Joints

Articulations

Where 2 or more bones

connect

Reason for Joints

Connect bonesoProvide SupportoMake them secure

Allow for movement in most cases

Hyoid only bone that doesn’t connect with another boneoAnchors tongue

3 Types of JointsClassified by how

much movement they allow

SynarthrosesConnective fibers

grow between the bones

Structurally Strong

Suture Line “show” jointo Skullo Pelvis

Fibrous Jointso Tib / Fibo Radius / Ulna

Teeth

No Movement

jointVertebral joints

o Allows for varied movement

o Absorb forceo Discs filled with a gel

Ribs to Sternum

Slight Movement

Diarthroses

Capable of many types of MovementsoSome just one movement (two directions)

• Knee - 2oSome joints capable of many directions

• Elbow - 4• Ankle – 6• Wrist – 7

Synovial Joints

Free Movement

Page 10: Joints Articulations Where 2 or more bones connect.

Structure of Synovial Joints

Joint Capsuleo Fits over the ends of two

bones like a sleeve

Ligamentso Connect two bones

together

Articular Cartilageo Cushion bone endso reduce friction

Synovial membraneo Lubricating fluid

Types of Diarthroses

Ball and Socketo Shoulder & Hip

Hingeo Elbow & Fingers

Pivoto Atlas/Axis (C1 & C2)o Radius/Ulna
