Bone Markings Flashcards
Foramen
Hole through which blood vessels, nerves, and ligaments pass.
4 foramens
1) vertebral foramen- encases spinal cord
2) obturator foramen- in ischium, obturator nerve
3) intervertebral foramen- formed by superior/inferior notch of vertebrae
4) transverse foramen- hole for arteries in cervical spine
Fossa
Hollow or depression
4 fossa’s
1) glenoid fossa- lateral scapula where it attaches to humerous
2) coronoid fossa- distal anterior surface of humerous
3) olecronon fossa- distal posterior surface of humerous
4) intercondylar fossa- posterior surface of distal femur between medial and lateral condyle
Groove
Ditchlike groove containing a tendon or blood vessel
1 groove
Bicipital groove- proximal anterior humerous dividing greater and lesser tuberosity, where bicep tendon runs
Meatus
Canal or tubelike opening in a bone
1 meatus
External auditory meatus- hole where ear is (behind TMJ)
Sinus
Air filled cavity within a bone
3 sinus
1) sinus tarsai- between talus and calcaneus of foot
2) frontal sinus- inside skull above and between eyes
3) maxillary sinus- skull on either side of nose
Condyle
Rounded knuckle like projection
3 condyle
1) mandibular condyle- on skull TMJ
2) medial and lateral condyle of femur- distal end
3) medial and lateral condyle of tibia- proximal end
Eminence
Projecting, prominent part of bone
1 eminence
Intercondylar eminence of tibia- superior proximal tibia
Facet
Flat or shallow articulate surface
3 facets
1) superior coastal facet on body of vertebrae- only found on T1-T10
2) transverse coastal facet on transverse process of vertebrae
3) inferior and superior articular facet of vertebrae
Head
Rounded articular projection beyond narrow neckline portion of bone
4 heads
1) femoral head
2) humeral head
3) fibular head
4) ulnar head
Crest
Sharp ridge or border
3 crests
1) iliac crest
2) intertrochanteric crest
3) tibial crest
Epicondyle
Prominence above or on condyle
2 epicondyles
1) medial epicondyle of humerous
2) lateral epicondyle of femur
Lines
Less prominent ridge
2 lines
1) linea aspera of femur
2) intertrochanteric line of femur
Spines
Long, thin projection
5 spines
1) posterior superior iliac spine
2) anterior superior iliac spine
3) posterior inferior iliac spine
4) anterior inferior iliac spine
5) scapular spine
Trochanter
Very large prominence for muscle attachment
2 trochanters
1) greater trochanter of femur
2) lesser trochanter
Tubercle
Small, rounded projection
1 tubercle
Adductor tubercle
Tuberosity
Large, rounded projection
7 tuberosity
1) lesser tuberosity of humerous
2) greater tuberosity of humerous
3) deltoid tuberosity
4) radial tuberosity
5) Ischial tuberosity
6) tibial tuberosity
7) calcaneal tuberosity
Process
Projection or outgrowth of tissue from larger body
6 processes
1) mastoid process
2) acromion process
3) coronoid process
4) olecronon process
5) radial styloid process
6) ulnar styloid process
Vertebral column levels:
C7, T3, and T7
C7= most prominent cervical vertebrae
T3= same level as scapular spine
T7= same level as inferior level of spine
