Anatomy & Physiology 1 Lab Chapter (6, 8, 9) Quiz

Interstitial growth in cartilage refers to the expansion of cartilage from within by the division and secretion of new matrix by chondrocytes within the lacunae. This process allows the cartilage to grow and increase in size.

Cartilage growth ends at adolescence when the skeleton stops growing. Cartilage is a type of connective tissue that serves as a cushion between bones and provides structural support.

Calcium salt deposit causes cartilage to harden and become calcified, a process that can occur during normal bone growth in youth or during old age. It's important to note that calcified cartilage is not the same as bone tissue.

Bones play a crucial role in the overall function of the human body by providing support, protection, aiding in movement, storing minerals and growth factors, producing blood cells, storing triglycerides, and hormon production. The incorrect answers provided do not align with the primary functions of bone.

Hematopoiesis refers to blood cell formation, while osteocalcin is a hormone produced by bone tissue.

The skeleton is divided into axial and appendicular divisions. The axial division consists of the skull, vertebral column, and rib cage, serving to protect, support, and carry the body. The appendicular division includes the bones of the upper and lower limbs, aiding in movement and manipulation of the environment.

Bones are classified based on their location in the body and their shape, which helps in identifying their function and structure.

Bones are considered organs because they are complex structures composed of various tissues that work together to serve different functions in the body.

Bone structure can be categorized into three levels: gross, which refers to the overall structure visible to the naked eye; microscopic, which involves examining bone tissue at a cellular level; and chemical, which involves studying the composition of bone at a molecular level.

The correct answer describes the unique characteristics of compact bone, which is dense, outer layer present in all bones and appears smooth and solid. The incorrect answers provide false information about compact bone to differentiate them from the correct answer.

Spongy bone is unique in its structure and location within bones. It is not found on the surface of bone structures, it is porous and honeycomb-like in appearance, and it does contain red or yellow bone marrow in its open spaces.

Long bones are covered by two types of connective tissue membranes, the periosteum which covers the outer surface of the bone and the endosteum which lines the inner surface.

The endosteum is a delicate membrane that covers the internal bone surfaces, contains osteogenic cells, and plays a role in bone remodeling and repair.

During development, the skeleton starts off as cartilage and fibrous membranes before being replaced by bone, providing flexibility and aiding in mitosis. Muscle tissue, blood vessels, and ligaments are not the main components of the developing skeleton.

Skeletal cartilage is made up of different cartilage tissues that are specialized for various locations and functions in the body. It is not made of bones, muscles, or skin.

Cartilage tissue is made up of water, providing its elasticity, and it is avascular, meaning it does not have blood vessels.

Cartilage tissue is surrounded by the perichondrium, which is a layer of dense irregular connective tissue providing support and nourishment to the cartilage cells.

The perichondrium plays a crucial role in supporting and nourishing cartilage tissue by surrounding it like a girdle, aiding in resisting outward expansion, and containing blood vessels for nutrient delivery. The incorrect answers do not accurately describe the function of the perichondrium.

Chondrocytes are the specialized cells responsible for producing and maintaining the extracellular matrix of cartilage. Fibroblasts are found in connective tissue, osteoblasts are involved in bone formation, and adipocytes are fat cells.

Cartilage tissue is classified into three main types based on the composition of the matrix and the types of fibers present in it. These types are hyaline cartilage, elastic cartilage, and fibrocartilage.

Hyaline cartilage is a type of cartilage that provides support, flexibility, and resilience. It is the most abundant skeletal cartilage and has fine collagen fibers only in its matrix, which are not visible to the naked eye.

Skeletal hyaline cartilage includes specific types of cartilage that serve different functions in the body, such as articulation, connection, structural support, and protection of various organs and tissues.

Elastic cartilage is distinct from hyaline cartilage due to its elastic fibers, providing flexibility and resilience. It is specifically located in the external ear and epiglottis, serving unique functions in these areas.

Cartilage growth can occur through appositional growth, which involves the addition of new chondrocytes on the surface, or interstitial growth, which involves the division of existing chondrocytes within the cartilage matrix.

Appositional growth refers specifically to the growth of cartilage by adding new layers of matrix onto the existing cartilage surface, as described in the correct answer.
