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

false

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

What are the 3 types of skeletal cartilage?

sternum

Which of the following bone belongs to the axial skeleton and is a flat bone?

sternum

Which of the following bones belongs to the axial skeleton?
