anatomy and physiology Flashcards
(43 cards)
long bones
levers responsible for creating gross movements
short bones
desgined to bare a lot of weight
designed for finer movement
absorbs stress of running and jumping
flat bones
protects vital organs
large suface area for muscle attachement
support
keep us upright and everything in place
protection
protect vital organs
Structural Shape
femur,tibia,fibula determine our height
bones provide something for the muscles to attach levers
movement
only happens in the joint tendons attach muscle to bone
mineral storage
transfrom spongy bone into rigid structure
blood cell production
bone marrows which white blood cells
platelets
red blood cells
functions of ligaments
stablize the joints
function of cartilage
cushions the joint
prevents friction
wear and tear beweteen the bone ends
Explain how the different parts of a synovial joint help it to move freely.
has oil to help it move freely
how do ligaments prevent injury
prevents the bones from twisting
flexion
decreasing the angle at a joint
extension
increasing the angle at a joint
abduction
moving away from the midline
adduction
moving towards the midline of the body
rotation and circumduction
circular movement
Plantar Flexion
the action of pointing toes away from the body
Dorsi Flexion
the action of pulling toes towards the body
agonist
the muscle in control of the action
antagonist
the muscle that needs to be relaxed to move a joint is known as the antagonist
concentric
the muscle shortens during the contraction
eccentric
the muscle lengthens
