This is the first of several lessons dealing with the various systems of the human body.
and expect that you will use the methods of associative learning that you have studied in the earlier
lessons of this course as a tool to help you acquire mastery of this new material.
In this lesson you will learn the names of some of the more important bones of the human skeleton
using the associative tactics presented earlier in the program.
At this point, we hope that you have
discarded as inefficient the learning method sometimes called "rote memorization."
will give you not only an understanding of where certain bones are located, but when possible, an
etymological explanation of the word as well.
The word cranium comes from the Greek word kranion
, a word meaning "head" and is also
related to ker
from which the word cere
bellum is derived.
is related to keras (Latin, cornu
meaning "horn," since the horn of an animal is at the top of the head. The cranium, commonly referred

, the diminutive form of mala
meaning "jaw" or "cheek."
Commonly known as the collarbone, this word comes from the Latin clavicula
, meaning "a
little key" or "door bolt."
This is the diminutive of the base form clavis
("key") which is derived from
the Greek word kleis
also meaning "key."
Clavicle is applied to the bone from its shape.
Commonly called the shoulder-blade, this word comes from the Latin noun scapulae
This bone is located in the upper arm between the scapula and the ulna (the larger bone of
The word humerus is derived from the Latin noun humerus
meaning the "upper arm,
shoulder," and is related to the Greek omos
, also meaning "shoulder."
It is not a funny bone and
should certainly be taken seriously.
The inner and larger bone of the forearm, the name is derived from the Latin noun ulna
meaning "elbow, arm."

From the Latin word radius
meaning "ray." The radius is the shorter bone of the arm.
