The large concave depression, or notch, that articulates with the
distal humerus is the

trochlear notch

How well did you know this?

Perfectly

the expanded distal end of the humerus

humeral condyle

is shaped like a pulley or spool;

trochlea

humeral condyle is divided into two

trochlea and capitulum

smooth depressed center portion of troclea

trochlear sulcus

capitulum means

little head

2 epicondyle

lateral and medial

is the small projection on the lateral aspect of the distal humerus above the capitulum

lateral epicondyle

is larger and more prominent than the lateral epicondyle and is located on the medial edge of the distal humeru

medial epicondyle

both anterior and posterior surfaces. The two

radial and coronoid fossa

The deep posterior depression of the distal humerus is the

olecranon fossa

good criterion by which to evaluate a true lateral position of the elbow when it is flexed

90°

is the largest and longest bone of the upper lim

humerus

The first and smallest arc

trochlear sulcus

the length of humerus on and adult equals to

one-fifth of body height.

The humerus articulates with the

scapula

most proximal part of the humerus is the

head

the slightly constricted area below the head is called

anatomic neck

where did the most common fracture on the humerus happen

surgical neck

what do you call to the deep groove between the 2 tubercles

intertubercular groove

The roughened raised triangular elevation along the anterolateral surface of the body

deltoid tuberosity

ulnar deviation projection is commonly known as

special scaphoid project

that opens and best demonstrates the carpals on the opposite,

Radial deviation

The forearm routinely should be radiographed in what position

AP (hand supinated)

The shoulder girdle consists of two bones:

clavicle and the scapula

function of the clavicle and scapula

connect each upper limb to the trunk or axial skeleton.

what is the level of the upper and lower margin of the scapula respectively?

T2 and T7

flat triangular bone with three borders, three angles, and two surfaces.

scapula

three borders of scapula

medial, superior and lateral

medical term for armpit

axilla

the border nearest the axilla

lateral (axillary) border

the uppermost margin of the scapula

superior border

long edge or border near the vertebrae

medial (vertebral) border

The lateral angle, sometimes called the

head of the scapula

is the thickest part and ends laterally in a shallow depression

head of the scapula

the shallow depression of lateral angle is called

glenoid cavity

The humeral head articulates with the glenoid cavity of the scapula to form the

scapulohumeral joint

The constricted area between the head and the body of the scapula

neck.

thin, flat, lower part of the body of scapula sometimes is referred to as

wing of scapula

is a long, curved process that extends laterally over the head of the humerus

acromion

anterior surface of the scapula

costal surface

The middle area of the costal surface presents a large concavity or depression

subscapular fossa.

a thick, beaklike process that projects anteriorly beneath the clavicle.

coracoid process

a smooth triangular area and continues laterally to end at the

acromion.

Three joints or articulations are involved in the shoulder

sternoclavicular joint, acromioclavicular joint, and scapulohumeral joint

what are the 27 bones of the hand and wrist

1. Phalanges (fingers and thumb) 14 2. Metacarpals (palm) 5 3. Carpals (wrist) 8

The three shoulder girdle joints (articulations) classified as

synovial joints

movement type of scapulohumeral joint

spheroidal(ball and socket) flexion, extension, ab and adduction, medial and lateral, and circumduction

which constitute the digits (fingers and thumb).

phalanges

consists of the bones of the wrist

carpals

four fingers (digits 2, 3, 4, and 5) is composed of three phalanges—

phalanges—proximal, middle, and distal

Each phalanx consists of three parts

head, body, base

a boat-shaped bone, is the largest bone in the proximal row

scaphoid,

(moon-shaped) is the second carpal in the proximal

lunate

distinguished by its pyramidal shape and anterior articulation with the small pisiform

triquetrum

(pea-shaped), the smallest of the carpal bones,

pisiform

a four-sided, irregularly shaped bone that is located medial and distal to the scaphoid and proximal to the first metacarpal

trapezium

the smallest bone in the distal row

trapezoid

the largest of the carpal bones
