The Articulated Skeleton Flashcards
What are long bones?
Long bones are hard, dense bones that provide strength, structure, and mobility
Have a shaft
Name examples of long bones
Humerus
Femur
Radias
Ulnar
What are short bones
Short bones are as wide as they are long
Their primary function is to provide support and stability with little to no movement
Name some examples of short bones
Carpals, Tarsals, Patella
What are he five types of bones?
Short Long Flat Irregular Sesamoid
What are bone foramina?
Holes where blood vessels / nerves enter or leave
or a cavity the bone encloses
What are the bumps present on bone surfaces?
Tubercles / tuberosities
Points are called spines or processes
What is the role of the bumps on bone surfaces?
Serve as attachment points for tendons and ligaments
What are the grooves seen on certain bones?
Grooves are formed where blood vessels, nerves or tendons lie close to the bone
a deeper hollow is a fossa
What are condyles?
Smooth part of bone which form joint surfaces
- either medial or lateral
What are epicondyles?
Smaller points on condyles, just outside the joint where ligaments are attached
What is the suprascapular notch?
The suprascapular notch (or scapular notch) is a notch in the superior border of the scapula (shoulder bone) , just medial to the base of the coracoid process
What is the role of the scapula?
Joins the humerus with the clavicle
Where are the greater and lesser tubercles located?
The greater tubercle of the humerus is situated lateral to the head of the humerus and posterolateral to the lesser tubercle
What are transverse processes?
Transverse process is a small bony projection off the right and left side of each vertebrae
- site of attachment for muscles and ligaments of the spine - point of articulation of the ribs (throacic spine)
