Male v. Female Skeleton Male larger hip bones more narrow more bone mass Female wider hip bones angle at symphysis pubis is greater less bone mass
Types of Joints Fibrous (immovable) sutures Cartilaginous (slightly movable) symphysis pubis between vertebrae Between ribs and vertebrae Connected with disks of fibrocartilage Synovial (movable)
Types of Joints - Synovial Covered with hyaline cartilage Bursae Fluid filled sacs b/w skin and processes
Types of Joints - Synovial Ball and socket Shoulder and hip Highly movable joint Allow movement in all directions Condyloid Metacarpals and phalanges Metatarsals and phalanges
Types of Joints - Synovial Gliding (sliding) Wrist and ankle Allows bones to slide in all directions Hinge Elbow Knee Allows bones to move back and forth
Types of Joints - Synovial Pivot Radius and ulna Saddle Thumb
Arthritis Inflamed, swollen joints Osteoarthritis Most common; old age Articular cartilage wears down
Arthritis Rheumatoid Autoimmune disorder Cartilage replaced by bone Very disfiguring
Arthritis Infectious/Acute Bacterial infection Lyme disease Gouty Result of uric acid being deposited b/c kidneys are not properly filtering Deposited in great toe first
Additional Disorders Rickets Soft bone condition in children Lack of calcium and/or vitamin D Osteomyelitis Acute or chronic bone infection Commonly caused by bacteria (at times – fungi)
Flexion - Extension decrease - increase angle Abduction - Adduction away - toward midline Rotation around an axis Pronation - Supination palm down -palm up Elevation - Depression raising - lowering
Moving a part around an axis Rotation. Bending the head back beyond the upright position is called ______ Hyperextension.
CHAPTER 7 Joints. articulations Joints (or articulations) Where two or more bones meet Functions: movement, hold skeleton together Classified by structure.
Joints & Movements.
Joint Anatomy Connected to another bone Hold skeleton together Allow flexibility.
Joints. What is an articulation? They are joints and occur wherever two bones meet.
Classified by: Structure (composition) Function (range of motion)
Joints. Fibrous joints Joints that are in close contact with one another. In the skull, these are called sutures.
Joints The area where two bones are attached for the purpose of permitting body parts to move. A joint is usually formed of fibrous connective tissue and.

Joints and Movements of the Body
Classification and mobility. Fibrous - no joint cavity, joined by fibrous tissue, mobility depends on the length of the tissue, most are immovable
Articulations. Articulations (Joints) Articulations – wherever 2 bones meet Classified by function –Synarthrosis (Immovable) –Amphiarthrosis (slightly.
Joints Articulations of bones Functions of joints
Ch. 8 Warm-Up 1.What is another name for joints? 2.What are the 2 main functions of joints? 3.What do you think are the most common joint injuries?
Articulations and Movement. Articulations or Joints Articulation or Joint –Place where two bones come together –Freely movable to limited to no apparent.
JOINTS IN THE SKELETAL SYSTEM. What is a Joint? The area where two or more bones articulate (move). Joints give structure and flexibility to the skeleton.
Joints. Fixed (Fibrous joints) No movement occurs between the bones involved. Held in place by fibrous connective tissue On impact bone fracture rather.
Functions of Bones 1. Gives the body its shape 2. Support of the body’s weight 3. Protection of soft organs 4. Movement due to attached skeletal muscles.
Essentials of Human Anatomy The Skeletal System 2
ARTICULATIONS Joints between bones Hold bones firmly to each other Permit movement Classified by degree of movement (range of motion) and type of substance.
AS Level Anatomy and Physiology
Chapter 8Joints. Joints Also called articulations; place where two or more bones meet Function- Hold skeleton together and give it mobility.
Articulations. Chapter 11 Joints Joints b) Fibrous Joints 1) connections between adjacent bones 2) syndesmoses to gomphoses 3) ex.suture c) Cartilagenous.
8-1 Chapter 09 Lecture *. 8-2 JOINT DAY 8-3 Articulations or Joints Articulation or Joint –Place where two bones come together –Freely movable to limited.
December 9, 2014 Objective: To describe how joints function and to differentiate between types of joints Journal: Have you or someone you know ever.
Chapter 9 Articulations.
Honors Anatomy & Physiology Chapter 8. JOINTS aka Articulations 2 Functions: 1. Hold Bones Together 2. Allows otherwise rigid skeleton to have some.
JOINTS Allie Moyer & Kayla Jones. WHAT ARE THEY? o Joints are where two or more bones meet and are made up of a number of different parts that all work.
The Appendicular Skeleton
Joints AKA “articulations” – functional junctions between bones Functions: –Bind parts of the skeletal system –Make bone growth possible –Permit parts.

JOINTS OF THE SKELETAL SYSTEM. FUNCTIONS OF JOINTS Bind parts of the skeletal system Allow bone growth Allow growth of the brain Allow changes in shape.
Joints of the Skeletal System
1 Kinesiology. Daily Objectives Content Objectives Build a foundational knowledge of the articular system. Understand the Three classifications.
Joints A joint is the site of meeting of two or more bones. Joints are classified into three types (depending on the material that hold the articular bones.
Joints A joint, or articulation, is the place where two bones come together. Fibrous- Immovable; connect bones, no movement. (skull and pelvis). Cartilaginous-
