Proximal Humerus And Shoulder Girdle Chapter 6

Front 1

What is the largest and longest bone of the upper limb?

Back 1

Humerus; its length on an adult equals approx. one-fifth of the body height.

Front 2

The humerus articulates with the
________ at the shoulder joint.

Back 2

scapula(shoulder blade)

Front 3

The most proximal part of the humerus is the ____________.

Back 3

rounded head

Front 4

The slightly constricted area directly below and lateral to the head is the
__________.

Back 4

anatomic neck, which appears as a line of demarcation between the rounded head and the adjoining greater and lesser tubercles.

Front 5

The process directly below the anatomic neck on the anterior surface is the_____________.

Back 5

lesser tubercle

Front 6

The larger lateral process is the_______, to which the pectoralis major and supraspinatus muscles attach.

Back 6

greater tubercle

Front 7

The deep line between the two tubercles is the_________.

Back 7

intertubercle groove(bicipital groove)

Front 8

The tapered area below the head and tubercles is the____________.

Back 8

sugical neck

Front 9

Distal to the surgical neck is the long_________ of the humerus.

Back 9

body (shaft)

Front 10

The surgical neck gets its name because it is the site of___________

Back 10

frequent fractures requiring surgery

Front 11

The__________ is the roughened raised triangular elevation along the anterolateral surface of the body (shaft) to which the deltoid muscle is attached.

Back 11

deltoid tuberosity

Front 12

The shoulder girdle consists of two bones: the_______ and the ________.

Back 12

clavicle and the scapula

Front 13

What is the function of the clavicle and scapula?

Back 13

is to connect each upper limb to the trunk or axial skeleton.

Front 14

Anteriorly the shoulder girdle connects to the___________________.

Back 14

trunk at the upper sternum, but posteriorly the connection to the trunk is incomplete because the scapula is connected to the trunk by muscles only.

Front 15

Each shoulder girdle and upper limb connect at the shoulder joint between the___________________.

Back 15

scapula and the humerus.

Front 16

Each clavicle is located over the upper, ____________.Each scapula is situated over the upper,____________.

Back 16

anterior rib cage
posterior rib cage

Front 17

The upper margin of the scapula is at the level of the_____________, and the lower margin is a the level of the______________.

Back 17

second posterior rib,seventh posterior rib (T7) Note: the lower margin of the scapula coresponds to T7

Front 18

The clavicle(collar bone) is a long bone with a double curvature having three main parts:

Back 18

the two ends and the long central portion.
1)acrmioclavicular
2)sternoclavicular
3)jugular notch

Front 19

What consists of the joint or articulation that is termed acromioclavicular joint?

Back 19

The lateral or acromial extremity of the clavicle articulates with the acromion of the scapula.

Front 20

What consists of the joint or articulation that is termed sternoclavicular?

Back 20

The medial or sternal extremity
(end) articulates with the manubrium, which is the upper part of the sternum.This joint is easily palpated.

Front 21

The third and most important clavicle positioning landmark is the jugular notch and is formed by____________.

Back 21

the combination of the sternoclavicular joints on either side of the manubrium helps form the important landmark called the jugular notch.
