Lab 2 - Skeletal System Flashcards
Projections
sites for tendon and ligament attachments
Different Projections
- Crest: ridge
- Epicondyle: superior to condyle
- Line/linea: slightly raised ridge
- Process: prominent
- Protuberance: outgrowth
- Ramus: extension
- Spine: thornlike
- Trochanter: large process on femur bone
- Tubercle: small knoblike
- Tuberosity: rough elevation
Articulation
where bones connect at a joint or articulate with each other
Types of Articulations
- Condyle: rounded process
- Facet: nearly flat
- Head: expanded end
- Facet: nearly flat
Depression
recessed areas in bones
Types of Depressions
- Alveolus: socket
- Fossa: shallow depression
- Sulcus: a groove or fissure
- Fovea: tiny pit or depression
- Notch: gap in an edge of a structure
Openings
open spaces in bones:
Types of Openings
- Canal: tubular passage
- Fissure: slit
- Foramen: hole
- Meatus: tubelike opening
- Sinus: air filled cavity
