Dec 14, 2015
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.
