Title: MUSCLES AND MOVEMENT


1
MUSCLES AND MOVEMENT
To know the meaning of origin and insertion of
a variety of muscles To understand the different
muscular movements To be able to develop a mind
map on joints and movements.
2
STARTER
  • IN PAIRS IDENIFTY THE TYPE OF
  • MOVEMENTS OCCURING AT EACH JOINT.

3
The Origin and Insertion
  • When a muscle contracts, only one bone moves
    leaving the other stationary. The points at
    which the tendons are attached to the bone are
    known as the origin and the insertion.
  • The origin is where the tendon of the muscle
    joins the stationary bone(s).
  • The insertion is where the tendon of the muscle
    joins the moving bone(s).

Origin
The arm is being flexed.
Insertion
The radius and ulna are the moving bones-
INSERTION
The humerus and scapular are stationary bones-

Antagonistic Muscles
  • Skeletal muscles work across a joint and are
    attached to the bones by strong cords known as
    tendons.
  • They work in pairs, each contracting or relaxing
    in turn to create movement.
  • E.g Biceps brachii and triceps brachii known as
    ANTAGONISTIC
  • MUSCLE ACTION.
  • AS one muscle shortens the other one lengthens.

Movement of the armat the elbow

Flexion (Bending) of the Arm
  • The muscle doing the work (contracting) and
    creating the movement is called the agonist or
    prime mover.
  • The muscle which is relaxing and letting the
    movement take place is called the antagonist.

Antagonist (Triceps relax)
Agonist or Prime Mover (Biceps contract)
  • Other muscles support the prime mover (agonist)
    in creating movement and these are called
    synergists.
  • Fixtor-the muscle that allows the agonist to
    work, stabilising the origin.

36
TYPES OF MUSCULAR CONTRACTION
ISOTONIC- the muscle is moving while contracting,
it can be divided into concentric and eccentric
contractions
CONCENTRIC- contractions involve the muscle
shortening while contracting e.g biceps brachii
in elbow flexion
ECCENTRIC- contraction involves muscle
lengthening whilst contracting e.g. bicep brachii
in elbow extension
37
ISOMETRIC
Contractions occur when there is tension on the
muscle but NO movement E.G static contractions
occur when holding your weight in a stationary
position HANDSTAND
38
MUSCLE SHORTENING
MUSCLE LENGTHENING
39
ISOKINETIC
Contractions cause the muscle to shorten in
length and increase in tension whilst working at
a constant speed against a variable
resistance E.G. running on a treadmill ISOKINETI
C MEANS SAME SPEED
