Chapter 6.1: Functions of the Skeletal System

  1. Components of the Skeletal System:

    • Bones
    • Cartilage
    • Connective Tissue (Ligaments and Tendons)

  2. Why are bones considered organs?

    • Bones are classified as organs due to their complexity and their role in performing vital functions necessary for life.
    • They serve as the support structure of the body and are composed of multiple tissues including:
      • Blood
      • Simple Squamous Epithelium
      • Nervous Tissue
      • Cartilage

  3. Main Functions of the Skeletal System:

    • 1) Supports the body
    • 2) Facilitates movement
    • 3) Protects internal organs
    • 4) Produces blood cells
    • 5) Stores and releases minerals and fat
    • 6) Provides leverage for movement

Chapter 6.2: Bone Classification

  1. Definitions of Bone Types:
    • a. Long Bone:
      • Characteristics: A cylindrical shape, longer than it is wide.
      • Locations: Found in the arms, legs, fingers, and toes.
      • Function: Operates as levers, facilitating movement when muscles contract.
    • b. Short Bone:
      • Characteristics: Cube-like shape; equal in length, width, and thickness.
      • Locations: Found in the carpals of the wrists and tarsals of the ankles.
      • Function: Provides stability and support, with some limited motion.
    • c. Flat Bone:
      • Characteristics: Typically thin, often with a curved structure.
      • Locations: Includes the cranial bones (skull), scapulae (shoulder blades), sternum (breastbone), and ribs.
      • Function: Acts as points of attachment for muscles and helps protect internal organs.
    • d. Irregular Bone:
      • Characteristics: Bones that do not have easily characterized shapes, making them hard to classify.
      • Locations: Examples include vertebrae, which support the spinal cord and protect it from compressive forces, and many facial bones (especially those containing sinuses).

Chapter 6.3: Bone Structure

  1. Membrane Lining the Interior Cavity of Long Bone:
    • The membrane that lines the interior cavity of long bones is called the endosteum.
