3. Locate and identify the bones and the
major features of the bones that compose
the skull, vertebral column, thoracic cage,
pectoral girdle, upper limb, pelvic girdle,
and lower limb.
4. Classify joints according to the type of
tissue binding the bones together,
describe their characteristics, and name
an example of each.

TISSUES IN THE BONE
Copyright © 2009 Republic
Polytechnic
Skeletal Tissue
• 2 types
– Cartilage
– Bone
• Cartilage
– firm, smooth, avascular
– consists
• chondrocytes in
lacunae
• chondrotin matrix
• collagen fibres
• elastic fibres
Copyright © 2009 Republic
Polytechnic
Cartilage
• 3 types
• Hyaline cartilage
– solid matrix
– chondrocyte aggregates
– collagen fibres
– found in:
• articular surfaces
• airways
• sternal ends of ribs
Copyright © 2009 Republic
Polytechnic
Bone
• Composed of
– matrix
– cells
– collagen
fibres
– salts
• 2 forms
– spongy/cance
llous
• filled with
holes
– hard/compact
• dense

FEATURES OF THE BONE
Copyright © 2009 Republic
Polytechnic
Classification of Bones
• 5 types
• Long bone
– longer than wide
– e.g. humerus
Copyright © 2009 Republic
Polytechnic
Classification of Bones
• Short bone
– short, cubed
– e.g. navicular
Copyright © 2009 Republic
Polytechnic
Classification of Bones
• Flat bone
– broad, smooth
surface
– e.g. scapula
Copyright © 2009 Republic
Polytechnic
Classification of Bones
• Sesamoid bone
– located within
tendon
– e.g. patella

SYNOVIAL JOINTS
Copyright © 2009 Republic
Polytechnic
Synovial Joints
• Identify and list the different types of
synovial joints in the body
Copyright © 2009 Republic
Polytechnic
Types of Synovial Joints
• 6 types
• Gliding
– one bony surface
slides over
another
– minimal
movement
– e.g. facet joint

Republic Polytechnic
Types of Synovial Joints
• Hinge
– one convex surface
slides over another
concave surface
– hinge movement in
one plane about one
axis
– allows flexion/
extension
– e.g. elbow

Republic Polytechnic
Types of Synovial Joints
• Ball and Socket
– movement in 3
planes about 3 axes
– types
• flexion/extension
• internal/external
rotation
• abduction/adducti
on
• circumduction
– e.g. shoulder, hip

Ball-and-socket Joint
Types of Synovial Joints
• Condyloid/Ellipsoidal
– movement in 2 planes
– types
• flexion/extension
• abduction/adduction
– e.g. wrist
Copyright © 2009 Republic
Polytechnic
Types of Synovial Joints
• Pivot
– rotation in one
plane about one
axis
– e.g. atlas/axis
Copyright © 2009 Republic

Pivot Joint
Republic Polytechnic
Types of Synovial Joints
• Saddle
– principal movement
in one plane about
one axis
– limited amount of
rotation/sliding
– e.g. thumb (MCP
joint)

Functional anatomy
• Practical session of the different types of
movement of the body
Copyright © 2009 Republic
Polytechnic
Types of Movement
• Rotation
– around a long axis
– external rotation
– internal rotation
Copyright © 2009 Republic

• Circumduction
– circumscribing a
conical area with a
combination of:
•
•
•
•
flexion
extension
abduction
