What Are The Divisions Of The Ribs?

The ribs are divided into three groups, called true ribs, false ribs, and floating ribs. The top seven pairs of ribs are true ribs. They are attached by cartilage directly to the sternum. The next three pairs of ribs are false ribs.

Where is the axial division?

Axial and Appendicular Skeleton The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. It consists of the skull, vertebral column (including the sacrum and coccyx), and the thoracic cage, formed by the ribs and sternum.

What are the two main division of the appendicular skeleton?

The bones of the appendicular skeleton are divided into two groups: the bones that are located within the limbs themselves, and the girdle bones that attach the limbs to the axial skeleton.

What are the 2 divisions of our skeletal system?

The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.

What are the 2 types of bone tissue?

There are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together. There are three types of cells that contribute to bone homeostasis.

What are the two main division of the trunk or body?

The Axial Skeleton The skeleton is subdivided into two major divisions—the axial and appendicular.

How many divisions are in the body?

The body is composed of ten major systems: Skeletal, Muscular, Nervous, Cardiovascular, Lymphatic, Respiratory, Digestive, Endocrine, Urinary, and Reproductive. The front of the head, where the eyes, ears, nose and mouth are located, is called the face.

What are the 2 divisions of bones?

The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton.

Where is the bone tissue found?

The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels.

What are the two major divisions of the skeleton?

The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.

Which is a specialized part of the skeletal system?

The lower portion of the appendicular skeleton is specialized for stability during walking or running. In contrast, the upper portion of the appendicular skeleton has greater mobility and ranges of motion, features that allow you to lift and carry objects. The bones of the appendicular skeleton are covered in a separate chapter. 1.

How many ribs are in the thoracic cage?

The thoracic cage includes 12 pairs of ribs, and the sternum, the flattened bone of the anterior chest. Figure 7.1.1 – Axial and Appendicular Skeleton: The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body.

How many bones are in the skeletal system?

The skeletal system includes all of the bones, cartilages, and ligaments of the body that support and give shape to the body and body structures, whereas the skeleton consists of the bones of the body. For adults, there are 206 named bones in the skeleton.
