Explain The Division Of The Skeletal System Quiz

The Skeletal System is composed of bones, joints, cartilages, and ligaments. The incorrect answers do not belong to the skeletal system components.

The correct divisions of the Skeletal System are axial (consisting of the skull, rib cage, and vertebral column) and appendicular (consisting of the limbs and the girdles that attach them to the axial skeleton). The incorrect answers do not accurately represent the divisions of the skeletal system.

The human adult skeleton consists of 206 bones, including bones in the axial and appendicular skeleton.

The two basic types of bone tissue are Compact Bone and Spongy Bone. Compact bone is dense and forms the outer shell of bones, while Spongy bone is less dense and located at the ends of long bones and in the vertebrae.

Compact bone is dense and looks homogenous, without visible gaps or pores. It is strong and provides structure and support to the skeletal system.

Spongey Bone is composed of small, needle-like pieces of bone with many open spaces, making it less dense than compact bone. Cartilage is a different type of tissue found in the body, while marrow is the soft tissue found in the center of bones.

Bones are classified into long, short, flat, irregular, and sesamoid based on their shape and structure.

Long bones are typically longer than they are wide, have a shaft with enlarged ends called epiphyses, and consist mainly of compact bone tissue.

Short bones are typically cube-shaped, with equal lengths and widths. They predominantly consist of spongey bone, providing a balance between strength and flexibility. Examples of short bones include carpals in the wrist and tarsals in the ankle.

Irregular bones do not have a specific shape or classification like long, flat, or short bones. They have a unique shape, are usually connected to multiple other bones, and do not fit into traditional bone categories such as vertebrae or hip bones.

Sesamoid bones are typically small, rounded bones that are embedded within tendons near joints, such as the knee, wrists, and thumbs. They serve to protect tendons from excessive wear and tear during movement.

Long bones have a specific structure that includes articular cartilage, periosteum, and arteries. Nerves, ligaments, and veins are not part of the main components of a long bone's structure.

Long bones like the femur or humerus consist of the diaphysis which forms the shaft of the bone and is composed of compact bone tissue. The epiphysis forms the ends of the bone and mainly consists of spongy bone tissue.

Articular cartilage is specifically responsible for covering joint surfaces and reducing friction during movement.

The periosteum is the outer covering of the diaphysis of long bones and consists of fibrous connective tissue. It also covers joint surfaces to provide protection and support.

Long bones consist of distinct parts with specific functions, and it's important to understand the correct labeling of these parts for anatomical study purposes.

The incorrect answers do not accurately represent parts of compact bone. Compact bone is primarily composed of osteons and lamellae, with structures such as cartilage, marrow, and ligament being distinct components in the skeletal system.

Compact bone refers to dense bone tissue that forms the shaft of long bones (diaphysis) and is made up of cylindrical units called osteons. This type of bone provides strength and support to the skeletal system.

Spongey bone is also referred to as cancellous bone due to its porous nature and unique structure. It is different from compact bone and serves specific functions in the skeletal system.

Bone ossification can occur through either intramembranous or endochondral processes, each with unique characteristics in terms of bone formation.
