Skeletal and Muscular Systems Review Flashcards
main function of skeletal system
support and protect body
5 additional functions of skeletal system
-support to help maintain the body’s shape
-protection from injury
-storage (bones store calcium, bone marrow stores iron)
-Aid in movement (bones give muscles something to attach to)
- Blood is made in the bones
what is the function of a Ligament?
connects bone to bone or cartilage to bone
the solid, rigid, outer bone
Compact Bone
inner bone with holes that contains red marrow
spongy bone
function of Yellow Marrow?
stores fat in long bones
Red Marrow
makes blood in spongy bone
cushion between bones and makes up your nose and ears
cartilage
what part does calcium play in bones?
most common mineral in bones
ball and socket
definiton
Allows movement in all directions
hinge definition
only moves forward and backwards
examples of ball and socket
shoulder and hip
examples of hinge
elbow and knee
sliding and gliding
definiton
small bones that move freely
examples of sliding and gliding
wrist and ankle
pivitol
defintion
allows for rotational movement
Top section vertebrate

how many vertebrate are in the Thoracic section
12 vertebrate + 24 ribs (12 on each side)
4th section vertebrate
Sacrum
how many vertebrate are in the Sacrum section
5 fused together
3rd section vertebrate
lumbar
how many vertebrate are in the Lumbar section
5
last section vertebrate
coccyx
how many vertebrate are in the coccyx section
4 fused together
can u label a bone?
YA
how many ribs do you have one each side
12
how many total ribs do you have
24
what section do the ribs connect to
Thoracic
what does the vertebral column protect
spinal cord
main function of Muscular System
movement
4 additional functions of muscular system
- posture
- helps with balance
-strength - generates heat through movement and friction
a muscle that bends a part of your body
flexor
a muscle that straightens a part of your body
extensor
what muscle do you always bend towards
flexor
when a muscle contracts, it gets
shorter and pulls on a bone
when a muscle relaxes, it gets
longer and allows the opposite muscle to pull on the bone
when one muscle contracts, the other must
relax
which muscle in the arm is the flexor
bicep
which muscle in the arm is the extensor
tricep
which muscle in the leg is the flexor
quadriceps
which muscle in the leg is the extensor
hamstrings
muscle found in the heart
cardiac muscle
muscle found in the digestive tract and blood vessels
smooth muscle
muscle found connected to bones to move the body
skeletal
voluntary muscles ex
sometimes skeletal
involuntary muscles ex
smooth, cardiac, and sometimes skeletal
Body system interactions?
Yes
Muscle diagram?
Yes
Bone diagram?
Yes
the muscular system helps the cardiovascular system by what
beating the heart so it can push blood around the body
the skeletal system helps the cardiovascular system by what
by making blood
the muscular system helps the digestive system by what
pushes food through the digestive tract
the muscular system helps the respitory system by what
moves diaphragm down and up (inhale exhale)
