Refer to individual human bones and to the articulated human skeleton. Study
the following bones and bony landmarks.
Vertebrae
Distinguish between cervical , thoracic , lumbar
and
sacral vertebra
, identify an
atlas and an axis . On each vertebra identify the following bony landmarks:
body ,
transverse process , spinous process
, articular processes
,
articular facets and
vertebral foramen . Find the odontoid process (dens)
on the axis and the
transverse costal facets
and costal demifacets on a thoracic vertebra and the
transverse foramen
on a cervical vertebra. On the vertebral column identify the
intervertebral foramina and the sacral foramina . Identify
the cervical, thoracic, lumbar and sacral curvatures.
Ribs
Identify head
, neck , tubercle , angle,
subcostal groove , and body . On the
articulated skeleton identify the true, false and floating ribs.
Sternum
Identify the segments called sternebrae. The wide superior segment is the
manubrium .
The body (gladiolus) is made up of four central sternebrae. The joint between
the manubrium and the gladiolus is the sternal angle (angle of Louis) .
The inferior most sternebra is the
xiphoid process .
Scapula
Identify the spine , acromion , metacromion (cat only) ,
supraspinous fossa ,
infraspinous fossa , subscapular fossa , glenoid cavity , coracoid process ,
suprascapular notch , superior angle , inferior angle
, supraglenoid tubercle
,
infraglenoid tubercle
, and vertebral border (medial border) .
Clavicle
Identify the acromion end (distal end)
and the sternal end
(proximal end) .
Skull
On the occipital bone locate the occipital condyles
, nuchal lines
and the
external occipital
protuberance . Identify the mastoid process
of the temporal bone.
Identify the above on the articulated cat skeleton.
