Movement Flashcards
What are long bones
longer than wide, consists of spongy compact bone good at weight bearing
what are short bones
very light bones that are spongy not good for weight bearing
name 3 bone cell types
osteoclasts, osteoblasts osteocytes
what are osteoblasts
bone building
what are osteoclasts
breaking down old bone
what are osteocytes
provide nourishment to the bone
how does calcium relate to the topic of bones
bones store calcium
list 3 types of cartilage
hyaline, elastic, fibrocartilage
what is the role of cartilage
to sustain weight and shock during movement
what is a joint
where bone connects to bone
list 5 types of synovial joints
hinge, ball and socket, pivot, saddle, gliding
what are the 3 types of muscle
smooth skeletal cardiac
what is the skeletal muscle responsible for?
voluntary movement. can become weak
what is smooth muscle used for
involutary movement
what are the cardiac muscles used for
regular involutary movements that push blood into the vessels do not become weak
what must muscles do?
contract, return to normal shape, respond to neuron messages protect internal organs
where is smooth muscle found?
hollow organs stomach, gi tract blood vessel walls
function of flat bones
protect internal organs
2 examples of irregular bones
verterbrae pelvis
2 examples of seasamoid bones and their function
patella, hand bones. reinforce tendons
what are the 4 characteristics that make up synovial joint structure
Joint capsule: provides casing around ends of bones binding them to each other
Synovial Membrane: most slippery membrane that lines the inner surface of joint capsule - secrets fluid which lubricates surfaces
Ligaments holds bone together
articular cartilage cushioning
what is the name of the neurotransmitter responsible for muscle movement
ACH - Acetycholine
what is a
postsynaptic cell
presynaptic
- cell recieving message
2. cell sending message
what is a synapse
gap between the cells
Depolarisation
ICF is made more positively charged/Na movement across the cell membrane into he ICF
Repolarisation
ICF becomes less positively charged to attempt to return to normal - when K leaves cell
what are the proteins involved with muscle contractions
Tropomyosin, Troponin
For muscle stimulation where is calcium stored
Sacroplasmic reticulum SR - which is inside the ICF (releases calcium)
what are myosin and actin
proteins responsible for movement of skeletal muscle
what is NSAID
Non steroidal anti imflammatory
What is the difference between a generic and trade name
Generic name: name given to the drug by a manufacturer
Trade name: brand name, or name given by the company
what does the term form mean
different ways to prepare medication
Pharmacokinetics
Movement of a drug through the body (absorption)
Absorbtion
Medication travelling from the site of administration to the blood stream
DIstribution
ability of the medication to travel to the site where it is needed
metabolism
breaking down of medications to a lesser state
Therapeutic effect
desired effect
Adverse effects
Unexpected effects
side effects are
Unexplained, yet usually predictions and manageable effects
