Session One: Introduction to movement Flashcards
(40 cards)
The anatomical position
Standing upright, arms at sides, palms are facing forward, thumbs to side and feet together.
Anterior
Front of the body. e.g lips to teeth
Posterior
The back of the body. e.g heel to toe
Distal
(Distant). Further away from where the arm or leg inserts itself from the body.
Proximal
(Proximity). Closer to the where the arm or leg insures itself from the body.
Midline
Centre of the body.
Medial
Closer to the midline.
Lateral
Further away from the body.
Superior
Above or towards the head.
Inferior
Below or towards the head
Body Planes
Mid Sagittal
Frontal plane
Transerve plan
Mid Sagittal
midline
Frontal Plane
Divides the body into anterior and posterior.
Transerve Plane
Divides the body into inferior and superior.
How do muscles move joints?
Muscles are attached to bones and create tension when pulling to move joints.
Isometric
Two types-> concentric and ecceentric
Concentric
The muscle shortens. Resisting Gravity
Eccentric
The muscle lengthens. The muscle controls the movement against an external applied force (Often assisted by gravity)
Isometric
Static muscle work the muscle work the muscle to stay the same and maintain the limb in a position. Resists gravity.
Antagonists
Are muscles that oppose this action and help control the extent and speed of movement. (relaxed)
Primer mover/s or Agonist
When a muscle (or groups of muscles) contracts to produce a movement. (concentrated)
Types of Muscles
Cardiac muscle = This is a heart muscle
Skeletal muscle = The tissue forms the wall of blood vessels and hollow organ
Smooth muscle = This is the muscle that is attached to bone and produces movement at joints.
Flexion
This is the movement that deceases of the angle between the joints.
Extention
This is the movement that increases the angle between to joints.
