Joints of the Body

Page 2: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Terminology:• Articulations – points of contact of joints

between 2 connected bones

• Tendon – attach muscle to bone• Ligament – attach bone to bone

Page 3: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Sternoclavicular Joint

• Connects the sternum & clavicle• Only joint connecting the pectoral girdle to

axial skeleton• Strengthened by intracapsular disc & extrinsic

muscles

Page 4: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Acromioclavicular Joint

• Unites lateral end of clavicle with acromion process of the scapula

• Shoulder separations often occur here

Glenohumeral Joint

• Connects upper limb & scapula• Multi-axial joint• Wide range of movement lack of stability

Elbow Joint• Humero-ulnar Joint– Medial– Between trochlea of the

humerus & olecranon process of ulna

• Humero-radial Joint– Lateral– Between capitulum of

humerus & head of radius• Radio-ulnar Joint– Between radius & ulna

Page 7: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Radio-Carpal Joint

• Between distal end of radius & carpals• Movement: flexion-extension & adduction-

abduction

Page 8: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Intercarpal Joint (Hand)

• Between bones of the carpals• Gliding joints

Page 9: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Carpometacarpal Joint

• Between carpals & metacarpals

• Characteristics of carpometacarpal joint of the thumb allows the range of movement necessary for opposition

Page 10: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Metacarpophalangeal Joint

• Between metacarpals & phalanges• “Knuckles”• Movements: flexion-extension & adduction-

abduction

Page 11: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Interphalangeal Joint

• Between the phalanges• Movement: Flexion-extension

Page 12: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Hip Joint

• Between head of femur & acetabulum of the hip bone

• Ball & socket joint• Movement: flexion-extension, adduction-

abduction & circumduction• Hip joint is very stable– Deepened socket– Intrinsic & extrinsic ligaments

Page 13: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Knee (Tibiofemoral) Joint

• Incredible range of movement• Flexion-extension• Relatively stable– Menisci• Shock-absorbing fibrocartilaginous discs

– Anterior & posterior cruciate ligaments• Centre of the joint

– Lateral & medial collateral ligaments• Extending from sides of the femur to tibia & fibula

Ligaments of the Knee

• Anterior Cruciate Ligament (ACL)– Prevents anterior movement of the tibia– Attaches medial & anterior to tibia– Attaches lateral & posterior to femur

• Posterior Cruciate Ligament (PCL)– Prevents posterior movement of the tibia– Attaches lateral & posterior to tibia– Attaches medial & anterior to femur

• Medial Collateral Ligament (MCL)– Medial stability– Attaches on tibia & medial side of femur

• Lateral Collateral Ligament (LCL)– Lateral stability– Attaches on fibula & lateral side of femur

Most common injury to ACL & MCL

Ankle (talocrural) Joint

• Involves several bones:– Medial & lateral malleoli of the tibia & fibula– Head of talus– Calcaneus

Page 21: Joints of the Body. Terminology: Articulations – points of contact of joints between 2 connected bones Tendon – attach muscle to bone Ligament – attach.

Foot & Toes Joints

• Joints between tarsals, metatarsals & phalanges:– Tarsometatarsal– Metatarsophalangeal– Interphalangeal• Strengthened by plantar ligaments

which air in maintaining the arch of the foot
