Question 2

What are the four major types of bones?

Answer 2

1. Long Bones
2. Short Bones

4. Irregular Bones

Question 3

Long Bones

Answer 3

Long Bones are found in the arms and legs including the humerus, femur, ulna radius, tibia, and fibula. They are longer than they are wide and have a shaft with two enlarged ends, called the proximal and distal ends. The shaft of the long bone is called the diaphysis and the enlarged end are called the epiphysis.

Question 4

Proximal and distal ends.

Answer 4

In the long bone, Proximal distal ends are composed of a shaft with two enlarged ends.The shaft of the long bone is called the diaphysis and the enlarged end are called the epiphysis.

Question 5

Irregular Bones are found in the spine and include the vertebrae. They have a variety of shaped and are not symmetrical.

Question 8

What is the composition of bones?

Answer 8

• Compact bone
• Spongy bone
• Cancellous bone
• Trabecular bone
• Bristol bone disease

Question 9

Compact bone

Answer 9

Compact bone is the hard outer layer of bone that provides protection and support. It makes up the shaft of long bones and the flat surfaces of there bones.

Question 10

Spongy bone

Answer 13

Results from a mutation in the gene that codes for collagen, which is a protein that makes up bone and tissue. This disease causes bones to be fragile and break easily.

Question 14

What is the relationship between the skeletal and Muscular systems?
