ligaments
What holds the muscle to the bone
tendons
What are the bone categories ?
long bones
short bones
flat bones
irregular bones
What is the material found in between the bones ?
It helps the bones to move smoothly over each other.
cartilage
Which joint does the shoulder and hip fall into ?
This joint has the widest range of motion
ball and socket
This joint allows bones to move up and down. ( knees or phalanges)
hinge joints
This joint allows bones to slide along another. (wrist and ankles)
gliding joints
This joint is only in the thumbs
allows motion up and down and left to right.
saddle joints
This joint is found between the metacarpals and phalanges.
allows motion in 2 plans, up and down and left to right
ellipsoid joint
This joint allows rotating.
Allows the head to swivel right left.
pivot joint
The study of the structure, functions, disorder and diseases of the muscular system
myology
Group of muscles that are under conscious control.
We are thinking about moving these muscles.
voluntary muscles
These muscles move on their own…
cardiac muscles / smooth muscles
these muscles are found in internal organs and blood vessels.
smooth muscles
These muscles are found only in the heart
cardiac muscles
What are muscle fibers?
They are muscle
What forms the lower back and supports the weight of the entire upper body ?
lumbar
The name of the upper arm bone
the humerus
the lower arm bones
radius and ulna
name for the wrist bones
carpals
what is the largest gone in the leg, which is also the longest gone in the body ?
femur (thigh bone)
Name for the shin ?
tibia
Name for the ankle ?
tarsals
What do your lower appendages attach to ?
pelvic girdle
Name for the shoulder blades
scapulae
Name for the clavicle
collarbone
What is the trapezius muscle ?
Muscles that allow us to tilt our head so we can look up
allows us to shrug or pull our shoulders
Muscles that keeps our jaw closed ?
masseter and temporalis
What is the deltoid muscle ?
Allows our arms to go to the side and gives our shoulders curves
What are the 2 muscles that help with chewing?
temporalis / masseter
What is the largest chest muscle?
pectoralis major
pectorals/ pecs
What are the muscles that flex and extend your forearm ?
biceps brachii
triceps brachii
What muscles flex and extend the lower leg at the knee ?
quadriceps femoris & hamstrings
What movement describe most of the joints we have in our body ?
freely movable
What is the largest and strongest muscle in the body ?
( pulls the upper legs downward and backward)
gluteus maximus
This muscle decreases the angle between the bones of a joing
flexors
This muscle increases the angle between the bones
extensors
This bone is a rigid ring of thick bone that supports most of the body’s weight
( your lower appendages are attached )
pelvic girdle
This is the ability of a muscle to extend easily through its full range of motion
flexability
This is how much force a muscle or group of muscles can exert
muscular strength
