3rd test on bones Flashcards
skull
cranium
clavicle
collarbones

Ulna
lower part of arm, one of 2 bones, elbow to wrist (inside of the two)
Phalanges
small bones in fingers and toes (numbered)
Femur
“thigh”, top of leg (longest bone in the body)
what does the femur determine?
it genetically determines height
Tibia
lower part of leg, one of the 2 bones, knee to ankle (Bigger of the two bones)
Fibula
lower part of leg, one of the 3 bones, knee to ankle (smaller of the bones)
Carpal bones
wrist bones
Metacarpals
hand bones
Tarsal bones
ankle bones
Metatarsals
foot bones
Coxal
hip bones
Vertebrae
spinal bones
Mandible
jaw
Patella
knee cap
Sternum
chest bone (vertical)
Ribs
chest ones (cage)
how many bones in the human body
206
What are the 4 functions of the skeletal systems
- support/structure 2. storage of calcium and minerals 3. blood cell production 4. protection
How does the skeletal system function of support/structure work?
its the internal framework that makes us look “human”
How does the skeletal system function of blood cell production work?
blood is made in the MARROW of the bones
How does the skeletal system function of protection work?
protect major organs from injury
what are the 4 types of bones?
Long, Short, Flat, and Irregular
How many muscles in the body?
656
What is a long type of bone?
Femur (thigh), Humorous (upper arm)
What is a short type of bone?
Phalanges (fingers
What is a flat type of bone?
cranium (skull), ribs (12), clavicle (shoulders)
What is an irregular type of bone?
vertebrae (26 fused bones)
What is the skeletal system divided into?
axial skeleton and appendicular skeleton
How many bones are in the axial skeleton
80 total bones
What are the 3 main areas of the axial skeleton
Cranium, Vertebrae (spinal column) and Thorax (chest cavity)
how many bones are in the cranium
22 (8 from the cranium and 14 from the face)
what process does the skull undergo
ossification
what is ossification
soft, disconnected bones FUSE to form a “plate” or one main bone
what is an example of ossification
infant skull
how many bones are there in the vertebra
26; numbered form the base of neck to lower back
what does the vertebrae form
a COLUMN or enclosure fro spinal cord
what is the thorax
ribs and sternum (vertical chest bone)
what is the thorax made up of
12 pairs of ribs
how are the twelve pairs of ribs divided
first seven pairs and the last five
what are the first seven pairs of ribs called
true ribs
where are the true ribs
attached to the sternum
what are the last five pairs of ribs called
false ribs
where are the false ribs
not attached to sternum, floating
what do the end of ribs contain and for what purpose
cartilage; for slight flexibility to prevent breaking
how many bones make up the appendicular
126
what makes up the appendicular skeleton
upper an lower limbs and pelvic girdle
how do the wrist and ankle bones compare
wrist contains one extra bone for greater motion that the ankle
how do the thumb and big toe compare
thumb is opposable, able to move across the hand, while the big toe is unopposeable, not able to move across the foot
is the appendicular skeleton really needed
not needed for survival because it is replaceable with prosthetic devices
joints
where 2 bones meet
what are joints joined by
a tendon
what is a joints major function
movement
arthrology
study of joints
how many types of joints are there
6
what are the types of joints
immovable joints/ slightly moveable/ hinge/ pivot/ gliding/ ball and socket
range of motion for immoveable joints
0
example of a immovable joint
skull
range of motion for slightly moveable
less than 10
example of slightly moveable
ribs
range of motion for hinge
90 (one way)
example of hinge
elbow, knee
range of motion for pivot
180 (left to right)
example of pivot
neck
range of motion for gliding
multi direction; one bone slides over another
example of gliding
fingers
range of motion for ball and socket
360 (full circle)
example of ball and socket
shoulder
what is oseoporosis
reduction of calcium, bones become brittle, break easy
what is arthritis
inflammation of joints, pain, prevents motion
what is tendonitis
wear down, less movement, stiff pain
what happens to the skeletal system as it ages
oseoporisis, arthritis, tendonitis, flexibility decreases, normal wear and tear from usage and breaks, stiffness
cast
immobile (permanent or temporary)
pin
replaces bone material in a long bone
plate
replaces bone material in a flat bone
prosthetic device
artificial limb or joint replacement
physical therapy
goal is to restore function
bone density testing and replacement
one way of repair
what are the different types of bone fractures
simple,open, multifragmentary
simple fracture
a fracture of the bone only, without damage to the surrounding tissues or breaking of the skin
how to fix a simple fracture
just let the bone heal
open fracture
bones goes through the skin
how to fix an open fracture
surgery
multi-fragmentary
bone goes into many pieces
how to fix a multi-fragmentary fracture
pin, replacement, plate
arthritis
inflammation of a joint; results from bacterial or viral infections, metabolic problems or severe physical stresses
treatment for arthritis
medication, physical therapy, sometimes surgery to reduce the symptoms
osteomylitis
degenerative joint disease; can result from cumulative wear and tear at the joint surfaces or from genetic factors affection collagen formation
