1 Upper Appendicular Skeleton
Mrs. Halkuff Anatomy & Physiology

2 Vertebral Column Made up of 33 bones Cervical Vertebrae: First 7
Form the neck & support the head. C-1 is called the atlas as it allows the head to nod “yes”. C-2 is called the axis as it allows the head to shake “no”.

3 Thoracic Vertebrae: Second 12
Anchor the ribcage Larger than the cervical vertebrae Increase in size inferiorly. Lumbar Vertebrae: Third 5 Largest set of vertebrae Support weight Allow attachment of back muscles.

4 Vertebrae Body Vertebral Foramen Pedicle Lamina Spinous Process
Superior Articular Process Transverse Process


6 Sacrum & Coccyx Sacral Horns Medial Sacral Crest Dorsal Foramina

7 Sternum Manubrium Jugular Notch Clavicular Notch Body Xiphoid Process

8 Clavicle Makes up the shoulder girdle.
Connects the sternum to the scapula. Medial 2/3rd of shaft is convex anteriorly Lateral 1/3rd is flat & concave anteriorly. Helps to form two joints: Sternoclavicular Joint Acromioclavicular Joint

9 Clavicle Medial End Lateral End

10 Scapula Covers the 2nd – 7th ribs
Connects the clavicle to the humerus. Has a concave anterior surface & convex posterior surface.

11 Scapula Acromion Coracoid Process Scapular Notch Superior Border Spine
Vertebral Border Axillary Border Glenoid Cavity

12 Humerus Largest bone in the upper limb

13 Humerus Greater Tubercle Lesser Tubercle Intertubercular Groove
Deltoid Tuberosity Head Olecranon Fossa Medial Epicondyle Lateral Epicondyle Trochlea Capitulum

14 Radius Shorter of the two forearm bones Has circular radius

15 Radius Head Neck Radial Tuberosity Styloid Process

16 Ulna Longer of the two forearm bones Has “pipe wrench” appearance; or
“U” for “ulna” Olecranon Process Coronoid Process Radial Notch

17 Hand Phalanges (Proximal, Middle, Distal)
Each phalange is a miniature long bone. Wider at the base (proximal end) & smaller at the head (distal end). Thumb has 2 phalanges; all other digits have 3 phalanges.

18 Metacarpals Heads are the distal ends that articulate with the phalanges (knuckles). Shafts are concave on medial & lateral sides to allow for muscle attachment.

19 “Students Like The Professor To Teach Complex Hypotheses”
Carpals Wrist=“Carpus” 8 bones arranged in proximal & lateral rows. Proximal Row (Medial  Lateral) Scaphoid “Rowboat”, Lunate “Moon”, Triquetrum “3 cornered bone”, Pisiform “Pea” Distal Row (Medial  Lateral) Trapezium “Large Table”, Trapezoid “Little Table”, Hamate “Hook”, Capitate “Round Head” “Students Like The Professor To Teach Complex Hypotheses”
