What is the difference between the anatomical neck and surgical neck of the humerus?
Anatomical = inferior of the head (area where the diaphysis joins with the proximal epiphysis
Surgical = inferior to the greater and lesser tubercles
Name the bones that are located in the palm of the hand.
metacarpals
Which bone forms the anterior portion of the pelvic bone?

When you place your hands on your hips, what structure are they rested upon?
iliac crests
How does the structure of the pubic arch, the greater sciatic notch, and the sacrum differ between males and females?
Pubic arch is broader in females than males.
Greater sciatic notch is wider and shallower in females.
Sacrum is wider, shorter, and more curved in females.

Acetabulum of the hip bone articulates with the head of the femur.
What structures form the two bony “bumps” on either side of your ankle?
medial malleolus of the tibia and lateral malleolus of the fibula

tibia
Which bone is the talar shelf located on?
calcaneus
Which bone is the tibial tuberosity located on?
tibia
What is the keystone of the medial longitudinal arch of the foot?
anterior portion of the talus
How do the arches of the foot distribute body weight?
anteriorly to the heads of the metatarsals and posteriorly to the heel
In males, what changes in the skeleton occur at puberty?
skeleton becomes more robust
In females, what changes in the skeleton occur at puberty?
pelvis broadens
Considering what you know about how the hip bones form, why can hip dysplasia be successfully treated by splinting if applied early?
3 hip bones fuse together at the acetabulum during childhood.
Splinting holds the femoral head in place so the acetabulum and surrounding ligaments can form normally.
What is true about the bones in the forearm?
The ulna is the medial bone.
The radius is the lateral bone.
The radius forms part of the wrist joint.
What bony features are in or near the hip joint?
acetabulum, greater trochanter and neck of femur
What bone is a sesamoid bone found in the lower limb?
patella
Where are the greater and lesser tubercles located?
humerus
Where is the lateral malleolus?
distal portion of the fibula
What bone of the axial skeleton does the pectoral girdle attach?
sternum
What bone features include the glenoid cavity and acromion?
scapula
What bone features include the ala, crest, and greater sciatic notch?
ilium
What membranous bone transmits forces from upper limb to thoracic cage?
clavicle fracture
What bone of the pelvic girdle articulates with the sacrum?
ilium
What bone bears weight during sitting?
ischial
What is the most anteroinferior bone of the pelvic girdle?
pubis
What bone of the axial skeleton contributes to the pelvic girdle?
pubis
What bone articulates with the acetabulum and the tibia?
femur
What bone’s malleolus forms the lateral aspect of the ankle?
fibula
What bone articulates with the carpal bones of the wrist?
radius
What are the wrist bones?
carpals
What bone is shaped like a monkey wrench?
ulna
What bone articulates with the capitulum of the humerus?
radius
What bone’s largest bone is the calcaneus?
tarsals
What bone is involved in the formation of hip bones?
ischium, ilium and pubis
In the forearm, the radius is what bone?
lateral
In the forearm, the radial notch of the ulna points in which direction?
laterally
The scaphoid and lunate articulate with what?
radius
List 3 differences between the male and female pelves.
Define and distinguish the true pelvis from the false pelvis.
True pelvis: forms a deep bowl containing the pelvic organs
- lies inferior to the pelvic brim
False pelvis: part of the abdomen and contains abdominal organs
- superior to the pelvic brim
Describe the difference between the fibia and the tibula.
fibula: smaller and thinner
- lateral to the leg
tibia: larger and stronger of the two bones
Describe the location of lesser trochanter.
near the top of the femur where the femoral shaft meets the femoral neck
- just below the greater trochanter
Describe the location of intercondylar eminence.
On the tibia between the tibial condyles
Describe the location of capitulum.
On the humerus on the distal lateral side
- adjacent to the trochlea
Describe the location of olecranon.
On the ulna at the proximal end
- prominent bony tip of the elbow
Describe the location of acromion.
On the scapula at the highest point of the shoulder
Describe the location of capitate.
One of the 8 carpal bones at the wrist
- proximal row carpal bones
- centrally within the wrist joint between the proximal and distal rows of carpal bones
Describe the location of navicular.
Part of the tarsal bones of the foot to contribute to the arch structure
Which body regions do anatomists call the arm and the leg?
arm = shoulder to elbow
