Q

true vs false vs floating ribs

A

articulate directly to sternum by costal cartilage (1-7) vs articulate indirectly to sternum by joining costal cartilage to rib above it (1-8) vs no articulation to sternum (11-12)

21
Q

6 bones of calvarium

A

frontal, occipital, 2 parietal, 2 temporal

22
Q

4 parts of temporal bone

A

squamous, mastoid, tympanic, petrous

23
Q

14 facial bones

A

many monkeys live in very nasty public zoos: mandible, maxilla, lacrimal, inferior nasal concha, vomer, nasal, palatine, zygomatic

24
Q

6 cranial bones

A

step of 6: sphenoid, temporal, ethmoid, parietal, occipital, frontal

25
Q

UE characteristics

A

connected to axial skel by pectoral girdle; mobility and dexterity, grasp and strike, fine motor skills

26
Q

4 main segments of UE: shoulder/pectoral girdle vs arm vs forearm vs hand

A

includes clavicle, scapula, manubrium; proximal segment overlaps thorax vs b/w shoulder and elbow, anterior and posterior regions centered at humerus, proximal segment of free upper limb vs b/w elbow and wrist, anterior and posterior regions overly radius and ulna vs made of wrist/carpals, palmar and dorsal hand, digits; dexterity and lots of sensory nerves

27
Q

pectoral girdle

A

connects axial skel to UE; bone ring, incomplete posteriorly & completed anteriorly by articulating w/ manubrium, formed by scapulae and clavicles

28
Q

does forearm directly articulate w/ carpals?

A

no

29
Q

fibrous joints and 3 types

A

connected by fibrous tissue, no joint space, movement depends on fiber length that’s uniting the bones. syndemosis - bones united by sheet of connective tissue, gomphosis - movement indicating pathological state, suture

30
Q

cartilaginous joints and 2 types

A

connected by hyaline cartilage or fibrocartilage. primary synchodroses - united by hyaline cartilage, usually temporary and assoc w/ long bones; secondary symphyses - united by fibrocartilage (stronger than hyaline), strong and sl moveable

31
Q

ex of primary cartilaginous joint

A

as long bones grow, epiphysial plate made of hyaline cartilage separates diaphysis from epiphysis; costosternal joint = only permanent primary cart joint

32
Q

ex of secondary cartilaginous joint

A

intervertebral discs, pubic symphysis

33
Q

synovial joint

A

moveable joints like gleno-humoral/shoulder, hip, ankle; articular cartilage, synovial cavity, synovial membrane, joint capsule, ligament (intrinsic or extrinsic), synovial fluid

34
Q

degenerative joint dz

A

w/ age, articular cartilage becomes less effective shock absorber and less lubricated –> articular surfaces and underlying bone may erode –> pain assoc w/ movement; osteoarthritis affects joints that support body wt in older individuals, accompanied by stiffness/discomfort/pain

35
Q

6 types of synovial joints

A

plane - gliding/sliding in plane of articular surface (acromioclavicular joint), hinge - flexion/extension in 1 plane (elbow - humeroradial/ulnar joint), saddle - movement in 2 planes => biaxial like ab/adduction and flex/extension (carpo-metacarpal joint), condyloid - more movement in 1 of 2 planes, biaxial (metacarpophalangeal joints), ball and socket - multaxial like flex/extension, ab/adduct, M/L rotation, circumduction (hip, shoulder), pivot - rotation around central axis (median atlantoaxial joint C1/C2)

36
Q

intra-articular structures

A

stability and fxn, located w/in articular cavity; menisci = crescent shaped (not a complete disc), in knee joint; articular disk = disk shaped, in jaw/sternoclavicular joint/acromioclavicular joint/proximal wrist; articular labra = outer margins of hip and shoulder joint

37
Q

intrinsic vs extrinsic vs intracapsular ligaments

A

incorporated in wall of articular capsule (oblique popliteal ligament) vs outside of articular capsule, strengthens joint capsule (fibular like LCL and tibial collateral ligament MCL) vs inside of articular capsule (anterior/posterior cruciate ligament)

38
Q

Hilton’s Law

A

nerves supplying muscle extending directly across and acting on a given joint also innervate the joint; articular nerves transmit sensory impulses from joint that contribute to sense of proprioception

39
Q

fontanelles

A

in newborn calvaria/skull cap, bones don’t make contact –> connected by fibrous tissue => fontanelle; bulging fontanelle –> inc intracranial pressure, depressed fontanelle –> dehydration

40
Q

acetabular labrum

A

attached to acetabular rim and deepens socket, made of fibrocartilage –> more durable than hyaline

41
Q

3 ligaments of hip joint

A

iliofemoral (strongest), pubofemoral, ischiofemoral

42
Q

how do sprains happen?

A

fibers in ligaments = torn

43
Q

bipeds vs quadrupeds

A

angular arrangement to maintain center of mass, realigns lower limb to center of trunk –> allow full wt to shift for limb to limb vs body mass = centered b/w vertical limbs –> requires simult support on each side

44
Q

6 segments of LE: gluteal region vs thigh vs knee vs leg vs ankle vs foot

A

transition b/w trunk and free lower limb; butt and lateral hip; bounded by iliac crest and gluteal fold, overlies pelvic girdle vs b/w hip and knee; bound by inguinal ligament, ischiopubic ramus, gluteal fold vs popliteal in back/genual in front; includes condyles of distal femur, proximal tibia, patella, popliteal fossa vs b/w knee and foot, includes tibia and fibula vs talocrural region vs yep

45
Q

sacroiliac joints

A

for stability than mobility; assoc w/ anterior/posterior sacroiliac ligaments

46
Q

common tibia/fibula fx

A

cmpd fx aka bumper fx, stress fx, diagonal fx from excessive torsion, boot top fx

47
Q

forefoot vs midfoot vs hindfoot

A

phalanges vs meta/tarsals vs talus and calcaneus

48
Q

coxa vara vs coxa valga

A

<126 vs >126. wt = not distributed properly across knee joint –> instability
