A&P Lecture Exam 3

What is the function of the pectoral girdle, and which bones make it up?

Made up of clavicles and scapulae
Connects upper limbs to trunk
Allows for a wide range of shoulder movements

Bones of the upper limb

Humerus, radius, ulna, carpals (8), metacarpals (5), phalanges (14)

What is the function of the pelvic girdle, and which bones make it up?

Composed of sacrum and two os coxae (hip bones), which are formed by a fusion of ilium, ischium, and pubis
Supports weight of the upper body
Connects the lower limbs to the axial skeleton

Differences between male and female pelvises

Female: wider, shallower, subpubic angle is broader (>90°)
Male: narrow, deep, heart-shaped, subpubic angle is narrower (<90°)

What bones make up the lower limb

Femur, patella, tibia, fibula, tarsals (7), metatarsals (5), phalanges (14)

Arches of the foot (how many are there and what are their functions?)

-Medial longitudinal arch
-Lateral longitudinal arch
-Transverse arch
-Help distribute weight and absorb shock
-Maintain foot stability and flexibility
