Today’s learning objectives

To know and understand:

• The structural and functional characteristics of a synovial joint

• The range of movement of synovial joints

Be able to:

• Identify the main muscles groups of the muscular system

Today’s learning objectives

• Complete the following columns of the movement analysis table for each of the joints....– Joint type– Articulating bones

Classification of Joints

• Fibrous • No movement• Most stable

• Cartilaginous• Little movement• Stable

• Synovial• Free movement• Least stable

Give an example for each type of joint

Mostly located in axial

skeleton

Mostly located in appendicular

skeleton

Synovial joints

Key features - NEW

• Bursa – A flattened fibrous sac lined with synovial fluid– Prevents friction at sites where ligaments, muscles, tendons and

bones might rub together

• Meniscus– White fibrocartilage that improves the fit between adjacent bone

ends– Make joint more stable and reduces wear and tear between joint

surfaces

• Pad of fat– Fatty pad that provides cushioning between the fibrous capsule

and a bone or muscle

Fibrous tissue encasing the joint Forming a capsule around the joint adds stability

C-shaped rims of fibrocartilage Acts as shock absorbers

A fluid that fills the joint capsuleNourishes and lubricates the articular cartilage

Lines the joint capsule Secretes synovial fluid

Covers the articulating surfaces of the bones

Prevents friction between the ends of bones

White fibrous connective tissue which attaches bone to bone

By securing the bones of joints together it adds significantly to joint stability

A sac filled with synovial fluid located between tendons/ligaments and bones

To reduce friction where tendons, ligaments, muscle or bones might rub together

Fatty tissue located between fibrous capsule and bone or muscle

Provides a cushion between the joint capsule and the bone/muscle

Wedges of fibrocartilage found between bones

Stabilises joint by improving the fit between bones. Reduces wear & tear

Specimen paper 2000

Explain the differences in flexibility measurements given for the shoulder joint and the hip joint in terms of….

(i) the structure of the joint;(ii) the difference between swimmers

and gymnasts.

Ball and socket jointsUse your understanding of the structure of the

shoulder and hip joints to explain which allows the greatest range of movement

The hip joint

Shoulder Joint

• The socket on the scapula (glenoid fossa) is small and shallow making the joint less stable

• The joint capsule is very loose (allowing seperation between the two bones) allowing more movement

• The head of the humerus is rounded but not as ball-like as the head of the femur, therefore it does not sit as deeply into the glenoid fossa

• The shoulder joint is stabilised by the rotator cuff muscles but these are not as strong as the muscles surrounding the hip.

• It is relatively easy to dislocate a shoulder

Hip joint

• The socket on the pelvis (acetabulum) is deep and cup-like in shape making the joint more stable

• A rim of fibrocartilage adds depth to the acetabulum, adding to stability

• The head of the femur is very spherical and fits snugly into the acetabulum

• The joint is supported by 5 strong ligaments

• The hip joint is surrounded by large muscle groups that aid stability, e.g. Gluteus maximus

• It is relatively difficult to dislocate the hip

Specimen paper 2000

(b) 1 mark for each of• The glenoid fossa at the shoulder joint is very shallow and allows

more movement than the hip• The acetabelum on the hip joint is quite deep giving more

stability and less movement.• The muscles and connective tissue surrounding the shoulder

joint are less restrictive than the hip as stability is not essential• Any relevant comment regarding the difference in technique for

swimmers or gymnasts• Any relevant comment concerning training for swimmers or

gymnasts

Types of movement

• What type of movements do we already know?

– Flexion– Extension– Abduction– Adduction– Rotation

Horizontal flexion

Horizontal extension

Lateral flexion

Circumduction

Pronation

Supination

Dosiflexion

Plantar flexion

Flexion & Extension

• Flexion – makes a body part move in a forwards direction from the anatomical position

• Extension – makes a body part move in a backwards direction from the anatomical position

• Except the knee joint! Flexion = lower leg moves backwards

Type of movementsFlexion

Extension

Abduction

Adduction

Rotation

Circumduction

Horizontal flexion

Horizontal extension

Lateral flexion

Pronation

Supination

Dorsiflexion

Plantar flexion

Memory aids

• Horizontal flexion/extension – Fingers are already pointing to the horizon

• Abduction – Being taken ‘away’ from or ‘abducted’

• Supination– Holding a bowl of soup ‘soupination’ = palms

upwards

• Plantar flexion – P for plantar and P for pointed feet

Practical task – on your feet….

Find a position in which all the major joints in your body are flexed
