Module 1: General Anatomy and Radiographic Positioning Terminology Flashcards
What is the science of the structure of the body
Anatomy
Study of the function of the organs
Physiology
Detailed study of the knowledge relating to the bones of the body
Osteology
Functions of Bones
- Attachment for muscle
- Mechanical basis for movement
- Protection of internal organs
- Frame to support
- Storage for calcium, phosphorus, and other salts
- Production of RBC and WBC
Bone Structure
- Periosteum
- Endosteum
- Haversian System
- Medullary Cavity
- Spongy Bone
- Cortical Bone
Term given to the development and formation of bones
Ossification
Bones formed from Intermembranous ossification
Skull, clavicles, mandible and sternum
Bones formed from Endochondrial ossification
Short, irregular and long bones
Primary ossification
Diaphysis
Secondary ossification
epiphysis
Classification of Bones
- Long
- Short
- Flat
- Irregular
- Sesamoid
Long Bones (example and function)
Femur, humerus : to provide support
Short Bone (example and function)
Tarsals and wrist : Allow minimum flexibility and motion in a short distance
Flat Bone (example and function)
- Diploe
- Cranium, sternum, scapula
- Provides protection, and their broad surfaces allow muscle attachment
Irregular Bone (example and function)
- Vertebrae & pelvis
- attachment for muscles, tendons and ligaments, or they attach to other bones to create joint
Sesamoid bone (example and function)
Patella
- Developed inside and beside the tendon, and protects it from excessive wear

beaklike or crownlike process
Coracoid or Coronoid
Process and Projections
hornlike process on a bone
Horn
Process and Projections
ridgelike process
Crest
Process and Projections
projection above condyle
Epicondyle
Process and Projections
small, smooth-surfaced process for articulation
Facet
Process and Projections
hook-shaped process
Hamulus
Process and Projections
expanded end of a long bone
Head
Process and Projections
less prominent ridge than a creast, linear elevation
Line
Process and Projections
club-shaped process
Malleolus
Process and Projections
projecting part or prominence
Protuberance
Process and Projections
sharp process
Spine
Process and Projections
long pointed process
Styloid
Process and Projections
either of two large rounded, and elevated process (greater/major and lesser/minor)
Trochanter
Process and Projections
small, rounded and elevated process
Tubercle
Process and Projections
large, rounded elevated process
Tuberosity
Depressions

- Groove
- Meatus
- Notch
- Sinus
- Sulcus
Depressions
cleft, or deep groove
Fissure
Depressions
hole in a bone for transmission of blood vessels and nerves
Foramen
Depressions
pit, fovea or hollow space
Fossa
Depressions
shallow linear channel
Groove
Depressions
tubelike passageway running within a bone
Meatus
Depressions
indentation into the border of a bone
Notch
Depressions
recess, groove or cavity, or hollow space
Sinus
Depressions
furrow, trench or fissurelike depression
Sulcus
Fractures
Does not break through skin
Closed
Fractures
Serious fracture in which the broken bone or bones project through the skin
Open
Fractures
Which the bone retains its normal alignment
Nondisplaced
Fractures
The bones are not in anatomic alignment
Displaced
