The Appendicular skeleton

Phalanges

14

Each digit has.... phalanges The big toe (hallux) has two.....

3 proximal and distal

Metatarsals

5

Metacarpals

5 bones

Tarsals Talus

7 bones Articulates the tibula and fibula to form the ankle joint

Ischial tuberosity

A rough area in the ischium

What direction do you suppose the shoulder is most likely to dislocate?

Anterior or inferior. Difficult to dislocate superiorly because of acromial process. And posteriorly because of coracoid process.

Olecranon process

Articulates with the olecranon process of the humerus posteriorly

Humerus

Bone of the upper arm

Compare and contrast the femur and the humerus? What do they have in common?

Both of them connect to joints. Difference is that the femur is bigger.

Condyle at the distal end of the humerus articulates with the head of radius

Capitulum

Trochlea

Condyle on the distal end of humerus articulates with the trochlea notch which connects to proximal end of ulna

Which bones articulate with the pelvis

Femor and sacrum

Compare and contrast the bones of the hand and the foot

Foot= tarsals and metatarsals Hand= carpals and metacarpals

Intertubercular groove

Groove formed by the greater and lesser tubercles

Distal features of Ulna

Head of Ulna Styloid process of the ulna

What do you notice about the location of the head of the radius and head of the ulna?

Head of radius are opposite to ulna head. Head of radius is more proximal to head of ulna

Obturator foramen

Large anterior opening of the pelvis

Opposite to the medial epicondyle

Lateral epicondyle

Deltoid tuberosity

Located on the shaft of the bone

Most anterior part of the pelvic bone Articulates of the two pubic bones anteriorly

Pubic bone Pubic crest

Which bone articulate with the distal end of humerus

Radius and Ulna

Which bone participates more in the wrist?

Radius more in the wrist

caracoid process

Serves as a site for muscle attachment of the upper limb muscles

peripheral borders of scapula

Superior, medial, lateral

What do you suppose the difference between the anatomical neck and the surgical neck?

The anatomical neck slightly below the head. In the surgical neck hermoral fractures occur

Calcaneus

The heel bone and the attachment Achilles

What bone articulates with the scapule?

The humerus and the clavical

Which bones form the pelvis?

The illium, ischium, and pubic bone

What runs beneath the medial epicondyle

The large ulnar nerve

Which bone participates more in the knee? Which bone participates more in the ankle?

Tibia in both

What makes up the pelvic gridle

Two pelvic bones and the sacrum

You are treating a patient with a recent hip fracture. Where do you suppose a hip fracture might actually occur

Typically on the neck of the femor

Which bone participates more in the elbow?

Ulna more in the elbow

Head of the radius

articulates with capitulum of humerus

Clavicle

collar bone

Acromial Process

connects with the clavicle posteriorly forming acromioclavicular joint

Ulna Coronoid process articulates with the

coronoid process fossa of the humerus anterioly

head of ulna is the only bone with a

distal head

Illiac crest

large, fanned area of the illeum

Radius

lateral bone of the forearm

Ulna

medial bone of the forearm (participates in both the elbow and wrist joints)

Hand contins

meta carpals and phalanges

Olecranon fossa, triangular depression on the

posterior side of the humerus, receives the olecranon process of the Ulna

Medial/lateral condyles of the femur are located on the

posterior/distal end of the femur articulate with tibia

Greater/lesser trochanters in the femur are located on the

proximal end of femur, muscle attachment

Ulna Trochlear notch located near the

proximal end of the ulna, articulates with the trochlea

Each digit has 3 phalanges The thumb only has

proximal, middle, and distal 2 distal and proximal

What bone articulates with proximal end of the humerus

scapula

The ankle consist of

tarsals, carpals, and talus

Radial tuberosity located on the proximal end of

the shaft

Coronoid fossa is superior to the

trochlea, receives the trochlea

Proximal features of the ulna consist of

trochlear notch, coronoid process, olecranon process

Carpal bones

two rows of 4 for a total of 8 carpal bones

Foot consist of

Metatarsals and phalanges

greater tubercle and lesser tubercle

Opposite of head of humerus
