Today we are going to concentrate on the
joints in the human body.
JOINT- A place where two or more bones
meet.

Types of Joints
There are 3 main types of joint found in the body.
1. Fixed or Immoveable Joints
The bones at an immoveable joint cannot move -
they overlap or interlock, and are held together by
a tough fibre, e.g. the skull.
2. Slightly Moveable Joints
The bones at a slightly moveable joint can only move
a little - they are held together by strong straps
called ligaments and are joined by protective pads
known as cartilage, e.g. the ribs.
3. Freely Moveable Joints
At a freely moveable joint the bones move freely.
They are also known as synovial joints, and
are the largest group of joints found in the body,
e.g. the hips, shoulders and knees.

CLASSIFICATION OF JOINT BY
STRUCTURE
Fibrous: Have no cavity and are held together
by fibrous connective tissue – e.g. the sutures of
the skull bones
Cartilaginous: Also have no cavity. There is
cartilage between the bones of the joint. May be
found between the vertebrae of the spine
Synovial: Has a fluid filled cavity surrounded by
an articular capsule. The articulating surfaces are
covered in hyaline cartilage – e.g. the hinge joint
of the knee

5. Joints AQA AS / A Level Physical Education AS 5581 A 6581
CLASSIFICATION OF JOINT BY
MOVEMENT
Fibrous or synarthrosis: Does not allow any
movement, which makes more sense when you
know where in the body they occur, as they
supply protection – e.g. for the brain
Cartilaginous or amphiarthrosis: Allows only
limited movement
Synovial or diarthrosis: Is freely moving, as
much as the shape of the articulating surface will
allow.

Joints
Synovial Joints
• The articular capsule is a fibrous tissue encasing
the joint, forming a capsule
• The synovial membrane acts as a lining to the
joint capsule and secretes synovial fluid
• The articular/hyaline cartilage covers the ends of
the articulating bones
• Synovial fluid fills the joint capsule nourishes and
lubricates the articular cartilage

Joints
Synovial Joints
• Ligaments are white fibrous connective tissues
joining bone to bone, making the joint more stable
• Bursa is found where tendons are in contact with
bone. It forms a fluid filed sac between the tendon
and bone and helps reduce friction
• Articular discs of cartilage act as shock absorbers
• Pads of fat act as buffers to protect the bones form
wear and tear
