1. Anatomy Term & Gait Cycle Flashcards
Where is the midline of the foot ?
The second toe
What bones makes up the axial skeleton?
Skull Vertebral column Ribs Sternum Sacrum Coccyx
What bones makes up the appendicular skeleton?
Bones of the extremities
Whats another word for hip?
Coxal
Another word for leg?
Crus
Another word for Calf?
Sural
Word for the ankle?
Talus
What’s Open chain?
The foot is off the ground and not weight bearing
What is closed chain?
The foot is on the ground and weight bearing
At the hip joint, flexion and extension takes place in what plane and axis?
Mediolateral / transverse axis
Within the sagittal plane
During flexion/extension and abduction/adduction of the hip joints, What happens to the pelvis and femur during open and closed chain movements?
Open chain: pelvis is fixed and femur moves
Closed chain: the the pelvis moves and the femur is fixed
Abduction and adduction of the hip joints takes place in what plane and axis?
About the anterolateral axis
Within frontal/coronal plane
What plane and axis does internal and external movement of the hip joint happen?
Longitudinal axis
Horizontal plane
What movement happens at the hip?
Extension/Flexion
Abduction/Adduction
Lateral/Medial
What movements occurs at the knee?
Flexion/Extension
On what plane and axis that knee extension/flexion occur?
Mediolateral/transverse axis
Within sagittal plane
In what plane and axis does dorsiflexion/plantar flexion occur
Oblique mediolateral/transverse axis
Oblique sagittal plane
The line of gravity lies
Hip: posterior to hip
Knee: anterior to knee
Ankle: about 2 inches anterior to ankle
The line of gravity will tend to do what at the COG of the lower limb and what limits these actions?
Hip: hyperextend
Limited by: illiofemoral ligament(Y ligament) & ischiofemoral ligament
Knee: hyperextend
Limited by: intracapsular and extracapsular ligaments & gastrocnemius
Ankle: dorsiflex
Limited by: gastrocnemius & soleus (plantar flexors)
