Skeletal System: Vocabulary and Appendicular Skeleton
Language of the bones
1. Process- projection– Example: mastoid process and styloid process
2. Articulation- joint– Ex: Temporalmandibular joint (TMJ) – http://www.youtube.com/watch?v=JMOrT10iEdc
3. Fossa- depression of a bone– Ex: Anterior Cranial Fossa
4. Sinus- cavity in the bone– Ex: Sphenoid and ethmoid sinuses
Language of the bones Continued…5. Forman- hole in the bone– Ex: Forman magnum
6. Meatus- tubular structure in a bone– Ex: External Auditory Meatus (Ear hole)
7. Condyles- large smooth curved surfaces forms joint with another bone--Ex: Medial epicondyl
8. Tubercles- Warty outgrowth allows tendons to attach– Ex: greater tubercle
Identify the terms we just learned below 1-7

2 girdles
• A girdle is a collection of bones that attach to the axial skeleton
1. Upper Extremity or Pectoral Girdle: consists of the clavicle and scapula– Connects at the sternoclavicular joint (clavicle and menubrium)
2. Lower Extremity or Pelvic Girdle: consists of illium (hip), ischium (butt), and the pubic bone– Joins to make the acetabulum
Pectoral GirdleAttaches to the upper
extremities to the axial skeleton
• Humerus• Radius• Ulna• Carpals• Metacarpals• Phalanges
Pelvic Girdle
• Attaches the lower extremities to the axial skeleton
Pelvic Girdle
• Lower extremities include:• Femur• Patella• Tibia• Fibula• Tarsals• Metatarsals• Phalanges
