Wrist Wrist made of 8 carpal bones Some
Wrist • Wrist made of 8 carpal bones – “Some lovers try positions that they can’t handle. ” – Scaphoid Lunate Triquetrum Pisiform Trapezium Trapezoid Capitate Hamate
Hand • 5 metacarpals – Numbered 1 -5, starting at thumb – Bones between wrist (carpals) and fingers (? ) – Rounded distal ends form knuckles • Each finger, except thumb, has 3 phalanges: – Proximal phalanx – Middle phalanx – Distal phalanx
Pelvic Girdle • Composed of sacrum, coccyx, and 2 coxae (hipbones) • Coxae have 3 distinct parts: – Ilium – Ischium – Pubis
Pelvic Girdle, continued…. . • Coxae parts fuse together in the acetabulum, a cup-shaped area on the lateral surface of the hip that receives the head of the femur.
Ilium • Largest and uppermost portion of the coxa • The upper edge is called the iliac crest • Joins the sacrum at the sacroiliac joint • Anterior superior iliac spine- the bony prominence you feel as your “hipbone”
Ischium • Forms the lowest portion of the coxa • Ischial tuberosity – Points posteriorly AND downward – Supports the weight of the body when sitting • Ischial spine – a sharp projection above the ischial tuberosity, near the junction of the ischium and ilium
Pubis • Anterior portion of the coxa • Two pubic bones join midline at the symphysis pubis joint • Pubic arch – Angle formed by pubic bones below the symphysis pubis – Arch is wider in females
