Axial / App Skelton
Axial Skelton and Appendiclar Skeleton
Question | Answer |
---|---|
How many cervical vertebrae are there? | 7 and C1 = Atlas and C2 = Axis |
How many Thoracic Vertebrae are there? | 12 including T1 - T12, they are larger than the cervical vertebrae and articulate with the ribs |
How many Lumbar Vertebrae are there? | 5 including L1 - L5, they are the largest bertebral bodies and support the weight of the upper body |
The Sacrum is composed of? | five fused bones |
Where is the Sacrum located? | On the posterior side of the pelvis |
The Coccyx is also known as the? | tailbone |
Where is the Sternum located? | anterior area of the chest where rib cage comes together with the collar bone |
The ribcage is the home of the? | diaphragm (that works with the intercostals to assist respiration) and lungs |
What sits on the ribcage? | Scapulae |
The Clavicle and Femur are part of what skeleton | Appendiclar |
Functions of the Clavicle (collar bone) | connects the scapula to the sternum and forms two joints - setrnoclavicular and acromioclavicular - helps to hold the shoulder in place during arm movement |
Definition of the Subscapular fossa | the anterior surface of the scapula |
Definition of the Spine (appendiclar skeleton) | the prominent edge of the posterior surface of the scapula |
Definition of the Acromion Process | joins with clavicle to form acromioclavicular joint |
Definition of the Coracoid Process | site of muscle attachment for shoulder joint |
Definition of Glenoid Cavity | oval hole on lateral scapula forming the glenohumeral joint |
The Femur is? | the longest/heaviest bone in the body. |
How does the Femur form the hip joint? | smooth rounded head articulates with acetabulum of the coxal bone |
The Greater Trochanter is the? | upper lateral process of the femur |
The Lesser Trochanter is the? | lower medial process of the femur. the distal end has medial and lateral condyles that articulate with lower leg. |
The Patella - | fits into a groove between the two condyles of the femur. |
The Patellofemoral joint is where - | the patella meets with the femur |
The Tibiofemoral joint is where - | the femur meets with the tibia |
Misalignment of the patellofemoral and the tibiofemoral joints can cause | chondromalacia or a soft/split on the posterior surface of the patella |
The Tibia is the | larger of two lower leg bones on the medial side - the proximal end articulates with the femur |
The fibula is the | thin, twisted bone on the lateral side, articulates with tibia but not femur and makes rounded bump of ankle |
