Description

SET 8 the apendicular skeleton Pectoral girdle • attaches the upper limbs to the trunk Pelvic girdle • attaches the lower limbs to the trunk Upper and lower limbs • differ in function • similar structural plan

the pectoral girdle • Clavicle and Scapula • Pectoral girdles do not encircle body completely • Clavicle • Medial end-articulates with the manubrium and first rib • Lateral end-join the scapulae • Scapulae do not join each other or the axial skeleton • Attachment for muscles • upper limb movement • Very light and mobile • Only clavicle articulates with the axial skeleton • Glenoid cavity is shallow • Good flexibility • Poor stability

clavicles • Attachment for muscles • Pectoralis major

• Trapezius • Sternocleidomastoid • Deltoid • Hold the scapulae and arms laterally • Transmit compression forces • from upper limbs • to axial skeleton

scapulae • On dorsal surface of rib cage • Between ribs 2-7 • 3 borders • Superior • Medial (vertebral) • Lateral (axillary) • 3 angles • Lateral • Superior • Inferior

acromian

the upper limb • 30 bones form each upper limb • Grouped into bones of the: • Arm • Forearm • Hand
