Study Notes
Functions of the Skeletal System
- Provides support and protection for the body
- Allows for movement through the attachment of muscles
- Produces blood cells through the bone marrow
- Stores minerals such as calcium and phosphorus
- Maintains pH balance by storing and releasing alkaline salts
Types of Bones
- Long bones: characterized by a shaft (diaphysis) and two ends (epiphyses); examples include the femur and humerus
- Short bones: cube-shaped bones that provide support and stability; examples include the carpals and tarsals
- Flat bones: thin bones that provide protection and support; examples include the ribs and sternum
- Irregular bones: bones that do not fit into any other category; examples include the vertebrae and pelvis
- Sesamoid bones: small bones embedded within tendons; examples include the patella
Bone Structure
- Compact bone: dense, compact bone tissue that makes up the outer layer of bones
- Cancellous bone: spongy, porous bone tissue that makes up the inner layer of bones
- Bone marrow: the spongy tissue that fills the cavities of bones and produces blood cells
- Periosteum: the outermost layer of bone that covers the surface of bones
- Endosteum: the innermost layer of bone that lines the bone marrow cavity
Bone Development and Growth
- Ossification: the process of bone formation
- Endochondral ossification: the process of bone formation through the replacement of cartilage with bone tissue
- Intramembranous ossification: the process of bone formation through the formation of bone tissue from membranes
Bone Remodeling
- Resorption: the process of bone breakdown and removal
- Formation: the process of new bone tissue formation
- Osteoclasts: cells responsible for bone resorption
- Osteoblasts: cells responsible for bone formation
This quiz covers the functions of the skeletal system, types of bones, bone structure, bone development and growth, and bone remodeling. It includes topics such as ossification, bone resorption, and bone formation.
