Upper limbs

Question 1

pectoral girdles

Answer 1

shoulder girdles (2) composition = clavicle (collar bone) + scapula (shoulder blade)

Question 2

Clavicle bone markings

Answer 2

1. Sternal (medial) End: joins the Clavicular Notch on the Manubrium of the Sternum 2. Acromial (lateral) End: articulates with the Acromion of the scapula. (Acromial: Shoulder - (axial) akron = peak; omos = shoulder.)

Question 3

Clavicle function

Answer 3

supports the scapula and arms Protects deeper structures (BV) in the upper chest Transmits impact from the arms to the axial skeleton

Question 4

Humerus articulations

Answer 4

1. Proximally with the Glenoid Fossa of scapula 2. Distally with the Olecranon Fossa of the Ulna (Olecranal = bony projection of the ulna behind the elbow joint posterior elbow region -(axial) Olene = ‘elbow’ and ‘kranion’ = head.)

Question 5

tuberosity

Answer 5

tuberosus = full of lumps. Resembles a bulb, protuberance. << than tubercle ex. Deltoid tuberosity (humerus)

Question 6

Tubercle

Answer 6

tuberculum = a little swelling, diminutive of tuber. ex. greater and lesser tubercle (humerus) >> than tuberosity

Question 7

Carpals (She looks too pretty try to catch her)

Answer 7

Scaphoid Lunate Triquetrum Pisiform Trapezium Trapezoid Capitate Hamate

Question 8

Scapula

Answer 8

Acromion + spine (attach clavicle) Glenoid cavity (for the humerus) Medial border (parallel to vertebra) Lateral border Coracoid process (anchors biceps muscles) Spine Supraspinous fossa Infraspinous fossa Subscapular notch
