Chapter 1 7 Lecture HUMAN ANATOMY Chapter 7 The Skeletal System: Appendicular Division
Introduction The appendicular skeleton is involved in changing your position in the external environment. Standing Walking Sitting Dressing Driving a car
Introduction Figure 7.1 The Appendicular Skeleton The Pectoral Girdle and the Upper Limb Includes the S-shaped clavicle (collarbone) and the flattened scapula (shoulder blade). The clavicle articulates with the sternums
manubrium; is the only direct connection between the axial skeleton and the pectoral girdle. The scapula is attached to the clavicle anteriorly but has no connection to the actual axial skeleton; instead skeletal muscles and ligaments support it. The Clavicle

Figure 7.7d The Anterior Forearm The Wrist and Hand The carpal bones are the eight bones of the wrist. The five metacarpal bones articulate with the distal carpal bones and make up the palm of the hand.
The fourteen phalanges of the hand make up the finger bones. Hand SLTPTTCH The Pelvic Girdle and Lower Limb The pelvic girdle supports and protects the lower viscera and developing fetus in females.
The bones of the pelvic girdle and lower limb are much more massive than their homologues of the upper limb. Consists of two ossa coxae bones. The lower limb includes the thigh (femur), kneecap (patella), leg, (tibia and fibula), ankle (tarsals), and foot (metatarsals and phalanges).

Figure 7.11a Anterior Pelvis Figure 7.11b Posterior Pelvis The Pelvis: Male vs. Female The male and female pelvis contains numerous differences. Generally the male pelvis is heavier with more
prominent markings due to the larger muscles attached to it. The Pelvis Figure 7.12a Superior Pelvis Figure 7.12c Inferior Pelvis
The Pelvis: Male vs. Female Characteristics of the female pelvis:
Enlarged pelvic outlet, due to wider ischial spines Less curvature of the sacrum and coccyx Wider, more circular pelvic inlet Broader, lower pelvis Widely fanning ilia Pubic angle greater than 100 The Femur: Anterior Femur
