Ligament
Tendon
Muscle
Cells, collagen fibers
and proteoglycals
Consists of type I
collagen
Made up of
myofibrils;
composed of
protein filaments
(actin and myosin)
Parallel, oblique or
Fibre
arrangement even spiral
Parallel errors of
tropocollagen
Unipennate,
multipennete or
fusiform patterns
Function
•Connects muscles to
bone
• Producing motion
and contributing to
joint stabilization.
Permit movement
and maintain
posture.
Microscopic
structure
•Connects bone to
bone
• Passively stabilizes
the joints
• Proprioceptive
function
•Soft
tissue injuries
cartilage
muscle
ligament
tendon
•Skeletal injuries (fractures)
 Tendons
 Acute/
overuse injuries
 Tendinosis/Tendinitis
 Tenosynovitis (inflammation/irritation)
 Avulsion
 Ligaments
acute trauma
 Total/ partial rupture
 Muscles
 Distension
 Direct
trauma resulting in contusion of the
muscle
 Inflammation
is a local response that
occurs in vascularized tissue in response
to loading of sufficient magnitude that it
results in cell damage.
 Begins
with bleeding and plasma
exudation
 Initiates clotting
 Forms a meshwork of fibrin, fibronectin
and collagen
 Last a few days
 Accumulation
of large numbers of
endothelial cells, myofibroblasts and
fibroblasts at the site of injury.
 Ingrowth of capillaries begin
 Lasts for a few weeks
 Establishes
the final tissue structure
through continuous remodelling of the
scar tissue.
 No. of macrophages is significantly
reduced and mature blood supply is
established
 Lasts several months
Sprain
Strain
A sprain is an injury to a
ligament. A ligament is a
thick, tough, fibrous
tissue that connects bones
together
A strain is an injury to a
muscle or tendon.
Muscles move your
skeleton in an amazing
variety of ways.

Three types of movements associated with muscles
movements. They are static, concentric and eccentric.
ACTION!
DEFINITON!
Static
Non-moving
position of a
muscle. The
length of the
muscle does not
change.
Concentric
Shortening of the
muscle.
Eccentric
Lengthening of
the muscle.
JUMPS!
HOW?
Standing Jump
Starts from a stationary semisquatted position, does not
preliminary employ a downward
phase and thus does not involve prestretching of muscles.
Countermovement Jump
Starts from an upright standing
position, makes a preliminary
downward movement, and then
extending it to jump vertically up off
the ground.
Drop Jump
Drop down from a specified height
and then jumps upwards.
 Myositis: a
type in which connective
tissue forms within the muscle.
 Ossificans: the
deposit of bone in muscle
tissue, causing pain and swelling.

 Andreas
uses countermovement jump
and suffered a sprain on the tendon.
 He
suffered tendinitis.
