Summary Anatomy of lower limb

Bones of the Lower Limb :


* The bones of the lower limbs consist of :
a. the pelvic girdle
b. those of the thigh
c. the leg
d. the foot


- Bones of the Pelvic Girdle :


* The pelvic girdle is composed of four bones :
a. the two hip bones
b. the sacrum
c. the coccyx


* The pelvic girdle provides a strong and stable connection between
the trunk and the lower limbs; it has to be strong because of the
large weight it carries.

,* It is interesting to compare the pelvic girdle with the shoulder girdle
because the latter is relatively unstable but possesses a great deal
more mobility than the pelvic girdle.

* The two hip bones articulate with each other anteriorly at the
symphysis pubis and posteriorly with the sacrum at the sacroiliac
joints.


* The pelvic girdle with its joints forms a strong basin-shaped
structure called the pelvis.


* The pelvis is divided into two parts by the pelvic brim, which is
formed by the sacral promontory behind.


* The iliopectineal lines laterally, and the symphysis pubis anteriorly.


* Above the brim is the false pelvis, which forms part of the abdominal
cavity.


* Below the brim is the true pelvis.
