Hole’s Human Anatomy and Physiology Chapter 8 Joints of the Skeletal System Instructor: Quinn V. Bui, DC, MPH, MS Credit: 4 Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display. 8-1

2 Chapter 8 Joints of the Skeletal System
Articulations Junctions between bones _______________________________ _________________________ Permit parts of the skeleton to change shape during childbirth ____________________________________ muscle contraction 8-2

3 Classification of Joints
Fibrous Joints ____________________ tissues connect bones between bones in close contact synarthrotic ___________ amphiarthrotic ______________ diarthrotic freely movable Cartilaginous Joints _______________ or fibrocartilage connect bones Synovial Joints __________ allow free movement 8-3

4 Fibrous Joints 3 Types ____________ _________ ___________
______________ long fibers connect bones ________________ distal ends of tibia and fibula 8-4

5 Fibrous Joints Suture between flat bones ______________
thin layer of connective tissue connects bones Gomphosis cone-shaped bony process in a socket ____________ _____________ 8-5

6 Cartilaginous Joints 2 Types _______________ ____________
Synchondrosis bands of hyaline cartilage unite bones _____________ (temporary) between manubrium and first rib ______________ 8-6

7 Cartilaginous Joints Symphysis pad of fibrocartilage between bones
__________________ joint between bodies of vertebrae ____________________ 8-7

8 Synovial Joints ___________ joint cavity ________________
joint capsule synovial membrane bursae 8-8

9 Types of Synovial Joints
Ball-and-Socket Joint ______ _________ _____________ between metacarpals and phalanges 8-9

10 Types of Synovial Joints
Gliding Joint between ______ between ________ ___________ ________ between phalanges 8-10

11 Types of Synovial Joints
Pivot Joint between proximal ________ and ulna __________ between carpal and metacarpal of thumb 8-11

12 Types of Joint Movements
__________________ dorsiflexion/plantarflexion flexion/extension/_________________ 8-12

13 Types of Joint Movements
________________ supination/pronation 8-13

14 Types of Joint Movements
______________ protraction/retraction elevation/depression 8-14

15 Shoulder Joint _____________ head of humerus glenoid cavity of scapula
_________________ bursae ___________ prevent displacement very wide range of movement 8-15

16 Shoulder Joint 8-16

17 Elbow Joint ____________ __________ ____________________
trochlea of humerus trochlear notch of ulna __________ capitulum of humerus ____________________ many reinforcing ligaments stable joint 8-17

18 Elbow Joint 8-18

19 Hip Joint ________________ head of femur ______________
heavy joint capsule many reinforcing ligaments _____________ of movement than shoulder joint 8-19

20 Hip Joint 8-20

21 Knee Joint largest joint ______________
medial and lateral condyles of distal end of femur medial and lateral condyles of proximal end of tibia femur articulates anteriorly with patella ___________________ __________________________ strengthened by many ligaments and tendons menisci separate femur and tibia bursae 8-21

22 Knee Joint 8-22

23 Life-Span Changes Joint stiffness is an early sign of aging
________________ can prevent stiffness Fibrous joints first to strengthen over a lifetime Changes in symphysis joints of vertebral column diminish flexibility and decrease height ____________________________ 8-23

24 Clinical Application Joint Disorders Sprains
damage to cartilage, ligaments, or tendons associated with joints forceful twisting of joint Bursitis inflammation of a bursa overuse of a joint Arthritis inflamed, swollen, painful joints ____________________ ________________ _______ 8-24
