Movement Flashcards
(25 cards)
list the types of bones
long bone, short bones, flat bones, irregular bones
diaphysis
central part of the bone
metaphysis
most narrow part of the bone
epiphyses
end part of the bone
periosteum
Dense white fibrous membrane , around the end of the bones
articular cartilage
smooth white tissue covering the end of the bone.
medullary cavity
marrow cavity, the central cavity of the bone
osteoblast
makes new bone
osteoclast
breaks down brittle or damaged bone
osteocytes
nourishment and protection for the bone
Fibrous joints
They don’t move. connected by fibrous tissue
cartilaginous joints
little movement, connected by cartilage
synovial joins
lots of movement
particular cartilage
surround the end of each bone in the joint inside the synovial fluid
neurotransmitter for muscles
ACH
is k+ inside or outside the cell
inside
is NA+ inside or outside the cell
outside
during polarity what happens to the NA+ cells
they go into he icf making the concentration in the cell more positive
when k+ leaves the cell what is this called
hypopolarisation
how does calcium relate to bones
bone store calcium
myosin and actin
proteins responsible for the movement of skeletal muscle
2 types of cartilage and responsible or
elastic - shock resistant during movement
5 synovial joints are
- ball and socket
- pivet
- saddle
- gliding
- hinge
the proteins responsible for muscle contraction
tropomyosin troponin
