Document Summary
Baker | fors 3331 | spring 2017 | lecture 20 | page 1. The longest, heaviest, strongest bone in the body. Supports all of the body"s weight during standing, walking, and running. Articulates with the acetabulum of the innominate at the hip joint. Can be flexed, extended, abducted, adducted, and medially and laterally rotated. Articulates with the patella (kneecap) and tibia at the knee joint: where the leg can be flexed and extended. Ossifies from 5 centers: the shaft, head, distal end, and two trochanters. When in the anatomical position it"s at an angle: the head points toward the hip and keeps the knee in line with the body. Head - rounded, proximal end that articulates with the acetabulum: more spherical than the humeral head, very dense. Greater trochanter - large, blunt, non-articular process on the lateral, proximal side interest located on the posterior side: the point of insertion for the gluteus medius, gluteus minimum, and piriformis.
