True or false: A typical spine is completely straight when standing vertically.
False (note the typical curvatures in a spinal column)
True or false: The vertebral body is located anteriorly and can be palpated along the surface of the back.
False (located anteriorly, but the spinous processes are the structures that can be palpated along the surface of the back)
The vertebrae fit together to protect the __________, located in the vertebral canal.
The spinal cord
True or False: A typical thoracic vertebra has a bifid spinous process.
False
What is the purpose of transverse foramina in cervical spinal vertebrae?
Passage of vertebral arteries and veins
What region of the spine contains costal facets?
Thoracic
What is the purpose of costal facets?
Articulations with ribs
The line along the midline of the sacrum is called the
Median sacral crest.
Which region of the spine has the largest vertebral bodies?
Lumbar
True or False: Ribs 11 and 12 have no posterior attachment to the thoracic vertebrae.
False
Why is the glenohumeral joint prone to dislocation?
The glenoid cavity is very shallow and much smaller than the head of the humerus. The humerus needs to be held to the shallow glenoid cavity by the rotator cuff muscles and other ligaments
True or false: Anteriorly, the clavicle connects to the scapula.
False
True or false: The medial border of the scapula connects directly to the neck of the scapula.
False
True or false: The subscapular fossa is located on the anterior side of the scapula.
True
Review scapular bone landmarks.
See figures in module
The capitulum articulates with a small portion of the ______________.
Radius
True or false: The lateral epicondyle of the humerus can be palpated on the medial side of the arm at the elbow.
False
What is the prominent bone that can be palpated in the elbow posteriorly?
Ulna
Review humerus bone landmarks.
See figures in module of the humerus.
What structures connects the ulna and radius along their shafts?
Interosseous membrane
Review ulna and radius bone landmarks.
See figures in module
Name the four bones of the distal row of carpal bones.
The distal row of carpal bones (from lateral to medial) are: trapezium, trapezoid, capitate, and hamate.
Review all bones of the hand.
See figures in module of the hand.
What bone is highlighted in the figure? (Left hand)
Capitate
Do the carpal bones of the hand articulate with the metacarpals or proximal phalanges?
The metacarpals
The coxal bones are connected posteriorly to the ________________.
The sacrum
The superior most region on the ilium is called the _______________.
Iliac crest
The ASIS is a bone landmark on what bone?
Ilium
What bone landmark is highlighted in orange (center) in the figure below?
Iliac fossa
Review all bone landmarks of the coxal bones.
See figures in module
What are the main differences in the male and female pelvic shapes? Why?
The pubic arch is wider in females than in males. The pubic brim, also known as the pelvic outlet is shaped more like a circle in males and an oval in females. These differences are to accommodate childbearing
True or false: The intertrochanteric crest articulates with the acetabulum.
False
What bone landmark is highlighted in blue, along the center portion of the shaft?
Linea aspera
Review all bone landmarks of the femur.
See figure of the femur in module.
What bone lies anteriorly to the femur?
Patella
The medial malleolus of the ankle is a part of what bone?
Tibia
Review bone landmarks of the tibia and fibula.
See figures in module.
What bone of the foot is highlighted in blue below (left)?
Navicular
Review bones of the foot.
See figure in module
Name and describe the function of the contents of the medullary cavity of bone.
Yellow bone marrow is a fat storage tissue found mainly in long bones. Red bone marrow is found primarily in short and flat bones, primarily to produce red blood cells.
The center length of a long bone is called the _______________.
Diaphysis
This special type of cartilage is found at joint articulations.
articular cartilage
Which type of bone is lighter: Spongy or compact?
Spongy bone
Which type of bone is usually found on the external surface of bone: Spongy or compact?
Compact
Which type of bone cell is responsible for removing worn bone cells?

False
True or false: Endochondral ossification is the ossification of long bones from hyaline cartilage.
True
True or false: Intramembranous ossification is the formation of flat bones from connective tissue.
True
This type of fracture occurs when one end of the bone is pushed inside the other.
Impacted
This type of arthritis causes the synovial membrane to become inflamed.
Rheumatoid arthritis
What type of joint is immovable: Fibrous, cartilaginous or synovial?
Fibrous joints
Synovial joints produce what type of fluid?
Synovial fluid
The thumb has this type of synovial joint to allow the thumb to cross over the palm.
