Saladin Anatomy And Physiology Quiz

Explanation
The skeleton does not provide storage. The main functions of the skeleton are to support the body, protect internal organs, and allow movement. Storage of minerals and fats is not a primary function of the skeleton.

Explanation
Bone is also known as osseous tissue because osseous refers specifically to bone tissue. It is the hard, dense, and rigid connective tissue that forms the structural framework of the body and provides support, protection, and mobility. Osseous tissue contains specialized cells called osteocytes, along with collagen fibers and mineral salts, which give bone its strength and resilience. The term osseous accurately describes the nature and composition of bone tissue, making it the correct answer.

Explanation
The given options include different types of bones, such as flat, long, and short. However, "wide" is not a recognized type of bone. Bones are generally classified based on their shape and function, and wide is not a commonly used classification for bones.

Explanation
The expanded heads of bones are known as epiphysis. The epiphysis is the rounded end of a long bone, which articulates with another bone to form a joint. It is composed of cancellous bone and contains red bone marrow, which is responsible for the production of blood cells. The epiphysis plays a crucial role in the growth and development of bones.

Explanation
Osteoblasts are bone forming cells. They are responsible for the synthesis and secretion of the organic matrix of bone, which eventually mineralizes and forms new bone tissue. Osteoblasts play a crucial role in bone development, growth, and repair. They are derived from mesenchymal stem cells and are found on the surface of bone. Through their activity, osteoblasts contribute to the overall strength and structure of the skeletal system.

Explanation
Ossification is the correct answer because it refers to the process of bone formation. During ossification, cartilage or fibrous tissue is replaced by bone tissue, resulting in the formation of bones. This process is essential for the development, growth, and repair of skeletal structures in the body. Fusion, reproduction, and crystallization are not accurate terms to describe the formation of bone.

Explanation
Mineral resorption is the process in which minerals, such as calcium, are removed from the bone tissue. This process involves the dissolution of the minerals, meaning they are broken down and absorbed by the body. This is an important process for maintaining the balance of minerals in the body and for remodeling of the bone tissue.

Explanation
Calcitriol is a form of vitamin D.
