Chp 6 Flashcards
What are the functions of cartilage?
Cartilage provides support, flexibility, and cushioning in joints.
What is the function of hyaline cartilage?
Hyaline cartilage provides smooth surfaces for joint movement and flexibility.
Where is hyaline cartilage distributed?
Hyaline cartilage is found in the nose, trachea, and at the ends of long bones.
What is the function of fibrocartilage?
Fibrocartilage provides tensile strength and absorbs compressive shock.
Where is fibrocartilage distributed?
Fibrocartilage is found in intervertebral discs and the pubic symphysis.
What is the function of elastic cartilage?
Elastic cartilage maintains shape while allowing flexibility.
Where is elastic cartilage distributed?
Elastic cartilage is found in the ear and the epiglottis.
What are the functions of bone?
Bone provides structure, protection, and facilitates movement.
What are the characteristics of long bones?
Long bones are longer than they are wide and have a shaft with two ends.
What are the characteristics of short bones?
Short bones are roughly cube-shaped and provide stability with little movement.
What are the characteristics of flat bones?
Flat bones are thin and flat, providing protection and a surface for muscle attachment.
What are the characteristics of irregular bones?
Irregular bones have complex shapes that do not fit into other categories.
What is the gross anatomy of a long bone?
A long bone consists of a diaphysis (shaft) and epiphyses (ends), with a medullary cavity.
What are the cells of bone connective tissue?
The main cells are osteoblasts (build bone), osteocytes (maintain bone), and osteoclasts (break down bone).
What is the microscopic anatomy of compact bone?
Compact bone is dense and structured in osteons, providing strength.
What is the microscopic anatomy of spongy bone?
Spongy bone is lighter and consists of trabeculae, providing support and flexibility.
What are the anatomic terms that describe the surface features of bone?
Surface features include processes, depressions, and openings.
