What are the three parts of the phalanges?

radius & ulna

What are the two bones of the Antebrachium (lower arm)?

lateral

When in the anatomical position, is the radius more medial or lateral?

radius; ulna; pronation & supination

When talking about the radius and ulna- the ____ pivots around the ______ to allow for ______.

radiocarpal/ulnocarpal

Which articulation of the wrist/hand is a condyloid, 2 axis, and flexion/extension and adduct/abduct?

metacarpophalangeal joints

Which joint of the wrist/hand is a condyloid, 2 axis, moves all around, and is where the head of the metacarpals meet the base of phalange?

5 (lateral/thumb to medial)

how many metacarpals are there?

14

how many phalanges are there?

interosseous border (margin)

landmark on the medial side of the radius, it is sharp, and the interosseous membrane attaches to it.

dorsal tubercle

landmark on the posterior radius, this is where the muscles of the thumb attach

tuberosity

landmark on the radius that is large & raised, the other end of the biceps brachii tendon attaches to this.

tuberosity

landmark on the ulna where the brachialis attaches, located below the hinge

interosseous border (margin)

landmark on the ulna where the interosseous membrane attaches, it is sharp

trochlear notch

landmark on the ulna which articulates with the trochlea of humerus, inside notch on proximal bone, "wrench"

neck

landmark that is directly below the head of the radius, separates the head and the radial tuberosity

head

landmark that is proximal, disc like shape on the radius

styloid process

landmark/point on the distal, lateral radius

radial notch

lateral notch on the ulna, this is where the radius 1st articulates with the head of the ulna

annular ligament

ligament which holds the radius to the ulna, it runs from the tubercle of the ulna and around the head of the radius

scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate (Scared Lovers Try Positions That They Can't Handle)

list the 8 carpals of the hand (lateral/thumb to medial)

head

located distal on the ulna, whole rounded projection

coronoid process

lower lip of the ulna's trochlear notch

styloid process

medial, distal, point on the ulna, projects off the head

olecranon process

proximal landmark on the ulna, this is where the hinge joint occurs in the olecranon fossa

proximal; distal

the head of the radius is _______, the head of the ulna is _______. (distal or proximal on bone)

saddle (thumb) and gliding (where the carpals and metacarpals meet)

what are the 2 types of joints of the carpometacarpals?

base, shaft, head

what are the 3 parts of the metacarpals and phalanges?

proximal, middle, distal (tip)

what are the three bones of the phalanges?

joint/membrane between the radius and ulna, syndesmosis (slightly movable, fibrous)

what is and where is the interosseous membrane?

radial collateral ligament or lateral collateral ligament

what is the ligament on the lateral side of the elbow?

ulnar collateral ligament or medial collateral ligament

what is the ligament on the medial side of the elbow?

condyloid (radiocarpal/ulnocarpal) & gliding (intercarpal) ?

what two types of joints make up the wrist?

hinge

what type of joint is the Interphalangeal joint?

pivot joint

what type of joint is the proximal ulnoradial joint?

hinge joint

what type of joint is the ulnohumeral joint?

ulna

when looking closer to the elbow, is the radius or ulna larger?

runs from the lateral epicondyle to the head of the radius

where does the radial collateral ligament run?

runs from the medial epicondyle to the ulna

where does the ulnar collateral ligament run?

trapezium

which carpal bone is that 1st on the distal row and also touches the thumb?

intercarpal joints

which joint of the wrist/hand is a gliding joint?

thumb (proximal and distal)

which phalange only has 2 bones?

distal interphalangeal joint
