)

Processes that form jointsCondyle – Large, round protuberance at the

end of a bone (knuckle)Facet – smooth, flat articular surfaceHead – rounded articular projection supported

on the neck of a bone

Processes that form attachment pointsCrest – prominent ridge or elongated

projectionEpicondyle – projection above a condyleLine – long narrow ridge or borderSpinous process – sharp, slender projectionTrochanter – very large projectionTubercle – small, rounded projectionTuberosity – large, rounded projection

Membrane-filles spaces between the cranial bones

“soft spots”Allow the skull to change shape as it passes

through the birth canal
