Shapes of Bones

Long Bones
"Long and slender"

Example: humerus, radius, ulna, femur, tibia, fibula
Shapes of Bones

Flat Bones
"spongy bone sandwich"; thin, roughly parallel surface of compact bone

Example: skull, sternum, ribs, scapula
Shapes of Bones

Sutural Bones
Small, flat oddly shaped bones (rare)

Example: flat bones of the skull in suture line
Shapes of Bones

Irregular Bones
Short, flat, notched or ridged with complex shape

Example: vertebrae, bones of the skull
Shapes of Bones

Short Bones
"Boxlike" in appearance; compact and spongy bone

Example: carpal (wrist) and tarsal (ankle) bones
Shapes of Bones

Sesamoid Bones
Small, round, flat, develop inside tendons near joints

Example: patella
Bone Markings - Elevations and Projections

Process
Any projection or bump

Example: cheekbone
Bone Markings - Elevations and Projections

Ramus
An extension of a bone making an angle to the rest of the structure

Example: mandible
Bone Markings - Processes Where Tendons or Ligaments Attach

Trochanter
A large, rough projection

Example: top epiphyses of long bones, opposite of head
Bone Markings - Processes Where Tendons or Ligaments Attach

Tuberosity
A rough projection

Example: small rough projection on diaphysis of femur
Bone Markings - Processes Where Tendons or Ligaments Attach

Tubercle
A small, rounded projection

Example: Bottom or top epiphyses of femur
Bone Markings - Processes Where Tendons or Ligaments Attach

Crest
A prominent ridge

Example: top of pelvic bone
Bone Markings - Processes Where Tendons or Ligaments Attach

Line
A low ridge

Example: lower line of the pelvis
Bone Markings - Processes Where Tendons or Ligaments Attach

Spine
A pointed process

Example: point of pelvis at end of crest
Bone Markings - Processes Formed for Articulations

Head
The expanded articular end of an epiphyses; often separated by a narrower neck

Example: epiphysis of femur that creates the hip joint
Bone Markings - Processes Formed for Articulations

Neck
A narrower connection between the epiphysis and diaphysis

Example: neck of femur behind head
Bone Markings - Processes Formed for Articulations

Condyle
A smooth, rounded articualr process

Example: entire bottom epiphyses of femur that creates knee joint
Bone Markings - Processes Formed for Articulations

Trochlea
A smooth, grooved articular process shaped like a pulley

Example: bottome grooves of epiphysis of femur that forms the knee joint
Bone Markings - Processes Formed for Articulations

Facet
A small, flat, articular surface

Example: opposite side of the trochlea on the condyle or epiphysis of femur
Bone Markings - Depressions

Fossa
A shallow depression

Example: Under side of epiphysis of femur, above trochlea
Bone Markings - Depressions

Sulcus
A narrow groove

Example: groove near head of femur between head and neck
Bone Markings - Openings

Foramen
A rounded passageway for blood vessels or nerves

Example: canal near cheekbone
Bone Markings - Openings

Fissure
An elongated cleft

Example: canal in orbital for optic nerve
Bone Markings - Openings

Meatus or Canal
A passageway through the substance of a bone; often rough

Example: canal in midbrain region of the skull
Bone Markings - Openings

Sinus or Antrum
A chamber within a bone, normally filled with air

Example: nasal passages leading to sinus canals
