System based anatomy versus regional?
gional is by region of the body
- standing position
- feet shoulder width apart
Anatomical Postion - head, gaze, toes forward
- joints in fully extended position
- palms forward
due to the position of radius and ulna - radius along entire
Why are the palms facing forward in anatomical positon?
length of ulna
what is unilateral? on one side only
What is bilateral? both sides
What is insalateral? on the same side of the body
What is contralateral? opposite side of body
1.) longitudinal axis
What are the three longitudinal planes of reference? 2.) sagittal axis
3.) transverse axis
What intersection forms the longitudinal axis? intersection of sagittal and frontal plane
What intersection forms the sagittal axis? intersection of sagittal and transverse plane
What intersection forms the transverse axis? intersection of transverse and frontal planes
How do limbs move? along one of the axises
1.) uniaxial
What three characteristics define synovial joints? 2.) biaxial
3.) multiaxial
What is uniaxial? movement in one plane
What is biaxial? movement in two planes
What is multiaxial? Move in multiple planes or axes
, What are the six types of synovial joints? hinge, condyloid, ball and socket, plan, pivot, saddle
What joints are biaxial? saddle and condyloid
What joints are uniaxial? hinge and pivot
What joints are multiaxial? ball and socket and plan
allow for wobble from side to side and rolling from front
What does a condyloid joint do?
to back (wrists)
rolling back and forth and side to side (shoulders and
What does a ball and socket joint do?
hips)
What does a plane joint do? permit glid (tarsal bones)
What do pivot joints do? allow for only rotation (C1 and C2 vertebra)
What do saddle joints do? surface glide down and front to back
How many vertebrae are there? 33
How many inferior vertebra fuse early in life? 9
How many superior vertebrae are individual? 24
Why do vertebrae become larger moving from cervical to
to support the weight
lumbar?
Why is the sacrum smaller at the bottom? because weight is distributed out towards limbs
What are the five regions of the vertebral column? cervical, thoracic, lumbar, sacral, coccygeal
How many cervical vertebrae are there? 7
How many thoracic vertebrae are there? 12
How many lumbar vertebrae are there? 5 (L1-L5)
How many sacral vertebrae are there? 5 fused
How many coccygeal vertebrae are there? 3-5
Where does the body of vertebrae lie? anterior
Where does the arch lie? posterior
