Every bump, groove, and hole has a name on your bones
BONE MARKINGS Every bump, groove, and hole has a name on your bones p.137 Table 7.2
2
BONE MARKINGS PROJECTIONS: Processes that protrude out of bone
DEPRESSIONS Cavities that indent into bone
3
PROCESS PROCESS:A relatively large projection or prominent bump
4
Joint Projections Condyle: Rounded articular projection Condyle
A few slides ahead not the EPICONDYLE… Which would be found above a condyle
5
Joint Projections Head: bony expansion on a narrow neck
Facet: smooth, nearly flat articular surface
6
Joint Projections Ramus: Armlike bar of bone
7
Ligament/Tendon Projections
Crest: Narrow ridge of bone (Line: smaller than a crest) Epicondyle: Raised area on or above a condyle ULNA
8
Tubercle: Small rounded projection
Tuberosity: large rounded or roughened projection Trochanter: very large, blunt projection (only on femur) Proximal Tibia
9
PROJECTIONS Spine: Sharp, pointed projection Thoracic Vertebrae
10
MARKINGS ON THE CRANIUM
Fontanel : soft spot in the skull (infant skull)…cranial bones have not yet fused Suture: interlocking line at the union of 2 bones; fibrous joint in the skull
11
DEPRESSIONS Allow blood vessels or nerves to pass through.
Meatus: (me - A- tus) Canal or tube
12
Depressions Fossa: shallow basin Fissure: narrow, slit-like opening
13
Depressions Sinus: Cavity within a bone; filled with air and lined with mucous membranes Foramen: Round or oval opening Foramen Magnum
14
DEPRESSIONS FOVEA: a small pit or depression
15
Depressions Sulcus, Groove or Furrow: a shallow depression
16
Review: (note on your index cards which markings are projections & which are depressions)
Process Condyle Head Facet Ramus Crest Epicondyle Tubercle Tuberosity Trochanter Spine Depressions Meatus Fossa Fovea Fissure Foramen Sinus Fontanel Suture Sulcus or Groove or Furrow
