skeletal,muscular, integumentary system Flashcards
strong body tissue that can contract in an orderly way
muscle
body system that contains bones and other structures that connect, contract, and protect the bones and support other functions in the body
skeletal system
what are the main functions of the muscular system
movement, maintaining body temperature, posture, protecting internal organs
what are the types of muscle tissue
skeletal, smooth, cardiac
the type of muscle that move bones
skeletal muscles
the type of muscle that regulates blood pressure, digestion , and internal functions
smooth muscles
muscles found only in the heart
cardiac muscle
what is an example of a skeletal muscle
bicep
what is an example of a smooth muscle
stomach, bladder, blood vessels
how does the muscular system help with homeostasis
The bones supply calcium to your nerves, muscles and heart.
why must your muscles work in pairs
because they can only pull
a place where two or more bones meet
joint
what are the types of joints
fixed, ball and socket, pivot, hinge, gliding joint
joint with no movement
fixed joint
allows one bone to slide over another
gliding joint
rotating bone turns around an axis
pivot joint
joint between bones that allows motion only one plane
hinge
almost 360 degrees range movement
ball and socket
where can fixed bones be found
skull and hip bones
where can gliding joint be found
wrists and ankles
where can pivot joint be found
connection between radius, ulna, humerus,
where can hinge joint be found
elbow and knee
where can ball and socket joint be found
shoulder and hip joint
a bone disease that causes bones to weaken and become brittle
osteoporosis
a disease in which joints become irritated or inflamed
arthritis
how does the skeletal system help with homeostasis
supply calcium
muscle that you can consciously control
voluntary muscle
muscle that you can’t consciously control
involuntary muscle
a strong flexible tissue that covers the ends of the bone
cartilage
the tissue that connects bones to other bones
ligaments
why do you need both muscles and tendons to move your body
muscles are able to pull on the bone for movement and tendons connect your bones
stores fat
yellow bone marrow
red blood cells
red bone marrow
what are the two parts of the skeletal system
axile and eppindicular
center of the skeleton
axile
all the limbs outside the axial skeleton
eppendicular
list the four layers of bone
periosteum, compact, cancellous bone, marrow,
thin membrane that covers and protects; contains blood vessels and nerves
periosteum
n/a
n/a
porous bone; contains blood vessels and marrow
cancellous bone
hard bone that provides structure to the bone
compact bone
jelly-like center of bones
marrow
destroy bones
osteoclasts
build bone
osteoblasts
hold bone together
osteocytes
protection of bone
lining cells
What are the main minerals in your bones?
Calcium and phosphorus
Explain how your bones change as you get older
your skeleton begins as cartilage, which is gradually broken down and replaced by a bone
how many bones do babies have
300
how many bones do adults have
206
