Movement Of The Body Lecture 2 Flashcards
What is homeostasis definition
This is the tendency to resist change in order to maintain a stable relatively constant internal environment
What are the 2different types of homeostasis
Feedback - When the controlled variable moves too far from the set point and responses from the body attempt to move the variable back to “normal”
- E.g. If you get very cold, your body will reduce blood flow to the skin to reduce heat loss,
and you might also start shivering to produce heat.
Feed forward- Usually when there is an anticipation of an event that will alter a controlled variable, so you may do something to minimize the effect for example You look outside and see it is snowing. You know that if you go outside in shorts and a t- shirt, your temperature will drop, so you dress in warm clothing before you
What is anterior
Body parts that are closer to the front
What is posterior
Body parts the are closer to the back
What is superior
This is more of the upper part of the body
What is inferior
More down of the body
What is medial
Closer to the centre of the body
What is lateral
Closer to the outside of the body
That is proximal and distal
Proximal is closer to the origin while distal is more further away from the origin, for example this is mainly used only on limbs, so for the upper limb the elbow is proximal and the waist is distal
- wrist is proximal but knuckles are distal
What are the divisions of the body
Sagittl - this is dividing the body into left and right
Transverse - this is the cut from the middle
Coronal - this is a cut from back and front
Looking from the saggital plane what happens to flexsion and extension
Flexion decreases in angle
Extension increases in angle
What is dorsflextion
Putting the back on your foot on the ground
What is plantoflextion on foot
Tiptoes
What are 2 coronal movements
Abduction - movement away from the middle line
Addiction - movement towards the middle lime
That is inversion
Outside of your foot is in the ground while inside is up
