Bone markings

Bone Markings

-Bone markings can be classified as either a depression, a projection that helps forms joints (articulation), or projections that are sites of muscle and ligament attachment.

*see page 115 Table 5.1 in text book for further reference.


Projections that are sites of muscle and ligament attachment
Projections that are sites of muscle and ligament attachment

Tuberosity

Crest

Narrow ridge of bone usually prominent.

Palpable

Ex. Iliac Crest

  • Large rounded projection, may be roughened.

    • Palpable

    • Ex. Tibial Tuberosity


Trochanter

Line

Narrow ridge of bone, less prominent than a crest.

Not Palpable

Intertrochanteric Line

  • Very large, blunt irregular shaped process.

    • Palpable

    • Ex. Greater and lesser Trochanter of the Femur


Tubercle

Epicondyle

Raised area on or above a condyle.

Is a site of ligament attachment

Palpable

Ex. Medial and Lateral epicondyle of the Humerus

  • Small rounded projection or process

    • Palpable

    • Ex. Greater and lesser tubercle of the Humerus


Spine

Ramus

Arm-like bar of bone

Palpable

Ex. Mandibular Ramus

  • Sharp, slender often pointed projection.

    • Palpable

    • Ex. Scapular Spine


Projections that help to form joints articulation
Projections that help to form Joints (articulation)

Head

Facet

Smooth nearly flat articular surface.

Not Palpable

Ex. Rib Facet ( connects to the vertebrae)

  • Bony expansion carried on a narrow neck.

    • Not palpable in the Femur or Humerus, but is palpable in the Radius

    • Ex. Femoral Head


Condyle

  • Rounded articular projection

    • Palpable

    • Ex. Femoral condyle


Depressions allow passage of blood vessels and nerves
Depressions (allow passage of blood vessels and nerves)

Meatus

Sinus

Cavity within a bone filled with air and lined with mucous membrane.

Not Palpable

Ex. Sinus in Cranium

  • Canal-like passage way

    • Palpable

    • Ex. External Auditory Meatus


Fossa

Groove

Slit-like furrow

Not Palpable

Ex. Bicipital Groove in Humerus

  • Shallow basin-like depression in bone, often serving as an articular surface.

    • Not Palpable

    • Ex. Glenoid Fossa in Scapula


Fissure

Foramen

Round or oval opening through bone.

Not Palpable

Ex. Vertebral Foramen.

  • Narrow slit-like opening

  • Allows for blood vessel and nerve passage.

    • Not Palpable

    • Ex. Located in Skull
