Human Body Systems Lesson 18 Terms and Definitions Q: How does a chicken wing relate to a human arm? Bone Structure Tissue Types… 4 types of tissue 1. 2. 3. 4. Muscle Tissue Nervous Tissue Epithelial Tissue (skin) Connective Tissue Connective Tissues • Includes – Tendons – Ligaments – Bones Connective Tissue • Tendons – Connect muscle to bones. – silvery-white tissue at the ends of the muscles – Non-elastic = muscles contract and tendons pull the bones causing movement. Connective Tissue • Ligaments – Connect bones at joints . – Elastic to allow For movement http://www.quincymedgroup.com/adam/dochtml/graphics/images/en/12686.jpg Joints and Cartilage • Joints – Places where bones meet. • Cartilage – firm tissue at the ends of bones. – Glossy white, protects and lubricates bones at joints. http://www.bobs-webdb.com/images/joints1fixcs.jpg Skeletal Muscles • Muscles are connected to bones by tendons. • ONLY pull or contract. • Work in opposing pairs. http://leavingbio.net/Skeletal/The%20Skeleton%20and%20the%20Muscles_files/The%20Skeleton%20and%20the%20Muscles_files/image059.gif Videos • Discovery Education 1. The Human Body: Pushing the Limits Segments: 1. Bone: Strong and Flexible 2. Skeleton and Cartilage: Shock Absorption
