the subscapular fossa is on the
a. posterior surface
b. anterior surface
the subscapular fossa is on the anterior surface

2 in forearm (radius & ulna)
27 in hand/wrist
what is the longest and strongest bone of the upper limb?
humerus
what is the only bone in the arm (technically)?
humerus

GO GO GO
what is a condyle?
CONDYLE
"knuckle' or rounded projection at the end of a bone that articulates to another bone
what is the epicondyle?
EPICONDYLE
rounded projection at end of the bone, located on or above the condyle & usually attachment for ligaments & tendons
which of the following stuctures is not on the anterior of the humerus?
a. capitulum
b. radial fossa
c. coranoid fossa
d. olecranon fossa
the olecranon fossa is on the posterior of the humerus. the rest are on the anterior
what 2 bones are in the forearm?
radius + ulna = forearm
the radial head of the proximal radius interfaces with which part of the humerus?
the radial head of the proximal radius interfaces with the CAPITULUM of the humerus
the anterior coranoid process & posterior olecranon process interface with which part of the humerus?
the anterior caronoi and posterior olecranon process of the proximal ulna interface with the trochlea of the distal humerus
what is interosseous membrane (hint: in 2 limbs!)?
INTEROSSEOUS MEMBRANE
interconnects the radius & ulna
also interconnects the tibia & fibula
which bone is responsible for forming most of the joint with the humerus?
the ulna forms most of the joint with the humerus
what type of joint allows the forearm to bend on the arm?
hinge joint
what kind of cartilage separates the ulna from the carpals
fibrocartilage separates the ulna from carpals
which bone plays a key role in hand/wrist movement?
radius
what is the pollex?
finger #1, the thumb, numbering of the metacarpals start at the pollex
what are the 3 parts of a metacarpal?
base, shaft, head
what are the 3 parts of the phalanges?

ACETABULUM
part of the pelvic that attaches to the head of the femur
the lower limbs have MORE/LESS freedom of movement and is MORE/LESS stable than the arms
the lower limbs have less freedom of movement but is more stable than the arms
where is the sacroiliac joint?
it articulates the sacrum with the hips
where is the pubic symphysis?
pubic symphysis (made of fibrocartilage) articulates the hips anteriorly
which bones are in the pelvic girdle?

1 sacrum
1 coccyx
3 part of the coxal bones:
COXAL (HIP) has:
ilium (superior region)
pubis (on top, anterior)
ischium (anterior)
what is the iliac fossa?
the basin like hole in the top back
what is the iliac crest?
