Unit 4 Day Anatomy "No bird soars too high if he soars with his own wings." -William BlakeWilliam Blake
Today’s Agenda Objective 13 & 14 Notes on objectives 15 & 16 Match the joint with its description Types of joints Model types of joints
Objective 13: Define joint and articulation Joint = articulation = point where two bones meet.
Objective 14 Describe the criteria used to classify joints structurally and functionally.
Structural Classification Cartilaginous Joints Fibrous Joints Synovial
Functional Classification Synarthrotic- Immovable Amphiarthrotic- Slightly Movable Diarthrotic- Full Movable
Objective 15 Describe the general structure of fibrous joints and give examples of the three common types
Fibrous Joints Where bones are connected by fibrous tissue. No joint cavity is present. Amount of movement dependent on the length of the fibers.
Examples Sutures of the skull Filled with very short connective tissue Adulthood joint becomes ossified and fused together to one unit -- Synostoses
Example (con’t) Syndesmoses ligaments that connect the tibia and the fibula Gomphoses articulation between the tooth and bony alveolar socket
Practice – Fibrous Jt. 8.What is the difference in a suture and a synostoses? 9. What kind of joint holds a tooth in its bony socket?
Objective 16 Describe the general structure of cartilaginous joints and give examples of the two common types.
Cartilaginous Joints Bones of these joints are united by cartilage. No joint cavity is present.
Examples Synchondroses Costal Cartilages that connect the ribs to the sternum Symphyses Discs that form joints between the vertebra.
Practice – Cart. Jt. 10.What is the main difference between a fibrous joint and a cartilaginous joint? 11. Name two cartilaginous joint?
Diarthrotic Joints Fully mobile Aka – Synovial Joint Contain a space called the synovial cavity and articular cartilage covering the bones of the joint.
Ball and Socket Joint
Ellipsoid joint between scaphoid and lunate bones of the wrist
Saddle joint between trapezium of the carpus (wrist)

Joints Chapter 8. What is a joint? Defined as the site where two or more bones meet. Also called an “articulation” Joints allow our skeleton mobility.

what are joints? A joint is a place where two or more bones meet. There are several different types of joints, each producing different types and amounts.

8 Joints Objectives: Joints Define joint or articulation. Classify joints structurally and functionally. Describe the general structure of fibrous joints.
JOINTS Functions of joints Hold bones together Allow for mobility Ways joints are classified Functionally (how much they can move) Structurally (what separates.
Chapter 7- Joints. -A point of contact between bones -Articulation -Functions: 1) Hold bones together 2) Allow for mobility -Classification: -Structurally.
General Classification Synarthroses and Amphiarthroses.
Joints. Now that we know all of the bones we need to look at the joints of the skeleton Joints, also called articulations, have two main functions They.
Suzanne D'Anna1 Joints or Articulations. Suzanne D'Anna2 Structural Classification l Based on: - presence or absence of a joint cavity between bones -
+ Bone Markings and Joints. + Do Now Quiz Corrections Questions pg. 173.
Classification and mobility. Fibrous - no joint cavity, joined by fibrous tissue, mobility depends on the length of the tissue, most are immovable
Bio& 241 A&P 1 Unit 2 / Lecture 3. Functional classification of joints (based on degree of movement permitted within the joint) Synarthrosis: Immovable.
Articulations (joints) –Hold bones together –Allow body movements Structurally are 3 types: –Fibrous, cartilaginous, synovial Functionally are 3 types:
Joints Come in Many Types. Joints (Articulations) Functions of joints Classifying Joints: Functional or Structural Naming Movements of Bones Around Joints.
Chapter 9 Joints. Joint Classification Functional Classification Synarthrosis – immovable Amphiarthrosis – slightly movable Diarthrosis – freely movable.
Ex 13. Articulations- joints - hold bones together - Allows for movement Classified based on - Structure - functionality.
JOINTS. OBJECTIVES Be able to classify the joints of the body both structurally and functionally Be able to classify the joints of the body both structurally.
CHAPTER 9 “Joints” COMMON COURSE OBJECTIVES: 1. Joints: Structural and functional classification 2. Structure of a typical synovial joint 3. Types of synovial.
Joints and their classification bony joints fibrous joints cartilaginous joints Synovial joints 7-1.
Ch 9 Joints- Articulations -between bones, cartilage and bones, or teeth and bones.
Daily Quiz Where is the femur found? What is another name for the mandible? Where is the humerus found? Describe a comminuted bone fracture. What is the.
Skeletal System Joint Notes Joints perform two functions Hold bones together Allow rigid skeleton some flexibility so movement can occur.
Joints Articulations. Joint Classifications Structural Classification Fibrous Cartilaginous Synovial Functional Classification (Type of Movement) Synarthrosis.
Cartilaginous & Fibrous. Also called articulation Place where two or more bones meet.
Essentials of Human Anatomy Essentials of Human Anatomy The Skeletal System 2.
Joints Intro/Types of Joints. Joints 1. With one exception (the hyoid bone in the neck) every bone forms a joint with at least one other bone. 2. Joints,
Joints Joints (articulations), the sites where two or more bones meet, have two fundamental functions: – Give skeleton mobility – Hold skeleton together.
Chap 8 Joints Pgs Learning Objectives: 1.Explain an articulation (joint). 2.Classify joints based on structure and function. Describe their characteristics.
Joints (a.k.a. Articulations). I. Introduction A.Joint 1. articulation 1. Also called an articulation 2. Defined: A joint is a point of contact between.
THE SKELETAL JOINTS. JOINTS Joints are where two or more bones articulate (move). Joints are classified according to how much movement they allow. 1.
JOINTS. JOINTS Is an articulation, the place of union or junction between two or more bones or parts of bones of the skeleton -They show a variety of.
Articulations Chapter 9. Introduction Skeleton composition –Many bones joined together (articulated) Articulation –Joints Advantages and disadvantages.
Joints. Joints (articulation) Defined: A point of contact between bones, between cartilage and bones, or between teeth and bones. – When two bones articulate.
ARTICULATIONS Joints between bones Hold bones firmly to each other Permit movement Classified by degree of movement (range of motion) and type of substance.
1 Human Anatomy, First Edition McKinley & O'Loughlin Chapter 9 Lecture Outline: Articulations.
Joint Structure. Classification of Joints Fibrous (synarthroses): lacks a joint cavity and the articulating bones are held very closely together by fibrous.
Ch. 9 Joints. Articulation- A point of contact between two bones or between a bone and cartilage –Can produce a wide variety of motions –Arthrology: The.
