The ______ form the palm of the hand, and the heads of these bones form the knuckles.

Metacarpals

surface on the radius that receives the head of the ulna

Ulnar notch

deep socket in the hip bone that receives the head of the thigh bone

acetabulum

lateral end of the spine of the scapula; clavicle articulation site

acromion

largest tarsal bone

calcaneus

The ______ are the wrist bones

carpals

a roughened area on the lateral humerus: deltoid attachment site

deltoid tuberosity

is the area medial to the flaring iliac bones; it lies superior to the pelvic brim.

false pelvis

longest, strongest bone in body

femur

thin, lateral leg bone

fibula

superiormost margin of the hip bone

iliac crest

fuse to form the hip bone

ilium ischium pubis

rough projection that supports body weight when sitting

ischial tuberoisity

lateral ankle projection

lateral malleolus

Are the bones of the leg shown above from the left or from the right leg?

left

notch loacted inferior to the ischial spine

lesser sciatic notch

small bump on the humerus, often called the "funny bone"

medial epicondyle

medial ankle projection

medial malleolus

bones forming the instep of the foot

metatarsals

opening in hip bone formed by the pubic and ischial rami

obutrator foramen

posterior depression on the distal humerus `

olecranon fossa

kneecap

patella

Proximal row of wrist bones from lateral to medial

pisiform, truquetrum, lunate, scaphoid

point where the hip bones join anteriorly

pubic tuberosity

surface on the ulna that receives the head of the radius

radial notch

joint between axial skeleton and pelvic girdle

sacroiliac joint

tarsal bone that "sits" on the calcaneus

talus

tarsal bone that articulates with the tibia

talus

ankle bones

tarsals

The upper limb is formed by

the humerus, radius and ulna

medial condyle of the humerus that articulates with the ulna

trochlea

is the region inferior to the pelvic brim which is encircled by bone.

true pelvis

Pectoral girdle

-flexibility most important -lightweight -insecure axial and limb attachments

Each hand has ____ finger bones, called _____

17, phalanges

lateral rounded knob on the distal humerus

Capitulum`

hooklike process; biceps brachii attachment site

Coracoid processe

FOOSH is an acronym that stands for Fall on Outstretched Hand. Discuss possible fractures and dislocations that might occur with an injury of this type.

It is very common to break the hamate and pisiform carpal bones of the wrist; dislocations of the elbow are common in this type of fall.

. A single finger bone is called a

Phalanx

Describe some of the features of the female pelvis that provide for compatibility with vaginal birth

The female pelvis is tilted forward; adapted for childbearing; the cavity of the true pelvis is broad, shallow, and has a greater capacity to allow for passage of the child through the pelvic outlet

Your X-ray exam reveals that you have fractured your fibula. Your physician remarks, "Well, it's better than breaking your tibia." Explain why a fracture of the tibia would be worse than a fracture of the fibula

The fibula provides lateral support and stability for the fibula but it does not play a large role in weight bearing, as does the fibula.

Explain how you can tell which side of the body they are from

The lateral malleolus forms the bulge of the ankle; this is the posterior view of the leg so therefore it must be from the left leg.

Name the two bone markings that form the proximal radioulnar joint.

The radial head of the radius and the radial notch on the ulna

Name the two bone markings that form the distal radioulnar joint

The ulnar head of the ulna and the ulnar notch on the radius.

The bones that form the pectoral girdle are the

clavicle and scapula

anterior depression, superior to the trochlea, that receives part of the ulna when bending at the elbow

cronoid fossa

depression in the scapula that articulates with the humerus

glenoid cavity

sites of muscle attachment on the proximal femur

greater and lesser trochanters

permits passage of the sciatic nerve

greater sciatic notch

list the distal row of wrist bones from lateral to medial

hamate, capitate, trapezoid, trapezium

shinbone

tibia

weight-bearing bone of the leg

tibia

point where the patellar ligament attaches

tibial tuberosity
