Anatomy Chapter 7 The Skeletal Assessment
How many vertebrae are in each section of the vertebral column?
7, 12, 5
What makes up the "true wrist?"
8 short bones (Carpals)
What is the major function of the intervertebral discs?
Absorb shock
Which vertebra does not have a body?
Atlas
How do the first two cervical vertebrae differ from other cervical vertebrae? What are their functions?
Atlas- Has no body, articulates with the skull unless you do a "yes" motion Axis- Projection called the dens, allows your head to do a "no" motion
Which bone lets the head say no?
Axis
Where is the dens and what does it articulate with?
Axis- Helps articulate with the atlas
The heel bone is called what?
Cacaneus
Which vertebrae contains the joint that allows you to rotate your head "no?"
Cervical
Which vertebrae have transverse foramina present?
Cervical
Which vertebrae include the atlas and axis?
Cervical
Which bone(s) have no canals or foramen present?
Coccyx
Layman's term for clavicle?
Collar bone
What material joins the ribs to the sternum?
Costal cartilage
Most common place for humerus to fracture
Distal end
What do the anterior and posterior longitudinal ligaments of the vertebral column do?
Holds everything in place
Which bone articulates with the glenoid fossa?
Humorus
What is the largest portion of the coxal bone?
Ilium
Describe the composition of the intervertebral disc
Inter vertibral disc are composed of inner semi fluid nucleus pulposus This gives discs elasticity and compressibility Cover of fibro cartilage called anulus, limits expansion of vertebrae
What are the three parts of the pelvic girdle?
Ischium, ilium, pubis
What parts of the femur articulate with which parts of the tibia?
Lateral condoyles
Describe the different between the bones of the lower and upper limb and briefly state why these differences exist
Lower limbs carry the weight of our body. They are thicker and stronger Upper limbs are smaller and lighter. They are adaptive for flexibility and mobility
Which bones receive the most stress?
Lumbar
Which part of the vertebral column receives the most stress by bearing most of the weight of the body?
Lumbar region
The largest foramen of the body is?
Obturator
What is the funciton of the vertebral curves?
Provide resilience and flexibility
What is the major function of the axial skeleton?
Provides support for the body and protects internal organs
Know which bone articulates with the carpals.
Radius
What does the term vertebronchondral mean?
Ribs attach to each other before they attach to the sternum
Which bones of the vertebral column articulates with hip bones of the pelvis?
Sacrum
What composes the axial skeleton?
Skull, vertebral column, rib cage
Which bones of the vertebral column attach to ribs?
Thoracic
Which of the following bones is not weight bearing?
Tibia takes all the weight. Fibia isn't weight bearing
Know the different ribs numbers and what are they called?
True (1-7) False (8-12) Floating (11 & 12)
What marking on the rib articulates with the transverse process of a vertebra?
Tubercle
