Foundations of Functional Anatomy for Physiotherapy Practice
Major bony landmarks of the skeleton
This background material needs to be practiced regularly to ensure that you
are confident and competent in identifying all of the major bony landmarks
presented and their importance.
The information in this section is the starting point on which tutors will build
over the coming weeks.
As you will need to be able to describe the location of anatomical structures
you will need to be able to pronounce all of the new words you find here. It
is not unusual while learning a new language to struggle with this. If you are
having difficulties please seek out support from one of the module tutors.
Major Bony Landmarks
The pelvis
a. The iliac crest forms the distal attachment point for several major muscles
of the trunk
b. This anterior surface of the ilium is the iliac fossa which is the proximal
attachment point for iliacus one of the flexor muscles of the hip.
The posterior surface of the ilium is the proximal attachment point for all
three of the gluteal muscles.
c. Is the anterior superior iliac crest (ASIS). This is easily palpated on most
people and is the proximal attachment point of the muscle sartoruis
d. Lying below the ASIS is the anterior inferior iliac crest (AIIS) which
forms the proximal attachment point of rectus femoris one of the
quadriceps muscle group
e. Is the ischial tuberosity on the posterior aspect of the pelvis. This is the
proximal attachment point for the three muscles that make up the
hamstring group.
f.
Is the pubic tubercle
NB the symphysis pubis is the cartilaginous joint that joins the pelvis
anteriorly between the two pubic bones.
g. Is the sacrum which sits between the two ilia to form the large stable
sacroiliac joints on the posterior aspect of the pelvis
The 5 lumbar vertebra are stacked above the sacrum. The 5th (L5) has local
ligament attachments the sacrum and the ilium

The elbow is formed by the distal end of the humeus and the proximal end of
the radius on the lateral side and the ulna on the medial side.
NB To help you orientate the thumb is on the lateral side

attachment point for a group of tendons called the common extensor
origin.
b. The capitulum on the distal surface of the humerus that articulates with
c the head of the radius.
c. Is the head of the radius which articulates with the capitulum above
and also with the proximal ulna to form the superior radio ulnar joint.
(The superior radioulnar joint is one of only two pivot joints in the body).

biceps brachii muscle
e. Medial epicondyle of the distal humerus. This is the proximal

Forearm, Wrist and Hand
The forearm is made up of the radius and the ulna joined proximally
by the superior radioulnar joint and distally by the inferior radioulnar
joint.
Movement of these two joints occurs as a single movement. They
are responsible for our ability to turn our palm upwards (supination)
and downwards (pronation)
Between the shafts of both bones there is an interosseous
membrane which helps to hold them together and the provide
attachment for muscles.
a. Olecranon process
b. Radial tuberosity
c. Ulna styloid
d. Radial styloid
e. The bones of the proximal and distal carpal rows (known
collectively as the carpus)
The curved concave surface of the distal radius and ulna forms the
wrist joint with the convex surface of the proximal carpal row.
f.

the small muscles of the hand and thumb)
g. The phalanges (note the fingers all have three phalanx while
the thumb has only two)
