soft tissue approximation

Question 4

flex the shoulder from an extended position. is the humerus moving on the scapula, or is the scapula moving on the humerus?

Answer 4

humerus is moving on scapula

Question 5

flex the shoulder from an extended position. is the proximal end of the humerus a concave or convex joint surface?

Answer 5

proximal end of humerus is convex

Question 6

flex the shoulder from an extended position. does the glenoid fossa of the scapula have a concave or convex joint surface?

Answer 6

glenoid fossa of scapula is concave

Question 7

Answer 7

convex surface is moving on a fixed concave

surface

Question 8

flex the shoulder from an extended position. is the joint surface moving in the same or opposite direction as the joint motion?

Answer 8

opposite direction

Question 9

leaning on a table with your elbows extended

Answer 9

compression or approximation

Question 13

swinging a child around by their arms

Answer 13

Question 14

is the temporomandibular joint (TMJ) (jaw) in the
close-packed position when the teeth are clenched
or when the mouth is slightly open?

Answer 14

close-packed position of TMJ is when teeth are clenched

Question 15

rotating a quarter on its edge across the table
demonstrates what type of arthrokinematics
motion?

Answer 15

roll

Question 16

lay the quarter flat on the table and hit it with
your finger, sending it across the table. this would
be what type of arthrokinematics motion?

Answer 16

glide (slide)

Question 17

hold a pencil vertically with the lead end on the
table. Holding the eraser end between your thumb
and index finger, roll the pencil between your fingers, keeping the lead end in contact with the table. this is demonstrating which type of arthrokinematic motion?

Answer 17

spin

Question 18

assuming muscles are of normal length and taking
a person’s ankle into dorsiflexion, you would
expect what type of end feel?

Answer 18

soft tissue stretch

Question 19

a person bends down to touch the floor in the
sagittal plane. what type of force is applied to the anterior part
of the vertebra?

Answer 19

compression

Question 20

a person bends down to touch the floor in the
sagittal plane. what type of force is applied to the posterior
part of the vertebra?

Answer 20

distraction

Question 21

sitting in a chair, a man turns around to look
behind him. what type of force is being applied to
the vertebral column?

Answer 21

torsional

Question 22

the surfaces of the thumb metacarpophalangeal

(MCP) joint are what shape?

Answer 22

ovoid

Question 23

is the rotational motion at the thumb carpometacarpal (CMC) joint considered a classical movement or an accessory movement? why?

Answer 23

accessory; rotation cannot be done alone. it occurs

when that joint abducts and flexes, thereby accomplishing opposition
