Types of Joints & Ligaments and Tendons

Types of JointsJoint: where two or more bones meet

Joints and Movement: Different joints have varying degrees of movement

Three types of joints-fibrous joints-cartilaginous joints-synovial joints

Fibrous JointsFibrous joints: Bones that are connected

together without gaps. Fibrous joints, movement: Not mobile

Cartilaginous JointCartilaginous joints: Bones

connected by a small cushion of cartilage. This cartilage acts as a shock absorber, protecting the joint from impact.

Cartilaginous joints and Movement: Restricted movement

Synovial Joints

Synovial joints: Joints where the surface of the bone is covered with a layer of slippery cartilage. Found in the arms and legs

Synovial joints and movement: Joints that move freely

Synovial Membrane: Found in the joining surface. Secretes a slippery fluids onto the surface of the joint

Types of Movement

Hinge A hinge joint allows extension and retraction of an appendage.

Found in: Elbow and knees

Types of Movement

Ball and Socket: A ball and socket joint allows for radial movement in almost any direction.

found in: hips and shoulders.

Types of Movement

Gliding In a gliding or plane joint bones slide past each other.

Found in: Midcarpal and midtarsal

Types of Movement

Saddle: A saddle joint allows movement back and forth and up and down (not rotation).

Found in: Where fingers connect to hand

Types of joints

Pivot: Pivot joints allow

rotation around an axis.

Found in: neck and forearms

Ligaments and Tendons

Ligaments: Connective tissue that joins bones to other bones.

Found in: Ankles, wrists, knees, and hands

Ligaments and Tendons

Ligaments: Connective tissue that joins bones to other bones.

Found in: Ankles, wrists, knees, and hands

Tendons: Connective tissue that joins bone to muscle.

Found in: Where ever muscle and bone connect.

Tendons

Brusae: Fluid filled sacs between bone and tendon.

Function of the brusae: Reduce the rubbing of the tendon on bone
