Ch 8 Skeletal and Upper Appendicular Flashcards
appendicular section
outer body
axial section
skull and vertebrae
pectoral girdle
- Supports the upper limb
- Attachment of muscles that move arm
clavicle
- Sternal (medial) end connects to sternum
- Acromial (lateral) end attaches to scapula
clavicle ligaments
- Conoid tubercle
- Lateral
- Costal tuberosity
- Medial
where does clavicle connect
acromiclavicular joint (AC Joint)
sight of most fractures
Scapula
flat bone
3 borders and 3 angles
glenoid cavity
spinal scapula bone
two bumps = acromion process and corocoid process
3 borders of scapula
- Superior border
- Medial border
- Lateral border
3 angles of scapula
- Superior angle
- Medial angle
- Lateral angle
glenoid cavity
holds the humerus
Supraglenoid tubercle (superior edge)
- Bicep
Infraglenoid tubercle (inferior edge)
- Tricep
number of upper limb bones
30
main arm bones
humerus
radius
ulna
carpals
meta carpals
phalanges
2 ends of humerus
proximal end
distal end
proximal end parts of Humerus
humerus end
anatomical neck
surgical neck
greater tubercles
lesser tubercles
Intertubercular sulcus
humerus head
connects to glenoid cavity
anatomical neck
right below humerus head
younger people break
surgical neck
below anatomical neck
older people break
greater and lesser tubercles
- Top corner bumps of humerus
Intertubercular sulcus
- Between greater and lesser tubercle
Distal end of Humerus
condyles
Fossae for projections of forearm bones
Condyles
- trochlea and capitulum articulate w forearm bones
Hinge part of arm
Medial and lateral epicondyle
Fossae for projections of forearm bones
Radial fossa
