helps form a joint
A condyle differs from an epicondyle in that the condyle ____
large, irregularly-shaped projection
A trochanter is a _____
phalanges
All of the following (patella, phalanges, tarsals carpals) are short bones except ________
production of melanin
All the following are functions of the skeleton EXCEPT _____
patella
An example of a sesamoid bone is the _____
articulations
Bones of the skeleton are connected at junctions called _______
The bone treated with acid because the acid dissolves the calcium phosphate, making the bones less rigid and prone to deformation
In a child with rickets, the bones are prone to deformities caused by a lack of calcium, phosphate, or vitamin D. Which treated bone in Activity 2 most closely resembles the bones of a child with rickets? Why?
The bones store fat, red marrow, and calcium.
In addition to supporting and protecting the body, the skeleton provides this function as well.
yellow, red

T OR F Cartilage has a covering made of dense connective tissue called a periosteum.
medullary cavity
The ________ is the storage area for yellow marrow in an adult bone.
axial
The __________ skeleton consists of bones that surround the body's center of gravity.
central (Haversian) canal
The center of the osteon is called the ______
long
The femur is an example of a(n) __________ bone.
fibroblasts
The pain in the leg that is referred to as "shin splints" is often caused by microtears in the periosteum and perforating fibers. These tears lead to inflammation of the periosteum. Considering the type of tissue found in the periosteum, which cells do you think would be most involved in the repair process?
diaphysis
The shaft of a long bone is known as the _________
osteon
The structural unit of compact bone is the _____
fibrocartilage
The type of cartilage that has the greatest strength and is found in the knee joint and intervertebral discs is _____
hyaline
This is the most common type of skeletal cartilage.
hyaline
This type of cartilage attaches ribs to the sternum.
elastic
This type of cartilage supports the external ear and keeps it firm but flexible
irregular
Vertebrae belong to this category of bones.
hyaline, elastic, fibrocartilage

sternum
Which of the following bones belongs to the axial skeleton?
