The lateral (acromial) end: flat,
The medial (sternal) end: quadrangular
Which two bones form the acromioclavicular joint ?
Clavicle bone and the acromial process of the scapular bone
Describe the superior surface of the clavicle :
Smooth
General shape of the clavicle is :
S shape

B
Describe the location for each of the following:
Trapezoidal line
Conoid tubercle
Subclavian groove
-Trapezoidal line and conoid tubercle: lateral third of the inferior surface of the clavicle
- Subclavian groove: middle part of the inferior surface of the clavicle

Spine
What structure is on the lateral angle of the scapula ?
Glenoid cavity
Which of the following cannot be seen from a posterior view of the scapula :
A)spine
B)Acromion
C) superior angle
D) coracoid process
D
Which border is the supra scapular notch present on ?
Superior border
Which surface is the sub-scapular fossa present on ?
Anterior (costal) surface
Which surface is the “crest of the spine” present on ?
Posterior surface of the spine process
The region between the glenoid cavity and the spine is the
Spenogelnoid notch
Constriction between the head and the greater and lesser tubercles :
Anatomical neck
Which tubercle has 3 muscles attached to the superior and posterior surfaces of it?
Name the muscles
-Greater tubercle
-Sup facet: for Supraspinatus ms -Middle facet: for Infraspinatus ms -Inf facet: for Teres minor
Which tubercle is anterior in the humerus?
Lesser tubercle
What muscle is present in the inter-tubercular sulcus ?
Bicep muscle
Which fracture location would cause a haemorrhage or nerve damage risk on the humerus and why?
Surgical neck
Because the axillary n. (which supplies the deltoid muscle) and the post. circumflex numeral art. Are related to it.
Shallow groove on the POSTERIOR surface of the humerus:
Radial groove (for the radial nerve and deep brachial artery)
Deltoid tuberosity location :
Middle part of the lateral surface of the humerus
articular part of distal humerus that lies medially:
articulates with :
Trochlear
Ulna
articular part of distal humerus that lies laterally:
articulates with :
Capitulum
Radius
fossa superior to the capitulum on the
anterior surface of the humerus.
Radial fossa
fossa superior to the trochlea on the anterior surface of the humerus.
Coronoid fossa
superior to the trochlea on the posterior surface of the humerus.
Olecranon fossa
The radius head margin of the disc articulates ________ly with the radial notch of the ________ bone to form superior radioulnar joint.
- Medially
- Ulna
Structure between the head and the radial tuberosity on the radius bone :
The neck
Border that is a continuation of the radial tuberosity
Anterior border
Border that forms the oblique line
Anterior border
Which radial surface is NOT smooth ?
A) anterior
B)posterior
C) lateral
D) all are smooth
C ( there is a oval roughening on the middle of the lateral surface)
How many surfaces on the distal end of the radial bone ?
5
Which radial surface is the Styloid process on ?
Lateral
Which carpal bones articulate with the radius ?
Scaphoid and lunate
The tuberosity of ulna is rough area on
anterior surface of the coronoid process.
__________ is a fossa that lies inferior to the radial notch
Supinator fossa
The anterior surface of the ulna is smooth, except :
distally where there is a prominent linear roughening.
Which side are the the metacarpals numbered from ?
Lateral
Which scapular border is thick and oblique ?
Lateral
Linear roughening if the ulna is on which surface ?
Anterior surface distal
On the posterior aspect of the ————— there is the greater sciatic notch
Ilium
The pubic crest extends ———— to form the pubic tubercle
Laterally
The body weight while sitting falls on :
Ischial tuberosities
